PSEG Nuclear LLC P.O. Box 236, Hancock Bridge, NJ 08038-0236 0 PSEG NuclearLLC March 15, 2007 SCH07-032 Kent Tosch Manager Radiation Protection Programs Bureau of Nuclear Engineering New Jersey Department of Environmental Protection 33 Arctic Parkway Trenton, New Jersey 08625 QUARTERLY REMEDIAL ACTION PROGRESS REPORT, FOURTH QUARTER 2006 PSEG NUCLEAR, LLC, SALEM GENERATING STATION

Dear Mr. Tosch:

• PSEG Nuclear LLC (PSEG) has prepared this Quarterly Remedial Action Progress Report (RAPR) for the dual purposes of providing a summary of groundwater remediation activities conducted since the submission of the previous RAPR in November 2006 and to recap the activities conducted in the year 2006 at the PSEG Nuclear, LLC, Salem Generating Station (Station). The Station is located on Artificial Island in Hancock's Bridge, Salem County, New Jersey. The Station location and layout are presented on Figures 1 and 2, respectively. Groundwater remediation activities are being conducted to address tritium detected in shallow groundwater adjacent to and south of the Salem Unit 1 Reactor Containment and Fuel Handling Building.

The release of tritium contaminated water to the environment ceased in February 2003 when the Salem Unit 1 telltale drains were cleared and the Spent Fuel Pool (SFP) water that had accumulated behind the liner was drained. Following the liner draining activities, a regular program was instituted whereby the telltales drains are monitored for flow and the seismic gap is drained on a regular basis. Data related to the seismic gap were previously provided in the 2006 Third Quarter RAPR. The data demonstrated that no short lived gamma radioisotopes have been detected in the gap since May 2004 when monitoring of the water in the seismic gap started, supporting this conclusion that the release has ceased. Other supporting data include decreasing tritium concentrations in groundwater just outside the seismic gap. At present, it is estimated that approximately 2 to 5 Curies remain in the plume where tritium exists above the NJDEP Ground Water Quality Criteria (GWQC). The range is dependant on the amount of tritium drawn back through the seismic gap, the degree of variability in the tritium SzI'

concentrations of the groundwater, and the amount of mass held in dead end pore O space.

Project Background In April 2004, a Remedial Investigation Report (RIR) was submitted to the New Jersey Department of Environmental Protection Bureau of Nuclear Engineering (NJDEP-BNE) presenting the details and results of groundwater investigation activities that were conducted following the discovery of tritium in groundwater adjacent to Salem Unit 1.

The results of the remedial investigation indicated that the source of tritium detected in groundwater was the Spent Fuel Pool, the tritium release to the environment had been stopped, and that tritium had not migrated to the property boundary above the New GWQC for tritium.

The remedial investigation produced a comprehensive body of knowledge that was used as the basis for developing a remedial action strategy designed to hydraulically contain the further migration of tritium in groundwater that had previously been released from the seismic gap, and to reduce the concentration of tritium in the shallow groundwater adjacent to Salem Unit 1. In July 2004, a Remedial Action Work Plan (RAWP) was prepared and submitted to the NJDEP-BNE presenting the proposed remedial actions for achieving these objectives. The RAWP, which proposed the operation of a groundwater extraction system, was approved by the NJDEP in

• November 2004. In April 2004, prior to the submittal of the RAWP, PSEG initiated a groundwater extraction pilot study designed to demonstrate the effectiveness of groundwater extraction for achieving the remedial objectives. The pilot study proved to be effective and a full-scale groundwater extraction system was subsequently installed.

The following sections present the details and results of activities conducted since the submittal of the November 2006 RAPR, document the progress of remedial actions conducted to date, and provide a discussion of upcoming activities projected for the next reporting period.

Continued Groundwater Monitoring The data indicate that significant decreases in groundwater tritium concentrations have been accomplished to date. Groundwater monitoring activities continued through this reporting period in accordance with the schedule provided to NJDEP-BNE. These activities consisted of the periodic collection of groundwater samples from the 36 Station monitoring wells. A summary of the Station monitoring wells details are included in Table 1 and well locations are presented on Figure 2. The planned schedule through April 2007 is included as Appendix A. The sampling program is designed to ensure representative data are collected that meet the objectives of the investigation and provide the information necessary to evaluate plume containment. Analytical results for groundwater samples collected from site monitoring wells are presented in Table 2.

