Letter MPK: 100533 - 452.2, B. C. Bower to R. J. Phaneuf, "West Valley Demonstration Project North Plateau Background Soil Characterization Report (WVDP-493), Rev. 2," dated March 4, 2009

Dear Mr. Phaneuf:

Enclosed is a copy of the WVDP North Plateau Area Characterization Report (WVDP-494).

The objective of this 2008 field investigation was to obtain subsurface soil and groundwater data for metals, organics and radiological constituents from areas under the WVDP Main Plant Process Building (MPPB), directly adjacent to the MPPB, and immediately downgradient of the MPPB. This generated data was used primarily to continue to assess if the source(s) of the North Plateau strontium (Sr-90) groundwater plume could have contained any Resource Conservation and Recovery Act (RCRA) constituents which impacted subsurface soils or groundwater.

If you have any questions regarding this report, please call Jennifer Dundas of my staff at (716) 942-4287.

Sincerely,

/

an C Bower, Director West Valley Demonstration Project

1.0 INTRODUCTION

1.1 General This report has been prepared by West Valley Environmental Services Company LLC (WVES) for the U.S: Department of Energy (DOE). The report presents the findings of the 2008 north plateau plume area subsurface soil and groundwater investigation conducted at the West Valley Demonstration Project (WVDP). During a June 7, 2005 meeting with the New York State Department of Environmental Conservation (NYSDEC), DOE stated that it would perform a characterization of subsurface soil and groundwater in the vicinity of and downgradient of the Main Plant Process Building (MPPB) area for the presence of Resource Conservation and Recovery Act (RCRA).metals above site-specific screening levels. The resultant data would be used to evaluate whether the RCRA metals, if present, may have originated from the groundwater plume source area. After further discussions with NYSDEC in February and March 2007, the scope of the investigation was expanded to include volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), polychlorinated biphenyls (PCBs) and radiological parameters.

The subsurface, investigation activities were implemented and completed following requirements detailed in WVDP-465, Sampling and Analysis Plan for Characterization of the North Plateau Plume Area (SAP) dated August: 16, 2007, prepared by West Valley Nuclear Services Company, Inc. (WVNSCO), for the DOE. This SAP was approved by NYSDEC in its correspondence dated November 5, 2007. This SAP's scope of work also included the evaluation of metals concentrations in groundwater from several rounds of sampling performed from July 2005 through November 2008 under a special groundwater monitoring program request.

1.2 Site Location The WVDP is located in western New York state about 30 miles south of Buffalo, New York in the Town of Ashford, Cattaraugus County. The WVDP facilities occupy a security-fenced area of about 167. acres within the 3,338-acre Western New York Nuclear Services Center (WNYNSC) as shown on Figure 1.

The WVDP is bisected by. Erdman Brook, which separates the site into the north plateau and south plateau (Figure 2). The north plateau area includes the MPPB. The location of the MPPB and plume characterization area sampling locations are presented on Figure 3.

1.3 Previous Investigations The WVDP, including the north plateau and MPPB area, has been the focus of significant historical subsurface characterization activities. In 1993,.gross beta activity in excess of the strontium-90 (Sr-90) DOE Derived Concentration Guide of 1.OE-06 pCi/mL was detected in surface water onthe north plateau. The gross beta activitywas determined to primarily result from the presence of Sr-

90. Records review and subsequent subsurface investigations identified the presumed primary source of the Sr-90 plume as originatingduring Nuclear Fuel Services, Inc. operations beneath the southwest corner of the MPPB. Subsequent investigations determined that the groundwater plume is slowly migrating towards the northeast quadrant of the north plateau. Historical investigations focused on background soil characterization, the Sr-90 plurme, and the MPPB source areas have been previously reported in the following documents:

1.4 Site Investigation ObjectivesI The principal goal of this investigation was to determine whether RCRA-regulated constituents are present in the subsurface (iLe., groundwater and soils) in the vicinity of and/or directly downgradient from the suspected MPPB source areas of the north plateau plume. The metals analytical data were evaluated with respect to site-specific background levels for metals. In addition, NYSDEC's Technical and Administrative Guidance Memorandum (TAGM) 4046 - Determination of Soil Cleanup Objectives and Cleanup Levels was used as a basis for evaluating reported I

concentrations of metals and organic chemicals in soil. NYSDEC's Division of Water's Technical and Operational Guidance Series (TOGS) 1. 1.1 - Ambient Water Quality Standards and Guidance Values and Groundwater Effluent Limitations was also used as a framework for comparing and assessing metals and organic chemical concentrations in groundwater in the investigation area.

Additional objectives of this investigation included the analysis of subsurface samples for radiological indicator parameters and select radioisotopes. Where metal concentrations exceed background, a comparison was~made to radiological concentrations to determine if a correlationi exists. The 2008 radiological data was also compared to previous subsurface sample results for radiological indicator parameters and select radioisotopes for comparison with metals concentrations. To characterize geochemical parameters.for potential future use in subsurface I

permeable reactive treatment wall design;, a selected depth interval was sampled for soil and groundwater at one location.

1.5 Report Organization 3

This report presents a summary of the field investigation activities and the results of the chemical and radiological analysis. The report has been organized into the following sections:

Section 1 - Introduction; Section 2 - Site Investigation Activities;,

Section 3 - Physical Conditions; Section 4 - Soil Data; Section 5 - Groundwater Data; Section 6 - Geochemical Data; Section 7-Data Validation Section 8 - Summary and Conclusions; and Section 9-References.

WVDP-494 Rev. 0 Page 7of 1158 2.0 SITE INVESTIGATION ACTIVITIES 2.1 General This section describes the field procedures that were used during the field investigation. As a precaution for the potential presence of radiological constituents, soil and groundwater samples were screened during sample collection for radiological activity using a portable Geiger-Mueller (GM) meter. The samples werealso screened for the presence of organic vapors with an organic vapor meter (OVM). Additional protocols required for health and safety purposes were performed in accordance with WVDP-010, WVDP Radiological Controls Manual (WVNSCO, 2006).

2.2 Sample Identification Each sampling location was uniquely identified by sample type (GP Which refers to Geoprobe),

sample location (e.g.,29, 30, 72, etc.)i and sampling year (-08), as well as a unique sequential Environmental Laboratory (ELAB) Information Management System (ELIMS) number. Sample containers were labeled with the unique ELIMS sample identification number, location, date, time of sample collection, sampler, and required analysis.

2.3 Soil Sampling To accomplish the investigation objectives, two Geoprobe borings (one for soil samples and one for groundwater samples) were advanced at each of 18 sampling locations by SJB Services, Inc.

(SJB), Hamburg, New York during the period of July 16 through September 10, 2008. The Geoprobe system is a.hydraulically activated, direct push soil probing method with percussion capabilities that allows discrete-zone soil and groundwater sampling. Boring logs for these 18 sampling locations are provided in Appendix A. Oversight wasperformed by personnel from Washington Safety Management Solutions (WSMS), a subsidiary of the Washington Division of URS Corporation. WSMS staff responsibilities for field activities included:

Coordinating SJB site activities; Field screening and logging of samples; Selection of sample intervals for collection; and Initiating and maintaining chain-of-custody (COC) documentation for handling, preservation, and release of samples to the WSMS ELAB and then to the off-site laboratory.

As shown onFigure'3, the sampling locations represented three site areas to optimize the likelihood of intercepting potential contaminants released from the suspected Sr-90 plume source areas: 1) directly beneath the MPPB, 2)-immediately adjacent to the east side of the MPPB and the Fuel Receiving and Storage Facility (FRS), and 3) slightly further east or northeast (downgradient) of the MPPB. The sampling locations were generally located in areas where previous investigations and groundwater monitoring have indicated some of the highest Sr-90 concentrations within the plume. As proposed in WVDP-465, five sampling'1ocations were identified within rooms or aisles of the first floor of the MPPB, including locations near or within the Cell Access Aisle, west Mechanical Operating Aisle, Product Packaging and Shipping, Ram Equipment Room (RER), and Uranium Load-Out. Four of the five locations inside the MPPB were.selected from previously sampled locations during the 1994 and 1998 Geoprobe investigations (see WVDP-220 and WVDP-346), locations that were accessible, and to optimize the likelihood of intercepting contaminants migrating from the suspected source areas. However, the boring location identified for the west Mechanical Operating Aisle (GP76-08) was moved into the north end of the RER, based on refusal being encountered.in multiple attempts in this area during previous investigations.

The 1994 and 1998 Geoprobe investigations focused mainly onradiological parameters.

