Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey Executive Summary ARCADIS, Inc. (ARCADIS), on behalf of PSEG Services Corporation (PSEG), has prepared this Initial Groundwater Investigation Report and Remedial Investigation Workplan (RIWP) Addendum to document the findings of an ongoing groundwater investigation at the PSEG Nuclear, LLC Salem Generating Station (the Station) located on Artificial Island in Lower Alloways Creek Township, Salem County, New Jersey to propose additional activities meant to further this investigation. The groundwater investigation is being conducted in accordance with a Remedial Investigation Work Plan (RIWP) that was submitted tothe New Jersey Department of Environmental Protection (NJDPE) in June 2003. The remedial investigation was initiated in September 2002 following the detection of low-level radioactive contaminants on the shoes of several Station technicians. Initially, the investigations indicated that the likely source of the low-level radioactive contaminants was L water seeping through small cracks in the 78-foot Mechanical Penetration Room of the Unit I Auxiliary Building. This water had likely leaked from the Spent Fuel Pool for Unit 1, and accumulated in the seismic gap between the Unit 1 Reactor Containment Building and the Unit 1 Fuel Handling Building. Background information, other site-related information, and a summary of the initial groundwater investigation activities conducted following the detection of low-level radioactivity were provided in the June 2003 RIWP. The initial groundwater investigations summarized in the June 2003 RIWP included: 1) details on the collection and analysis of water samples from locations within the Station that were suspected to be sources of the low-level radioactivity (e.g., the water and the crystallized boric acid observed on the wall of the 78-foot Mechanical Penetration Room of the Unit 1 Auxiliary Building); 2) an evaluation of water that had accumulated in the Unit I Spent Fuel Pool telltale drains; and,
- 3) a summary of the groundwater investigations conducted through August 2003 to determine if water that had accumulated in the telltale drains, and ultimately the Styrofoam-filled seismic gap, had migrated beyond the limits of the physical structure.
Well Installation and Groundwater Sampling The initial investigation included the installation and sampling of eight monitoring wells or direct-push points (Well K through Well R; M and R being direct-push points). Analytical results of groundwater samples collected from the monitoring wells indicated that tritium was detected at concentrations above 3,000 picocuries per liter (pCi/L), the interim further investigation criterion proposed in the June 2003 RIWP, in groundwater samples collected from Monitoring Wells M, N, 0 and R. Tritium was also detected in the groundwater sample collected from Well N on January 30, 2003 at a concentration above the New Jersey ES-I
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey Groundwater Quality Criterion (GWQC) for tritium in groundwater of Class RA aquifers (20,000 pCi1L). Five additional Monitoring Wells S through W were installed between May 5 and June 18, 2003 and existing Monitoring Wells M and R were replaced with properly constructed and developed monitoring wells. Figure ES-1 shows the monitoring well network utilized in the RI. During 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 investigation-derived waste (IDW). Prior to and during monitoring well installation activities in May and June 2003, Maplewood Testing Services (Maplewood) collected groundwater samples from the existing monitoring wells. Groundwater samples are being collected in accordance with the low-flow sampling procedure outlined in the Quality Assurance Project Plan (QAPP), which was included as an appendix to the June 2003 RIWP. Following installation and development of the new monitoring wells, the monitoring well sampling program was modified. The details of the modified sampling program are as follows: Wells L, P, and Q: Due to the relatively low levels of tritium (less than 1,000 pCifL) historically detected in groundwater samples, these wells have been sampled on a monthly basis. Wells K, M, N, 0, R, S, T, U, V, and W: These wells are sampled every two weeks. The groundwater samples were analyzed by Maplewood for tritium, sodium, boron, and gamma-emitting isotopes. All samples were non-detect for gamma-emitting isotopes. In July 2003, all tritium concentrations, with the exception of Monitoring Wells M and S, were below the GWQC of 20,000 pCi/L. The replacement well for Monitoring Well M, within the cofferdam, has tritium levels at approximately 62,000 pCi/L and Well S, located in the riverbed sands and gravels outside the cofferdam, had an initial level of 3,500,000 pCi/L. Elevated boron concentrations in Well S (57 parts