PreparationtAnalytical Method Verification The SOP stated above has been prepared based on technical research and testing conducted by General Engineering Laboratories, LLC and with guidance from the regulatory documents listed in this 'Method/Analysis Information" section.

System Confieuration The ICP-MS analysis was performed on a Perkin Elmer ICP-MS ELAN 9000. The instrument is equipped with a cross-flow nebulizer, quadrupole mass spectrometer, and dual mode electron multiplier detector. Internal standards of scandium, germanium, indium, and tantalum were utilized to cover the mass spectrum. Operating conditions are set at 1400W power and combined argon pressures of 360+1-7 kPa for the plasma and auxiliary gases, and 0.85 IUniin carrier gas flow, and an initial lens voltage of 5.2.

Calibration Information Instrument Calibration All initial calibration requirements have been met for this sample delivery group (SDG).

CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.

ICSAIICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.

Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.

Continuing Calibration Verification (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.

Ouality Control (OC) Information Method Blank (MB) Statement The MB analyzed with this SDG met the acceptance criteria.

Laboratory Control Sample (LCS) Recovery The LCS spike recoveries met the acceptance limits.

Quality Control (QC) Sample Statement Sample 120208001 (S153-176-2,3,4 and 5) was selected as the quality control (QC) sample for this SDG.

Matrix Spike (MS) Recovery Statement The percent recoveries (%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria.

Duplicate Relative Percent Difference (RPD) Statement The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance criteria of 20%

when the sample is 5X the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control of +/-RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The SDILT failed for B. All-ICP-MS.

The serial dilution is used to assess matrix suppression or enhancement. Raw element concentrations 25x the IDL for CVAA. SOX the IDL for ICP and 10OX the IDL for ICP-MS analyses are applicable for serial dilution assessment All applicable analytes did not meet the established criteria of less than 10% difference (%D). All-ICP-MS.

Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology, which assigns the date and time from sample collection of sample receipt Those holding times expressed in hours are calculated in the AlphaLIMS system. Those holding times expressed as days expire at midnight on the day of expiration. All samples in this SDG met the specified holding time.

Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.

14

Sample Dilutions Dilutions are performed to minimize matrix interferences resulting from elevated mineral element concentrations present in soil samples and/or to bring over range target analyte concentrations into the linear calibration range of the instrument The samples in this SDG did not require dilutions.

Preparation Information The samples in this SDG were prepared exactly according to the cited SOP.

Miscellaneous Inrornmation Nonconformance Documentation Nonconformance reports (NCRs) are generated to document procedural anomalies that may deviate from referenced SOP or contractual documents. A NCR was not required for this SDG.

Additional Comments Additional comments were not required for this SDG.

Certification Statement Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless otherwise noted in the analytical case narrative.

Review Validation:

GEL requires all analytical data to be verified by a qualified data validator. In addition, all data designated for CLP or CLP-like packaging will receive a third level validation upon completion of the data package.

N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike cone, by a factor of 4 or more.

A The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptance criteria when the sample is greater than five times'(5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than5X the RL t control limit of+/-

the RL is nsed to evaluate the DUP esult.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Wheri'the analytical method has been pertformed under NELAP cctficafion, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.

QC Information All of the QC samples met the required acceptance limits.

Technical Information:

Holding Time All sample procedures for this sample set were performed within the required holding time.

Preparation Information All preparation criteria have been met for these analyses.

Sample Re-prep/Re-analysis Samples 1200693213 (S152-157-2,3,4,5), 120208002 (SI52-157-2,3,4 and 5) were recounted due to high relative percent difference/relative error ratio.

Chemical Recoveries All chemical recoveries meet the required acceptance limits for this sample set.

Gross Alpha/Beta Preparation Information High hygroscopic salt content in evaporated samples can cause the sample mass to fluctuate due to moisture absorption. To minimize this interference, the salts are converted to oxides by heating the sample under a flame until a dull red color is obtained. The conversion to oxides stabilizes the sample weight and ensures that proper alpha/beta efficiencies are assigned for each sample. Volatile radioisotopes of carbon, hydrogen, technetium, polonium and cesium may be lost during sample heating.

BD Flag for results below the MDC or a flag for low tracer recovery.

E Concentration of the target analyte exceeds the instrument calibration range.

H Analytical holding time exceeded.

J Indicates an estimated value. The result was greater than the detection limit, but less than the reporting limit U Indicates the target analyte was analyzed for but not detected above the detection limit.

Ul Uncertain identification for gamma spectroscopy.

X Lab-specific qualifier-please see case narrative, data summary package or contact your project manager for details.

h Sample preparation or preservation holding time exceeded.

N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.

    • Indicates analyte is a surrogate compound.

^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.

Preparation/Analytical Method Verification The SOP stated above has been prepared based on technical research and testing conducted by General Engineering Laboratories, LLC. and with guidance from the regulatory documents listed in this 'Method/Analysis Information" section.

System Configuration The ICP-MS analysis was performed on a Perkin Elmer Elan 6100E inductively coupled plasma mass spectrometer (ICP-MS). The instrument is equipped with a cross-flow Page 12 of 77

nebulizer, quadrupole mass spectrometer, and dual mode electron multiplier detector.

Internal standards of scandium, germanium, indium, and tantalum were utilized to cover the mass spectrum. Operating conditions are set at 1400W power and combined argon pressures of 3607 kPa for the plasma and auxiliary gases, and 0.85 Urnin carrier gas flow, and an initial lens voltage of 5.2.

Calibration Information Instrument Calibration All initial calibration requirements have been met for this SDG.

CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.

ICSAIICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.

Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.

Continuing Calibration Verification (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.

Quality Control (OC) Information Method Blank (MB)jStatement The MB analyzed with this SDG met the acceptance criteria.

Laboratory Control Sample (LCS) Recovery The LCS spike recoveries met the acceptance limits.

Quality Control (QC) Sample Statement The following sample was selected as the quality control (QC) sample for this batch:

113889001 (Leachate).

Matrix Spike (MS) Recovery Statement The percent recoveries (%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria Duplicate Relative Percent Difference (RPD) Statement The relative percent difference (RPD) obtained from the designated sample duplicate (DUP) is evaluated based'on acceptance criteria of 20% when the sample is >5X the Page 13 of 77

contract required detection limit (RL). In cases were either the sample or duplicate value is less than 5X the contract required detection limit (RL), a control of RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The serial dilution is used to assess matrix suppression or enhancement. Raw element concentrations 25x the IDL for CVAA, 50X the IDL for ICP and I OOX the IDL for ICP-MS analyses are applicable for serial dilution assessment. All applicable analytes met the established criteria of less than 10% difference (%D).

Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology, which assigns the date and time from sample collection of sample receipt. Those holding times expressed in hours are calculated in the AlphaLIMS system. Those holding times expressed as days expire at midnight on the day of expiration. All samples in this SDG met the specified holding time.

Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.

Sample Dilutions Dilutions are performed to minimize matrix interferences resulting from elevated mineral element concentrations present in soil samples and/or to bring over range target analyte concentrations into the linear calibration range of the instrument. The samples in this SDG did not require dilutions.

Preparation Information The samples in this SDG were prepared exactly according to the cited SOP.

Miscellaneous Information Nonconformance Documentation Nonconformance reports are generated to document any procedural anomalies that may deviate from referenced SOP or contractual documents. No NCR was generated with this SDG.

Additional Comments Additional comments were not required for this SDG.

Certification Statement Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless otherwise noted in the analytical case narrative.

Page 14 of 77

Review Validation GEL requires all analytical data to be verified by a qualified data validator. In addition, all data designated for CLP or CLP-like packaging will receive a third level validation upon completion of the data package.

Gross Alpha/Beta Preparation Information Page 34 of 77

High hygroscopic salt content in evaporated samples can cause the sample mass to fluctuate due to moisture absorption. To minimize this interference, the salts are converted to oxides by heating the sample under a flame until a dull red color is obtained. The conversion to oxides stabilizes the sample weight and ensures that proper alphalbeta efficiencies are assigned for each sample. Volatile radioisotopes of carbon, hydrogen, technetium, polonium and cesium may be lost during sample heating.

Appendix 5 COLOG Borehole Geophysics Report, Hydrophysical Sampling Data Quality Assessment

Data Quality Assessment of Hydrophysical Sampling Results Collected in Summer of 2004 CH2M HILL has performed a data quality assessment (DQA) of the results of borehole sampling conducted during hydrophysicalTW' logging at the Connecticut Yankee Atomic Power Company (CYAPCo) Haddam Neck Plant (HNP). Discrete point samples were collected using a downhole sampling device just above each identified water-producing zone identified by the fluid electrical conductivity profiles and temperature changes recorded by the hydrophysicalTM logging technique. The fluid samples were procured just above each identified flow zone to insure complete mixing of the inflowing formation waters fluid moving up to the pump placed inside the surface casing in order to obtain a sample representative of each discrete depth point.

The purpose of collecting and analyzing discrete point samples at the HNP was to provide screening of the bedrock interval for the vertical distribution of tritium, confirm the analytical results and overall characterization of the boreholes obtained from previous packer testing, and determine potential screen intervals for water quality monitoring.

The DQA was performed as outlined below. The data set generated from the borehole sampling was evaluated against criteria for measurement precision, accuracy, representativeness, completeness, and comparability to determine data validity and usability. The following summarizes the results of the DQA.

Summary of Data Collection Activities Fluid replacement and fluid-column conductivity logging, or hydrophysical T rm logging, involves electrical conductivity logging of the fluid column over time after the borehole fluid has been diluted or replaced with de-ionized water. Periodic electrical conductivity logs show formation fluids and possible contamination reentering the borehole as a function of the hydraulic conductivity of the surrounding rocks. Hydrophysical logging is used to determine flow magnitude and direction under both ambient and pumping conditions to identify hydraulically conductive intervals to within one wvellbore diameter. The data can be analyzed with a multi-parameter, finite difference model to produce hydraulic conductivity measurements that compare well with hydraulic conductivity values calculated from packer tests (Keys, 1997). The hydrophysicalTM logs were used to measure the magnitude and direction of flow, identify possible fluid entry and exit points in the boreholes to complete the bedrock characterization effort, providing confirmation or alternative interpretations of flow conditions measured by the heat-pulse flowmeter surveys and indications of water-bearing fractures by the conventional geophysical logs. Other specific applications of hydrophysicalTM logging for this characterization effort included assessment of possible fracture interconnection within and between boreholes, providing flow measurements to calculate the hydraulic conductivity and transmissivity of specific fractures or intervals, and targeting discrete point sample locations. Discrete point samples are procured via a

downhole sampling device just above each identified water-producing zone identified by flow logging. These fluid samples collected provide an indication of the presence and vertical extent of substances of concern in a borehole.

During the second phase of the geophysical logging program at the HNP, data were collected to confirm the location of water-bearing fractures, refine the understanding of the flow regime in the boreholes, assess fracture interconnection, generate hydraulic conductivity values for specific fractures and intervals, and collect discrete point samples to screen the bedrock interval for the vertical distribution of tritium. The optical camera logging was completed in each borehole prior to the hydrophysical loggingTm to confirm the location and apparent aperture of possible fracture features. Hydrophysical logging'mwas conducted to provide an overall assessment of hydrogeologic conditions and refine previous interpretations of groundwater flow at the facility. The hydrophysical loggingT't technique was conducted in three sequential logging steps:

(1) ambient logging runs prior to de-ionized (DI) emplacement, (2) logging runs immediately after DI water was emplaced in the borehole, and (3) logging runs conducted after DI water was emplaced during low-rate pumping.

The ambient water quality logs are conducted to provide baseline values for undisturbed borehole fluid conditions prior to testing. Multiple logging runs were conducted during each step to provide repeatable profiles of the fluid electrical conductivity and temperature changes in the borehole caused by electrically contrasting water being drawn into the borehole by pumping or native formation pressures.

Based on the water-producing zones identified by the fluid electrical conductivity profiles and temperature changes recorded, discrete point sample locations were then selected to confirm the vertical distribution of tritium in the bedrock interval at the Industrial Area of the HNP. The CYAPCo laboratory at the HNP analyzed these samples. COLOG then calculated interval specific pore water tritium concentrations using a mass-balance equation with the HNP laboratory results and interval specific flow rates from the hydraulically conductiver interval directly below the sample collection depth. These analytical results comprise the hydrophysical sampling conducted during the summer of 2004 and are the focus of this DQA.

The computer programs FLOWCALC and/or BORE II (COLOG, 2004) were utilized to evaluate the inflow quantities of the formation water for each specific inflow location.

FLOWCALC is used to estimate the interval-specific flow rates for the production test results based on "hand-picked" values of fluid electrical conductivity and depth. The values are determined from the "Pumping" and "Pumping during DI Injection logs." Numerical modeling of the reported data is performed using code BORE II. These methods accurately reflect the flow quantities for the identified water bearing intervals (COLOG, 2004).

For interval-specific permeability estimations, COLOG utilizes Hvorslev's 1951 porosity equation in conjunction with the hydrophysicalTM logging results. Several assumptions are made for estimating the permeability of secondary porosity. First, the type of production test COLOG performs in the field may significantly affect the accuracy of the transmissivity estimation. The permeability equation is relatively sensitive to overall observed drawdown.

For a high yield borehole, drawdown will usually stabilize ahd an accurate observed drawdown can be estimated. However, for a low yield borehole, drawdown usually does not stabilize but instead, water level continues to drop until it reaches the pump inlet and the test is complete. In this case COLOG utilizes the maximum observed drawdown. The inaccuracy arises in the fact that overall observed drawdown does not stabilize and therefore is more an arbitrary value dependent on the placement of the pump downhole.

Secondly, in an environment where flow originates from secondary porosity the length of thickness of the fracture network producing water. This assumption of a fracture network producing water versus a porous media is not how the permeability equation was designed to be used. In lieu of a more appropriate equation unknown to COLOG at this time, COLOG utilizes Hvorslev's 1951 porosity equation based on its sensitivity to interval-specific flow which can be measured accurately, drawdown which can be measured accurately in the case of a high yield borehole and its insensitivity to effective radius. The insensitivity to effective radius is critical when an observation well is not available to measure drawdown at a known distance from the subject borehole (COLOG, 2004).

Summary of Data Collected The borehole samples collected were analyzed for tritium by using liquid scintillation counting (the recommended counting method). Two different preparation methods were used: distillation and resin adsorption separation. Of the samples collected, 20 percent were analyzed by the distillation method, 80 percent by the resin adsorption separation method, and four samples were analyzed by both distillation and resin adsorbtion.

Discrete point sampling was conducted at depth in borehole 118A during development pumping at a time-averaged pumping rate of 4.81 gpm after production testing was completed. Eight at-depth samples and one wellhead sample were collected. Samples collected from 40.28, 53.4, 67.5 feet bgs contained the highest concentrations of tritium, while samples collected from 72,108, and 124.7 feet bgs detected tritium at lower concentrations. The HNP laboratory results and the pore water contaminant concentrations derived by COLOG using a mass balance equation are presented in Table 3-1. Discrete point sampling was conducted at depth in borehole 119 during development pumping at a time-averaged rate of 1.41 gpm after production testing was completed. Eight at-depth samples and one wellhead sample were collected. Samples collected from 44, 70, and 82 feet bgs contained the highest concentrations of tritium, while lower values were detected from samples collected from 143,156, 298, and 453.5 feet bgs. The derived pore water contaminant concentrations were significantly elevated compared to the HNP laboratory for the 156, 298, and 453.5 feet bgs samples as noted in Table 3-2. It was determined the lower concentrations reported by the HNP laboratory at 298 and 453.5 feet bgs are more representative of site conditions. The rationale for this assessment of representative analytical results for the lower depths is discussed in detail in provided in the Results of Data Quality Assessment section below.

Discrete point samples were collected at depth in borehole 120 during development pumping at a time-averaged rate of 1.80 gpm after production testing was completed. Seven at-depth samples and one wellhead sample were collected. The sample collected from 77

feet bgs contained the highest concentrations of tritium with much lower levels detected at 85.3 and 99.7 feet bgs (See Table 3-3).

Discrete point samples were collected at depth in borehole 121A during development pumping at a time-averaged rate of 6.75 gpm after production testing was completed. Eight at-depth samples were collected. In summary, samples collected from depths 163 and 173 feet bgs detected tritium at elevated t concentrations. All other samples analyzed were non-detect as shown in Table 3-4.

Results of Data Quality Assessment The Phase II Hydrogeologic Characterization Work Plan (Malcom-Pirnie, 2002) data quality objectives specify goals of "determining the cause, location, nature and condition of release areas and their associated SOCs" and "determining the degree and extent of the resulting plumes". Even though the samples were collected for screening purposes, the data were assessed for precision, accuracy, representativeness, completeness, and comparability. The individual assessment parameters are discussed in the following subsections.