Geochemical analysis for metals was not performed in the 1994 investigation and only for selected metals (i.e., aluminum, calcium, chloride, iron, magnesium, manganese, potassium, sodium, strontium, and zinc) in the 1998 investigation. Four sampling locations were located directly east of

WVDP-494 Rev. 0 Page 8 of i 158 the MPPB or directly adjacent the FRS (see Figure 4). The remaining nine locations are located slightly further east or slightly further downgradient of the MPPB in three northeast lines that trend in the general direction of groundwater flow.

At each sampling location, a Geoprobe Large Bore (LB) sampler equipped with a disposable, clear plastic liner was used to provide continuous soil samples from ground surface through the sand and gravel (S&G) unit into the saturated zone, terminating a minimum of two feet into the top of the Unweathered Lavery till (ULT) unit. If the underlying ULT was encountered before radioactivity levels returned to background or near background, then two soil samples were collected for analysis: one from the S&G unit just above the till interface, and one from the top two feet of the ULT.

The borings Were advanced by attaching the LB soil sampler to the lead probing rod and advancing the assembly to the top of the sampling interval. The piston stop-pin was detached from the inner rod allowing, the LB piston top to retract and the sampler to be driven 24 inches to obtain a discrete interval soil sample. The probe rods were retracted from the hole with the sample assembly.. The sampler was detached from the rods and was screened by a Radiation Control Technician (RCT) for the presence of radioactivity. The liner was placed onto clean plastic sheeting and a section of the plastic liner encasing the soil was removed and screened again.by the RCT for radioactivity.

Radioactivity detections ranged from background (100 to 300 counts-per-minute [cpm]) to 40,000 cpm (GP100-08).

The samples were subsequently screened by thesite geologist for the presence of organic vapors with an OVM prior to placing them in certified pre-cleaned sample containers. There were no detections of organic vapors during thescreening of the soil samples. The soil lithology of each sample was characterized using the Unified Soil Classification System and Burmeister lithologic descriptions in accordance with EM-500, Drilling, Soil Sampling and Geologic Logging Procedures.

Unsaturated soil (vadose zone) samples were collected for laboratory analysis at approximately 5-foot-depth intervals beneath and adjacent to the MPPB to characterize the top, middle, and bottom of this zone (locations GP29-08, GP30-08, GP72-08, GP76-08, GP78-08, GP80-08, GP100-08 and GP101-08). The vadose zone averaged approximately-18.1 feet in.thickness at these locations, which typically resulted in three unsaturated soil samples being collected. Soil boring logs (Appendix A) contain the field screening data and soil descriptions. Discussion of the subsurface conditions encountered in the Geoprobe borings is presented in Section 3.2.

Saturated zone soil samples were collected for analysis at three (or more) depth intervals at all boring locations. The first sample was collected from the uppermost two feet of the saturated zone.

The second sample was collected over the interval having the highest radioactivity, based on the response of the GM meter. The third saturated soil zone sample was collected from the first two-foot sample interval after radioactivity levels returned to background or near-background levels.

During the collection of these samples, one additional soil sample was collected at GP72-08 specifically for geochemical analysis. As planned, two soil samples were collected for analysis in areas where the underlying ULT was encountered before activity levels decreased significantly. In these instances, one samplewas collected from the S&G unit just above the till interface, and one sample was collected from the top two feet of the ULT at boring locations GP30-08, GP76-08, GP78-08, GP83-08, GP104-08, GP107-08, and GP109-08. Total depths of the soil borings ranged from approximately 6.1 to 43 feet below ground surface., Soil borings GP75-08 and GP108-08 encountered refusal at the shallower depths of 6.1 feet and 26 feet, respectively. A second attempt was made to advance a Geoprobe approximately one, foot away from GP75-08; however, refusal was, again encountered at a depth of.6.1 feet.: A-third attempt was made, but terminated as rebar was encountered in the concrete. Similarly, three attempts were made at GP108-08 to advance drill rods through the S&G unit to the ULT. All three attempts were met with refusal. Each.

subsequent attempt to advance drilling equipment was within approximately one foot of the original location. Boring GP72-08 had to be moved approximately one foot to allow for completion of soil sampling from 40. to 44 feet, due to insufficient recovery in initial borehole. Boring GP83-08 was I

WVDP-494 Rev. 0 Page 9 of 1158 moved approximately one foot to complete sampling activities after downhole sampler was lost in the borehole. Boring location GP105-08 was moved approximately 10 feet to the south after encountering refusal at approximately one foot in two separate attempts. A summary of soil.

sample collection depth intervals is included in Table 1.

Deviations.from the.SAP occurred at locations GP75-08 and GP108-08. Only one soil sample was collected from location GP75-08 at.4-6 feet bgs due to a refusal at a depth of 6.1 feet. One soil sample wascollected at.location GP108-08 at 12-14 feet bgs, also.due to a refusal at a depth.of 26 feet. NYSDECwas notifiedof the refusals encountered.'

Samples retained for laboratory analyses were placed in certified pre-cleaned sample containers.

Each container was affixed with an ELIMS label that included a unique sample number, location, depth interval, date, time of sample collection,'sampler, and required analyses. The containerized samples were surveyed by an RCT, and placed' in shipping coolers.for delivery to General Engineering Laboratories, LLC (GEL) of Charleston, South Carolina under COC. The chemical and radiological constituents for soil sampling analyses are presented in Appendix B.

Soil samples that were not selected for laboratory analyses were containerized as noted above, except for the ELIMS sample number and "required analysis." The samples are held-in storage for, future use, or reference as necessary, in accordance with the SAP.

,(.

The process described above was repeated at each -subsequent sampling location. The borings were abandoned upon completion by backfilling with bentonite chips. The downhole equipment

...was decontaminated prior to use at each sampling location. Prior to leaving the site, the rig and sampling equipment were radiologically, screened and/or decontaminated in accordance with procedures identified'in Section 3.6 of the SAP. Soil and.other related investigative derived waste was managed in accordance with Section 3.7 of the 'SAP.

The SAP called for termination of theborings when the S&G unit had' been fully penetrated and the top of the ULT unit had been confirmed. However, if GM meter-measured radioactivity levels at.

that depth did not return to background or near background levels, an additional, sample of the top two feet of the ULT was collected. As a consequence, the total depth of the individual borings and the selection of the intervals for subsequent laboratory analysis were modified in the field, based on

-conditions actually encountered, as deemed appropriate by the field sampling team and. Project' Manager.

The geologic units identified for the subsurface soil samples for the north plateau area characterization program were as follows:

TBU - 47 samples submitted for laboratory analysis; SWS - 24 samples submitted for laboratory analysis', and.

The third groundwater sample was collected from t~he base (i.e., bottom two feet) of the S&G unit. As planned, at GP72-08, 'an additional groundwater sample Was collected at a depth interval of.20 to 22 feet specifically for geochemical characterization.

Groundwater samples were collected by advancing a sampling screen' assembly inside of the lowermost rod equipped with a detachable sacrificial point to the desired 'sampling interval. The rods Were then retracted two feet to expose the screen assembly attached to disposable, 3/8-inch-diameter plastic tubing extending up to the surface. *Using a peristaltic pumpi, the screen. assembly.

After the sampling assembly and tubing were allowed to recharge with, groundwater representative of the desired sampling depth,.the required sample volume needed for analysis was 'collected. Groundwater samples collected for chemical analyses were hot filitered. All samples collected for radiological analyses were field-filtered with a 0.45 micron 'in-line filter, as well as some, geochemical samples collected. Groundwater depth intervals sampled for each boring site are indicated in Table 1 Samples retained for analyses by GEL were' placed in certified pre-cleaned sample cont'ainers.

Soil and groundwater samples were shipped by overnight courier under COC procedures outlined in EM-52,to GEL, a NYSDOH ELAP-certified laboratory for chemical and radiological analyses.

GEL's services were performed in conformance with WVDP quality control proCedures, outlined in their contract, which implement all applicable requirements of NQA-1, Quality Assurance Program Requirements for Nuclear Facilities.

Soil samples were analyzed for the U.S. Environmental Protection Agency (EPA) Contract Laboratory Program Target Analyte List (TAL) metals and Target Compound List (TCL)VOCs, SVOCs, and PCBs. Groundwater samples were analyzed for total metals, VOCs, SVOCs and PCBs identified in Title 6 of the New York Code of Rules and Regulations. (6 NYCRR) Part 373-2, Appendix 33. Soil and groundwater samples were analyzed by EPA test methods described in Test Methods for Evaluating. Solid Waste, Physical/Chemical Methods (SW-846).. Analytical Method 7471, cold-vapor atomic absorption, was used for-total mercury and Method 6010

.(inductively coupled plasma [ICP]-atomic absorption) and Method 602 (ICP-mass spectroscopy) was used for all other metal constituents. The soil and groundwater samples collected for chemical analysis were also analyzed for radiological indicator parameters including gross alpha, gross beta, and specific radionuclides based on the sample matrix (i.e., soil or groundwater).