per million or ppm) indicate a different tritium source from Well M (approximately 0.200 ppm, which is background). Additional groundwater samples were collected for a one-time analysis for technetium-99, iodine-129, and for use in age dating (tritium to helium-3 ratio). The research analytical. laboratories at the University of Rochester and Purdue University perform these analyses. Analytical results of the groundwater age for Monitoring Wells K, L, P, Q, U and T indicate these waters to be non-impacted by facility operations. Groundwater age determination results for the remaining wells as well as iodine-1 29 and technetium-99 analytical results for all of the wells are pending. These results will be presented in the comprehensive RIR. ES-2
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey Aquifer Testing The pumping tests proposed in the RIWP were not conducted due to water disposal issues associated with the elevated tritium levels in wells M and S. Slug tests were performed in Wells N, 0, and U in August 2003. The slug tests were designed such that no groundwater was extracted. Monitoring Wells N and 0 are screened in the structural fill. The estimated hydraulic conductivity at Well N is between 0.09 and 0.14 ftlday. The estimated hydraulic conductivity at Well 0 is between 3.6 and 4.3 ft/day. The estimated hydraulic conductivity value for Monitoring Well U screened in the riverbed deposits was 2.95 feet per day. Tidal Investigation Pressure transducers were installed in Wells L, M, and W between July 29 and August 5, 2003 to evaluate the tidal influences of the Delaware River on site water levels. Well W installed in the riverbed sands and gravels, and Well M screened in the structural fill within the cofferdam showed no water-level response to tidal variations. Well L installed in the Vincentown Formation (the first confined aquifer beneath the site) has a 3 feet change in water level in response to a 6 feet change in tide. This response is likely caused by changes in the hydraulic head exerting force on the clay, confining-unit (the aquitard overlying the Vincentown), which based upon site lithology, extends westward beneath the Delaware River. These data indicate that tidal variations in the Delaware River have no effect on the movement of tritiated groundwater identified in the surficial aquifer (sediments above the clay, confining-unit). Supplemental Investigation A "supplemental" groundwater investigation was initiated in July 2003 in response to the detections of tritium in groundwater samples collected from Monitoring Well S. The objectives of the supplemental investigation were as follows: 1) determine if the tritium measured in groundwater samples collected from Monitoring Well S was discharging to the river, 2) delineate the vertical and horizontal extent of the tritium in groundwater in the vicinity of Monitoring Well S; and 3) evaluate the potential sources of tritium in Monitoring Well S. The groundwater investigation consisted of collecting grab groundwater samples from direct-push boreholes and temporary well points screened at various depths and locations along the Delaware River, as well as surrounding Well S. Groundwater samples were submitted for analysis for tritium, boron, and gamma-emitting isotopes. Figure ES-2 shows the 37 proposed boring locations; samples were to be collected at as many as three depths at each location. Borings 1 through 8 were proposed to evaluate concentrations along the Delaware River to assess the potential for off-site ES-3
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station HancocWs Bridge, New Jersey migration. Borings 9 through 18 and Borings 31 through 37 were proposed near Station infrastructure to identify possible sources of tritium. These potential sources include the "rad waste" line, the Unit I Spent Fuel Pool, the Unit I refueling water storage tank, and the Unit I primary water storage tank. Borings 19 through 30 were proposed in the vicinity and downgradient of Well S to determine the extent of tritium. Preliminary Findings The primary objective of the groundwater investigation is to determine whether water from the Unit I Spent Fuel Pool that accumulated in the Styrofoam-filled seismic gap migrated beyond the seismic gap and into soils contacting the gap. Monitoring Wells R and N were installed at the north and south ends of the seismic gap, respectively, to assess this pathway. The chemistry and water-level data indicate that there has not been a release of water from the north side of the seismic gap. This conclusion is based upon two sets of data. First, tritium concentrations in Well R, located near the north end of the seismic gap, are less than 5,000 pCi/L. Second, water-level elevations in Well R are at least two feet higher than in Well N; if both ends of the seismic gap are in contact with foundation soils, groundwater