• Groundwater samples are submitted to Salem Chemistry for analysis for tritium and gamma isotopes. Samples indicating tritium concentrations less than 20,000 picocuries per liter (pCi/L) are sent to Maplewood Testing Services for more refined analysis. The large volume of analytical data collected to date indicates that plant related gamma-emitting isotopes have not been detected in any groundwater samples collected during the groundwater investigation.

An update of analytical results for groundwater samples from the Station monitoring wells through December 2006 are summarized in Table 2 and are presented on Figure

3. Historic analytical results were presented in the RIR and previous RAPRs. Included on Figure 3 are: panel 1) the extent of tritium in groundwater at the completion of the remedial investigation (Baseline Plume), which was completed in April 2004; panel 2) the extent of tritium in groundwater in December 2005 following eight months of the pilot groundwater remediation activities and one year of the full scale system remediation activities; and, panel 3) the current extent of tritium in groundwater. Based on a review of the three panels on Figure 3, it is apparent that the mass of tritium in groundwater has been significantly reduced by the remedial efforts completed to date. Details regarding these activities are included in this report. It should be noted that the tritium concentrations in all wells is currently below 100,000 pCi/I for the first time since the inception of the investigation and remedial actions. This is a very positive accomplishment for the remediation program.

• Specific details regarding the analytical results for the groundwater samples are presented in the following sections. The analytical results for the monitoring wells were evaluated based on the water-bearing zone in which the monitoring wells are screened.

The three primary water-bearing units being investigated beneath the Station are: 1) the Vincentown Formation; 2) the shallow, water-bearing unit within the limits of the cofferdam; and, 3) the shallow, water-bearing unit outside of the limits of the cofferdam.

Appendix A presents the planned monitoring schedule through April 2007.

Tritium Analytical Results for the Vincentown Formation Groundwater quality for wells screened in the Vincentown Formation, which consist of Well V, Well K, Well L, Well P, and Well Q, are currently monitored on a semi-annual basis. Groundwater samples collected from these wells are analyzed for tritium and gamma-emitting isotopes. Analytical results of groundwater samples collected from Wells P and Q indicate concentrations of tritium below the laboratory detection limits.

Tritium has only been detected at a concentration above laboratory detection limits once (July 2004) in groundwater from Well L; however, the tritium concentration was well below GWQC. Based on the long term trend for this well, it is believed that the July 2004 data point was not indicative of actual tritium concentrations. Analytical results of groundwater samples collected from Well K have never indicated tritium concentrations S greater than 1,170 pCi/L, approximately four year ago, and are currently in the lower 3

portion of its range (<153 to 1,170). At the request of the NJDEP BNE, an additional

• monitoring well, Well CB, was installed in the vicinity of Well K to provide additional data for this substrate. This is discussed further in Appendix B.

Well V continues to exhibit concentrations of tritium between 181 and 400 pCi/L. The maximum concentration observed in samples collected from Well V was 402 pCi/L in September of 2004. Concentrations in Well V are currently below 200 pCi/L.

Analytical results of groundwater samples collected from the monitoring wells screened in the Vincentown Formation continue to indicate that the release of water from the Spent Fuel Pool has not migrated below the shallow water-bearing unit.

Tritium Analytical Results for Wells Installed Within the Limits of the Cofferdam Wells screened in the shallow, water-bearing unit within the limits of the cofferdam consist of Well M, Well N, Well 0, Well R, Well AC, Well AE, Well Al, Well AM, Well AN, and Well AO. Based upon their location relative to the Salem Unit 1 seismic gap, analytical results of groundwater samples collected from these wells have historically and do presently indicate the highest tritium concentrations in groundwater at the Station.

Trend charts of historic tritium concentration for select wells are presented on Figure 4.

• Analytical trends for wells screened within this unit exhibiting tritium concentrations above NJDEP GWQC continue to show generally decreasing trends. This provides an indication that extraction through the operation of the Unit-1 seismic gap drain, and operation of the groundwater extraction system are successful in decreasing tritium concentrations within this unit.

Well AC is located directly southeast of the Salem Unit 1 seismic gap and has indicated tritium concentrations as high as 15,000,000 pCi/L. Analytical results of more recent groundwater samples collected from this well indicate tritium concentrations of approximately 32,900 pCi/L. The decrease in tritium concentrations at Well AC is additional confirmation that the release of water from the SFP has been stopped and the operation of the seismic gap drain and the groundwater recovery system (discussed later in the report) are effectively reducing concentrations of tritium in groundwater and providing hydraulic control of the plume.