The additional soil sample collected from location GP72-08 for geochemical characterization was analyzed for organic carbon and cation exchange capacity. In addition, a groundwater sample was collected and analyzed for general geochemical water quality parameters including alkalinity, total dissolved solids, total hardness, sulfate/sulfide, silica and selected dissolved metals from this boring.

The chemical, radiological and geochemical parameters analyzed for the soil and groundwater samples collected as part of this investigation are presented in Appendices B and C, respectively.

The contract required detection level (CRDL) to which these data were required to be reported during final lab subcontract negotiations are-also presented in these appendices.

2.6 Sample Location Survey On November 5, 2008, a New York State-licensed surveyor located and surveyed each sampling location for input into the existing site coordinate system. Vertical control was also established for the ground surface at~each soil boring location and referenced, to-the National Geodetic Vertical Datum of 1929 (mean sea level). The respective survey data for each soil boring location is included on the boring logs in Appendix A.

.3.0 PHYSICAL CONDITIONS 3.1 Topography, Land Usage, Drainage The WVDP ranges in elevation from 1,300 to about 1,445 feet above mean-sea-level. The undeveloped part of the larger WNYNSC that surrounds the WVDP remains a mixture of forest, wetlands and abandoned farmland.

The three named streams in the vicinity of the WVDP are Erdman Brook, Franks Creek, and Quarry Creek. The MPPB and related facilities are located on the north plateau (Figure 2).

3.2 Site Geology.

The subsurface conditions on the north plateau encountered during this investigation are characterized by a depositional sequence characteristic of an alluvial fan, consisting primarily of sand and gravel that overlies a deep sequence of till. The four stratigraphic units affecting the

WVDP-494 Rev. 0 Page 12 of 1158 transport of Sr-90 at the north plateau includes surficial fill material, the Thick Bedded Unit (TBU),

the Slack Water Sequence.(SWS), and the ULT. The TBU and SWS comprise the S&G unit on. the north plateau.

The ULT is predominantly an olive gray, silty clay glacial till with scattered lenses of silt and sand, and is considered to be unweatheredin the north plateau area. The till is reported to be a relatively impermeable aquitard underlying the S&G unit (WVNSCO, 1993). The till ranges in thickness from 40 feet (south of the MPPB area) to more than 100 feet (beneath the Construction and Demolition Debris Landfill [CDDL]). In the top of the ULT is a distinctive geologic unconformity with a southwest to northeast trending channel ending near Franks Creek. (WVNSCO, 1993). This channel in the ULT is filled with a layered sequence of well-sorted medium-to coarse-grained sediments that is identified as the SWS.

The SWS-is a meandering depositional sequence that filled in a topographic southwest to northeast trending channel in the ULT. It exists as an areally limited geologic.subunit about 190 to 600 feet in width and about 2,000 feet long with the narrowest width occurring less than 200 feet north of lagoon 5. It is composed-of four to six-inch-thick layers of. fine to coarse gravels and typically clean medium to coarse sands, separated by eight-to 18-inch-thick layers of brown silt and medium to fine brown sands that are dense and continuous. To the north, the SWS is truncated by the stream channel cut by Franks Creek. It thins and pinches, out both east and westalong the channel edge.

The SWS vanes in thickness from 0.to 15.feet. The thickest sequences are beneath the FIRS building and the narrow area west of lagoon 5. The SWS is differentiated from the overlying TBU primarily by its.interbedded stratigraphy.

The TBU is a poorly sorted, massive, silty sand and gravel layer that typically ranges from four to 15 feet thick;(with a maximum thickness of approximately. 25 feet identified during this investigation) and overlies the SWS and ULT. The thickest areas are south of the CDDL near the northern end of the plateau and where the SWS is present west of waste water treatment lagoons 4 and 5. The TBU extends to the north, west, and east edges of the. north~plateau where it is truncated by the stream valleys carved by.Franks Creek, Quarry Creek, and Erdman Brook, which has exposed the.

contact between the ULT and the TBU.

Above the.TBU is a discontinuous layer of fill ranging in thickness from 0 to 20 feet and locally spread across the north plateau, particularly near lagoons 4 and 5. This layer consists'of re-compacted silt and clay sediment generated during earlier site construction activities: The fill is generally above the water table.

A layer of fill, generally described as reworked sand and gravel, as well. as the SWS, TBU and ULT units were encountered at all boring locations, except for GP75-08 and GP108-08 where refusal.

.was encountered. The TBU ranged in thickness from approximately 6 feet (GP104-08, includes re-worked soil) to approximately 19.5 feet (GP109-08, includes re-worked soil). The. SWS ranged in thickness from two feet (GP102-08 and GP104-08) to 15 feet (GP29-08). The top of the ULT unit was encountered at depths ranging from 24 feet (GP1 04-08) to 41.5 feet (GP83-08) below the, ground surface.

4.0 SOIL DATA The implementation of the SAP resulted in 81 samples being collected at 18 locations (75 sample intervals plus six randomly collected field duplicates) during this characterization effort. Note that after analysis, GEL reported some data for parameters that were not specified in the SAP. All soil data provided by GEL are reported in Appendix D.. However, only analytical data identified in the SAP are evaluated in this report.

A description of the analytical results is presented. below. The soil sample locations are presented on Figure 3. Table 2 presents the site-specific soil screening levels (SSLs) for TAL metals. The determination of background soil concentrations and 'determination of SSLs is described inSection 4.1. Notable

WVDP-494 Rev. 0 Page'13 of 1158-analytical results are presented in Sections 4.2:1 and 4.2.2, and are shown in'greater detail in Tables 3 through 10. Data validation protocol for soils are discussed in Section 7.0.

4.1

-Determination of Background Metal Concentrations and Soil Screeninq Levels The determination of naturally occurring background metals concentrations.in north plateau soils at the site was conducted during a previous investigation. Background soil samples were collected for characterization in accordance with procedures outlined in Section 3.6.1(a)3 of NYSDEC's Division of Environmental Remediation document entitled, Draft DER-lO Technical Guidance for Site Investigation and Remediation (December 2002). The results of that investigation were reported in WVDP-493 North Plateau Background Soil Characterization Report (WVES, 2008).

Further.review of the.S&G.and ULT unit background metals data were performed in conjunction with this report. The S&G and ULT unit data sets appeared to be very similar in concentration ranges.. Therefore, an analysis of variance (ANOVA) between the background concentrations in the ULT as compared to the.S&G unit wasperformed for each metal.. Data sets from each geologic unit were compared using asingle-factor (one-way) ANOVA analysis. Thismethod was used totest whether the means from the two units could have been drawn from the same population, or whether they are sufficiently different that itwould be assumed they were taken from different populations. Appendix E-1, Table E-1 a summarizes the statistical data from both geologic units and Table E-1b provides the background metalsdata used to determine the mean concentrations for each unit. The acceptable error level was set at 0.05 or 95%. The statistical evaluation indicates that background TAL metals concentrations in soil are not statistically different in the two geologic units (see Appendix E-1, Tables E-lc and E-ld), except for calcium and magnesium.. These two metals are naturally occurring and variable concentrations are encountered within indigenous soils. Therefore, one background concentration that was applicable to both geologic units was identified for each metal.

To determine the background concentration for each metal, data from the five background borings (GPBG01-08 to GPBG05-08) plus borehole BH-38, advanced as a background soil location during RCRA Facility Investigation activities on the north plateau, were,-combined, regardless of geologic unit (see Appendix E); From this resultant background soil data set of 16.samples, a statistical analysis was performed as outlined in Section 3.6.2(a)1 of NYSCDEC Draft DER-10. The background data were transformed to natural logarithms and tested to identify outlier data. The identified outlier data were removed and the remaining data are presented in Table 2. This table presents the maximum metals concentrations in subsurface soil detected in samples collected from these six representative background sampling locations that were/are unaffected by site operations.

Included as a column in Table 2 are the TAGM 4046 soil cleanup objectives and cleanup levels for each metal. Using the site-specific background and the TAGM.4046 soil cleanup objectives, an SSL was identified for each metal by selecting, the higher of the two values. The SSL is used to evaluate the soil metals data generated during this sampling effort. It should be noted that the background concentrations established in this manner for antimony, silver, and thallium are below.