Precision Precision is the measurement of the repeatability of a measurement or measurement technique. Precision is evaluated through analysis of multiple duplicate samples. The following types of duplicate samples are typically assessed:

  • Field duplicate, or split, samples that are collected in the field and submitted to the laboratory as blind samples (i.e., not identifiable to the laboratory as duplicates); and
  • Laboratory duplicate, or replicate, samples that are prepared by the laboratory and analyzed by the laboratory to assess internal method precision.

Since the objective of the discrete point sample collection was to screen the bedrock interval for tritium, duplicate and/or field samples were not collected for tritium analysis during the hydrophysicalTM sampling. As part of regularly-scheduled groundwater monitoring activities in future bedrock wells, field and laboratory duplicates will be collected, to assess measurement precision.

Accuracy Accuracy is typically assessed through analysis of known standards and through the analysis of blanks and/or matrix spike samples. No blank and/or matrix spike information was provided by the onsite laboratory to assess accuracy. Measurement calibration is performed in accordance with laboratory procedures.

Representativeness Representativeness refers to the degree to which a data set is actually a sample of a population. In this case representativeness refers to the degree to which the information presented by the data set can be extrapolated to describe the overall site.

Discrete point sample collection during hydrophysical logging is intended to collect samples from specific transmissive intervals in the geologic formation. In zones where the formation

is sufficiently productive to allow complete development of the borehole, consistent with the protocols employed by COLOG, samples of borehole water at identified intervals are considered to be representative of formation water from the identified zones. In some zones, the production of water from the formation under the test conditions is insufficient to fully develop the water within the borehole. In this case, the sample of water collected from the borehole corresponding to that zone is not considered to be representative of formation water. This situation was encountered in the following depth intervals in borehole 119 during hydrophysical testing at HNP (See Table 3-2):

  • 254-ft bgs (interval 253- to 254.5-ft bgs),
  • 298-ft bgs (interval 297.2- to 299.3-ft bgs), and
  • 453.5-ft bgs (interval 456.4- to 456.7-ft bgs).

COLOG uses an arithmetic dilution algorithm to derive an estimated concentration of constituents of interest for zones that are not fully developed. The actual representativeness of these samples, and the concentrations derived from laboratory measurements of those samples is not quantifiable and the derived tritium values should not be compared to other measurements. These values should not be used to represent the formation water quality at those intervals and should rather be used only as indication of the presence or absence of tritium in the borehole at those elevations.

This uncertainty regarding representativeness of samples from zones that did not develop fully is generally confined to zones at substantial depth in the bedrock formation. Those zones exhibiting a low degree of development during hydrophysical testing may be exhibiting other features such as temporary storage of small quantities of borehole water in discontinuous, or "blind" fractures into which tritium-bearing borehole water was forced due to previous placement of the flexible borehole liners. The resulting inability to quantitatively assess the presence or absence of tritium in these poorly developed zones demonstrates the need to establish monitoring capability in those zones to confirm conditions.

In another instance, the pore water tritium concentration calculated from an interval is significantly less than the laboratory analytical results because of a low specific interval flow detected at that depth. The sample procured at 144 feet bgs in BH-121A detected 6,250 pCi/L of tritium by the HNP laboratory, while the resulting pore water tritium estimation using the Mass-Balance equation was "No Detect" (ND) as shown in Table 3-4. This ND calculation is derived because the sample just below 144 feet procured at 163 feet contained 7,230 pCi/L of tritium with 6.47 gpm (aggregate flow below 163 feet) of flow associated with this sample, which comprises approximately 94 percent of the flow measured in the borehole. The sample procured at 144 feet had only an additional 0.18 gpm of flow associated with it. The difference in observed concentrations between the sample at 163 feet and 144 feet, as far as estimations made using the Mass-Balance equation are concerned, is solely the result of the introduction of a certain concentration of tritium into the borehole at 0.18 gpm. The water coming into the borehole must be relatively low in tritium compared to the borehole fluids and steady-state conditions are present at and below this depth, resulting in the ND value for the corresponding water-bearing flow feature. In this case, the

ND pore water tritium concentration is considered representative of the groundwater at depth interval 160.4-160.5.Completeness Completeness refers to the ability of the data set to encompass the entirety of the target systenri. The data should be sufficient to answer the questions that prompted the data collection in the first place. As stated above, the data collected as part of this characterization effort met the hydrophysical/geophysical logging program objectives of screening the bedrock interval for vertical distribution of tritium, providing necessary information to refine the hydrogeologic conceptual site model, assist with the design of the bedrock groundwater monitoring network, and calibrate the upcoming numerical groundwater modeling for the facility.

Eight discrete point samples were collected in each borehole as planned: seven samples collected from water-producing intervals and one wellhead sample per borehole. Valid analytical results from the HNP onsite laboratory were obtained for each sample collected.

Comparability Comparability refers to the degree to which a data set, or single datum can be compared to another measurement for the purposes of assessing change over time or space. Collected samples were analyzed for tritium by using liquid scintillation counting (the recommended counting method) using two different preparation methods: distillation and resin adsorption separation. Twenty percent of the samples were analyzed by the distillation method, 80 percent by the resin adsorption separation method, and four samples were analyzed by both methods. To assess comparabilty, relative percent difference was calculated for each sample for which both preparation methods were used. If the two sample preparation methods are indeed comparable, then the results should compare well when evaluated as duplicate analyses of the same sample.

Seven laboratory duplicates were identified in the data set provided for this sampling campaign. The Relative Percent Difference (RPD) for the laboratory duplicates are summarized in Table 1.

Upon review, the discrete point sample analytical results generated by the CYAPCo HNP laboratory were generally similar to but lower than the pore water contaminant concentrations estimated by COLOG using the mass balance equation. Both sets of concentrations were generally lower than the 2003 and the 2004 packer sampling results. A direct comparison of the discrete point sample results and both rounds of packer sampling results, however, is difficult for some intervals because some packer samples came from 23-ft intervals and some intervals were not sampled by packers because of insufficient seal developed in the borehole; discrete point samples were collected without these limitations.

However, the results from both sampling methodologies are similar, especially between the 2004 packer sampling results in borehole 121A and the discrete point sample results obtained from the same borehole. With the exception of results for the two lower depths sampled in borehole 119, the pore water tritium concentrations estimated by COLOG using the mass-balance equation could be considered representative of the bedrock intervals sampled. Because the flow zones sampled in borehole 119 were not fully developed and the sample dilution corrections made by COLOG for these depths are as described above, the HNP laboratory results for 298 and 453,5feet bgs in this borehole are determined to be more representative of actual concentrations from these discrete bedrock intervals than those derived by COLOG's methodology.

DQA Summary The primary goal of re-sampling boreholes 118A, 119, 120 and 121A was to further characterize the tritium plume at depth and determine potential depth intervals for the bedrock groundwater quality monitoring network.

The data set generated from the 2004 hydrophysicalTM sampling was evaluated against criteria for measurement precision, accuracy, representativeness, completeness, and comparability to determine data validity and usability. Several observations were made concerning the representativeness of pore water tritium concentrations calculated using the mass-balance equation versus the laboratory analytical results in certain flow conditions:

  • Discrete point samples collected and analyzed from zones that did not fully develop under the hydrophysicalTM testing conditions should not be considered representative for assessment of the presence, absence, or relative concentration of tritium.
  • Discrete point samples collected from low flow zones directly above high flow zones may not yield analytical results representative of those intervals.

The following data deficiencies were noted by the DQA:

  • No field duplicate samples were collected to measure precision.
  • No blank and/or matrix spike information was provided by the onsite laboratory to assess accuracy (e.g., blanks, spikes, and standards).

The data collected as part of this characterization effort met the hydrophysical/geophysical logging program objectives and provided necessary information to refine the hydrogeologic conceptual site model, assist with the design of the bedrock groundwater monitoring network, and calibrate the upcoming numerical groundwater modeling for the facility.

HydroPhysicalP Logging Results CYAPCO; Haddam Neck, Connecticut I. Executive Summary The results of the HydroPhysicalT^' logging performed in four boreholes at the CYAPCO identified repeatable fracture and flow patterns in throughout each of the four boreholes.

Ambient horizontal flow was identified in each of the four boreholes while no vertical flow in the bores under ambient conditions was identified. The ambient horizontal flow rates identified on site ranged from 0.0002 to 0.012 gpm. Under pumping conditions each borehole exhibited a similar flow pattern consisting of the dominant water-bearing fractures or features originating in the upper portions of the wellbore - no deeper than 167 feet in three of the four boreholes. In all four boreholes little to no flow was identified below 243 feet. Under pumping conditions the lower portions of the boreholes proved to be of little to no water-bearing capacity. Interval specific transmissivity estimates of the dominant flow features ranged from 0.488 to 30.7 square feet per day. Interval specific transmissivity and FEC estimates are observed to not differ significantly among dominant water-bearing features suggesting an inter-connected network of fractures and features comprising the dominant flow features in these four boreholes.

In three of the four boreholes, the highest concentrations of tritium are observed between the intervals of 45.9 to 88.8 feet.

Please refer to the well tables in each section for each borehole for a complete summary of the HydroPhysicalT^' logging results. All depths reported herein are referenced to ground surface.

II. Introduction In accordance with COLOG's proposal dated July 13, 2004, COLOG has applied HydroPhysicalTlt (HpLTNI logging methods along with downhole sampling and downhole video to characterize the formation waters of four boreholes at the CYAPCO in Haddam Neck, Connecticut. The objectives of the investigation were to:

1) Evaluate temperature and fluid electrical conductivity under pre-testing conditions.
2) Identify and characterize water-bearing fractures and features intersecting the borehole.
3) Characterize and quantify flow in the borehole under both non-stressed (ambient) and stressed (pumping) conditions.
4) Evaluate the vertical distribution of flow and interval-specific permeability for all identified water-producing fractures or intervals.
5) Evaluate the vertical distribution of tritium utilizing downhole sampling.

The four bores hydrophysically logged are: BBH-1 18A, BH-1 19, BH-120 and BH-121A. The boreholes ranged in total depth from 552 to 621 feet. All open boreholes were approximately 6.1 inches in diameter and all had 6-inch surface steel casing installed to bedrock ranging in depth from 17.8 to 98.4 feet. The wellbores were tested under both non-stressed, or ambient, conditions and stressed, or pumping, conditions to fully evaluate the water-bearing intervals intersecting the borehole.

COLOG's logging of the four boreholes was performed over the period of July 19 through August 5, 2004.

Methodology A. HydroPhysical TM Logging (HpLTM)

The HydroPhysicalT^I logging technique involves pumping the borehole and then pumping while injecting into the borehole with deionized water (DI). During this process, profiles of the changes in fluid electrical conductivity of the fluid column are recorded. These changes occur when electrically contrasting formation water is drawn back into the borehole by pumping or by native formation pressures (for ambient flow characterization). A downhole wireline HydroPhysicalTM tool, which simultaneously measures fluid electrical conductivity (FEC) and temperature is employed to log the physical/chemical changes of the emplaced fluid.

The computer programs FLOWCALC and/or BORE II (Hale and Tsang, 1988 and (Daughtery and Tsang, 2000) can be utilized to evaluate the inflow quantities of the formation water for each specific inflow location. FLOWCALC is used to estimate the interval-specific flow rates for the production test results based on "hand-picked" values of FEC and depth. The values are determined from the "Pumping" and "Pumping During DI Injection logs". Numerical modeling of the reported data is performed using code BORE 11. These methods accurately reflect the flow quantities for the identified water bearing intervals.

In addition to conducting HydroPhysicalTN1 logging for identification of the hydraulically conductive intervals and quantification of the interval specific flow rates, additional logging runs are also typically performed. Prior to emplacement of DI, ambient fluid electrical conductivity and temperature (FEC/T) logs are acquired to assess the ambient fluid conditions within the borehole. During these runs, no pumping or DI emplacement is performed, and precautions are taken to preserve the existing ambient geohydrological and geochemical regime. These ambient water quality logs are performed to provide baseline values for the undisturbed borehole fluid conditions prior to testing.

For interval-specific permeability estimations, COLOG utilizes Hvorslev's 1951 porosity equation in conjunction with the HpLTNI results. Several assumptions are made for estimating the permeability of secondary porosity. First, the type of production test COLOG performs in the field may significantly affect the accuracy of the transmissivity estimation. The permeability equation is relatively sensitive to overall observed drawdown. For a high yield borehole, drawdown will usually stabilize and an accurate observed drawdown can be estimated. However, for a low yield borehole, drawdown usually does not stabilize but instead, water level continues to drop until it reaches the pump inlet and the test is complete. In this case COLOG utilizes the maximum observed drawdown. The inaccuracy arises in the fact that overall observed drawdown does not stabilize and therefore is more an arbitrary value dependent on the placement of the pump downhole. Secondly, in an environment where flow originates from secondary porosity the length of the interval is derived from the either the thickness of the fracture down to 0.1 feet or the thickness of the fracture network producing water. This assumption of a fracture network producing water versus a porous media is not how the permeability equation was designed to be used. In lieu of a more appropriate equation unknown to COLOG at this time, COLOG utilizes Hvorslev's 1951 porosity equation based on its sensitivity to interval-specific flow which can be measured accurately, drawdown which can be measured accurately in the case of a high yield borehole and its insensitivity to effective radius. The insensitivity to effective radius is critical when an observation well is not available to measure drawdown at a known distance from the subject borehole.

How to Interpret IlydroPhysicalTm Logs Figure HpL: I below is an example data set. The data represents HpLT`I logs acquired immediately after deionized (Dl) water emplacement for ambient flow evaluation. For ambient flow evaluation the wellbore fluids are first replaced with DI water (termed "emplacement"), then a series of fluid electrical conductivity (FEC) logs are acquired over a period of a time to monitor ground water entering the wellbore under natural pressures and migrating either vertically or horizontally through the wellbore. The borehole fluids are replaced with Dl water without disturbing the ambient free-water level by injecting DI water at the bottom of the borehole and extracting borehole water at exactly the same rate at the free-water surface. However, at the beginning of the DI water emplacement, a slightly depressed free-water level (approximately one tenth of a foot below ambient free water-level) is achieved and maintained throughout the test.

This procedure is implemented to ensure that little to no Dl water is able to enter the surrounding formation during DI water emplacement. By acquiring FEC logs during the emplacement of DI water and by continuously measuring water level with a downhole pressure transducer the emplacement can be properly monitored and controlled to minimize the disturbance of the recorded ambient water. After the borehole fluids are replaced with DI water, the injection and extraction pumps are turned off and in most cases the downhole plumbing is removed from the borehole. A check valve is installed in the pump standpipe to ensure water in the standpipe does not drain back into the borehole. While the plumbing is removed from the borehole Dl water is injected from the top of the borehole to maintain ambient water level. Often a baseline FEC log is acquired during the final stages of the emplacement of DI wvater to provide baseline conditions just before the ceasing of pumping. Figure HpL:I illustrates ambient flow entering the borehole at depths of 150.0 to 152.7, 138.8 to 139.0, 132.7 to 133.4, 122.3 to 123.1 and 118.0 to 118.1 feet. The location of these intervals is illustrated by the sharp increases or "spikes" in FEC. The increase in FEC over time at these four intervals is characteristic of ambient inflow. The upward vertical trend in this inflow is also apparent from the FEC logs. For example, the dominant inflowing zone at 138.8 to 139.0 feet illustrates a major growth in FEC above the inflow "spike",

and little growth below the "spike." The zone at 118.0 to 118.1 feet is the termination of all inflow into the well. The sum of the four inflow zones make up the outflow of this zone, and this value, along with the value of the four inflow zones is computed using code BORE 11.

COLOG uses three types of tests to identify the water-bearing intervals in a borehole under stressed conditions. In the lowest yield environment (less than 0.7 gpm) a slug test approach is utilized. In a relatively low-yield borehole environment, 1-2 gpm, a pump after emplacement (PAE) test is conducted, and in a relatively medium to high-yield environment a pump and inject (PNI) test is conducted. The decision on the type of test to perform on a specific borehole is made in the field based on the ability of the borehole to recover to ambient free-water level when a disturbance in water level is introduced into the well, i.e. inserting tools and/or pluming into the well.

In a low-yield borehole environment a slug or PAE test is utilized to identify the water-bearing intervals under stressed conditions. These tests are similar in protocol and involve first a replacement of borehole fluids with DI water in a manner 'identical to that of the emplacement during an ambient flow evaluation. Often a baseline FEC log is acquired during the final stages of the emplacement of DI water to provide baseline conditions just before the ceasing of injection pumping. Following the cessation of injection pumping, the extraction pump is left used to either pull an instantaneous slug (slug test) or is used to pump at a relatively steady low rate of flow in the borehole (approximately 1-2 gpm). During this time numerous FEC logs are acquired over time. The location of water-bearing intervals is apparent by the sharp increases or "spikes" in

FEC over time. The rate at which these intervals inflow is calculated using BORE II and is based on the rate of increase of mass (area under the curve using the FEC log as the curve). Flow direction is easily determined by tracking the center of mass of the area under the curve. In most cases, if pumping is being conducted flow is traveling up the borehole towards the pump which is situated inside casing.