An increased concentration of tritium was detected in Well AM in March, believed to be caused by the movement of a localized portion of the tritium plume. The mobile unit was placed in service to address and spot remediate the increase. After the concentration of tritium peaked in September, analysis of subsequent samples indicated concentrations were generally decreasing. A slight increase in tritium concentrations at Well 0 has also been detected recently. This is consistent with detections from both last winter and the previous winter, and consistent with reduced infiltration.

4

Figure 4 clearly illustrates that the concentration spike observed in Well AC was

• insignificant in relation to the long term concentration trends. Additionally, Figure 4 shows that although other fairly significant spikes have been exhibited by wells within the plume, the overall trend is towards significantly lower concentrations.

Tritium Analytical Results for Wells Installed Beyond the Limits of the Cofferdam The wells installed in the shallow, water-bearing unit beyond the limits of the cofferdam are Well S, Well T, Well U, Well W, Well Y, Well Z, Well AA, Well AB, Well AD, Well AF, Well AG (Shallow and Deep), Well AH (Shallow and Deep), Well AJ, Well AL, Well AP, Well AQ, Well AR, Well AS, and Well AT. At the request of the NJDEP BNE, an additional monitoring well, Well CA, was installed in the-vicinity of Well U.. This is discussed further in Appendix B. These wells are screened either just above the clay confining unit that separates the shallow water-bearing unit from the Vincentown Formation, or in the interval indicating the highest tritium concentrations found in the shallow water-bearing unit at each boring location outside the cofferdam at the time of the Supplemental Investigation completed in August 2003.

As discussed in previous RAPRs, an increased concentration of tritium was detected in Well AP in March 2005. PSEG responded by activating the mobile groundwater extraction unit to spot remediate the area. The result has been a continuing downward trend in concentrations. In November and December 2005, concentrations of tritium were detected in Well W above the GWQC, these detections are thought to be part of the same effect previously observed at Well AP. The concentrations in Well W remained elevated until July 2006. Concentrations are currently below the GWQC, although fluctuations have been observed.

The tritium concentration trends for wells screened in the shallow, water-bearing unit indicate that the groundwater extraction system has demonstrated the ability to achieve the remedial action objectives (i.e., reduce the mass of tritium in groundwater, and maintain hydraulic control). The current distribution of tritium in groundwater (December 2006) is presented on Figure 3, along with the distribution of tritium prior to the initiation of the pilot study (March 2004) and in December 2005. As shown on Figure 3, the mass of tritium in groundwater has continued to decrease through the operation of the groundwater extraction pilot study system and operation of the full-scale system.

Groundwater Extraction In accordance with the RAWP, groundwater extraction activities completed to date consisted of the operation of the pilot-study from April 26, 2004 to February 11, 2005 and operation of the full scale groundwater recovery system (GRS) from February 16, 2005 to the present.

5

Full-Scale System Based on the results of the pilot study, a full-scale system GRS was designed and installed. The objectives of the full-scale system are the following: 1) to maintain hydraulic containment of the tritium plume; and, 2) to reduce tritium concentrations in groundwater.

The present full-scale system consists of the extraction of groundwater from Wells AB, AD, AJ, AN, AO, AS, and AT. Well S is not currently operating and has not been in operation during 2006 as a result of its low yield and resulting pump failures. Well AO was also not operating during the first quarter of 2006 due to low yield but has been in operation during the last three quarters of 2006. Groundwater extracted from the wells is processed in accordance with the Station's United States Nuclear Regulatory Commission (USNRC) license and plant procedures.

Mobile Groundwater Recovery Unit In response to increased concentrations of tritium detected in Well AM beginning in March 2006, the mobile groundwater recovery unit was activated to recover groundwater from this location. The effectiveness of the use of the mobile groundwater recovery unit was evaluated through increased monitoring of groundwater at this well.

The fourth and last tank collected from Well AM was discharged on October 30, 2006 after concentrations had dropped significantly. As noted above, recent concentrations have been fluctuating within the range where they have previously existed.