GEL's CRDL 4.2 Soil Analytical Results 4.2.1 Chemical Data Metals:

The SAP indicates that metals concentrations in soil would be compared to site background levels and/or'soil cleanup levels as presented in TAGM 4046. However, a TAGM 4046 soil cleanup level for mercury is specified and not tied to a site background concentration. Because mercury was not detected in soil samples above its soil cleanup level, it will not be discussed further in this section..

presented in Table. 3. The table also identifies the soil boring location, sample interval, and concentration. in milligrams per kilogram (mg/kg). These data were screened against the SSL.

Metals concentrations reported above their respective SSLs are presented in Table 4.

Samples in which metals concentrations. exceeded. SSLs were identified at 17 of the 18 boring locations. The boring location that did not have metals concentrations exceeding, SSLs was GP106-08. Concentrations above.the SSL are identified for 16 TAL metals at various depths ranging from four feet to 43 feet. In terms of decreasing frequency of

• .occurrence in individual samples, the metals reported above the respective SSLs included U

sodium, copper, magnesium, manganese, cadmium, arsenic, antimony, and. zinc.

Aluminum, beryllium, calcium, iron, lead, nickel, silver, and thallium were observed with one or two concentrations reported above respective SSLs. Antimony, silver, and thallium were identified at concentrations slightly above their respective SSL (i.e., theirsite-specific 3

background concentration); however, the site background concentrations established are lower thanthe CRDLs' for these metals. These data have been validatedas estimated concentrations. In addition, the concentrations of cadmium and zinc reported in characterization area soil samples were very slightly (i.e., highest concentration is 1.14 3

mg/kg for cadmium and 110 mg/kg for zinc), above their respective SSLs of 1 mg/kg (i.e.,

TAGM 4046 soil cleanup level)-and 99.7. mg/kg (i.e., site background).

In duplicate sample GP30-08, collected from. the four-to six-foot depth, antimony.(2.79 mg/kg estimated), arsenic (.13.1 mg/kg), and calcium (67,800 mg/kg) were detected slightly above their respective SSLs of 2.28 mg/kg (estimated), 12.5 mg/kg, and 57,600 mg/kg, but were not reported above the SSLs in the original sample. In.duplicate sample GP80-08 (25-27 feet), copper was detected at 34.4 mg/kg, which is slightly above its SSL of 30 mg/kg, but was not reported above the SSL in the original sample. These data indicate that

~the above-referenced analytes exhibit'some level of heterogeneity within site* soils...

The original metals results for the soil sample collected from boring GP72-08 (34-36 feet). *

!. 1 indicated the presence of elevated levels of lead'(135 mg/kg as compared to 30.9 mg/kg site background) and' arsenic (65.4 mg/kg as compared to 12.5 mg/kg site background).

GEL's original quality control (QC) duplicate analyses for lead and arsenic on this sample reported concentrations of 12.5 mg/kgland 10.6-mg/kg, respectively. A lab QC note, indicated sample heterogeneity issues due to sample matrix. A separate aliquot of this soil sample was reanalyzed and lead and arsenic concentrations were reported at 10.2 mg/kg and 9.5 mg/kg, respectively. Duplicate lab QC samples also indicated concentrations of I

lead and.arsenic at 17.9mg/kg and 11.1 mg/kg, respectively. There were no data quality issues indicated by data validation review-on these results other than heterogeneity issues.

Because these original analyses and re-analyses (including QC samples) were done on.

different portions of the sample, these results indicate there is significant heterogeneity I

within. the soil sample. In summary, three'of four analytical runs for lead and arsenic yielded results below, site background levels and thus the original analytical, results would

" not appear to be associated.with chemical contamination, which would be anticipated to be I

less affected by soil heterogeneity within a discrete sample horizon.

Additionally, the metals results for soil.sample GP76 (24-26).feet indicated the presence of elevated levels of magnesium (82,600 mg/kg) as compared to 10,900 mg/kg foe its'SSL. Arsenic (113 mg/kg) was reported above its SSL (12.5 mg/kg).in soil sample GP1 05-08 (34-36 feet). These data may be related'to soil heterogeneity, as discussed above.

WVDP-494 Rev. 0 Page 15 of 1158 concentrations (i.e., less than their CRDL) as presented. in the above discussion, or 3) naturally occurring metals calcium, magnesium, potassium, and sodium.

Table 5 presents the analytical data for the metals reported above the SSL from historical samples that were collected within the north plateau plume area. Figure 6 presents the historical soil and groundwater sampling locations within the plume area. Multiple detections were reported for antimony, arsenic, and thallium above their SSL. In addition, two detections each-of magnesium, manganese, and zinc, as well as single detections of aluminum, calcium, lead, and potassium were reported above their respective SSLs.

Reported concentrations of arsenic and antimony generally are' slightly above their respective SSLs with variability likely the result of sample heterogeneity, as previously discussed. Additionally, the vast majority of the antimony results were validated as being estimated concentrations. The analytical results for aluminum, manganese, calcium, potassium, thallium, and zinc were validated as estimated concentrations and are in nearly all cases only slightly abovetheir SSLs. Sodium, potassium, calcium, and magnesium are naturally-occurring.metals generally present at or near background concentrations in site soils.

On the basis of the S&G and ULT metals data, much of the plume characterization data appeared to be comparable to site background data. To determine if the overall data sets are comparable,.the total metals concentrations from subsurface soil samples collected at the 18 characterization borings and analytical data from 1993 and 1998 soil sampling performed in the north plateau plume area were statistically compared with the background sample dataset (Appendix E-2) using the single-factor (one-way). ANOVA technique. As previously stated in Section 4.1, this method can be used to test whether the means from the two groups (plume area data and background data) could have been drawn from the same population, or whether they are sufficiently different that it must be assumed that they were sampled from different populations. Appendix E-2, Table E-2a summarizes the background and characterization area (including the downgradient plume area for those metals reported above the SSL) metals data used to determine the mean concentrations for each soil unit. The acceptable error level was set at 0.05 or 95%. The statistical evaluation (Table E-2b) indicates that TAL metals concentrations in soil did not exceed the background soil data set for any of the metals evaluated. Therefore, it is concluded that, even though the highest background value may be exceeded by an individual characterization area sample, the total metals concentrations for the characterization area, as a group, were not significantly higher than the background data set, as a group.

In summary, the 2008 metals characterization data indicate that the reported exceedances may or may not be actual exceedances based on their detections being below their respective CRDLs, the heterogeneity of the'site soils, and. the ANOVA results indicating that the characterization and background soil data sets are comprisedof comparable concentrations. The concentrations of antimony, silver, and thallium are generally estimated and along with'cadmium and zinc were reported in characterization area soil samples at concentrations very slightly above their'respective SSLs. Figure 5 presents the SSL exceedances for metals data, excluding calcium, magnesium, potassium and sodium that are naturally occurring' In addition, -there are soils concentrations for aluminum, arsenic, beryllium, copper, iron, magnesium, manganese, and nickel, and one historical soil sample concentration for, lead. that are very close to their SSLs.

Overall, much of the analytical data collected during this characterization is very close to the reported site-specific background concentrations. The resulting metals data indicates very random and sporadic concentrations of metals at various depths across the characterization area. There appears to be no cause for the spatial variability of the subsurface metals data in soil other than the heterogeneity of the local soils. TAL metals occur in nature and their concentration in the background soil will exhibit considerable

.variability, both stratigraphically and spatially. This variability is related tothe variable

To conclude, the distribution of metals does not follow a concentration gradient indicative of a discharge from under the MPPB.

Organic Chemicals:

The VOCs detected in the soil samples are summarized in Table 6. Thirteen VOCs were detected above the laboratory method detection limit (MDL) atall 18 sampling locationsat I

concentrations ranging from 75.4 micrograms per kilogram (pg/kg) of toluene in a duplicate sample (the original sample was reported at 4.74 pg/kg) to an estimated 0.236 pg/kg of ethyl benzene.: However, there were no VOCs reported above their respective TAGM 4046 soil cleanup level.

U

• The SVOCs detected in the soil samples are summarized in Table 7. Eighteen SVOCs Were detected above the laboratory's MDL at 13 sampling locations. The SVOC concentrations detected ranged from 2.25 mg/kg of butylbenzylphthalate in sample GP109-08 (36-38 feet) to a concentration of 0.011 mg/kg (estimated) for fluoranthene in GP30-08 at a depth of 15 feet. to 17.feet. Benzo(a)pyrene was the only SVOC reported above its TAGM 4046 soil cleanup-level (i.e., 0.061 mg/kg) in soil samples from borings GP72-08, GP76-08, GP101-08, and GP108:08 at multiple depthsin the TBU, with a maximum.

reported estimated concentration of 0.257 mg/kg (the four results were below the CRDL and are considered estimated values).