Figure HpL:2 is an example data set. The data represents IHlpLTmf logs acquired during a PNI test.

The set of FEC logs on the right of this figure (FEC1303, FEC1310, FEC1320, and FEC1329) illustrate the condition of the borehole during development pumping. In the case of this example, the wellbore was stressed at a rate of approximately 10 gpm until a relatively steady-state condition was achieved in the borehole. A steady-state condition is apparent when the FEC logs begin to repeat as they do in figure HPL:2. Repeatable FEC logs indicate that the hydrochemistry of the water inflowing to the borehole is not changing over time (steady-state) and that the flow rates of all inflow zones is also not changing over time. Additionally, the drawdown is monitored continuously to observe a "slowing down" in the rate of increase of drawdown. When drawdown (water level) is stable, the inflow rates of the various inflow zones are assumed to be steady. By contrast, if DI water injection is begun in the early stages of pumping when drawdown is still increasing, i.e. wvater level is dropping rapidly, the inflow rates of the various inflow zones would increase with time as less wellbore storage is used to maintain a particular pumping rate. The remaining FEC logs (FEC1435, FEC1450, FEC1503, and FEC1516) illustrate the conditions in the borehole during pumping and injection procedures. Fluid was extracted from the borehole at a rate of approximately twelve gpm while DI water was simultaneously injected at the bottom of the borehole at a rate of approximately two gpm, until a relatively steady-state condition existed in the well. Water-bearing intervals in the borehole are identified by changes or "steps" in FEC throughout the FEC logs. The flow rate of these intervals is computed using BORE II and/or Flowcalc software. Every location that the FEC increases in these logs is a zone of inflow.

Similarly, where the logs decrease in FEC indicates a zone of inflow with water lower in FEC than the water in the borehole. A zone exhibiting a decrease in FEC on the injection logs should also decrease at the same depth on the development (pre-DI wvater injection) logs. Please refer to Appendix B for a complete discussion of the BORE II modeling software.

Sensitivity of Transmissivitv to Effective Radius An estimation of transmissivity (t) has be made for all identified water-bearing intervals using an equation after Hvorslev (1951) assuming steady-state radial flow in an unconfined aquifer:

T =YL= qi In 2nAhw krev) where K is the hydraulic conductivity, q; is the interval specific inflow rate calculated using HpLT1 results (or "Delta Flow" from the table which equals "Interval-Specific Flow Rate During Pumping Conditions" minus "Ambient Flow Rate" if any), rw is the borehole radius, r, is the effective pumping radius, Ahw is the observed maximum drawdown and L is the thickness of the zone through which flow occurs. For this example, the data is taken from a test borehole in fractured limestone in Birmingham, Alabama is used. The thickness, or length of the interval is calculated using a combination of both the HpLTNI data and the OBI optical data. L can usually be estimated with a high degree of confidence based on both of those data sets. Qj, or Delta Flow, can also be estimated accurately using code BORE 11 (see appendix B) for the HpLTrI data sets.

Ah, is estimated with a high degree of confidence using Cologs' downhole pressure transducer and a laptop to record water-level data every 10 seconds. Additionally, the borehole radius is confirmed quite readily from the caliper data. For this example, rw equals 0.25 feet, re of 50, 100 and 300 feet are used and the observed maximum drawdown was estimated at 11.64 feet. By applying L and qj from the HpLT^' results under the two pressure conditions, the interval specific transmissivity can be calculated for each identified water-producing interval.

Colog utilizes Hvorslevs' 1951 equation when an observation -well a known distance away with measurable drawdown is not available. Essentially, Hvorslevs' 1951 equation is similar to the prevalent Theis equation minus the observation well drawdown information. In replace of the observation well drawdown data Hvorslevs' equation uses an assumed "effective radius" divided by the borehole radius. One benefit to using Hvorslevs' 1951 equation when observation well data is unavailable is the insensitivity of the equation to the assumed effective radius as this is the only "unknown" variable in the equation. All other variables are known or calculated with a high degree of confidence. Only the effective radius is unproven, or unsupported, but its value can be estimated with some degree of accuracy.

The following example will illustrate the insensitivity of Hvorslevs' 1951 equation in relation to the assumed effective radius of an aquifer. The greatest magnitude of change in this example between r. of 50 feet and r, of 300 feet is 73 feet2 /day transmissivity.

B. Downholc Fluid Sampling COLOG utilizes a 1.5-inch diameter downhole discrete-point fluid sampler manufactured by MLS. After flow zones have been identified by flow logging (HydroPhysicsTM, Heat Pulse or Spinner Flow Meter tests) discrete-point sampling is conducted at selected intervals. The samples are procured just above each identified producing zone to insure complete mixing of the inflowing formation waters fluid moving up the fluid column towards the pump (pump is typically placed inside blank casing). The samples are procured by sending the closed, sealed sampler down to a given depth. By sending a specific voltage down the wireline the sampler ports open up and expose a I or 2 liter barrel to the wellbore fluids. Once the sample barrel is filled, the ports are closed and the sealed sample barrel is brought to the surface for decanting.

Between each procured sample, the sampler tool is thoroughly cleaned with a solution of deionized water and Alconox or Liquinox soap and rinsed with deionized water. The disassembled sampler is then left to air dry or swab-dried before being reassembled.

Using the results from laboratory analysis of each sample procured in the field, the pore water or actual contaminant concentration may be estimated for each sampled inflow point using the mass-balance equation where:

c = qiCi actual IEqi CO Contaminant concentration of procured sample at a given depth as reported by laboratory analysis.

q = Interval specific inflow rate for each hydraulically conductive interval beneath the sample locaf ion as determined by code BORE.

C; actual = Estimated actual contaminant concentration associated with the sampled interval(s).

The accuracy of the results obtained using the Mass-Balance equation is affected by the inputs into the equation and their variability. For example, "error bars" or a range of estimations from the laboratory analysis of the samples or qi estimations would be magnified in their magnitude as a result of the Mass-Balance equation.

BH-118A Logging Results 1.0 HydroPhysicalTm Logging 1.1 Ambient Fluid Electrical Conductivity and Temperature Log: BH-118A At 1043 hours0.0121 days <br />0.29 hours <br />0.00172 weeks <br />3.968615e-4 months <br /> on August 2, 2004, after a calibration check of the fluid electrical conductivity (FEC) and temperature logging tool, the fluid column was logged for FEC and temperature profiles with COLOG's 1.5-inch diameter HpLTmI tool. These logs were performed prior to the installation of any pumping equipment. Please refer to Figure BH-118A:1. The ambient FEC/temperature profiles indicate inflections at approximately 63 feet. These inflections in temperature and FEC correspond well with an identified interval of ambient horizontal flow. The ambient temperature log recorded a gradual increase in temperature with depth to approximately 100 feet, below which occurs a gradual decrease in temperature. The ambient FEC log exhibits a similar trend. An increase in FEC to a depth of approximately 77 feet is observed, below this depth a gradual decrease in FEC is observed. Near the bottom of the ambient FEC log, an increase in FEC is observed. This inflection does not correspond with any interval of flow identified during testing and is most likely the result of sediment or fill in the bottom of the borehole.

1.2 Ambient Flow Characterization: BH-118A On August 2, 2004, an ambient flow characterization was conducted in boring 1311-1 18A. For ambient flow assessment, the fluid column in the borehole was replaced with de-ionized water (DI) and the boring left in an undisturbed state to allow any natural flow to occur. The pump was removed from the boring to insure that water in the pump standpipe would not drain back into the boring. Prior to this period and throughout all HpL'1 1 testing, water levels and flow rates were monitored and recorded digitally every second. Ambient flow evaluation is reported for the period after the water surface returned to near pre-DI water emplacement levels. A series of FEC and temperature logs were then conducted over the duration of testing to identify changes in the fluid column associated with ambient flow. Ambient flow characterization is conducted to evaluate the presence of both vertical and horizontal ambient flow.

On August 2,2004, at 1410 hours0.0163 days <br />0.392 hours <br />0.00233 weeks <br />5.36505e-4 months <br /> (t=0 minutes, elapsed time of test), dilution of the fluid column was complete. Minimal to no DI water was lost to the formation due to the slightly depressed head maintained during DI water emplacement procedures. During the 18.4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> following the emplacement of DI water, multiple logs were conducted. Of these logs, 5 are presented in Figure BH- I 8A:2. The designation of each logging with the FEC tool is indicated in the figure legend by the time of logging (e.g., log FEC1412 was begun at 1412 hours0.0163 days <br />0.392 hours <br />0.00233 weeks <br />5.37266e-4 months <br /> versus a subsequent logging at FEC1448). The progressing of curves to the right in this figure represents changes in FEC over the total logging period. The last four digits of each log ID corresponds to the time at which that particular log was started. Only logs acquired during logging in the downward direction are presented as the design of the FEC/temperature probe allows for the most accurate data to be collected in the downward direction. The logs acquired in the upward logging direction are not representative of downhole conditions and are therefore omitted. These logs illustrate changes at several intervals throughout the upper portion of the borehole. These changes in the FEC profiles with respect to time are associated with ambient horizontal flow occurring within these intervals.

Page I

Formation water migration-caused by horizontal flow within the fluid column is indicated by the increase in FEC over time in Figure BH-1 18A:2 for the intervals at 45.9 to 46.1, 63.9 to 65.0, 113.9 to 114.5, 127.8 to 128.0 and 219.8 to 219.9 feet. Numeric modeling of the reported field

  • data for these intervals suggests horizontal flow is occurring at rates of 0.0008, 0.002, 0.002, 0.003, and 0.001 gpm, respectively. These flow rates are based on the rate of increase of mass at these intervals. Correcting for convergence of flow at the wellbore and factoring the length of the interval, these flow rates equate to a Darcy velocity, or specific discharge of groundwater in the aquifer of 0.61, 0.28, 0.50, 2.27 and 1.51 ft/day, respectively. Please refer to Table BH-1 18A:1 and

SUMMARY

I for a complete summary of the HydroPhysicalT^' logging results. Please refer to Appendix B for a discussion of the methodology and code used to calculate these values. The ambient depth to water at the time of testing was 19.42 ftbgs.

1.3 Flow Characterization During 5 GPM Production Test: BiI-118A Low-rate pumping of wellbore fluids after DI water emplacement was conducted at one pumping rate to establish the inflow locations and evaluate the interval-specific inflow rates. For DI water emplacement, DI water is injected at the bottom of the wellbore while simultaneous extraction pumping is conducted near water surface at the same rate. Water levels and flow rates are monitored and recorded digitally continuously to ensure minimal to no DI water is lost to the formation. This is achieved by maintaining water level at or below the recorded ambient level.

After DI water emplacement is complete low-rate pumping is conducted to stress the aquifer(s) and draw groundwater into the wellbore where it is contrasted by the DI water in the wellbore.

Continuous FEC profiling over time yields the depth and rate of influx of groundwater during pumping. These procedures were conducted at a time-averaged pumping rate of 4.81 gpm.

On August 3, 2004 at 0821 hours0.0095 days <br />0.228 hours <br />0.00136 weeks <br />3.123905e-4 months <br /> (t = 0 minutes elapsed time of testing), pumping was initiated at approximately 5 gpm. Prior to initiating pumping, the ambient depth to water was recorded at 19.31 ftbgs. Time dependent depth to water, pumping totals and flow rate information were recorded and are presented in Figure BH-1 18A:3. Low-rate pumping was maintained at a time-averaged rate of 4.81 gpm until 1746 hours0.0202 days <br />0.485 hours <br />0.00289 weeks <br />6.64353e-4 months <br /> (t = 565 minutes, elapsed time of testing). During this period drawdown was observed to stabilize at approximately 4.8 feet. A maximum drawdown of 4.81 feet was observed. During the period of testing, multiple loggings were conducted. Of these logs, thirteen FEC traces are presented in Figures BH-1 18A:4A and 4B. These logs clearly illustrate specific intervals of dramatic increase in FEC with respect to time. The depth at which the peak value for a given interval occurs is indicative of a water-bearing interval. The data presented in Figures BH-1 18A:4A and 4B suggests the presence of 13 hydraulically conductive intervals, with the dominant water-bearing interval at 29.8 to 30.2 feet. Numerical modeling of the reported field data was performed using code BOREII (Hale and Tsang, 1988, Tsang et.al.

1990, Daughtery and Tsang, 2000). This modeling was performed to estimate the rate of inflow and FEC for each identified hydraulically conductive interval during pumping. The results of the modeling and analysis are presented in Table BH-1 18A:1. In summary, the interval 29.8 to 30.2 feet dominated inflow producing 3.81 gpm, or 79.2 percent of the total inflow during production testing. Please refer to Table BH-1 18A:1 for a complete listing of the depths of water-bearing zones and their interval-specific inflow rates during testing.

At the conclusion of the test, the extraction pump inlet was lowered to approximately 110 feet below ground surface per the request of CH2M Hill. The extraction rate was increased to approximately 30 gpm (max rate) in order to induce more drawdown and evaluate the presence, or lack of, any water-bearing intervals in the lower portion of the wellbore under increased stressed conditions. This increase in extraction rate identified one additional minor flow interval Page 2

at approximately 430 feet. The estimated flow rate of this interval is approximately less than 0.05 gpm, or less than 0.2 percent of the total extraction rate during the increased development pumping.

1.4 Downhole Sampling Eight downhole samples and one wellhead sample were procured from wellbore BH-I 18A on August 3, 2004. Downhole samples were procured from depths of 25.5, 40.3, 53.4, 67.5, 72, 97, 109 and 124.7 feet. The wellhead sample was taken from the discharge outlet of the downhole pump. The downhole pump was set at 28 feet. Downhole sampling was conducted during development pumping at a time-averaged rate of 4.89 gpm after production testing was completed. The laboratory analyses of the procured samples are incorporated with the hydrophysical flow data to obtain actual, or "pore" water, contaminant concentrations for each sampled interval using the mass-balance equation. In summary, the highest concentrations of contaminants were found in the samples taken from 40 and 68 feet. The actual contaminant concentrations of these samples are 13911 and 13,046 pCi/L. Please refer to Table BH-1 18A:2 for a complete listing of sample locations and actual contaminant concentrations. The sample taken at 26 feet did not correspond with any interval of identified flow, therefore, this sample has not been included in Table BH-I 18A:2 The sample locations were identified by on-site interpretation of the FEC/Temperature logs acquired during pumping. Between procurement of samples, the downhole sampler was cleaned with an alconox and DI water solution and rinsed with DI water.

1.5 Estimation of Interval Specific Transmissivity: BII-118A An estimation of transmissivity (T) can be made using an equation after Hvorslev (1951) assuming steady-state radial flow in an unconfined aquifer:

T=KL= qi In(Le) 27TAhw XrwvJ where K is the hydraulic conductivity, qi is the interval specific inflow rate calculated by HpLTNI results, r, is the borehole radius (0.25 fi), r, is the effective pumping radius, Ahab is the observed maximum drawdown (4.81 feet) and L is the thickness of the zone through which flow occurs.

For our calculations, COLOG used r, of 100 feet (assumed). By applying L and qi from the HpLTrI results under the two pressure conditions, the interval specific hydraulic conductivity can be calculated for each identified water producing interval. The calculations made at each identified interval are presented in Table BH-I 18A:1. In summary, the interval at 29.8 to 30.2 feet registered the highest transmissivity at 145 feet2/day.

2.0 Data Summary Processing and interpretation of the HydroPhysicalTM logs in BH-l 18A suggest the presence of 13 producing intervals for this borehole. Numerical modeling of the reported HydroPhysicalT1i field data was performed to estimate the rate of inflow for each identified hydraulically conductive borehole interval during DI injection procedures. The results of these analyses are presented in Page 3

Table BH- 18A:1. These identified producing intervals correlate we'll with water-bearing zones identified during ambient testing. In summary, the interval 29.8 to 30.2 feet dominated inflow during the production test, producing 3.81 gpm, or 79.2 percent of the total flow during the production test.

During ambient testing, boring BH-1 18A exhibited a horizontal flow regime. Five water-bearing zones were identified under ambient conditions exhibiting horizontal flow. No vertical pressure gradient was observed under ambient conditions. The five water-bearing zones at 45.9 to 46.1, 63.9 to 65.0, 113.9 to 114.5, 127.8 to 128.0 and 219.8 to 219.5 feet contributed water to the borehole at estimated flow rates of 0.0008, 0.002, 0.002, 0.003, and 0.001 gpm, respectively.

Correcting for convergence of flow at the wellbore and factoring the length of the interval, these flow rates equate to a Darcy velocity, or specific discharge of groundwater in the aquifer of 0.61, 0.28, 0.50, 2.27 and. 1.51 ft/day, respectively.