Following extraction, groundwater held in the mobile unit is re-circulated for approximately two hours and sampled for characterization. The groundwater is then disposed in accordance with the Station's United States Nuclear Regulatory Commission (USNRC) license and plant procedures. The analytical results for samples of the water collected by the mobile unit are included in Table 3.

The mobile unit was effective in removing the groundwater with elevated concentrations of tritium from the area around Well AM. As of July 21, 2006, the concentration had decreased from 866,000 pCi/L (May 16) to 37,500 pCi/L and, as of October 9, 2006 the concentration had further decreased to 19,530 pCi/L. Most recently, tritium concentration (December 9) was 37,100 pCi/L. Because of the non-uniform distribution of tritium in the subsurface and the relatively low yield of Well AM, tritium concentrations in groundwater recovered by the mobile recovery unit tend to exhibit higher concentrations than the values exhibited from the routine low flow samples collected from this well. The discrepancy is a result of the greater zone of capture realized when the well is aggressively pumped.

Total System Effluent Data and Evaluation 6

The full-scale GRS became operational on February 16, 2005. The system operated in

• various configurations as part of the shakedown process for approximately the first month. The full-scale system discharges continuously in accordance with the Station's USNRC permit allowing the full-scale system to be more effective and efficient than the pilot-scale system. As of December 31, 2006, the full-scale system has recovered greater than 12.5 million gallons of groundwater. This is equivalent to an average recovery rate of just over 15 gallons per minute or greater than 20 times the recharge rate for the extraction area (calculated to be 0.7 gallons per minute, based upon an assumed percentage of annual precipitation). Table 4 presents a summary of the full-scale system discharges through December 31, 2006.

Water-Level Data and Evaluation Water-level measurements from the extraction and select observation wells have been monitored to demonstrate that the full-scale groundwater extraction system has hydraulically contained the migration of tritium in groundwater. To demonstrate this effectiveness, water levels are periodically collected and evaluated. Table 5 provides the groundwater level measurement data.

Figures 5, 6, and 7 present the groundwater surface contours during operation of the full-scale groundwater extraction system on March 29, 2006, May 16, 2006, and September 28, 2006, respectively. Table 5 presents the water level measurement data.

While a fourth quarter set of water levels were not obtained and evaluated as a result of

• other well installation work being conducted at the site, it is apparent from Figures 5, 6 and 7 that the groundwater extraction system has effectively developed a capture zone that is controlling the plume by hydraulically containing groundwater in the area where elevated tritium exists. Groundwater levels will be recorded and evaluated during the first quarter of 2007.

Cumulative Curies Removed The various groundwater recovery activities conducted to date have been successful in recovering tritium from groundwater at and downgradient of the Salem Unit 1 seismic gap.

Full-Scale System As detailed in Table 4, approximately 1.37 curies of tritium have been recovered from the operation of the full-scale GRS through December 29, 2006. . Approximately 0.93 curies of tritium were removed by the pilot system. Figure 8 summarizes the results of the groundwater remediation activities conducted using the well field which includes both the pilot study and the permanent system. As of December 29, 2006, greater than 2.3 curies had been removed by the well field. The effectiveness is emphasized by the decrease and stabilization in system effluent concentrations since the activation of the full scale system in February 2005. System effluent concentrations are presently

• b around 13,800 pCi/L. This indicates that the GRS has been successful in significantly 7

decreasing the concentrations of tritium in the subsurface as discharge concentrations

• are now 13 percent of the peak concentration (109,000) discharged by the GRS in March 2005. The mass of tritium in the plume was recalculated in early 2006 to be in the 2 to 5 Curie range (depending on the amount of tritium drawn back through the seismic gap, the actual variability in discharge concentrations and the amount of tritium remaining in dead end pore spaces) at concentrations above the NJDEP GWQC. This suggests the GRS tritium removal may result in achieving end criteria ahead of the previously communicated schedule. The ongoing data collection will provide additional data to confirm this preliminary conclusion later in 2007.

Other Remedial Actions In addition to the operation of the GRS, seismic gap drains in Salem Unit 1 and Unit 2 are being used to drain the water from these gaps recovering concentrations of residual tritium from the seismic gap. The following sections provide a brief overview of the seismic gap draining activities.