3 The PCBs detected in the soil samples are presented in Table 8. Five PCB isomers in eight soil borings Were detectedabove the laboratory's MDL, at concentrations up to 0.0873 mg/kg (boring GP105-08). However, there were no PCBs reported above the TAGM 4046 soil cleanup level.

In conclusion, soil sample results for the organic chemicals suggest that there is no organic component associated with the Sr-90 plume source.

4.2.2 Radiological Data.

Each of the 81 samples collected for chemical analyses were also tested for 19 radiological parameters. Radiological data from the 18 soil borings advanced as part of this investigation are summarized in Tables 9 and Table 10. Complete results of radiological analyses in soils are presented in Appendix D, Table D-5..

In Table 9, the range of observed concentrations of the radiological constituents in the 2008 soil samples is presented with the location and depth interval of maximum concentration. Alltarget isotopes were detected in at least one sample, except for carbon-

.14. As expected, Sr-90. exhibited the highest radiological concentrations. Gross beta andI six of the radioisotope maxima were observed at boring GP76-08 inside. the MPPB in the RER. Three of these concentrations (gross beta, Sr-90.and technetium-99) were observed at a depth of 15 feet to 17 feet. The remaining four maxima (cesium-1 37, plutonium-238, 3

plutonium-239/240, and americium-241) were observed at the 19-to 21-foot depth interval.

..Table 10 shows a comparison of maximum radiological concentrations over time in soil by depth and location. Maximum nuclide concentrations observed during the 1994 and 1998

• Geoprobe sampling campaigns are included with the. maximum concentrations of the 2008 sampling effort. Although it Would appear from the'data presented in Table 10 that the radioisotope concentrations increased in 2008, in many cases the higher maxima areI an artifact of the increased number of samples collected inthe source area in 2008, as wellI as to variability in the depths sampled. It is difficult to make a comparison between historical results because there are only a few direct one-to-one correlations between II

. Figure 7for soil. For example, Figure 7 indicates that equivalent soil samples can only

As described in the SAP, one of the primary reasons for isotopic analysis was to determine if a correlation existed between elevated metals concentrations, if encountered, and

.radiological concentrations. As evaluated in Section 4.2.1,. themetals concentrations for

'.the characterization area, as a group, were not statistically higher than the background

• data set. Metals data indicates sporadic and random concentrations, many at or near background soil concentration levels, at various locations and depths, which are not consistent with Sr-90 being present at all borings locations~and depths sampled..

Therefor'e, evaluation of a correlation between the sporadic elevated metals data and the radiological data is not warranted. However, looking at the reverse correlation, soil.

radionuclide maxima were detected more frequently at GP76-08, but metals concentrations above the SSLs were not prevalent at this location.

5.0 GROUNDWATER DATA The implementation of the SAP. resulted in 42 groundwater samples being collected from various depth intervals sampled at 16 of the proposed 18 boring locations. All groundwater samples were collected in the S&G unit. Groundwater samples were. not collected at GP75708 and GP108-08 due to refusal being encountered above the water table at those locations. Also, groundwater samples were collected from the 12 wells sampled during the 2005 metals investigation, as well as in June 2007, September 2007, December 2007, September 2008 (concurrent with this investigation) and November 2008.

Prior to sample collection, the open:soil borehole was purged of a minimum of three borehole volumes or to

-dryness using a peristaltic pump to ensure that the sample being collected was representative of groundwater at the depth interval being sampled. The groundwater samples collected exhibited turbidity (i.e., suspended soil particles) from the open boreholes and were not filtered prior to analysis of chemical parameters.

It should be noted that direct-push (i.e., Geoprobe) boreholes possess very different characteristics than conventional monitoring wells, and therefore groundwater samples collected from open boreholes tend to be turbid. Because of the sampling methodology, groundwater samples collected from Geoprobe boreholes are of relatively higher turbidity compared to turbidity levels in groundwater samples collected from standard monitoring wells, especially when collected from fine-grained formations. Turbidity is a particular concern because metal cations readily adsorb to suspended silt and clay particles via electrostatic charges (Barcelona, 1990;. Hem, 1989). The surficial negative charge of the colloids and impurities attracts and typically binds the positively charged metal cations in groundwater (EPA 2005).

A description of the analytical results is presented below. The sample locations are depicted on*Figure 3.

Notable analytical results are presented in*Sections 5.2.1 and 5.2.2, and are shown in greater detail in Tables 11 through 22. A complete listing of all analytical results in groundwater is included in Appendix F.

Data validation procedures are discussed in Section:7.0...

5.1 Determination of Back-round Metal Concentrations and Groundwater Screeningi Levels The determination'of naturally occurring background metals concentrations in: site groundwater was completed by determining the upper 95% confidence limitfor of 'each -of the Appendix 33 list metal constituents analyzed for in groundwater samples collected at existing background wells 301, 401, 706, and 1302 (using data collected from 1991 to 2008) in the S&G unit on the north plateau.

Groundwater samples from these routinely monitored wells are not filtered prior to metals analysis.

Elevated chromium. and nickel concentrations attributed to corrosion of the stainless-steel

WVDP-494 Rev. 0 Page18 of 1158 monitoring wells (i.e., 301, 401, and 706) were excluded from determining the upper 95%

confidence limit for these analytes. The range of observed metals concentrations and the calculated *upper 95% background, groundwater metals concentrations, (upper 95% limit) are shown in Table 11..

Using the groundwater background concentrations and the TOGS 1.1.1 water qualitystandards, a I

set of site-specific groundwater screening levels (GSLs) for metals were determined, as presented in*Table 11. Each GSL was determined by taking the higher of the background groundwater concentration or the TOGS 1.1.1 water quality standard. These GSLS are used to evaluate the:

groundwater metals data generated during this field effort. The metals groundwater data collected from the 2008 Geoprobe sampling program are presented in Table.12, along with the groundwater background concentrations and. TOGS 1.1.1 water quality standards..

It is worth noting that groundwater background concentrations for antimony, cadmium, chromium, lead, selenium, and thallium exceed their respective TOGS 1.1'.1 water quality standards. The WNYNSC is in a rural 'area that has not been industrially developedother than the WVDP portion of this property. There would be no reason to have these higher concentrations of metals in groundwater in the areas identified as background areason the site other than they are associated with the in-situ soils common to the north plateau area.

Metals detected in the 2008 Geoprobe groundwater samples at concentrations above their respective GSLs are-presented in Table 13. Appendix 33 list metals in the groundwater samples exceeded GSLs at 11 of the 18 sampling locations.. Concentrations exceeding GSLs were'reported at depths ranging from 14 feet (i.e., near the top of the saturated zone) to 41 feet, very close to the bottom of the S&G unit. In terms of frequency

.of individual analytes exceeding GSLs, arsenic, chromium, lead,' vanadium, nickel, barium, beryllium, and copper were detected at concentrations above GSLs most frequently. It is worth noting that arsenic, beryllium, chromium, copper, iron, nickel, and zinc were detected' in background soil samples at concentrations thatexceeded the numerically-specified soil cleanup levels in TAGM 4046 (e.g.,'arsenic soil cleanup levels referenced as 7.5 mg/kg or soil background, whereas the site-specific soil background was determined to be 12.5 I

mg/kg). This suggests that these metals could be present in site groundwater at elevated

• .levels that reflect in-situ soil conditions:

The metals detected in groundwater above background appear to be somewhat randomly distributed as shown on Figure 8. Two individual samples.(GP72-08 collected from 38 to 40 feet and GP107-08 collected from 15-17 feet) generally* have the maximum observed metals concentrations for nearly all the metals that were analyzed. Groundwater samples collected from borings GP101-08, GP102-08, and GP104-08 did not exceed GSLs for any Appendix 33 List metals. Since no pattern is observed of.similar concentrations with'depth or in the nearby wells, these metal concentrations may be due to these two samples.

having more turbidity than the other samples, or be attributable to soil heterogeneity, as I

previously discussed in Section 4.2.1.

WVDP-494 Rev. 0 Page 19of 1158*

'To betterevaluate the groundwater data generated from the Geoprobe borings, it may be relevant to screen out the background metal concentrations presented in Table 11 to account for the.'bias" resulting from either 1) the open borehole sampling technique to assess potential turbidity issues and/or 2) the elevated levels of background metals noted in the upgradient or background wells. After subtracting out the background

concentrations (Table 11) from the concentrations reported above GSLs (Table 13), the data can be compared to the TOGS 1:1*.1 water quality standards to determine if therermay

-be a trend in the groundwater data (see Table 14).. The result of this screening. is.