The ambient fluid temperature log (Figure BH-1 18A:1) acquired on August 2, 2004 indicates an increase in temperature with depth to approximately 100 feet. Below this depth, the log indicates a decrease in temperature with depth. The ambient FEC profile indicates an increase in fluid conductivity with depth to approximately 77 feet. Below this depth, the log indicates a decrease in.FEC with depth. Both the temperature and FEC log exhibit inflections at approximately 63 feet. This depth corresponds well with an ambient horizontal flow location. The FEC log indicates an increase in FEC near the bottom of the well. As no flow is identified at this depth under ambient or pumping conditions, this inflection is most likely the result of sediment or fill in the bottom of the borehole.

Interval-specific FEC did not differ significantly with the sole exception of the uppermost flow zone at 29.8 - 30.2 feet registering 857 pS/cm.

The 13 interval-specific estimated transmissivities in BH-1 18A ranged from 0.076 to 145 square feet per day with the interval of 29.8 to 30.2 feet registering the highest transmissivity. The 13 interval-specific transmissivity estimates differ significantly with respect to each other, howeveri for the intervals producing the appreciable amounts of flow during testing (the major flow zones) the interval-specific transmissivity estimates do not differ significantly.

Downhole sampling was conducted in wellbore BH-118A during development pumping at a time-averaged rate of 4.89 gpm after production testing was completed. Eight downhole samples and one wellhead sample were procured from wellbore BH-1 18A. The samples procured from 40 and 68 feet contained the highest levels of contaminant concentration.

Fracture inter-connectiveness in the immediate vicinity of a wellbore can be inferred by the similarity, or lack there of, of parameters such as interval-specific transmissivity estimates and interval-specific FEC, along with the presence of pressure differentials within the borehole.

Similar transmissivity and FEC estimates would suggest an inter-connected network of fractures or aquifers in the immediate vicinity of the wellbore. Although a pressure differential present in the wellbore would suggest the driving force for vertical communication is present, in a vertically inter-connected network of fractures the aquifer pressures tend to equilibrate.

The data acquired in BH-1 18A exhibited similar interval-specific transmissivity and similar FEC estimates among the dominant water-bearing zones suggesting an inter-connected network of fractures near the surface. No vertical gradient is observed in the wellbore suggesting the dominant water-bearing intervals are inter-connected thereby negating any pressure differentials.

Page 4

The data suggest the fractures intersecting the wellbore may be inter-connected in the immediate vicinity of the wellbore. Please see Tables BH-I 18A:1 and

BH-119 Logg-ing!Results 1.0 HydroPliysicafm Logging 1.1 Ambient Fluid Electrical Conductivity and Temperature Log: BH-119 At 1049 hours0.0121 days <br />0.291 hours <br />0.00173 weeks <br />3.991445e-4 months <br /> on July 22, 2004, after a calibration check of the fluid electrical conductivity (FEC) and temperature logging tool, the fluid column was logged for FEC and temperature profiles with COLOG's 1.5-inch diameter HpLr tool. These logs were performed prior to the installation of any pumping equipment. Please refer to Figure BH-119:1. The ambient FEC/temperature profiles indicate inflections at approximately 47 feet. These inflections in temperature and FEC correspond well with an identified interval of ambient horizontal flow. The ambient temperature log recorded a gradual increase in temperature with depth to approximately 88 feet, below this depth the log indicates a gradual decrease in temperature to approximately 300 feet. Below this depth the log indicates a gradual increase in temperature with depth. The ambient FEC log is relatively featureless below the inflection at approximately 47 feet.

1.2 Ambient Flow Characterization: BI-1 19 On July 22, 2004, an ambient flow characterization was conducted in boring Bl-l 19. For ambient flow assessment, the fluid column in the borehole was replaced with de-ionized water (DI) and the boring left in an undisturbed state to allow any natural flow to occur. The pump was removed from the boring to insure that water in the pump standpipe would not drain back into the boring. Prior to this period and throughout all HpLTN' testing, water levels and flow rates were monitored and recorded digitally every ten seconds. Ambient flow evaluation is reported for the period after the 'water surface returned to near pre-DI water emplacement levels. A series of FEC and temperature logs were then conducted over the duration of testing to identify changes in the fluid column associated with ambient flow. Ambient flow characterization is conducted to evaluate the presence of both vertical and horizontal ambient flow.

On July 22, 2004, at 1502 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.71511e-4 months <br /> (t=O minutes, elapsed time of test), dilution of the fluid column was complete. Minimal to no DI water was lost to the formation due to the slightly depressed head maintained during DI water emplacement procedures. During the 17.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> following the emplacement of DI water, multiple logs were conducted. Of these logs, 3 are presented in Figure BH-l 19:2. The designation of each logging with the FEC tool is indicated in the figure legend by the time of logging (e.g., FEC1521 versus a subsequent logging at FEC1622), thus the progressing of curves to the right in this figure represents changes in FEC over the total logging period. The last four digits of each log ID corresponds to the time at which that particular log was started. Only logs acquired during logging in the downward direction are presented as the design of the FEC/temperature probe allows for the most accurate data to be collected in the downward direction. The logs acquired in the upward logging direction are not representative of downbole conditions and are therefore omitted. These logs illustrate changes in FEC at several intervals throughout the upper portion of the borehole. These changes in the FEC profiles with respect to time are associated with ambient horizontal flow occurring within these intervals.

Formation water migration caused by horizontal flow within the fluid column is indicated by the increase in FEC over time in Figure BH-1 19:2 for the intervals at 47.3 to 47.4, 85.2 to 88.8, 160.0 to 160.3, 253.0 - 254.5 and 262.2 to 263.8 feet. Numeric modeling of the reported field data for Page 1

these intervals suggests horizontal flow is occurring at rates of 0.003, 0.001, 0.001, 0.0002, and 0.0002 gpm, respectively. These flow rates are based on the rate of increase of mass at these intervals. Correcting for convergence of flow at the wellbore and factoring the length of the interval, these flow rates equate to a Darcy velocity, or specific discharge of groundwater in the aquifer 4.54, 0.04, 0.50, 0.02 and 0.02 ft/day, respectively. Please refer to Table BH-I 19:1 and

SUMMARY

1.3 Flow Characterization During 1.4 GPM Production Test: BH-119 Low-rate pumping of wellbore fluids after DI water emplacement was conducted at one pumping rate to establish the inflow locations and evaluate the interval-specific inflow rates. Low-rate pumping at a given rate after DI water emplacement is conducted when the subject wellbore cannot sustain more than approximately 2-3 gpm yield. For DI water emplacement, DI water is injected at the bottom of the wellbore while simultaneous extraction pumping is conducted near water surface at the same rate. Water levels and flow rates are monitored and recorded digitally continuously to ensure minimal to no DI water is lost to the formation. This is achieved by maintaining water level at or below the recorded ambient level. After DI water emplacement is complete low-rate pumping is conducted to stress the aquifer(s) and draw groundwater into the wellbore where it is contrasted by the DI water in the wellbore. Continuous FEC profiling over time yields the depth and rate of influx of groundwater during pumping. These procedures were conducted at a time-averaged pumping rate of 1.40 gpm.

On July 23, 2004 at 0925 hours0.0107 days <br />0.257 hours <br />0.00153 weeks <br />3.519625e-4 months <br /> (t = 0 minutes elapsed time of testing), pumping was initiated at approximately 1.4 gpm. Prior to initiating pumping, the ambient depth to water was recorded at 18.28 ftbgs. Time dependent depth to water, totals and flow rate information were recorded and are presented in Figure BH-119:3. Low-rate pumping was maintained at a time-averaged rate of 1.40 gpm until 1521 hours0.0176 days <br />0.423 hours <br />0.00251 weeks <br />5.787405e-4 months <br /> (t = 356 minutes, elapsed time of testing). During this period drawdown was observed to stabilize at approximately 20 feet. In the case of a low-yield well such as BH-I 19, drawdown may. take some time to reach equilibrium. While drawdown is stabilizing, wellbore storage contributes to the total extraction rate. The volume of borehole fluid that is removed from the well during extraction pumping is calculated and incorporated in the numerical modeling of the field data. Wellbore storage contributed 0.044 gpm during the late-time testing. A maximum drawdown of 20.75. feet was observed. During the period of testing, multiple loggings were conducted. Of these logs eight FEC traces are presented in Figure BH-119:4. These logs clearly illustrate specific intervals of dramatic increase in FEC with respect to time. The depth at which the peak value for a given interval occurs is indicative of a water-bearing interval. The data presented in Figure BH-119:4 suggests the presence of 18 hydraulically conductive intervals, with the dominant water-bearing interval at 85.2 to 88.8 feet.

Numerical modeling of the reported field data was performed using code BOREII (Hale and Tsang, 1988, Tsang et.al. 1990, Daughtery and Tsang, 2000). This modeling was performed to estimate the rate of inflow and FEC for each identified hydraulically conductive interval during the pumping. The results of the modeling and analysis are presented in Table BH-1 19:1. In summary, the interval of 85.2 to 88.8 feet dominated inflow producing 0.438 gpm, or 32.4 percent of the total inflow during production testing. Please refer to Table BH-119:1 for a complete listing of the depths of water-bearing zones and their interval-specific inflow rate during testing.

1.4 Downholc Sampling Eight downhole samples and one wellhead sample were procured from wellbore BH-1 19 on July 26, 2004. Downhole samples were procured from depths of 44, 70, 82, 143, 156, 254, 298 and 454 feet. Downhole sampling was conducted during development pumping at a time-averaged rate of 1.41 gpm after production testing was completed. The laboratory analyses of the procured samples are incorporated with the hydrophysical flow data to obtain actual, or "pore" water, contaminant concentrations for each sampled interval using the mass-balance equation.

Wellbore BH-I 19 exhibited relatively minor flow rates in the lower portion of the wellbore.

Complete development of flow intervals exhibiting such small flow rates may take days. For this reason, samples collected at 254, 298 and 454 feet do not represent fully developed flow intervals. A ratio of borehole fluid dilution at the time of sampling was calculated by comparing FEC of the developing interval at the time of testing (sampling) and actual the FEC of the interval estimated through numerical modeling or observed in the ambient FEC log. This ratio was applied to the laboratory results to estimate actual contamination levels of the lowermost three sampled intervals. These intervals had not completely developed; therefore, the mixing of these lowermost intervals may be better estimated using laboratory concentrations. As opposed to the standard procedure of sampling above a developed producing zone, these zones were sampled with the sampler intake ports at precisely the depth of the interval due to their lack of development. These samples, along with the subsequent estimation of the dilution factor, may not be representative of actual contaminant concentrations. Because these intervals are not well developed and the mixing of the water in the borehole at these intervals can not be determined, the HNP laboratory results should be considered likely more representative estimates of tritium concentrations at these depths.

In summary the intervals 47.3 to 47.4, 74.4 to 74.5 and 85.2 to 88.8 feet registered the highest pore water concentrations of tritium at 9,148, 18,346 and 10,107 pCiIL, respectively. Please refer to Table BH-1 19:2 for a listing of sample depths and actual contamination concentrations.

The sample locations were identified by on-site interpretation of the FEC/Temperature logs acquired during pumping. Between procurement of samples, the downhole sampler was cleaned with an alconox and DI water solution and rinsed with DI water.

1.5 Estimation of Interval Specific Transmissivity: BH- 19 An estimation of transmissivity (1') can be made using an equation after Hvorslev (1951) assuming steady-state radial flow in an unconfined aquifer:

T=KL= qi n(Le 2zAhw krwl where K is the hydraulic conductivity, qj is the interval specific inflow rate calculated by HpLT' results, r, is the borehole radius (0.25 f1), r, is the effective pumping radius, Ahw, is the observed maximum drawdown (20.75 feet) and L is the thickness of the zone through which flow occurs.

For our calculations, COLOG used r, of 100 feet (assumed). By applying L and qj from the HpLTm results under the two pressure conditions, the interval specific hydraulic conductivity can be calculated for each identified water producing interval. These calculations were made at each Page 3

identified interval and are presented in Table BH-119:1. In summary, the interval 85.2 to 88.8 feet registered the highest transmissivity at 3.86 feee/day.

2.0 Data Summary Processing and interpretation of the HydroPhysicalT^' logs in BH-l 19 suggest the presence of 18 producing intervals for this borehole. Numerical modeling of the reported HydroPhysicalT1I field data was performed using the computer program BOREII. These analyses were performed to estimate the rate of inflow for each identified hydraulically conductive borehole interval during Di injection procedures. The results of these analyses are presented in Table BH-l 19:1. These identified producing intervals correlate well with water-bearing zones identified during ambient testing. In summary, the interval 85.2 to 88.8 feet dominated inflow during the production test, producing 0.438 gpm, or 32.4 percent of the total flow during the production test.

During ambient testing, boring BH-1 19 exhibited a horizontal flow regime. Five water-bearing zones were identified under ambient conditions exhibiting horizontal flow. No vertical pressure gradient was observed under ambient conditions. The five water-bearing zones at 47.3 to 47.4, 85.2 to 88.8, 160.0 to 160.3, 241.2 to 241.4 and 262.2 to 263.8 feet contributed water to the borehole at estimated flow rates of 0.003, 0.001, 0.001, 0.0002, and 0.0002 gpm, respectively.

Correcting for convergence of flow at the wellbore and factoring the length of the interval, these flow rates equate to a Darcy velocity, or specific discharge of groundwater in the aquifer of 4.54, 0.04, 0.50, 0.02 and 0.02 ft/day, respectively.

The ambient fluid temperature log (Figure BH-119:1) acquired on July 22, 2004 indicates an increase in temperature with depth to approximately 88 feet. Below this depth the log indicates a decrease in temperature with depth to approximately 300 feet. Below this depth the temperature log indicates an increase in temperature with depth. Both the temperature and FEC log exhibit inflections at approximately 47 feet. This depth corresponds well with an ambient horizontal flow location. The ambient FEC profile is relatively featureless with the exception of the infection at approximately 47 feet.

The 18 interval-sp~ecific estimated transmissivities in BH-I 19 ranged from 0.003 to 3.86 square feet per day with the interval of 85.2 to 88.8 feet registering the highest transmissivity. The 18 interval-specific transmissivity estimates differ significantly with respect to each other, however, regarding just the dominant water producing zones interval-specific transmissivity did not differ significantly.

Downhole sampling was conducted in wellbore BH-1 19 on July 26, 2004 at a time-averaged rate of 1.41 gpm after production testing was completed. Eight downhole samples and one wellhead sample were procured from wellbore BH-1 19. The samples procured from 44 and 82 feet contained the highest levels of contaminant concentration.

Fracture inter-connectiveness in the immediate vicinity of a wellbore can be inferred by the similarity, or lack there of, of parameters such as interval-specific transmissivity estimates and interval-specific FEC, along with the presence of pressure differentials within the borehole.

Similar transmissivity and FEC estimates would suggest an inter-connected network of fractures or aquifers in the immediate vicinity of the wellbore. Although a pressure differential present in the wellbore would suggest the driving force for vertical communication is present, in a vertically inter-connected network of fractures the aquifer pressures tend to equilibrate.

Page 4

The data acquired in BH-119 exhibited similar interval-specific transmissivity estimates among dominant water producing intervals and similar FEC estimates. No vertical gradient is observed in the wellbore. The data suggest the fractures intersecting the wellbore may be inter-connected in the immediate vicinity of the wellbore. Please see Tables BH-l 19:1 and

BH-120 Logging Results 1.0 HydroPhysicalT( Logging 1.1 Ambient Fluid Electrical Conductivity and Temperature Log: BH-120 At 1059 hours0.0123 days <br />0.294 hours <br />0.00175 weeks <br />4.029495e-4 months <br /> on August 4, 2004, after a calibration check of the fluid electrical conductivity (FEC) and temperature logging tool, the fluid column was logged for FEC and temperature profiles with COLOG's 1.5-inch diameter HpLTb' tool. These logs were performed prior to the installation of any pumping equipment. Please refer to Figure BH-120:1. The ambient FEC profile indicates an inflection at approximately 142 feet. This inflection in FEC corresponds well with an identified interval of ambient horizontal flow. The remainder of the FEC log was relatively featureless. The ambient temperature log recorded a gradual decrease in temperature with depth to approximately 313 feet, below this depth the log indicates a gradual increase in temperature to approximately wellbore TD (550.9 ft).

1.2 Ambient Flow Characterization: BH-120 On August 4, 2004, an ambient flow characterization was conducted in boring BH-120. For ambient flow assessment, the fluid column in the borehole was replaced with de-ionized water (DI) and the boring left in an undisturbed state to allow any natural flow to occur. The pump was removed from the boring to insure that water in the pump standpipe would not drain back into the boring. Prior to this period and throughout all HpLTNI testing, water levels and flow rates were monitored and recorded digitally every ten seconds. Ambient flow evaluation is reported for the period after the water surface returned to near pre-DI water emplacement levels. A series of FEC and temperature logs were then conducted over the duration of testing to identify changes in the fluid column associated with ambient flow. Ambient flow characterization is conducted to evaluate the presence of both vertical and horizontal ambient flow.