Operation of the Seismic Gap Drain The permanent drains installed in the Salem Unit I and 2 seismic gaps facilitate the periodic collection and characterization of groundwater accumulating in the seismic gaps. The operation of these gap drains creates an inward gradient towards the gaps facilitating the recovery of water from low accessibility areas. Table 6 summarizes the

• results of the seismic gap draining activities. A comparison of Table 2 and Table 6 reveals the concentrations of tritium in the water recovered in the Unit 1 drain have been significantly higher than those detected in groundwater samples collected from Well AC and Well AM located to the southeast and southwest of the seismic gap, respectively. The Unit 1 seismic gap drain is effectively removing residual Spent Fuel Pool water in the seismic gap, and is resulting in the reduction of tritium concentrations in groundwater adjacent to the seismic gap. As shown on Figure 9, greater than 10 curies of tritium has been recovered from the operation of the Unit 1 seismic gap drain.

The estimated mass of tritium removed from the seismic gap is not currently being calculated because the actual volume of water being removed cannot be accurately measured and the fact that the tritium concentration is not continuously measured. As of the end of September 2005, approximately 4 curies had been removed from the seismic gap. The concentration distribution of tritium at the gap drains will vary with the source of the water being drained, the amount of precipitation since the last draining, and the movement of the water within the lower reaches of the seismic gap.

As of early March 2007, PSEG initiated a continuous draining of the seismic gap drains on both Salem units to evaluate the impact on measured tritium concentrations and any effect on local area tritium concentrations. Most importantly, continuous draining provides a positive assurance of an inward gradient of groundwater to the seismic gap and assures that there is no further potential to discharge to the environment.

Concentrations of tritium from the seismic gap are shown on Figure 9, The 8

concentration of tritium from the seismic gap is anticipated to decline with the

• continuous draining of the seismic gap..

Analytical results for water samples are collected from the Unit 2 seismic gap drain to provide data on radionuclide concentrations of constituents to assure that there is not an indication of constituents that would indicate a similar release occurred from the Unit 2 Spent Fuel Pool. Additionally, no plant related gamma emitting isotopes have been found in samples collected from the Unit 2 seismic gap drain.

As evidenced by the lack of short-lived gamma-emitting isotopes, samples collected from the Unit 1 gap drain do not indicate an ongoing or recent release of spent fuel pool water. Additionally the Unit 2 seismic gap drain water contains no plant gamma activity.

Water samples will be obtained from both gap drains on a periodic basis to evaluate the water that has accumulated in the respective seismic gaps and to provide a backup warning of a potential release of spent fuel pool water. The primary method for determining the potential release of spent fuel pool water is the monitoring of the SFP tell-tale drains and seismic gap drains.

Installation of Additional Wells Additional monitoring wells were installed on December 4 and 5, 2006 as requested by the NJDEP in order to further investigate tritium concentrations in the vicinity of Well K.

Two wells were installed, one shallow well screened in the shallow water bearing unit

• outside the limits of the cofferdam above the Kirkwood Formation (Well CA) and one deep well completed in the Vincentown Formation (Well CB).

The monitoring wells were installed using vacuum excavation techniques due to the extensive subsurface utilities and infrastructure located within the area of investigation as well as the mud rotary drilling technique. The location and well construction details for the new groundwater monitoring wells are shown on Figure 2 and in Table 7, respectively. NJDEP Bureau of Water Allocation Monitoring Well Records, well construction logs, boring logs, and a detailed description of installation activities are included in Appendix B. The monitoring wells were developed using a combination of surging and pumping techniques. In accordance with N.J.A.C. 7:26E-4.4(g) [7], the monitoring wells were surveyed by a New Jersey-licensed surveyor. The Monitoring Well Certification Form B for each well is provided in Appendix C. The wells were not sampled during the reporting period, but will be gauged and sampled during the next scheduled sampling event (Appendix A).

Upcoming Activities Activities projected for the First Quarter of 2007 (January through March) include the following:

Refine the procedures and protocols as necessary to adaptively manage the operation and sampling of the full scale groundwater extraction system; 9

0 Continue to measure groundwater levels and evaluate flow and plume containment;

• Collect groundwater samples from new wells; 0 Continued monitoring wells groundwater sampling and analysis activities; and,

• Continued operation and evaluation of data obtained through the full-scale groundwater extraction system.

• Initiate [completed] and monitor continuous draining of seismic gap drains If you have any questions or comments regarding the contents of this report, please do not hesitate to contact me at (856) 339-5066.