" presented on Figure 9, which would show that the total number of reported exceedances presented in Table 13 would be reduced (i.e., screened down).to 26,exceedances (approximately one-third the number of exceedances shown in Table 13). Additionally, 1.5 of.the 26 exceedances would be associated with samples.GP72-08 (38-40 feet) and GP107-08 (15-17 feet)., Samples GP30-08 (35-3.7 feet) and GP109-08 (28-:30 feet) would exhibit three detections; sample GP80-08 (39-41 feet)'would exhibit two detections; and samples GP29-08 (35-37 feet) and GP106-08 (20-22 feet) would exhibit one detection.

This information, as presented on Figure 8, shows that GP72-08 and GP107-08 exhibit the highest metals concentrations 'and there is minimal data to infer the presence of metals at elevated concentrations between these boring locations. In addition, as presented in Section 4.2.1, much of the soil analytical data collected.during this characterization is very close.to the reported SSLs and does not support the presence of a source area of metals capable of releasing metals constituents to groundwater.

Appendix 33 List metals detected above background during special groundwater monitoring well sampling events in 2005, 2007, and 2008. are shown in Table 15. Fourteen metals were detected in the unfiltered samples above their corresponding GSLs in six wells and two well points. The overwhelming majority of metals detected above GSLs-were.

observed in the deep (WP20D)and shallow (WP20S) Well point pair. Each is a flush-mounted well pointthat was installed within a 2.25-inch-diameter Geoprobe borehole using one-inch-inside-diameter, Schedule 40 polyvinyl chloride well screen and riser. The:

wells screens are 0.010-i nch slot and three-foot long.. The sand pack extends from one foot below the well screen to one foot above the well screen. The remaining annular space between the well screen and the borehole is approximately 0:9 inches, which does not allow for an adequate-sandpack thickness to effectively filter fine grained.soil such as those that are present at the WVDP. Of~the exceedances listed in Table 15, wells 104, 301,408 and 502 have several exceedances of nickel and chromium above the GSL. These wells are stainless steel and corrosion of the well screens, as documented for the site in Final Report: Evaluation of the Pilot Program to Investigate Chromium and Nickel Concentrations in Groundwater in the Sand and Gravel Unit (WVNSCO and Dames &

..Moore, 1,998) may result in the. reported concentrations of these metals. Periodically, environmental sampling personnel will scrub the interior well.screens of stainless-steel wells to remove ingrowth contributing to.the higher levels of chromium and nickel..The wells are purged afterwards and subsequent analytical data for chromium and nickel[

typically result in lower concentrations reported.

Chromium was detected once in well NP01-27 (June 2007) and twice in NPO1-29 (June and.September 2007) above the GSL. The remaining metals detections above the GSLs" were reported in well points WP20S and WP20D. These.data have been. previously (flush-mount and sandpack.thickness) and the infiltration of surface water into the monitoring points. Therefore, replacement wells (standard construction).are planned for installation in calendar.year 2009 to provide more meaningful data from the area south of the.FRS.

The historical groundwater data reported for WP20S and WP20D show that there are more.

reported concentrations for more analytes above GSLs for WP20S than there are for

I WVDP-494 Rev. 0 Page.20 of 1158 WP20D. This pattern was not observed in groundwater sampling performed borings GP30-08 and GP72-08, which are within approximately 50 feet of these piezometers.

Table 16 presents the historical (i.e., pre-2005) analytical data for the Appendix 33 metals reported above their respective GSLs that were collected from groundwater monitoring points within the north plateau plume area. Between the special metals sampling (Table

15) and prior historical metals sampling (Table 16) a total of 10 wells and two well points (see Figure.6).were identified with exceedances of the GSL for.14 metals. The greatest number of metals detections above GSLs occurs for chromium and nickel. The chromium exceedances were reported in nine stainless-steel wells (i.e., 105, 106, 115, 116, 408, 501, 502, 802, and 804), two PVC wells (NP01-27 and NP01-29), and.two PVC well points.

(WP20S and 20D). The nickel exceedances were reported in six stainless-steel wells (i.e.,

106, 116, 408,1501, 502, and 804) and well points WP20S and 200. The stainless-steel wells listed above have been identified as exhibiting well screen corrosion, which is documented to result in increased concentrations of these metals. As shown in Table 15, elevated levels of beryllium, cobalt, copper, selenium, silver, vanadium, and zinc were only reported in piezometers WP20S and WP20D. Wells NP01-27 (chromium), NP01-29 (chromium), 105 (arsenic), 115 (lead), 802 (barium), and 8604 (antimony) were reported With only one metal exceeding its respective GSL.

In conclusion, the distribution.of metals in groundwater samples does not appear to be indicative of a release from a source area under the MPPB.

Orqanic Chemicals:

The VOCs detected in the 2008 groundwater samples are summarized in Table 1.7. Six VOCs were detected above the laboratory MDL at the 16 Geoprobe locations sampled for groundwater; however, there were no VOCs concentrations reported above their TOGS

.1.1.1 groundwater quality standards.

The SVOCs detected in the 2008 groundwater samples are summarized in Table 18. Two SVOCs were detected above the laboratory's MDL. Of these, only p-Nitroaniline was reported in groundwater samples at.estimated concentrations of 5.09micrograms per liter (pg/L) and 5.29 pg/L, which slightly exceed its TOGS 1:1.1 water quality standard of 5.0 pg/L.

There was only one PCB isomer, Arochlor-1254, detected in the groundwater at two locations as presented in Table 19. Arochlor-1254 was reportedat estimated concentrations of 0.18 pg/L and 0.14 pg/L at GP72-08 (20-22 feet) and.GP103-08 (21-23 I

feet), respectively. Although these. detections were*also below the CRDL for Arochlor-.

.1254, they were above the associated TOGS 1.1.1 water quality standard of 0.09 pg/L.

In conclusion, groundwater sample results for organic chemicals in the characterization area suggest that they are not associated with the Sr-90 plume source.

5.2.2 Radiological Data After field-filtering, the groundwater samples were tested by GEL for 21 radiological constituents. Complete results of radiological analyses in groundwater are presented in

, Table F-5 of Appendix F. Radiological data for the groundwater samples from the 16 Geoprobe locations sampled for groundwater are summarized in Tables 20 and 21.

The locations and depth intervals of maximum groundwater concentrations of the two radiological indicator parameters (gross alpha and gross beta) and the.19 radioisotopes are indicated in'Table 20. All of the target isotopes were detected in at least one sample, except europium-154. Gross beta and eight of the isotopic maxima were observed at

....I

WVDP-494 Rev. 0 Page 21 of 1158 GP76-08 inside the.MPPB in the RER. Most of the maxima at this location were observed "at the 20- to 22-foot interval.,The majority of the isotopes are consistent with the soil maxima also observed at GP76-08. As expected, Sr-90 showed the highest isotopic concentration.

_A historical comparison of maximum radiological concentrations in groundwater observed in 1994, 1998, and 2008 Geoprobe points on the north plateau is shown in Table 21 and on Figure 10. Data in the table show that radioactivity;levels in groundwater have generally decreased since 1994; Where the maxima increased since 1994, the result may, in part, be related to the increased number of groundwater samples collected in the source.

area: during the 2008 Geoprobe sampling campaign, compared to other individual.

groundwater monitoring episodes. As previously noted, it is difficult to make a comparison between historical results because there are only a few direct one-to-one correlations between corresponding depths sampled at.the same sample locations from 1994 to 1998 as illustrated on Figure 10 for groundwater. For example, Figure 10 shows that direct groundwater comparisons can only be made at GP29-08 from 17 tol9 feetand 29 to 31 feet, GP30-08 from.20 to*22 feet, GP78-08 from 19 to 21 feet and GP80-08 from 32 to 34 feet. In all five instances there is no comparable 1994 groundwater sample at the equivalent depth. A third variable is that equivalent analyses were not run on all samples.

As expected,the maximum radionuclide concentrations observed. in groundwater samples collected Were for Sr-90,-except for tritium at GP102-08. Table 22 presents the maximum radionuclideconcentration for each groundwater sample collected in a soil boringl In general,.the higher Sr-90 concentrations are observed in the TBU south of the FRS, as well as in the SWS north of the FRS. The highest concentration (733,000 pCi/L) was

..reported in the RER (i.e., GP76-08). GP101-08 located near the northwest corner of the FRS, was reported with a maximum Sr-90 concentration of 325.pCi/L.

As with. the soils, one of the primary reasons for isotopic analysis was to determine if a correlation existed between elevated metals concentrations in groundwater, if encountered, and radiological concentrations. No background radiological evaluation has been performed for the'site to date; therefore, a correlation between elevated metals'and radiological constituent concentrations can not be performedl However, looking at the reverse correlationj groundwater radionuclide maxima were detected more frequently at GP76&-08, butimetals concentrations above the GSLs were.not prevalent at this location, as was the case for soils.