On August 4, 2004, at 1427 hours0.0165 days <br />0.396 hours <br />0.00236 weeks <br />5.429735e-4 months <br /> (t=0 minutes, elapsed time of test), dilution of the fluid column was complete. Minimal to no DI water was lost to the formation due to the slightly depressed head maintained during DI water emplacement procedures. During the 17.6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> following the emplacement of DI water, multiple logs were conducted. Of these logs, 4 are presented in Figure BH-120:2. The designation of each logging with the FEC tool is indicated in the figure legend by the time of logging (e.g., FEC1443 versus a subsequent logging at FEC1558), thus the progressing of curves to the right in this figure represents changes in FEC over the total logging period. The last four digits of each log ID corresponds to the time at which that particular log was started. Only logs acquired during logging in the downward direction are presented as the design of the FEC/temperature probe allows for the most accurate data to be collected in the downward direction. The logs acquired in the upward logging direction are not representative of downhole conditions and are therefore omitted. These logs illustrate changes at several intervals throughout the upper portion of the borehole. These changes in the FEC profiles with respect to time are associated with ambient horizontal flow occurring within these intervals.

Formation water migration caused by horizontal flow within the fluid column is indicated by the increase in FEC over time in Figure BH-120:2 for the intervals at 105.6 to 106.0, 153.2 to 153.3 and 211.0 to 211.3 feet. Numeric modeling of the reported field data for these intervals suggests horizontal flow is occurring at rates of 0.004, 0.008 and 0.002 gpm, respectively. These flow Page 1

rates are based on the rate of increase of mass at these intervals. Correcting for convergence of flow at the wellbore and factoring the length of the interval, these flow rates equate to a Darcy velocity, or specific discharge of groundwater in the aquifer 1.51, 12.1 and 1.01 ft/day, respectively. Please refer to Table BH-120:1 and

SUMMARY

1 for a complete summary of the HydroPhysicalT"I logging results. Please refer to Appendix B for a discussion of the methodology and code used to calculate these values. The ambient depth to water at the time of testing was 18.23 flbgs.

1.3 Flow Characterization During 1.9 GPM Production Test: BII-120 Low-rate pumping of wellbore fluids after DI water emplacement was conducted at one pumping rate to establish the inflow locations and evaluate the interval-specific inflow rates. Low-rate pumping at a given rate after DI water emplacement is conducted when the subject wellbore cannot sustain more than approximately 2-3 gpm yield. For DI water emplacement, DI water is injected at the bottom of the wellbore while simultaneous extraction pumping is conducted near water surface at the same rate. Water levels and flow rates are monitored and recorded digitally continuously to ensure minimal to no DI water is lost to the formation. This is achieved by maintaining water level at or below the recorded ambient level. After DI water emplacement is complete low-rate pumping is conducted to stress the aquifer(s) and draw groundwater into the wellbore where it is contrasted by the DI water in the wellbore. Continuous FEC profiling over time yields the depth and rate of influx of groundwater during pumping. These procedures were conducted at a time-averaged pumping rate of 1.85 gpm.

On August 5, 2004 at 0826 hours0.00956 days <br />0.229 hours <br />0.00137 weeks <br />3.14293e-4 months <br /> (t=0 minutes elapsed time of testing), pumping was initiated at approximately 1.9 gpm. Prior to initiating pumping, the ambient depth to water was recorded at 17.96 flbgs. Time dependent depth to water, totals and flow rate information were recorded and are presented in Figure BH-120:3. Low-rate pumping was maintained at a time-averaged rate of 1.85 gpm until 1612 hours0.0187 days <br />0.448 hours <br />0.00267 weeks <br />6.13366e-4 months <br /> (t = 466 minutes, elapsed time of testing). During this period drawdown was observed to stabilize at approximately 16.9 feet. In the case of a low-yield well such as BH-120, drawdown may take some time to reach equilibrium. While drawdown is stabilizing, wellbore storage contributes to the total extraction rate. The volume of borehole fluid that is removed from the well during extraction pumping is calculated and included in the numerical modeling of the field data. A maximum drawdown of 16.90 feet was observed.

During the period of testing, multiple loggings were conducted. Of these logs twelve FEC traces are presented in Figure 13H-120:4. These logs clearly illustrate specific intervals of dramatic increase in FEC with respect to time. The depth at which the peak value for a given interval occurs is indicative of a water-bearing interval. The data presented in Figure BH-120:4 suggests the presence of11 hydraulically conductive intervals, with the dominant water-bearing interval at 105.6 to 106.0 feet. Numerical modeling of the reported field data was performed using code BORETI (Hale and Tsang, 1988, Tsang et.al. 1990, Daughtery and Tsang, 2000). This modeling was performed to estimate the rate of inflow and FEC for each identified hydraulically conductive interval during the pumping. The results of the modeling and analysis are presented in TableBH-120:1. In summary, the interval of 105.6 to 106.0 feet dominated inflow producing 0.778 gpm, or 41 percent of the total inflow during production testing. Please refer to Table BH-120:1 for a complete listing of the depths of water-bearing zones and their interval-specific inflow rate during testing.

1.4 Downhole Sampling Page 2

Seven downhole samples and one wellhead sample were procured from wellbore BH-120 on August 5, 2004. Downhole samples were procured from depths 77, 85, 100, 124, 136, 208 and 231 feet. The wellhead sample was taken from the discharge outlet of the downhole pump. The downhole pump was set at 35 feet. Dowvnhole sampling was conducted during development pumping at a time-averaged rate of 1.80 gpm after production testing was completed. The laboratory analyses of the procured samples are incorporated with the hydrophysical flow data to obtain actual, or "pore" water, contaminant concentrations for each sampled interval using the mass-balance equation. In summary, the interval 83.5 to 83.6 registered the highest concentration of tritium at 15,413 pCi/L. Please refer to Table BH-120:2 for a complete listing of sample locations and actual contaminant concentrations. The sample taken at 35 feet (wellhead) did not correspond with any interval of identified flow, therefore, this sample has not been included in Table BH-120:2 The sample locations were identified by on-site interpretation of the FEC/Temperature logs acquired during pumping. Between procurement of samples, the downhole sampler was cleaned with an alconox and DI water solution and rinsed with DI water.

1.5 Estimation of Interval Specific Transmissivity: BH-120 An estimation of transmissivity (1) can be made using an equation after Hvorslev (1951) assuming steady-state radial flow in an unconfined aquifer:

T=KL= qi In (re\

where K is the hydraulic conductivity, qi is the interval specific inflow rate calculated by HpLT^'

results, r. is the borehole radius (0.25 ft), r. is the effective pumping radius , Ah,, is the observed maximum drawdown (16.90 feet) and L is the thickness of the zone through which flow occurs.

For our calculations, COLOG used r. of 100 feet (assumed). By applying L and qi from the HpLTm results under the two pressure conditions, the interval specific hydraulic conductivity can be calculated for each identified water producing interval. These calculations were made at each identified interval and are presented in Table BH-120:1. In summary, the interval 105.6 to 106.0 feet registered the highest transmissivity at 8.39 feee/day.

2.0 Data Summarv Processing and interpretation of the HydroPhysicalTht logs in BH-1 20 suggest the presence of 11 producing intervals for this borehole. Numerical modeling of the reported HydroPhysicalTm field data was performed using the computer program BOREII. These analyses were performed to estimate the rate of inflow for each identified hydraulically conductive borehole interval during DI injection procedures. The results of these analyses are presented in Table BH-120:1. These identified producing intervals correlate well with water-bearing zones identified during ambient testing. In summary, the interval 105.6 to 106.0 feet dominated inflow during the production test, producing 0.778 gpm, or 41 percent of the total flow during the production test.

During ambient testing, boring BH-120 exhibited a horizontal flow regime. Four water-bearing zones were identified under ambient conditions exhibiting horizontal flow. No vertical pressure Page 3

gradient was observed under ambient conditions. The four water-bearing zones at 105.6 to 106.0, 153.2 to 153.3 and 211.0 to 211.3 feet contributed water to the borehole at estimated flow rates of 0.004, 0.008 and 0.002 gpm, respectively. Correcting for convergence of flow at the wellbore and factoring the length of the interval, these flow rates equate to a Darcy velocity, or specific discharge of groundwater in the aquifer of aquifer 1.51, 12.1 and 1.01 ftl/day, respectively.

The ambient fluid temperature log (Figure BH-120:1) acquired on August 4, 2004 indicates a decrease in temperature with depth to approximately 313 feet. Below this depth the log indicates an increase in temperature with depth to TD (550.9 ft). The ambient FEC profile exhibits an inflection at approximately 142 feet. This depth corresponds well with an identified ambient horizontal flow location. The ambient FEC profile is relatively featureless with the exception of the infection at approximately 142 feet.

The 11 interval-specific estimated transmissivities in BH-120 ranged from 0.043 to 8.93 square feet per day with the interval of 105.6 to 106.0 feet registering the highest transmissivity. Among dominant water producing intervals the interval-specific transmissivity estimates do not differ significantly with respect to each other.

Downhole sampling was conducted in wellbore BH-120 during development pumping at a time-averaged rate of 1.80 gpm after production testing was completed. Seven downhole samples and one wellhead sample were procured from wellbore BH-120. The sample procured from 77 feet contained the highest levels of contaminant concentration.

Fracture inter-connectiveness in the immediate vicinity of a wellbore can be inferred by the similarity, or lack there of, of parameters such as interval-specific transmissivity estimates and interval-specific FEC, along with the presence of pressure differentials within the borehole.

Similar transmissivity and FEC estimates would suggest an inter-connected network of fractures or aquifers in the immediate vicinity of the wellbore. Although a pressure differential present in the wellbore would suggest the driving force for vertical communication is present, in a vertically inter-connected network of fractures the aquifer pressures tend to equilibrate.

The data acquired in BH-120 exhibited similar interval-specific transmissivity estimates among dominant water producing intervals and somewhat similar FEC estimates suggesting an inter-connected network of fractures in the immediate vicinity of the wellbore. No vertical gradient is observed in the wellbore. The data suggest the fractures intersecting the wellbore may be vertically interconnected in the immediate vicinity of the wellbore.

BH-121A Logging Results 1.0 HydroPhysicapA Logging 1.1 Ambient Fluid Electrical Conductivity and Temperaturc Log: BH-121A At 0817 hours0.00946 days <br />0.227 hours <br />0.00135 weeks <br />3.108685e-4 months <br /> on July 28, 2004, after a calibration check of the fluid electrical conductivity (FEC) and temperature logging tool, the fluid column was logged for FEC and temperature profiles with COLOG's 1.5-inch diameter HpLT tool. These logs were performed prior to the installation of any pumping equipment. Please refer to Figure BH-121A:I. The ambient FEC profile indicates notable inflections at approximately 98, 126, 160, 277, 217 and 455 feet. The inflection in FEC at approximately 98 feet corresponds with the base of casing. The inflection in FEC at approximately 277 feet corresponds relatively well with an interval of identified ambient horizontal flow. The inflection at approximately 455 feet corresponds relatively well with a water bearing zone identified during development pumping. The FEC log indicated a general increase in FEC with depth. The ambient temperature log recorded notable inflections at approximately 98, 277 and 405 feet. The infection at approximately 98 feet corresponds relatively well with the base of casing. The inflection at approximately 277 feet corresponds relatively well with an interval of identified ambient horizontal flow. The temperature log indicates a general decrease in temperature with depth to approximately 277 feet. Below this depth the temperature log indicates a general increase in temperature with depth, with the exception of the infection at approximately 405 feet.

1.2 Ambient Flow Characterization: BH-121A On July 28, 2004, an ambient flow characterization was conducted in boring BH-121A. For ambient flow assessment, the fluid column in the borehole was replaced with de-ionized water (DI) and the boring left in an undisturbed state to allow any natural flow to occur. The pump was removed from the boring to insure that water in the pump standpipe would not drain back into the boring. Prior to this period and throughout all HpLT ^' testing, water levels and flow rates were monitored and recorded digitally every ten seconds. Ambient flow evaluation is reported for the period after the water surface returned to near pre-DI water emplacement levels. A series of FEC and temperature logs were then conducted over the duration of testing to identify changes in the fluid column associated with ambient flow. Ambient flow characterization is conducted to evaluate the presence of both vertical and horizontal ambient flow.

On July 28, 2004, at 1733 hours0.0201 days <br />0.481 hours <br />0.00287 weeks <br />6.594065e-4 months <br /> (t=0 minutes, elapsed time of test), dilution of the fluid column was complete. Minimal to no DI water was lost to the formation due to the slightly depressed head maintained during DI water emplacement procedures. During the 15.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> following the emplacement of DI water, multiple logs were conducted. Of these logs, 5 are presented in Figure BH-121A:2. The designation of each logging with the FEC tool is indicated in the figure legend by the time of logging (e.g., FEC1736 versus a subsequent logging at FEC1803), thus the progressing of curves to the right in this figure represents changes in FEC over the total logging period. The last four digits of each log ID corresponds to the time at which that particular log was started. Only logs acquired during logging in the downward direction are presented as the design of the FEC/temperature probe allows for the most accurate data to be collected in the downward direction. The logs acquired in the upward logging direction are not representative of downhole conditions and are therefore omitted. These logs illustrate changes at several intervals Page I

throughout the upper portion of the borehole. These changes in the FEC profiles with respect to time are associated with ambient horizontal flow occurring within these intervals.

Formation water migration caused by-horizontal flow within the fluid column is indicated by the increase in FEC over time in Figure BH-121A:2 for the intervals at 165.9 to 166.8,278.0 to 278.8 and 460.7 to 465.1 feet. Numeric modeling of the reported field data for these intervals suggests that horizontal flow is occurring at rates of 0.012, 0.0008 and 0.0004 gpm, respectively. These flow rates are based on the rate of increase of mass at these intervals. Correcting for convergence of flow at the wellbore and factoring the length of the interval, these flow rates equate to a Darcy velocity, or specific discharge of groundwater in the aquifer 2.02, 0.15 and 0.01 ft/day, respectively. Please refer to Table BH-121A:l and

SUMMARY

l for a complete summary of the HydroPhysicalT1i logging results. Please refer to Appendix B for a discussion of the methodology and code used to calculate these values. The ambient depth to water at the time of testing was 17.19 ftbgs.

1.3 Flow Characterization During 7 GPM Production Test: BII-121A Low-rate pumping of wellbore fluids after Dl water emplacement was conducted at one pumping rate to establish the inflow locations and evaluate the interval-specific inflow rates. Water levels and flow rates are monitored and recorded digitally continuously to ensure minimal to no DI water is lost to the formation. This is achieved by maintaining water level at or below the recorded ambient level. After DI water emplacement is complete low-rate pumping is conducted to stress the aquifer(s) and draw groundwater into the wellbore where it is contrasted by the DI water in the wellbore. Continuous FEC profiling over time yields the depth and rate of influx of groundwater during pumping. These procedures were conducted at a time-averaged pumping rate of 6.69 gpm.

On July 29, 2004 at 1047 hours0.0121 days <br />0.291 hours <br />0.00173 weeks <br />3.983835e-4 months <br /> (t = 0 minutes elapsed time of testing), pumping was initiated at approximately 7 gpm. Before initiating pumping, the ambient depth to water was recorded at 17.35 ftbgs. Time dependent depth to water, totals and flow rate information were recorded and are presented in Figure BH-121A:3. Low-rate pumping was maintained at a time-averaged rate of 6.69 gpm until 1557 hours0.018 days <br />0.433 hours <br />0.00257 weeks <br />5.924385e-4 months <br /> (t = 310 minutes, elapsed time of testing). During this period drawdown was observed to stabilize at approximately 37 feet. During development pumping drawdown may take some time to reach equilibrium. While drawdown is stabilizing, wellbore storage contributes to the total extraction rate. The volume of borehole fluid that is removed from the well during extraction pumping is calculated and included in the numerical modeling of the field data. A maximum drawdown of 37.3 feet was observed. During the period of testing, multiple loggings were conducted. Of these logs eight FEC traces are presented in Figure BH-121A:4. These logs clearly illustrate specific intervals of dramatic increase in FEC with respect to time. The depth at which the peak value for a given interval occurs is indicative of a water-bearing interval. The data presented in Figure BH-121A:4 suggests the presence of 13 hydraulically conductive intervals, with the dominant water-bearing interval at 165.9 to 166.8 feet. Numerical modeling of the reported field data was performed using code BOREII (Hale and Tsang, 1988, Tsang et.al. 1990, Daughtery and Tsang, 2000). This modeling was performed to estimate the rate of inflow and FEC for each identified hydraulically conductive interval during the pumping. The results of the modeling and analysis are presented in Table BH-121A:l. In summary, the interval of 165.9 to 166.8 feet dominated inflow producing 6.26 gpm, or 93.6 percent of the total inflow during production testing. Please refer to Table BH-121A:1 for a complete listing of the depths of water-bearing zones and their interval-specific inflow rate during testing.