ARCADIS Appendix A Schedule

ARCADIS Appendix B A detailed description of installation activities, Boring logs/Well construction logs, and Monitoring well records

ARCADIS Summary of New Monitoring Well Installation - December 2006 Four additional monitoring wells for the tritium project were installed in December 2006.

Objectives Two additional groundwater monitoring wells (Well CA and Well CB) were installed at pre-determined locations surrounding Salem Unit 1 to evaluate the extent of tritium in groundwater in the vicinity of Well K and two monitoring wells (Well BX and Well BW) were installed near the Auxiliary Boiler Building to investigate a potential leak, and one monitoring well. The locations of the monitoring wells are shown on Figure B-1. The specific purposes for each of the monitoring wells are as follows:

" Monitoring Wells CA and CB were installed northeast of the cofferdam to characterize groundwater quality in the area upgradient of the Salem Generating Station Unit 1 Spent Fuel Pool and downgradient of Well K in both the shallow water bearing unit outside the cofferdam and the Vincentown formation; and,

" Monitoring Wells BX and BW were installed northeast of the cofferdam and southwest of the Auxiliary Boiler Building to investigate a potential leak from the House Heating Boiler.

Field Implementation Between December 1 and December 5, 2006, Monitoring Wells CA, CB, BX, and BW were installed. The monitoring wells were installed by B.L. Myers Bros., Inc using a combination of direct-push, vacuum extraction, and mud rotary drilling equipment. ARCADIS personnel supervised monitoring well installation activities. A summary of the well construction details for the Station monitoring wells is presented in Table 1. Appendix C presents the boring logs, well completion details, NJDEP Bureau of Water Allocation Monitoring Well Records, and Monitoring Well Certification Forms (Form B) for the wells.

Monitoring Wells CA, which is screened in the shallow water bearing unit outside the limits of the cofferdam, was constructed with four-inch diameter Schedule 40 PVC casing and well screen (0.010 slot). Well CB, which is screened in the Vincentown Formation, is constructed with a two-inch diameter Schedule 40 PVC casing and screened with a Schedule 40 PVC V-wire Wrap. The Auxiliary monitoring wells, Well BX and BW were constructed of one-inch diameter Schedule 40 PVC casing and well screen (0.010 slot). Well BV was constructed of four inch diameter Schedule 40 PVC casing and well screen (0.010 slot). A gravel pack consisting of Morie No. 1 sand was installed to a minimum of one foot above the top of the well screen. The remainder of the borehole was grouted with neat cement containing approximately five percent bentonite. The grout was installed in the annular space around the casing using a grout pump and a tremie-pipe.

ARCADIS Monitoring Well CA was installed outside of the cofferdam. The well was constructed with screened intervals in the hydraulic fill and riverbed deposits encountered above the Kirkwood Formation. The screened interval for this well spans from 28 to 38 feet bgs. Monitoring Well CB, installed northwest of the cofferdam, is constructed with a screened interval from 70 to 80 feet bgs in the deeper Vincentown Formation. Monitoring Well BX and BW were constructed with screened intervals from 5 to 10 feet bgs.

The monitoring wells were developed using a combination of surging and pumping techniques.

Development of the monitoring wells was considered complete when the discharge appeared to be sediment free. Following installation, Stires Associates, P.A., a licensed New Jersey surveyor, surveyed the monitoring wells. Top of casing elevations, reported in elevations relative to plant datum, are included in Table 1. Monitoring Well CertificationForm Bs for the wells are included in Appendix C. In August 2003, PSEG Nuclear, LLC conducted a separate survey to determine the relationship between plant datum and mean sea level (NAVD 1988). The results of the survey indicate that the conversion factor from plant datum to NAVD 1988 is -89.92 (i.e., to convert from plant datum to NAVD 1988 subtract 89.92 feet).

Investigation-derived waste (IDW) (i.e., drill cuttings, purge water, and decontamination materials) generated during the installation of the monitoring wells was containerized in 55-gallon steel drums and labeled for identification. Characterization and disposal of the IDW was in accordance with Station radiological controls and waste management programs. During monitoring well installation activities, Station personnel from radiation protection monitored radioactivity in the work area to ensure the safety of project personnel and as a preliminary screening measure for IDW.

Screening samples collected during the investigation are attached as Table B-2. No detections of tritium above the NJ GWQC were observed in the screeing samples.