6.0 GEOCHEMICAL DATA The dissolved metal and non-metal parameters analyzed for in the Geoprobe GP72-08 soil and groundwater geochemical evaluation are presented in Table 23 for potential future use in the design of a subsurface permeable reactive treatment wall.

7.0 DATA VALIDATION All analytical data packages were validated by WSMS personnel, in accordance with procedures.EM-68, EM-67, and EM-74, plus administrative validation procedure EM-108. The data Validation process included review of laboratory data documentation as follows: *

, completeness; holding time compliance; QC data (blank, surrogates, recoveries, laboratory controls, etc.); and data qualifier assessment.*"

The data validation reports addressing the soils analyses are shown in Appendix H. The data validation reports addressing the groundwater analyses are shown in AppendixI.

SUMMARY

AND CONCLUSIONS 8.1 Chemical Data 8.1.1 Soils Much of the plume area data appeared to be comparable, in terms of total metals concentrations, to site background data; therefore, an ANOVA analysis was performed to test whether the means from the two groups (plume area data and background data) could have been drawn from the same population. Results of the statistical evaluation indicate that plume area metals concentrations in soil did not exceed the background soil data set for any of the metals evaluated. Therefore, it is concluded that the total metals concentrations for the characterization area, as a group, were not significantly higher than the background data set, as a group.

Considering the overall distribution of metals detected above the SSLs, exceedances are random and sporadic at varying depths across the characterization area. The cause for the spatial variability appears to be heterogeneity and geochemical characteristics of the local soils.

No VOCs or PCBs were detected above TAGM 4046 soil cleanup levels. Only one SVOC, benzo(a)pyrene, was reported above its TAGM 4046 soil cleanup level (i.e., 0.061 mg/kg) in soil samples from four soil borings at depths ranging from four to 14 feet.

To conclude, the distribution of metals and organic chemicals in the north plateau plume subsurface soils is random and does not follow a concentration gradient indicative of a discharge from the Sr-90 plume source areas.

I 8.1.2 Groundwater The metals detected in groundwater from the Geoprobe boreholes advanced during this I

investigation at concentrations above background appear to be somewhat randomly

• distributed (Figure 8). Two individual samples, GP72-08 (38-40 feet) and GP107-08 (15-17 feet), generally have the maximum observed metals concentrations for nearly all the

• metals that were analyzed. Since no pattern is observed of similar concentrations with I

depth or in the nearby wells, including wells existing between these two locations, these elevated metal concentrations may be due to.these two samples having greater suspended sediments than the other samples, and/or attributable to soil heterogeneity.

3 Fourteen Appendix 33 List metals were detected above GSLs in eight well points during special groundwater monitoring well sampling events in 2005, 2007, and 2008. The overwhelming majority of metals detected above GSLs were observed in well points WP20S and WP20D. Theseweli points are to be replaced with standard monitoring wells in calendar 2009, due to elevated turbidity, levels in groundwater samples collected and documented inflow from surface water runoff intothe well points.

From historical monitoring within the north plateau plume area, seven Appendix 33 List metals have been reported above the GSL from groundwater samples collected in 10 wells. The greatest number of metals detections above GSLs occurs for chromium and nickel, with these detections primarily associated with wells having stainless-steel well I

screens, and exhibiting well screen corrosion. This results in increased concentrations of these metals. Scrubbing of the well screen interiors has resulted'in chromium and nickel being reported at lower concentrationsfor a limited period following the well maintenance activities. In general, isolated detections of antimony, arsenic, barium, cadmium, chromium, and lead were reported only slightly above the respective GSL for the remaining wells, except for well points WP20S and WP20D.

WVDP-494 Rev. 0 Page 23 of 1158 When looking at the overall distribution of metals detected above the GSLs, detections are random and sporadic at varying depths across the characterization area. The cause for the spatial variability appears to be the heterogeneity and characteristics of local -soils and in some cases (e.g., chromium and nickel), well construction materials. In.addition, the exceedances of SSLs in Geoprobe soil-samples do not appear to correspond with groundwater exceedances of GSLs; except at soil borings GP72-08 and GP107-08.

No VOCs were reported at concentrations above their TOGS.1.1.1 groundwater quality standards. The SVOC p-Nitroaniline was reported in groundwater samples at estimated concentrations of 5.09 pg/L and 5.29 pg/L, which slightly exceedits TOGS 1.1.1 water quality standard of 5:0 pg/L. One PCB isomer, Arochlor-1254, was detected at estimated, concentrations of 0.18 pg/L and 0.14 pg/L, which were reported above the TOGS 1.1.1 water quality standard of 0.09 pg/L.

To conclude, thedistribution of metals and organic chemicals in tWe north plateau groundwater is generally sporadic and random and does not follow a concentration gradient indicative of a discharge from the St-90 plume source areas.

8.2 Radiological Data 8.2.1 Soil All target isotopes were detected in at least one sample, except for carbon-14. As expected, Srr90 exhibited the highest:radiological concentrations. Grossbeta and six of the radioisotope maxima were observed at boring GP76-08 inside the MPPB in the RER.

Three of these concentrations (gross beta, Sr-90 and technetium-99) were observed at a.

depth of 15 feet to 17 feet. The remaining four. maxima (cesium-137, plutonium-238, plutonium-239/240, and americium-241) were observed atthe 19-to 21-foot-depth interval..

Based on data presented in Table 10, it would appear that the radioisotope concentrations increased in 2008; however, in many cases the higher maxima are an artifact of the increased number of samples collected in the source area, as well as to the variability in the depths sampled. It is difficult to make a comparison between historical results because there are only a few direct one-to-one correlations between corresponding depths sampled at the sample locations from 1994 to 1998..

• "There is no apparent correlation between "elevated" metals concentrations and radiological concentrations in soil.

8.2.2 Groundwater All of the target isotopes were detected in at least one sample, except europium-154. The highest gross beta concentration and nine of the isotopic maxima were observed at GP76-08 inside the MPPB in the RER. Most of the maxima at this location were observed at the 20- to 22-foot interval. As expected, Sr-90 showed the highest isotopic concentration.

Comparison of the 2008 Geoprobe groundwater data to the historical Geoprobe groundwater results indicates that there are only a few'direct one-to-one correlations between corresponding depths sampled at the sample locations from 1994 to 1998.

During the previous investigations, Sr-90 and cesium-137 typically exhibited the highest

• isotope concentrations in groundwater and these radioisotopes still exhibited the highest

..concentrations. during this investigation: A historical comparison of radiological parameters in groundwater at 12 groundwater monitoring locations at various times shows, that radioactivity in groundwater in the study area has generally decreased since 1994.

All samples from the 18 plume area characterization Geoprobes are included in this determination of range of concentrations:

Analysis for U-232 and Pu-238 were not specified in the SAP, however they are included in the radiological analyte list because they are site-specific to the WVDP and are typically included in WVDP sample analysis requests.

c One result is typically reported for U-233/234, U-235/236, Pu-239/240" and Cm-243/244 because the peaks for each radionuclide are difficult to differentiate from each other during analysis.

WVDP-494 Rev. 0 Page 534 of 1158 Appendix E Statistical Evaluations of Background and Characterization Data for Total Metals in Subsurface Soil and Groundwater This Appendix includes three sections pertaining to total metals in background subsurface soil and groundwater on the north plateau at.the West Valley Demonstration Project:

Appendix E-A: Background Metals Concentrations in Soil This appendix provides several analyses of the metals data-in soil including:

o Statistical analysis of the data that demonstrates why it is appropriate to combine the Sand and Gravel (S&G) and Unweathered Lavery Till (ULT) background metals data t6developone background concentration for each metal to use for evaluation of both geologic units. This is done using an analysis of vanance (ANOVA) to compare the metals data sets from S&G and the ULT background samples; and o

Supporting data for establishment of site-specific soil screening levels (SSLs) for metals presented inTable 2 of this report.

Appendix E-2: Statistical Comparison of Characterization and Background Soil Metals Data Sets A statistical evaluation is provided in this appendix using the analysis of variance (ANOVA) method to compare total metals data from the 18 plume area soil borings advanced in 2008, as well as historical soildata collected within the plume area with the data from the 6 background soil borings tabulated in Appendix B-1.

Appendix E-3: Determination of Background Metals Concentrations In Groundwater A description of the groundwater background calculations used to establish the background groundwater concentrations using a 95% limit (i.e., mean plus two standard deviations).