1.4 Downhole Sampling Eight downhole samples were procured from wellbore BH-121A.on July 30, 2004. Downhole samples were procured from depths 83, 144, 163, 173, 279, 309, 326 and 464 feet. Downhole sampling was conducted while wellbore BH-121A was being developed at a time-averaged rate of 6.75 gpm. The laboratory analyses of the procured saniples. are incorporated with the hydrophysical flow data to obtain actual, or "pore" water, contaminant concentrations for each sampled interval using the mass-balance equation. In summary, the intervals 165.9 to 166.8 and 177.6 to 177.7 feet registered the highest concentrations of tritium at 7,322 and 8,645 pCi/L, respectively. It is worth noting that the sample procured at 144 feet registering 6,250 pCi/L tritium and the resulting pore water tritium estimation using the Mass-Balance equation of "No Detect" (ND). This is because the sample just below 144 feet procured at 163 feet contained 7,230 pCi/L of tritium with 6.47 gpm (aggregate flow below 163 feet) of flow associated with this sample, which comprises approximately 94 percent of the flow measured in the borehole. The sample procured at 144 feet had only an additional 0.18 gpm of flow associated with it. In other words, the difference in observed concentrations between the sample at 163 feet and 144 feet, as far as estimations made using the Mass-Balance equation are concerned, is solely the result of the introduction of a certain concentration of tritium into the borehole at 0.18 gpm, meaning the water coming into the borehole must be relatively low in tritium compared to the borehole fluids and steady-state conditions are present at and below this depth, hence the ND. Please refer to Table BH-121A:2 for a complete listing of sample locations and actual contaminant concentrations. The sample taken at 83 feet did not correspond with any interval of identified flow, therefore, this sample has not been included in Table BH-121A:2 The sample locations were identified by on-site interpretation of the FEC/Temperature logs acquired during pumping. Between procurement of samples, the downhole sampler was cleaned with an alconox and DI water solution and rinsed with DI water.

1.5 Estimation of Interval Specific Transmissivity: B11-121A An estimation of transmissivity (T) can be made using an equation after Hvorslev (1951) assuming steady-state radial flow in an unconfined aquifer:

T= L= /re T =L =2irAhw inrk v) where K is the hydraulic conductivity, qi is the interval specific inflow rate calculated by HpLT'l results, r, is the borehole radius (0.25 fi), r. is the effective pumping radius, Ahb is the observed maximum drawdown (37.3 feet) and L is the thickness of the zone through which flow occurs.

For our calculations, COLOG used r, of 100 feet (assumed). By applying L and qi from the HpLTNI results under the two pressure conditions, the interval specific hydraulic conductivity can be calculated for each identified water producing interval. These calculations were made at each identified interval and are presented in Table BH-121A:1. In summary, the interval 165.9 to 166.8 feet registered the highest transmissivity at 30.7 feee/day.

2.0 Data Summary Page 3

Processing and interpretation of the HydroPhysicalT^' logs in BH-121A suggest the presence of 13 producing intervals for this borehole. Numerical modeling of the reported HydroPhysicalTM field data was performed using the computer program BOREII. These analyses were performed to estimate the rate of inflow for each identified hydraulically conductive borehole interval during DI injection procedures. The results of these analyses are presented in Table BH-121A:1. These identified producing intervals correlate well with water-bearing zones identified during ambient testing. In summary, the interval 165.9 to 166.8 feet dominated inflow during the production test, producing 6.26 gpm, or 93.6 percent of the total flow during the production test.

During ambient testing, boring BH-121A exhibited a horizontal flow regime. Three water-bearing zones were identified under ambient conditions exhibiting horizontal flow. No vertical pressure gradient was observed under ambient conditions. The three water-bearing zones at 165.9 to 166.8, 278.0 to 278.8 and 467.9 to 469.5 feet contributed water to the borehole at estimated flow rates of 0.012, 0.0008 and 0.0004 gpm, respectively. Correcting for convergence of flow at the wellbore and factoring the length of the interval, these flow rates equate to a Darcy velocity, or specific discharge of groundwater in the 2.02, 0.15 and 0.01 ft/day, respectively.

The ambient fluid temperature log (Figure BH-121A:l) acquired on July 28, 2004 indicates a general decrease in temperature with depth to approximately 277 feet. At approximately 277 feet there is an inflection in temperature that corresponds well with an identified horizontal flow interval. Below this depth the log indicates a general increase in temperature with depth. The ambient FEC profile exhibits a general increase in FEC with depth. Numerous inflections can be observed in the log. The infection in FEC at approximately 277 feet corresponds well with an interval of identified horizontal ambient flow.

The 13 interval-specific estimated transmissivities in BH-121A ranged from 0.004 to 30.7 square feet per day with the interval of 165.9 to 166.8 feet registering the highest transmissivity. The 13 interval-specific transmissivity estimates do not differ significantly with respect to each other with the sole exception of the dominant producing zone at 165.9 to 166.8 feet.

Downhole sampling was conducted in wellbore BH-121A during development pumping at a time-averaged rate of 6.75 gpm after production testing was completed. Eight downhole samples were procured from wellbore BH-121A. In summary, the intervals 165.9 to 166.8 and 177.6 to 177.7 feet registered the highest concentrations of tritium at 7,322 and 8,645 pCi/L, respectively.

Fracture inter-connectiveness in the immediate vicinity of a wellbore can be inferred by the similarity, or lack there of, of parameters such as interval-specific transmissivity estimates and interval-specific FEC, along with the presence of pressure differentials within the borehole.

Similar transmissivity and FEC estimates would suggest an inter-connected network of fractures or aquifers in the immediate vicinity of the wellbore. Although a pressure differential present in the wellbore would suggest the driving force for vertical communication is present, in a vertically inter-connected network of fractures the aquifer pressures tend to equilibrate.

The data acquired in BH-121A exhibited similar interval-specific transmissivity and similar FEC estimates suggesting an inter-connected network of fractures in the immediate vicinity of the wellbore. No vertical gradient is observed in the wellbore. The data suggest the fractures intersecting the wellbore may be inter-connected in the immediate vicinity of the wellbore.

1. Purpose Application of the HydroPhysicalTM (HpL m) logging method to analyze and determine:
  • The location of hydraulically conductive intervals within a wellbore
  • The interval specific rate of inflow during well production, in conjunction with the drawdown data, can be used to estimate interval specific hydraulic conductivity or transmissivity

. Ambient (non-pumping) flow conditions (inflow and outflow rates, and locations)

The hydrochemistry (fluid electrical conductivity (FEC) and temperature) of the associated formation waters In addition, when downhole, discrete point fluid sampling is coupled with the HydroPhysicalTm Logging technique, analysis of the actual contaminant concentrations associated with each identified conductive interval is accomplished for any aqueous phase contaminant.

2.

3. Procedures 1.) Review well construction details and complete general well information sheet.

The HydroPhysicalT^' logging technique involves dilution of the wellbore fluids with DI water and profiling of the wellbore dynamics using a lHydroPhysicalTM logging tool.

Significant aberrations or reductions in the borehole diameter should be identified as the downhole equipment can become lodged in the borehole. Additionally, application of the technique requires certain wellbore conditions:

  • In open bedrock boreholes, casing must be installed through the overburden and grouted at the rock/alluvium interface to inhibit water leakage into the borehole from the saturated alluvium. For cased boreholes, the well should be fully cased and gravel packed with single or multiple screened intervals;
  • The diameter of the borehole must be approximately 4 inches or greater for application with the slim-tool (1.5-inch o.d.). Two inch i.d. boreholes may be tested using the slug test approach described in Section 5.
  • For newly drilled wells, cuttings and drill fluids must be removed from the affected fractures by standard well development procedures.

2.) Review and record additional wellbore construction/site details and fill out the general well information form which includes the following information:

  • Ambient depth-to-water
  • Depth of casing
  • Total depth of well
  • Lithology (if available)

Estimated well yield and any available drawdown data

  • Type and concentration of contamination 3.) Prepare the deionized (DI) water. Consult with DI water tank firm for assistance if necessary. If DI water has not been transported to the site, surface or groundwater may be used if it is of suitable quality Generally source water containing less than 1000 micro Siemens per centimeter (piSfcm) and less then 200 ppb VOCs will not significantly affect the deionizing units, but this should be confirmed with DI water firm. If the groundwater from the well under construction cannot be used for DI water generation, then DI water must be transported to the site and containerized at the wellhead.

X 2004, COLOG

Depending on the amount of HydroPhysicalTM testing to be performed (ambient and/or during production) the typical volume of DI water required for each borehole is approximately three times the volume of the standing column of formation water in the wellbore per type of HlydroPhysicalTM characterization.

If preparation takes place on site, pump the source water through a pre-filter, to the deionizing units, and into the storage tanks.

Monitor the FEC of the DI water in-line to verify homogeneity; the target value is 5 to 25 pIS/cm.

4.) Calibrate the HydroPhysicalTMt logging tool using standard solutions prepared and certified by a qualified chemical supply manufacturer. Fill out tool calibration form following the steps defined in the software program, "tools" under the directory, calibration. Also use a separate field temperature / FEC / p1I meter to support calibration data. Record the results of the tool calibrations, specifically noting any problems on the tool calibration form. Also record the certification number of the standard solutions.

5.) Set datum on the depth encoder with the FEC sensor on the tool as 0 depth at the top of casing. If inadequate space is available at the wellhead, measure 10 feet from the FEC sensor up the cable (using measuring tape) and reference with a wrap of electrical tape. Lower the tool down the hole to the point where the tape equals the elevation at the top of the casing and reference that as 10 feet depth on the depth encoder.

6.) Place the top of the tool approximately 3 feet below the free-water surface to allow it to achieve thermal equilibrium. Monitor the temperature output until thermal stabilization is observed at approximately + .02 'C.

7.) After thermal stabilization of the logging tool is observed, log the ambient conditions of the wellbore (temperature and FEC). Fill out the water quality log form.

During the logging run, the data are plotted in real time in log format on the computer screen and, the data string is simultaneously recorded on the hard drive.

Log the ambient fluid conditions in both directions (i.e. record down and up). The ideal logging speed is 5 feet per minute (fpm). For deeper wells the logging speed can be adjusted higher, but the fpm should not exceed 20.

At completion of the ambient log, place the tool approximately 10 feet below the free water surface. The tool will remain there during equipment set up as long as borehole conditions permit. Establish and record ambient depth to water using top of protective casing as datum.

8.) Attach back pressure regulator or orifice, if used, and weighted boot, to end of emplacement line and secure. Insure that the injection line is of adequate length to reach the bottom of the wellbore.

© 2004, COLOG

9.) Lower the flexible emplacement line to the bottom of the well allowing one foot of clearance from the well bottom to the outlet of the injection line.

10.) Lower tool about 10 feet below the water surface. The tool will be stationed beneath the submersible pump during non-logging times.

11.) Lower submersible pump in the well to a depth just above the logging tool.

Record approximate depth of the pump location.

12.) Record all initial readings of gauges at elapsed time 0.0 minutes. Fill out well testing data form.

13.) Mark hoses with a round of electrical tape for reference. In addition, establish datum for tool depth to the nearest foot and mark on wire with wrap of tape. Reset datum on optical encoder for this depth.

14.) When ambient flow characterization is to be conducted, it should be done now, before disturbing the aquifer (i.e. by pumping). Fill out ambient flow characterization (AFC) form. Skip to Section 17 for procedures.

15.) After AFC, if performed, conduct a controlled, short term well production test (pump test) to characterize the overall hydraulics of the wellbore (drawdown at given pumping rate provides total well transmissivity or yield) and to make an initial assessment of formation water hydrochemistry. Begin pumping at a total extraction flow rate appropriate for wellbore under investigation (see Section 4 Special Notes). During this period, record elapsed time of pumping, depth to water, total gallons extracted, and extraction flow rate at approximately one minute intervals.

During extraction, log the fluid column continuously until at least three wellbore volumes have been extracted from the wellbore, or a stabilized 'water level elevation is obtained.

Review fluid logging results to verify that, true formation water is present within the affected borehole interval and that the vertical distribution of water quality parameters within this interval is stable.

16.) Review data obtained during the pumping test to determine DI water emplacement and pumping/logging procedures. Extraction procedures for detection and characterization of hydraulically conductive intervals and the formation water hydrochemistry are determined based on the pumping test information. The emplacement, testing and pumping procedures will differ depending upon well yield and determined lengths of intervals of interest. In wellbore situations where intervals of interest are small (less than 30 feet) and hydraulic characteristics observed during borehole advancement and preliminary hydraulic testing indicate hydraulically conductive intervals with extremely low flow rates (i.e. <0.10 gpm/foot of drawdown), a slug testing procedure can be employed. In wellbore cases where the preliminary C 2004, COLOG

hydraulic testing indicates low to moderate total yield (i.e. 0.10 < Q < 4 gpm/foot of drawdown), constant low flow rate pumping after DI water emplacement procedures can be employed. In wellbore situations where intervals of interest are large, and high total yield (i.e. > 4 gpm/foot of drawdown) is observed, constant pumping during DI water injection procedures will be employed.

17.) When the fluid column is to be replaced with DI water, (vertical flow characterization, slug testing, logging during pumping after DI water emplacement) the following emplacement procedures akply:

Pump the DI water to the bottom of the wellbore using the surface pump and the injection riser. Simultaneously use the submersible pump to maintain a stable, elevated total head by extracting groundwater from near the free-water surface. When groundwater from the subject well is used for DI water generation, generate DI water from the extracted formation water and re-circulated to the well bottom' via the solid riser.

Use the water level meter to observe the elevated total head during emplacement. If borehole conditions permit (i.e. the absence of constricted borehole intervals), the logging tool is used to monitor the advancement of the fluid up the borehole as it displaces the standing formation water. Draw the logging tool up the wellbore in successive increments as the DI water is emplaced. Monitor the electrical conductivity of the fluid expelled from the evacuation pump during emplacement procedures. When FEC values are representative of the DI water, or sufficiently diluted formation water, terminate emplacement procedures.

Emplacement is complete when DI water, or sufficiently diluted formation water, is observed from the evacuation pump or when logging tool stationed near the pump indicates DI water or sufficiently diluted formation water.

Upon completion, turn off the evacuation pump. Then turn off the injection line.

18.) Record volumes of extracted and injected fluids on the well testing data form.

Calculate the volume of DI water lost to the formation.

19.) Take initial background HydroPhysicalm log, or begin continuous logging depending upon extraction method ( i.e. slug vs. continuous).

20.) Pumping and testing procedures vary depending. upon wellbore hydraulics and construction detail.

21.) Continuous logging is conducted until stabilized and consistent diluted FEC logs are observed. If inflow characterization at a second pumping rate is desired, increase extraction rate and assure the proper DI water injection rate. Perform continuous logging until stabilized and consistent FEC logs are observed and all diluted formation water is re-saturated with formation water.

0 2004, COLOG

22.) After stabilized and consistent FEC traces are observed, terminate DI water injection. Reduce the total extraction flow rate to the net formation rate and conduct continuous logging. Conduct logging until stable and consistent FEC values are observed.

23.) Conduct depth specific sampling at this time.

24.) At the conclusion of the above procedures, assess the wellbore fluid conditions and compare them with those ob'served during the original pumping (Step 14).

25.) Turn all pumps off. First remove the extraction pump from the borehole. During removal, thoroughly clean the evacuation line (2-inch o.d.) with a brush and alconox and rinse DI water. Also clean the outside of the pump. Place the pump in a drum of DI water and flush DI water through the system.

Remove the tool. Clean the wireline for the tool in a similar manner during its withdrawal from the borehole.

Remove the injection line from the well. Follow the same procedures when cleaning the injection line as for the evacuation line.

Store the pumps and logging tools properly for transport.

Place cover on well and lock (if available).

4. Special Notes On-site pre-treatment of groundwater using activated carbon, can be conducted prior to DI water generation, if there is a contaminated groundwater source. In addition, on-site treatment can also be considered to handle extracted fluids that would require containerization and treatment prior to disposal.

The rate(s) of pumping are determined by drawdown information previously obtained or at rate(s) appropriate for the wellbore diameter and saturated interval thickness. The appropriate extraction rate is a function of length of saturated interval, borehole diameter, and previous well yield knowledge. The appropriate pumping procedures to be employed are also dictated by the length of the exposed rock interval. In general, the extraction flow rate should be sufficient to induce adequate inflow from the producing intervals.

The concern is that the extraction flow rate does not cause extreme drawdown within the well i.e. lowering the free water surface to within the interval of investigation.

5. Discussion LOW YIELD: Extraction Slug Test After DI water Emplacement 02004, COLOG

In wells with very low total flow capability (i.e. < 0.10 gpm/foot of drawdown), perform a slug test in accordance with procedures developed by Hvorslev (1951). Rapidly extract a small volume of water from near the free water surface using the extraction riser and pump. A drop in piezometric head of about 2 feet should be adequate for the initial test.

Record the rise in the free *vater surface with time and develop a conventional time-lag plot.

When the free water surface has recovered to a satisfactory elevation, log the wellbore fluid conditions. Repeat the procedures described above with successive increases in the drop of piezometric head (or volume extracted). Let the wellbore recover and record the rise in the free water surface. Repeat logging of the wellbore fluid after the free water surface has recovered to a satisfactory elevation. The number of slug tests performed is determined in the field after review of previous logging results.

MODERATE YIELD: Time Series HydroPhysicalm" Logging During Continuous Pumping After DI water Emplacement In the case of moderate yield wells (i.e. 0.10 < Y < 4 gpm/foot of drawdown), maintain a constant flow rate from the evacuation pump and record the total volume of groundwater evacuated from the wellbore. Employ a continuous reading pressure transducer (or equivalent device) to monitor the depressed total head during pumping, along with the associated pumping rate.

Hold the flow rate from the evacuation pump constant at a rate determined for the specific borehole. Drawdown of the free water surface produced during pumping should not overlap any identified water producing interval. Conduct hydrophysical logging continuously. The time interval is a function of flow rate and is specific to each well.

The number of logging runs and the length of time required to conduct all loggings is a function of the particular hydraulic conditions. Logging and pumping is continued until the fluid column is re-saturated with formation water (i.e. all DI water is removed from the borehole).

HIGH YIELD: Time Series Wellbore Fluid Logging During Continuous Pumping and Simultaneous DI Water Injection When wells exhibit high yield (> 4 gpm/foot of drawdown), as determined by a review of the interval of interest, the borehole diameter and the results obtained from previous information and preliminary hydraulic testing, the appropriateness of time series fluid logging during continuous pumping and simultaneous DI water injection is determined.

In this case, maintain a constant flow rate from the evacuation pump and record this rate and the associated drawdown. During this period, conduct hydrophysical logging until reasonably similar HydroPhysicalTm logs are observed and stabilized drawdown is achieved. After reasonably similar downhole fluid conditions .are observed and simultaneous with extraction pumping, inject DI water at the bottom of the well at a constant rate of 10 to 20% of that employed for extraction. Increase the total rate of 0 2004, COLOG

extraction to maintain total formation production reasonably similar to that prior to DI water injection (i.e. increase the total extraction by amount equal to the DI water injection rate).

Periodically record the total volume and flow rate of well fluids evacuated and the total volume and flow rate of DI water injected. Use a continuous reading pressure transducer or similar device to monitor the depressed total head during pumping. Record the depressed total head (piezometric surface) periodically, with the associated pumping and injection data.

The evacuation and DI water injection flow rates are held constant at a rate determined for the specific wellbore. Drawdown of the free water surface during pumping must not overlap any identified water producing intervals. HydroPhysicalTm Logging is conducted continuously. The number of logging runs and the length of time required to conduct all loggings is a function of the particular hydraulic conditions exhibited by the well under investigation.

Abstract Dynamic wellbore electrical conductivity logs provide a valuable means to determine the flow characteristics of fractures intersecting a wellbore, in order to study the hydrologic behavior of fractured rocks. To expedite the analysis of log data, a computer program called BORE II has been developed that considers multiple inflow or outflow points along the wellbore, including the case of horizontal flow across the wellbore. BORE II calculates the evolution of fluid electrical conductivity (FEC) profiles in a wellbore or wellbore section, which may be pumped at a low rate, and compares model results to log data in a variety of ways. FEC variations may arise from inflow under natural-state conditions or due to tracer injected in a neighboring well (interference tests). BORE II has an interactive, graphical user interface and runs on a personal computer under the Windows operating system. BORE 11 is a modification and extension of an older code called BORE, which considered inflow points only and did not provide an interactive comparison to field data. In this report, we describe BORE 1I capabilities, provide a detailed user's guide, and show a series of example applications.

1. Introduction The variation of formation permeability surrounding a wellbore is usefutl information not only for identifying hydraulically conducting fractures or other high-conductivity features intercepted by the well, but also for quantifying the heterogeneity of the medium. These are essential data in the evaluation of in-situ flow and transport characteristics at a given site.

Methods to evaluate permeability values along the depth of a well include the packer method, in which constant pressure, constant flow, or pulse tests are conducted in packed-off intervals in a wellbore, and various downhole flow meters. The packer method has the disadvantage that it is very time consuming and costly, and the vertical resolution is limited by the interval between the two packers that can be set in the well. Flow meter methods such as spinners and heat pulse flow meters generally allow better vertical resolution than the packer method, but they are not as accurate in determining permeability, because they mostly measure the wellbore fluid velocity, which is very sensitive-to variations in the wellbore radius.

In 1990, Tsang et al. (1990) proposed a method using logs of fluid electric conductivity (FEC) at successive times under constant-pumping conditions to obtain inflow from the formation into the well as a function of depth in the well. In this method, the wellbore is first filled by de-ionized water or water of a constant salinity (i.e., ion concentration) distinct from that of the formation water. This is usually done by passing the de-ionized water down a tube to the bottom of the wellbore at a given rate while simultaneously pumping at the top of the well at the same rate. After this is done, the well is pumped at a constant flow rate, which can be adjusted to optimize wellbore flow conditions. An electric resistivity probe is lowered into the wellbore to scan FEC as a function of depth along the wellbore. This is what is called fluid conductivity logging. A series of five or six such logs are obtained at time intervals over a one-or two-day period. At the depth levels where water enters the wellbore, the conductivity log displays peaks, which grow with time and become skewed in the direction of water flow. By analyzing these logs, it is possible to obtain the permeability and salinity of each hydrologic layer transmitting water. The method has been very successful, being much more accurate than flow meters and much more efficient (much cheaper) than packer tests (Tsang et al. 1990),

particularly in low permeability formations. A typical I 000-m section in a deep hole can be tested in two or three days at a spatial resolution of -0.10 m all along the length of the wellbore 2

section. The method is now being widely used in Europe and the U.S. (Marschall and Vomvoris, 1995; Pedler et al., 1992; Bauer and LoCoco, 1996), both under natural-state flow conditions and while tracer is injected in a neighboring well (i.e., interference tests).

Along with the method, a code was developed called BORE (Hale and Tsang, 1988),

which performed the forvard calculation to produce wellborc FEC profiles given different inflow positions, rates, and concentrations. The code has been well used over the last decade.

However, it appears now that there is a need to revise the code to make it more suitable for current computer environments and to add new capabilities. Thus, the code has been updated to run under current operating systems, provide interactive modification of model parameters, and produce graphical comparisons between model and field data. More importantly, the revised code allows the possible inclusion of both flows into and out of the well at various depths, a feature that has been observed in real field conditions when different layers penetrated by the well have different hydraulic heads. Furthermore, the new code allows the calculation of the case with equal inflow and outflow at the same depth level, which is effectively the special case of horizontal flow across the wellbore. Drost (1968) proposed a measurement of solute dilution in the wellbore to evaluate ambient horizontal flow velocity in the formation and it has become a well-accepted method. The new code provides the opportunity to analyze such cases and to identify the depth interval of horizontal flow to within -0.1 m as well as to estimate the flow rate. Moreover, one can analyze the combination of horizontal flow across the wellbore and vertical diffusion or dispersion along the length of the wellbore, which is not possible with Drost's solution.

The report is organized as follows. In Section 2, the basic capabilities of the revised code, called BORE II, are described, and the key parameters associated with BORE II are defined. Details of the mathematical background and numerical approach are described in Appendix 1, which is adapted from Hale and Tsang (1988). A user's guide is presented in Section 3, which includes a description of BORE II's interactive user interface, required input items, and options available when running BORE II. Four example applications are given in Section 4 to conclude the report.

We are still open to further improvements of BORE II; any suggestions and comments are invited and should be addressed to the authors.

2. BORE II Capabilities BORE II calculates FEC as a function of space and time in a wellbore containing multiple feed points given the pumping rate of the well, the inflow or outflow rate of each feed point, its location and starting time, and, for inflow points, its ion concentration. A simple polynomial correlation between ion concentration, C, and FEC is assumed. Ion transport occurs by advection and diffusion along the wellbore, with instantaneous mixing of feed-point fluid throughout the wellbore cross-section. These assumptions allow use of a one-dimensional model. BORE 1I divides the wellbore section under study into equal height cells and solves the advection/diffusion equation using the finite difference method. Further details of the mathematical and numerical approach are given in Appendix 1.

Inflow and Outflows Feed Points The original BORE code (Hale and Tsang, 1988) considered inflow points only, so flow through the wellbore was upward at all depths. BORE 11 allows both inflow and outflow points, so flow in the wellbore can be upward, downward, or horizontal at different depths and flow at either end of the wellbore section being studied can be into or out of the wellbore section or be zero. By convention, upward flow in the wellbore is positive and flow into the wellbore is positive.

Steady and Varying FluidFlow The original BORE code considered steady fluid flow, so feed points had constant flow rates. They also had constant concentrations, but delayed starting times for feed-point concentration to enter the wellbore were allowed. BORE II permits both steady and varying fluid flow. For the steady-flow case, the user specifies flow rate, concentration, and concentration start time for each feed point, but for outflow points (those with negative flow rates) the concentration and concentration start time are not used. Variable flow rate or concentration can be specified for feed points by interpolating from a table of time, flow rate, and concentration. If a table includes both positive and negative flow rates (i.e., a feed point alternates between inflow and outflow), the concentration for the positive flow rate is used when interpolating between positive and negative flow rates.

4

ConcentrationBoundary Conditions If the flow at the top of the wellbore section under study is into the wellbore, the initial concentration for the uppermost cell in the wellbore is used as the inflow concentration.

Analogously, if flow at the bottom of the wellbore section is a flow up from greater depths, the initial concentration for the lowermost cell in the wellbore is used as the inflow concentration.

Furthermore, for inflow points with a concentration start time greater than zero, the initial concentration of the wellbore is used as the inflow concentration for times less than concentration start time.

HorizontalFlowt' The special case of horizontal flow through the wellbore, as described by Drost (1968),

can also be considered, by locating an inflow point and an outflow point with equal magnitude flow rates at the same depth. The flow rates may be specified as either (1) the Darcy velocity through the aquifer or (2) the volumetric flow rate into/out of the wellbore. BORE II multiplies Darcy velocity by the cross-sectional area of the feed point (wellbore diameter times cell height) and Drost's ah convergence factor to convert it to a volumetric flow rate. The value of ah can range from I (no convergence) to 4 (maximum possible convergence, which occurs for the case of a thick, highly-permeable wvell screen). Drost suggested that for a uniform aquifer with no well screen, ah = 2, and that for typical applicationsa good choice for ah is 2.5. Horizontal flow feed points may have time-varying flow rates, but for Darcy-velocity calculations to make sense, the inflow and outflow rates must be equal and opposite at any time. Thus, if a feed point location changes from a horizontal flow point to a non-horizontal flow point with time, volumetric flow rates must be specified rather than Darcy velocities.

3. BORE II User's Guide OperatingSystem BORE II may be run under Windows 95, 98, or 2000 by double-clicking the executable icon (BOREII.EXE) in Windows Explorer, by double-clicking on a desktop shortcut key to BOREII.EXE, or by typing BOREII in the Run command in the Start Menu or in a DOS-prompt window. BORE II will not run in stand-alone DOS or in the DOS-mode of Windows. BORE II was compiled using Microsoft Fortran PowerStationTm Version 4.0, but this software is not necessary to run the program.

BORE II GraphicalOutput The primary user interface with BORE II is interactive, with the user responding to on-screen prompts to modify model parameters and choose options (described below) for the real-time graphical display of model results and data. The basic BORE II output screen consists of three windows.

  • The borehole profile window shows FEC profiles as a function of depth and time.

Simulation time t is shown in the upper left corner. Fluid flow rate at a user-specified depth in the wellbore, qo, is shown in the middle of the top line (the depth at which qo is calculated is set by option P). The depth of a C-t plot is also shown.

  • The inflow parameters window shows the feed-point characteristics for the model that can be modified with option M (location, flow rate, and concentration). Often there are more feed points than can be displayed at once on the screen. BORE II starts out showing the first few (deepest) feed points, then shows the feed points in the neighborhood of any point that is being modified.
  • The dialog window allows the user to select options (described below) when running BORE 11.

On computers with small screens, it may be desirable to run BORE II in full-screen mode, so that the entire BORE II screen can be seen at once without scrolling. Full-screen mode is entered by pressing Alt-VF (or on some computers by pressing Alt-Enter). Pressing Esc (or 7

Alt-Enter) terminates full-screen mode. There are three potential problems associated with the use of full-screen mode.

(1) The status line describing what BORE II is doing (e.g., running, waiting for input) is not visible.

(2) Drawing an x-t plot (options X, S, D, F, and 1), which creates a new window, may be very slow and the graphics quality poor.

(3) On some computers, text is difficult to read after closing the x-t plot window.

To address the latter two problems, one may terminate full-screen mode before using options X, S, D, F, and 1. The new window will be small, but after drawing is complete it may be expanded by pressing Alt-Vy to enter full-screen mode. Full-screen mode should be terminated before the new window is closed to avoid the final problem.

To print an image of the screen, press Alt-PrintScreen to copy the screen image into the clipboard. Then open a program such as Microsoft Paint and paste in the image. It can be manipulated, saved in a variety of graphics formats, or printed from Paint. The image can also be pasted directly into another Windows application such as MS Word.

Input/Output File Overviews Running BORE II requires one or two external files: a file with an initial set of model input parameters (mandatory, known as the input file) and a file with observed data (optional, known as the data file). These files are plain ASCII text, and must reside in the same folder as the BORE II executable. The input file contains model parameters such as the depth interval being studied, feed point characteristics, problem simulation time, and C-to-FEC conversion factors. The data file contains observed values of FEC and temperature, and optionally contains other fluid properties such as pH. Detailed instructions for preparing an input file and a data file are given below.

BORE II always creates a temporary file, called BOREII.TMP (see options C and R), and optionally creates a new input file (see option V), which is useful if model parameters have been changed during the BORE II run.

Line-by-line Instructionsfor Input File After starting BORE 11, the user is prompted to choose the input file from the list of files residing in the folder-where the BORE II executable is. Input file names with more than 8 characters before a period or blanks vill appear in the list of files in an abbreviated form. File names can be at most 20 characters long.

A sample input file is provided that can be modified as needed using a text editor such as Notepad or a word processor such as MS Word. If a word processor is used to create or modify an input file, be sure that the file is saved as plain ASCII text.

The input file is designed to be self-documenting, with header lines preceding data lines.

These header lines must be present, but BORE II does not use the text on them. Data entries are read in free format, with individual entries on a given line separated by blanks, tabs, or commas.

This means that entries cannot be left blank, even if they are not being used (e.g., concentration for an outflow point). Unused entries may be set to zero or any convenient value. Comments may be added on data lines, after the requisite number of entries. In the sample input file, comments begin with an exclamation point.

The third feed point has variable flow rate and concentration, with a five-entry table specifying the variation with time. The fourth feed point is an inflow point with constant flow rate and concentration and a non-zero concentration start time.

Note that the flow from below, qw, is positive (into the wellbore section), so the corresponding concentration is specified as the initial condition of the lowermost cell in the wellbore (at x = Xmi) by using ICOFLAG = 1. If ICOFLAG = 0, the concentration associated with qu would be zero, and if ICOFLAG = -1, the concentration associated with qu. would be the uniform non-zero initial concentration in the wellbore.

When BORE II writes an input file (option V), it changes several things to the file form shown above. Comments found in the original input file are not reproduced, but two comments are added. First, the cell height and the equation used to calculate it are shown on the line with Xmin, xmaE, and dw. Second, if feed points represent horizontal flow, then the flag IINVF is set to 0, flow rate is given in L/min, and the corresponding Darcy velocity through the aquifer in m/day is added as a comment. Finally, if ICOFLAG > 0, BORE II sets ICOFLAG to the number of wellbore cells, and explicitly shows every (x, Co(x)) pair. This option is useful for identifying the x values of various cells, which may expedite assignment of feed point locations or initial conditions. Part of the input file created by BORE II for the above sample is shown below.

Line by Line InstructionsforDataFile The data file is read in the fixed format shown below. If data are available in a different format, an auxiliary program should be used to convert it to this form (a simple preprocessor called PREBORE, described in Appendix 2, converts the data file format used by BORE to the new format shown below). Note that because a fixed format is used, blank entries are allowed; they are interpreted as zero.

Lines 1-8 are header lines, not used by BORE II.

Each line of the remainder of the file contains:

Note that there is one blank column before each of the HR, MIN, and SEC entries, to make the data file more readable. The first time entry corresponds to t = 0 for the model.