Background Metals Concentrations in Soil

WVDP-494 Rev. 0 Page 536 of 1158 Appendix E-A: Background Metals in Soil Data from six subsurface soil locations on the north plateau of the WVDP were used to calculate total metals backgrounds for comparison with results from subsurface soil'in downgradient locations: Of the six locations, five were sampled in 2008 as part of the Geoprobe north plateau charactenzation program. The other location was onenorth plateau background borehole (BH-38) that had been sampled in 1993 as part of the Resource Conservation and Recovery Act Facility Investigation (RFI) program (WVDP-EIS-008). Data from the six locations were divided into two groups according to the geological. unit from.which the samples were taken (S&G or ULT).

Locations'and depths at which background subsurface soil samples had been collected are shown in WVDP-493, Figure 3.

Ten data points were available for total metals in the S&G unit and six in the ULT. At one ULT sampling point a duplicate set of samples was collected. The maxima for each geologic unit separately and for the units combined are shown in Table E-1la. The full set of data used for establishing the background metals concentrations in soil for the north plateau is shown in Table E-1b. Duplicate results were notaveraged.prior to:determination of-the maximum measurements.

The maximum background metals concentrations for the combined geologic units, as highlighted in the table below, were used to develop the SSLs shown in Table 2 of this report. The.SSLs were compared with individual measurements'on the samples collected from the 18 characterization Geoprobesfor the West Valley Demonstration Project North Plateau Plume Characterization Report (WVDP-494).

Statistical Comparison of S&G and ULT Background Metals Concentrations in Soil Statistical analysis of the background data using ANOVA demonstrates why it is appropriate to combine the S&G and ULT background metals data to develop one background concentration for each, metal to use for evaluation of both geologic units.

Data sets from each geologic group (S&G vs. ULT) were compared using a single-factor. (one-way) ANOVA method* This method was used to test whether the means from the two groups (S&G and ULT) could have been drawn from the same population, or whether they are so different that we must assume they were taken from.

different populations. Table E-1c summarizes the results of'the statistical analysis. Documentation of the ANOVA calculations is provided in Table E-1d., The following paragraphs describe the ANOVA analysis of the S&G and ULT soil background metals datasets.

Ten data points were available for total metals in the S&G unit and six in the ULT. At one ULT sampling point a duplicate set of samples was collected. In accordance with the applicable procedure established for deriving statistical averages, data from the duplicates were averaged and treated as a single sample. Frequency distributions from select-data sets were plotted to confirm that values approximated a normal distribution,.an underlying assumption for the. ANOVA statistical test.

The null hypothesis being tested was that the two means were statistically different (a "two-tailed" hypothesis, since it did not matter in which direction the means differed). The acceptable error~level was set at P<0.05 (i.e., a level of confidence of 95%). The single-factor ANOVA function of Microsoft Excel was used to run.a single test for each metal. The critical Value for the test statistic "F" and the".F"' value for the groups being evaluated were. calculated as part of the Excele function. Results are summarized in Table E-lc. To interpret the results of each test:

(1)

If the test statistic "F" was greater than the critical value of "F," then the null hypothesis was accepted (that is, the means were assumed to be statistically different),.

(2)

If the test statistic "F" was less than the critical value of "F," then the null hypothesis was rejected (that is, the means were assumed to be statistically the same).'

Conclusions:==

For 21'of the 23 Target Analyte List (TAL) metals in soil, results from the S&G and the ULT units were determined not to be significantly different.. Results for total calcium and total magnesium, however, were

WVDP-494 Rev. 0 Page 537 of 1158 significantly different between the two units. Averages for both metals were higher in the ULT. However, these two metals are naturally occurring and not contaminants of concern for this investigation.

Therefore, because the background concentrations of contaminants of concern from the S&G and the ULT were determined not tobe statistically different, it was decided tocombine results from the two unitsto produce asingle background subsurface soil value for each metal. This also provides for simplicity in evaluating concentrations of these contaminants in downgradient samples.

WVDP-494 Rev. 0 Page 556 of 1158

'Appendix E-2 Statistical Comparison of.Characterization and Background Soil Metals Data Sets In the text and figures of the this. report (West Valley Demonstration Project North Plateau Plume Characterization Report (WVDP-494)), individual total metals results from north plateau characterization samples (from the.18, borings drilled to characterize the subsurface underneath and immediately downgradient of the Main Plant Process Building) and from historical borings were compared with SSLs, set equal to the higher of (1) the maximum value S

• noted in the background samples, or (2) the New York State Department of Environmental Conservation's Technical Administrative Guidance Memorandum (TAGM) guidance value. (See Table2 of this report and Appendix E-1.) In several instances, downgradient metals in soil exceeded the SSL (see Table 46of this report). To further evaluate the significance of these exceedances, a statistical analysis was done to compare the data sets from each sample group asa whole(characterization samples vs. background samples).

Total metals concentrations, (in mglkg).from 81 subsurface soil north plateau characterization samples (81 for calcium and potassium).(from the GP29-08 to GP.109-08 borings) were combinedwith similar results from historical sampling of the north plateau plume area in 1993 and 1998 (the number of samples varied with the metal). The data set with historical-and 2008 north plateau concentrations was statistically compared with background concentrations from the 16 background subsurface soil samples used in this report (from GPBGOI-08 through GPBG05-08 and BH-38) using the single-factor ANOVA described in Appendix E-1. The ANOVA was used to test.

whether the means from the two groups (north plateau plume area data vs. background data) could have been drawn from the same population, or whether they, are so different that it must be assumed they were sampled from I

different populations.

In this evaluation, the null hypothesis being tested was that the mean from the north plateau plume area samples iwas significantly higher than that of the background samples (a "one-tailed" hypothesis, since we were interested only in downgradient values exceeding upgradient values). The acceptable error level was set to P<0.05 (equivalent to a 95% confidence level).. The single-factor ANOVA function of Microsoft Excel was again used to run a test for each metal: Results are summarized in Table E-2a.. Documentation of the complete ANOVA analysis for each metal is provided in Table E-2b. Results from the characterization data set were determined to begreater than those from the background data set (that is, the null hypothesis was accepted) if the following two conditions were met:

3(1)

The "F" value from the ANOVA exceeded the critical value of "F ("F crit' in the ANOVA output tables), and (2) The mean value for the "North Plateau Plume Area" data set exceeded the mean "Background" value'.

m

==

Conclusions:==

In all instances, the null hypothesis was rejected. Results from the north plateau sample data set did not exceed the background sample data set for any of the total metals measured. Therefore, it was concluded that, even though the highest background value may have been exceeded by an individual north plateau plume value, total metals concentrations from north.plateau plume subsurface soils, as a group, were not significantly higher 3

• than the background sample data set, as a group.

WVDP-494 Rev. 0 Page 567 of 1158 Appendix E-3 Determination of Background Metals Concentrations in Groundwater Background groundwater metals data were taken from routine background groundwater monitoring wells 301, 401, 706,.and 1302 in the S&G unit on the north plateau. Groundwater data collected from sampling of these wells under the Groundwater Monitoring Plan (WVDP-239) from 1991 through the. end of 2008 were used in calculations.

Minimum, maximum, and upper 95% limit (i.e., the mean plus two standard. deviations) were calculated for each metal and are presented.in Table E-3a. Results from duplicate and replicate samples were averaged before any calculations were performed. The maximum observed concentration was higher than the upper 95% limit for 19 of the 24 metals measured in groundwater, The upper 95% limit was.higher than the maximum for the remaining 5 metals. The upper 95% limit values were used for initial screening of the Geoprobe groundwater. samples for the West Valley Demonstration Project North Plateau Plume Characterization Report (WVDP-494) to follow the.

screening procedure used in the WVDP-239 where routinely monitored groundwater data are screened against trigger levels to facilitate reporting of trends.

Elevated chromium and nickel concentrations attributed to well corrosion were noted in wells 301, 401, and 706 over the monitoring period. All results suspected to be affected by corrosion (Le., all. chromium and nickel results for 301 and 401, and all results after May 2004 from 706) were excluded from the background calculations.

==

Conclusions:==

. The groundwater background screening values are highlighted in the Table E-3a below and are reiterated on Table 11 of this report. The complete data set used for calculation of the background metals concentrations in groundwater are provided in Table E-3b..

'Background data were from wells WNW0301, WNW0401, WNW0706, and WNW1302 in the sand and gravel unit on the North Plateau.

The upper 95% limit is set equal to the mean plus two standard deviations. Data were rounded to three significant digits or the closest integer. This value was used for comparison with downgradient results.

(See Table 11 in the text, which lists background screening criteria for Appendix 33 metals in groundwater.)

3No data were available for this constituent at 1302.