BORE II Options The following options are available on the BORE II main menu. Either uppercase or lowercase letters may be used, and should be followed by pressing ENTER.

C - (C)-x plot - Displays FEC versus depth for data and/or model continuously in time (an animation); stores [x (in), t (sec), data FEC (pS/cm), model FEC (piS/cm)] in file BOREII.TMP for later use by option R or post-processing.

T - c-(T) plot - Displays FEC versus time for data and model for a chosen depth.

R - d/m cu(R)ve - Displays FEC versus depth plots for data and model at a series of times (snapshots of the option C display); uses results of most recent option C, read from BOREII.TMP. Does not work if there is no data file or if there are only data at one depth in data file.

N - i(N)flow-c - Displays inflow FEC for a chosen feed point as a function of time.

14

A - p(A)ram display - Displays all data profiles (FEC, TEMP, DAT3, DAT4, DAT5) simultaneously, using user-specified plot limits (selections 3-6). For selection 1, all points are connected on one continuous curve; for selection 2, points that are beyond depth or time limits start new curve segments.

X - (X)-t plot - Displays a color-coded plot of model FEC versus depth and time in a new window, then repeats the plot in the borehole profile window.

S - tool (S)tudy x-t plot - Same as X, but limits display to what would be obtained with a tool whose parameters (number of probes, gap between probes, and tool velocity) are specified by the user.

D - (D)ata x-t - Displays a color-coded plot of data traces versus depth and time in a new window, then repeats the plot in the borehole profile window (data type specified by option Y, default is FEC).

F - (F)ill data x-t - Same as D, except that data traces are interpolated to fill the x-t plane.

I - dim d(I)ff x-t - Displays a color-coded plot of the difference between model and data FEC versus depth and time in a new window, then repeats the plot in the borehole profile window.

User selects whether to show data traces (mode 1) or filled data (mode 2).

M - (M)odify inp- Opens interactive session for modifying location, flow rate, and concentration of feed points, or adding new feed points. User is prompted to enter feed point number and given the chance to modify or maintain current parameters. To add a new feed point, specify a feed point number greater than that for any existing feed point. If horizontal flow is implemented using option M, flow rate must be specified as volumetric flow rate through the wellbore in L/min.

P - (P)lot adjust - Sets new values of parameter minimum and maximum; tmlX; difference range for option I; and depth for which wellbore flow rate qo is displayed in borehole profile window (default depth is xmin).

G - (G)rid - Sets grid spacing for new window showing x-t plots.

Y - data t(Y)pe - Chooses data type (FEC, TEMP, DAT3, DAT4, DAT5) to display in options C, T, D, and F. Model results always show FEC, so option C and T plots, which show both model and data, must be read carefully. Note that options R and I are not affected by the choice of data type, but always compare model and data FEC.

Z - print - Displays instructions for printing a screen image.

V - sa(V)e - Creates a new input file with current model parameters. User is prompted for new file name.

Q - (Q)uit - Terminates BORE II program.

4. Example Applications Five example applications are presented to illustrate the capabilities of BORE I.

Although BORE 1I simulates the forward problem (it produces wellbore FEC profiles given different inflow positions, rates, and concentrations), it is most commonly used in an inverse mode, in which inflow positions, rates and concentrations are varied by trial and error until the model matches observed values of wellbore FEC profiles. Initial guesses for the trial and error process may be obtained using direct integral methods (Tsang and Hale, 1989; Tsang et al.,

1990) or other means (see example 2 below). Example applications 3, 4, and 5 demonstrate such comparisons to real data provided to us as typical field data sets by G. Bauer (private communication, 2000). The results of these example applications do not necessarily provide physically realistic flow rates and inflow concentrations, because they employ the artificial equality FEC = C. Furthermore, rough matches to real data, as are obtained here, can often be obtained equally well with a variety of different parameters (i.e., the solution of the inverse problem is non-unique). The input files for the example applications are shown in Appendix 3.

1. Up Flow -Numerically SimulatedData Perhaps the most common application of BORE 11 is to the case of up flow - when one pumps from the top of the wellbore section, and fluid enters the wellbore at one or more feed points. Figure I shows C versus x for several times for a typical up flow case (obtained with BORE II option R). Each feed point has the same inflow rate and the same concentration, and there is also up flow from below. At early times, the feed points show up as individual FEC peaks, but as time passes, the deeper peaks merge with those above them, creating a step-like structure. The data set for this example is not real, but the results of a numerical simulation using the flow and transport simulator TOUGH2 (Pruess, 1987; 1991; 1995; 1998). TOUGH2 has been verified and validated against analytical solutions, other numerical models, and laboratory and field data. The TOUGH2 simulation uses a one-dimensional model with the same cell spacing as BORE II and constant mass sources located at the BORE 11 feed points. Thus, BORE II and TOUGH2 are solving the same problems, and comparing the results for wellbore FEC profiles verifies that the BORE II calculations are done correctly.
2. HorizontalFlowv -Analytical Solution andNimerically Simulated Data For horizontal flow in the absence of diffusion/dispersion along the wellbore, an analytical solution for the concentration observed in the wellbore as a function of time, C(t), is given by (Drost, 1968):

C(t)= C; -[C; - C(O)]exl tvdah), (1) where Ci is the formation (inflow) concentration, t is time (s), vd is the Darcy velocity through the aquifer (mis), ah is the aquifer-to-wellbore convergence factor, and rw is the wellbore radius (m). Figure 2 shows the analytical solution and the BORE II results for this problem, obtained using option T. The agreement is excellent. Note that for small values of vd, if C(O) = 0, the analytical solution becomes approximately C(t) =Ci IIl- expl (-2tVdat, Ctt1-Žah11 C.2trla.

da>JJ (2) 71r,,7rr,,7tir" 17

Thus, any combination of C, and vd whose product is a constant gives the same value of C. This condition corresponds to the early-time straight-line portion of Figure 2. The analytical solution may be implemented in a spreadsheet to expedite the choice of BORE 11 parameters, by examining the solution for various values of vd and Ci. Note that care must be taken to use a consistent set of units for t, vd, and rw in Equations (I) and (2). For example, when time is in seconds, BORE 11 input parameters vd in m/day and r,. in cm must be converted to m/s and m, respectively.

Figure 2 also shows the evolution of concentration at and near a horizontal flow layer when diffusion/dispersion along the wellbore is significant (Do = l m2 /s). For this case, the analytical solution is not applicable, but BORE 11 results compare very well to numerically simulated data obtained using TOUG1H2. When dispersion is significant, use of the Drost solution generally results in an underestimation of C, and an overestimation of vd. These errors do not arise when using BORE II, since diffusion/dispersion can be explicitly included.

HorizontalFlow,- Real Data As indicated in Figure 2, the addition of diffusion or dispersion modifies the depth-FEC profile arising from a thin layer of horizontal flow, by widening the base of the FEC peak. A thick layer of horizontal flow produces a distinct signature, with an FEC response that has a wide peak as well as a wide base. To model a thick layer of horizontal flow, one may use several adjacent inflow/outflow point pairs in the model. Figure 3 compares model and data profiles (G.

Bauer, private communication, 2000) of C versus x for several times, using option R. Seven pairs of inflow/outflow points are used, assigned to seven adjacent cells. By multiplying the number of inflow/outflow pairs by cell thickness, one may estimate the thickness of the layer of horizontal flow, in this case 2.3 m. See Appendix 1, Section Al .5, for additional information about assigning feed points to specific cells.

For this particular data set, the earliest observations show a variable FEC profile. One possible way to address this is to specify a non-uniform initial concentration distribution in the wellbore. An alternative approach (used here) is to add a dummy entry to the data file, specifying a time prior to the first real data time, at which the FCE distribution in the wellbore is assumed to be uniform. In general, it is not possible to determine when, if ever, the FEC distribution in the wellbore is uniform, but the approach can work quite well, as shown in Figure 18

4, which shows C versus t at the center of the horizontal flow zone (option T). The data zero time taken from the header of the data file, where the date and time of the logging run are specified.

4. Dovn Flow -Real Data Figure 5 compares model and data profiles (G. Bauer, private communication, 2000) of C versus x for several times (option R) for a case with primarily down flow. A uniform non-zero initial concentration is used (ICOFLAG < 0) to approximate the low, slightly variable initial concentration. Two shallow inflow points have variable concentrations that increase in time, which suggests that de-ionized water penetrated into the fractures when it was introduced into the wellbore to establish low-concentration initial conditions for logging. A low-concentration feed point at x = 158.5 m creates up flow above it, but the remainder of the wellbore section shows down flow.
5. CombinationFlowv -Real Data Figure 6 compares model and data profiles (G. Bauer, private communication, 2000) of C versus x for several times (option R) for a case with combination flow. A non-uniform initial condition has been used, which is extracted from the data file using the preprocessor PREBORE (see Appendix 2). Note that there are more entries in the initial condition specification (232) than there are cells in the model (179). Thus, some cells are assigned more than one initial condition. For cells where this occurs, only the final initial condition assigned is used. See Appendix 1, Section A 1.5, for additional information on specifying non-uniform conditions.

Figure 7 showvs the same information as Figure 6, but plotted in a different way, with the difference between data and model FEC plotted as an x-t plot (option I). The blue and orange diagonal features indicate that the largest discrepancy betveen model and data gradually deepens with time.

Appendix 1: Mathematical Background and Numerical Approach The principal equation governing wellbore FEC variation is the equation for the transport of mass (or ion concentration) in the wellbore. However, additional consideration must be given to the determination of FEC as a function of ion concentration and the temperature dependence of FEC.

Al..1 FECas a Function of Concentration The relationship between ion concentration and FEC is reviewed, for example, by Shedlovsky and Shedlovsky (1971), who give graphs and tables relating these two quantities.

Hale and Tsang (1988) made a sample fit for the case of NaCI solution at low concentrations and obtained FEC = 1,870 C- 40 C2, (A.1) where C is ion concentration in kg/r 3 (= gIL) and FEC is in SS/cm at 20'C. The expression is accurate for a range of C up to st 6 kg/i 3 and FEC up to 11,000 gS/cm. The quadratic term can be dropped if one is interested only in values of C up to 4 kg/i 3 and FEC up to 7,000 ptS/cm, in which case the error will be less than 10%.

Fracture fluids typically contain a variety of ions, the most common being Na+, Ca2+,

Mg2+, Cl;, So02 , and HCO3 -. If a hydrochemical analysis has been completed, various methods are available for computing an equivalent NaCI concentration for other ions. Schlumberger (1984) presents charts of multiplicative factors that convert various solutes to equivalent NaCI concentrations with respect to their effect on electric conductivity.

A1.2 Temperature Dependence ofFEC BORE II calculations are made assuming a uniform temperature throughout the wellbore.

Actual wellbore temperatures generally vary with depth, so temperature corrections must be applied to field FEC data to permit direct comparison with model output.

The effect of temperature Ton FEC can be estimated using the following equation (Schlumberger, 1984) 22

FEC(200 C) - +S(T 20°C)' (A.2) where S = 0.024.

Generally, temperature increases with depth below the land surface. If full temperature logs are available, these data can be used to correct the corresponding FEC values. However, if no complete logs are available, a simplifying assumption may be made that the temperature variation in the wellbore is linear and can be modeled by:

T= Ax +B (A.3) where A and B are parameters determined by fitting any available temperature versus depth data.

If the fit is unsatisfactory, other relationships with higher order terms must be used.

AJ.3 GoverningEquation The differential equation for mass or solute transport in a wellbore is:

la(D aX a (~ac

((Cv)+S= a~(A.4) 8a, ~ A4 where x is depth, t is time, and C is ion concentration. The first term is the diffusion term, with Do the diffusion/dispersion coefficient in m2 /s, the second term is the advective term, with v the fluid velocity in m/s, and S is the source term in kg/m3 s. This one-dimensional partial differential equation is solved numerically using the finite difference method, with upstream weighting used in the advective term. The following initial and boundary conditions are specified:

C(x,0) = Co(x), (A.5)

C(xmin,t) = Co(xmin) for flow into the wellbore from above, C(xm,,t) = Co(xmax) for flow into the wellbore from below, Do = 0 for x <xin and x > xm.

The first condition allows for the specification of initial ion concentrations in the wellbore. The second and third conditions allow for advective flow of ions into the wellbore interval from above and below. The final condition indicates that diffusion and dispersion do not take place across the boundaries of the wellbore interval. In general, advection will be the dominant 23

process at the boundaries. If diffusion or dispersion is dominant for a particular problem, the boundaries should be extended in order to prevent improper trapping of electrolyte.

and diffusion At < -X 2 (A.7) 4D 0 '

where qmax (m3 Is) is the maximum fluid flow rate anywhere in the wellbore. BORE II starts its calculation at t = 0. The first time in the data file is also identified with t = 0. If it is apparent that model and data times are not synchronized, then one may insert an additional line into the data file after the header lines, with an earlier time than the first real data time, in order to reset the data zero time. On the inserted line, FEC, x, and other data entries may be left blank or copied from the first real data line.

Al.5 Discrefizationin Space The wellbore interval between xmi. and xmax is uniformly divided into N cells and it is assumed that the wellbore has uniform diameter, d. Cell height Ax is determined as the larger of (Xmax - Xm.n)/l 80 and d4. Position values indicate depth in the wellbore and thus x is zero at the surface and increases downward. The cell index increases upward, with cells I and N located at the bottom and top, respectively, of the wellbore interval. In general, the ith node (the center of the ith cell) is located at xi =xma. - (i-I/2)Ax, (A.8) with the ith cell extending from x. - (i - I)Ax to x. - iAx.

BORE II assigns feed points and initial concentrations to cell i if the location of the feed point or Co(x) value lies within the boundaries of the ith cell. If multiple feed points are assigned

-to the same cell, they will all be accounted for, but if multiple initial conditions are assigned to the same cell, only the final one assigned will be used. By definition, the lower boundary of cell 24

I is at xma,, but due to round-off errors, the upper boundary of cell Nmay not be atxmin. Hence, it is often useful to know the x coordinates of each node. These are displayed in the input file written by BORE II (option V) when ICOFLAG > 0. Thus, if the user sets ICOFLAG = 1, inputs one (x, Co(x)) pair, and uses option V, then a new input file will be created with ICOFLAG = N and a complete list of the x coordinates for all nodes, with Co = 0 for all cells except the one identified in the original input file. Alternatively, if the initial conditions are taken from the data file with PREBORE (or taken from any source that is independent of the nodal coordinates), then using option V will create an input file that shows the actual initial conditions assigned to each cell.

The list of nodal x coordinates may be useful when modeling a thick fracture zone or aquifer, in order to place one feed point in each cell over a given depth range. Similarly, when using ICOFLAG > 0 to specify non-uniform initial concentrations, one must assign a Co value to each cell in the interval of interest in order to obtain a continuous C profile, because no interpolation is done between scattered initial concentrations. Finally, knowing the coordinate of the top cell in the model is useful for assigning the initial concentration that serves as the boundary condition for inflow into the wellbore interval from above. For inflow from below, either x = xl or x xma. may be used.

A].6 Calculation ofFlowv Rates Feed point flow rates may be constant in time, in which case a steady-state flow field is assumed in the wellbore, or variable, with feed point flow rates determined by linear interpolation between tabulated values. Although feed point flow rate may vary, true transient wvellbore flow including fluid compressibility effects is not considered. Rather, the wellbore fluid flow field is assumed to change instantly from one steady-state flow field to another. In other words, the flow rate out of cell i is always the sum of the flow rates from all feed point locations within the boundaries of cell i plus the flow rate out of cell i-I.

Appendix 2: The Preprocessor PREBORE PREBORE is a simple Fortran program that does preprocessing for BORE H. It runs under either Windows or DOS. PREBORE converts the old BORE data file format into the new BOREII data file format. Depth is converted from feet to meters, and other data columns are realigned. PREBORE can also create a file with (xCo) pairs to be added to the BORE II input file as initial conditions (this option requires that x values steadily increase or steadily decrease in each profile).

If data file conversion is being done, the user is prompted to enter the old and new data file names.

If a file with initial conditions is being created, the user is prompted for the following information: the name of the BOREII data file; a name for the initial condition file; which profile in the data file to use; the direction of logging (downward assumes x values increase in the data file, upward assumes they decrease, and both assumes the profiles alternately increase and decrease in x); and the conversion factors (y, A,a) between FEC and C (default values 0, 1870, -40). In addition to creating an ASCII text file with (xCo) pairs, which may be added to the BOREII input file using a text editor or word processor, PREBORE prints out the number of pairs on the screen, which should be used for ICOFLAG. Note that ICOFLAG may be greater than the number of cells in the model (usually about 180), but that in this case not all the Co values will be used (see Appendix 1, Section A1.5).

Data file conversion and initial condition creation can be done in the same PREBORE run. In this case the user must specify both old and new data file names in addition to the parameters describing the creation of initial conditions.