may be flowing into the north end of the gap and out of the south end of the gap. Further assessment of potential leakage from the south end of the seismic gap will be made following installation of an additional monitoring well near the south end of the seismic gap. Analytical results of groundwater samples collected from this well, in addition to the results of iodine-129 and technetium-99 sampling, will be used in an effort to complete a final assessment. The preliminary findings from the supplemental investigation are summarized as follows: (1) the limit of groundwater concentrations above the GWQC for tritium (20,000 pCiIL) has been defined as shown on Figure ES-2; (2) an expanded area in the vicinity of Well S with tritium levels above 500,000 pCi/L has been quantified as shown on Figure ES-2; (3) a completed pathway between a potential source and groundwater has not been identified; and (4) extensive on-site monitoring of shallow groundwater indicates no tritium above permissible levels has migrated to the Station boundary or the Delaware River. The available tritium and boron data indicate two potential sources of tritiated water. At Well S, elevated levels of boron (57 ppm) suggest primary water. The nearest potential sources are the "rad waste line" and the seismic gap between the Fuel Handling Building and Unit I Containment where water the Spent Fuel Pool has accumulated. A pathway from the "rad waste line" could not be completed as concentrations in groundwater along this line are 100 times lower than in Well S. Similarly, groundwater concentrations in Well N between the seismic gap and Well S are 100 times lower than in Well S. At Well M, the absence of boron suggests a secondary source or a demineralized source. A potential source is the primary water storage tank. This tank contains demineralized primary water and is located approximately 50 feet away. ES-4
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey Proposed Groundwater Investigation Activities New wells Fifteen additional monitoring wells (Wells Y, Z, and AA through AM) will be installed at various locations around the Salem Generating Station. Their proposed locations are shown on Figure ES-3. The collection and analysis of groundwater samples from the additional monitoring wells will provide supplemental data regarding the extent of tritium in groundwater and the rate of groundwater movement in the onsite riverbed deposits. L Several of the monitoring wells at the Station, both existing and proposed, can also be used for the recovery of tritiated water. Modified Sampling Following the installation and development of the proposed monitoring wells, the existing sampling program will be modified to include the new monitoring wells. Groundwater samples will be collected and analyzed using procedures and methods outlined in the* QAPP. The groundwater samples will be analyzed for tritium, major cations and anions, and gamma-emitting isotopes at specific frequencies depending on the particular well. The groundwater samples will also be analyzed for technetium-99, which will serve as a surrogate for iodine-129 pending the receipt of the iodine-129 analytical results from the analytical research laboratory (Purdue University). Additional Aquifer Characterization Following installation, short-duration pumping tests will be conducted on various monitoring wells screened in both the structural fill within the cofferdam and the riverbed deposits to evaluate aquifer parameters in these units. The pumping tests will include the performance of a six-hour constant-rate pumping test (4 hours of pumping followed by 2 hours of recovery). Water levels will be monitored in the pumping wells and nearby monitoring wells throughout the duration of the tests. The aquifer test data will be analyzed using AQTESOLV for Windows (HydroSOLVE, 2000), and the data collected during the test will be used to calculate the aquifer characteristics such as transmissivity and hydraulic conductivity. The results of the proposed groundwater investigation, including the installation, development, and sampling of the fifteen additional monitoring wells, and the collection and analysis of the aquifer pumping test will be presented in the Remedial Investigation Report (RIR). ES-5
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey Schedule The anticipated schedule for the implementation of the activities outlined above through the preparation of the Remedial Investigation Report is approximately three months longer than the previous schedule presented in the June 2003 RIWP. The schedule is extended for three reasons: (1) completion of a supplemental groundwater investigation in the area of Well S, (2) preparation of an initial groundwater investigation report and RIWP addendum, and (3) the delay in laboratory analyses being conducted by Purdue University. The schedule will be modified as necessary based on comments from the NJDEP-BNE and the results of the investigation activities. ES-6

Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey I Introduction ARCADIS, Inc. (ARCADIS), on behalf of PSEG Services Corporation (PSEG), has prepared this Initial Groundwater Investigation Report and Remedial Investigation Workplan (RIWP) Addendum to document the findings of an ongoing groundwater investigation at the PSEG Nuclear, LLC Salem Generating Station (the Station) located on Artificial Island in Lower Alloways Creek Township, Salem County, New Jersey and to propose additional activities meant to further this investigation. The Station location and layout are shown on Figures 1 and 2, respectively. The details and results of groundwater investigation activities conducted subsequent to the submittal of the RIWP in June 2003, as well as, proposed additional groundwater investigation activities are provided in this report. The scope of work outlined in the June 2003 RIWP was designed to investigate tritium detected in groundwater. 1.1 ProJect Background Investigation activities began in September 2002 following the detection of low-level radioactive contaminants on the shoes of several technicians inside the Auxiliary Building. Initial investigations determined that the likely source of the low-level radioactive contaminants was water that had migrated from the Salem Generating Station Unit I Spent Fuel Pool and accumulated in the Styrofoam-filled seismic gap located between the Unit I Reactor Containment Building and the Unit I Fuel Handling Building. This water then seeped through construction joints and small cracks in the concrete walls of adjoining buildings such as those identified in the 78-foot Mechanical Penetration Room of the Unit I Auxiliary Building. Background information, other site-related information, and a summary of groundwater investigation activities conducted following the detection of low-level radioactivity were provided in the RIWP submitted in June 2003. Investigations summarized in that report included: 1) details regarding the collection and analysis of water samples from locations within the facility that appeared to be likely sources of the low-level radioactivity (e.g., the water and the crystallized boric acid observed on the wall of the 78-foot Mechanical Penetration Room of the Unit I Auxiliary Building); 2) an evaluation of water that had accumulated in the Unit I Spent Fuel Pool telltale drains; and, 3) a summary of the three phases of investigations conducted through August 2003 to determine if water that had accumulated in the telltale drains, and ultimately the Styrofoam-filled seismic gap, had migrated beyond the limits of the Fuel Handling Building. The three phases of investigation included the installation and sampling of eight monitoring wells (Well K through Well R). Analytical results of groundwater samples collected from the monitoring wells indicated that tritium was detected above 3,000 picocuries per liter (pCi/L), the interim further investigation criterion proposed in the June 2003 RIWP, in water samples collected from Monitoring Wells M, N, 0 and R. Tritium was also detected I
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey in the groundwater sample collected from Well N on January 30, 2003 at a concentration above the New Jersey Groundwater Quality Criterion for tritium in groundwater of Class II-A aquifers (20,000 pCi/L). 1.2 Investigation Objectives Analytical results of samples collected following the detection of low-level radioactivity within the Station suggest that water from the Salem Generating Station Unit Spent Fuel Pool may have migrated beyond the Styrofoam-filled seismic gap. The scope of work outlined in the June 2003 RIWP was designed to determine if tritium detected in groundwater samples collected from monitoring wells installed adjacent to and surrounding Unit I of the Salem Generating Station is a result of a release to the environment from the Unit I Spent Fuel Pool, a non-authorized release from other onsite operating or maintenance activities, or the results of authorized releases from other operating practices which may result in elevated background levels of tritium. Additionally, the scope of work was designed to assess the potential for human health risk associated with the tritium detected in groundwater and the need for any further action. 1.3 Report Organization This report provides relevant background information, the details and results of groundwater investigation activities conducted following the submittal of the RIWP in June 2003, and proposed additional groundwater investigation activities in the following sections: Section 2 - Initial Remedial Investigation Activities Section 3 - Initial Hydrogeologic Evaluation Section 4-Supplemental Groundwater Investigation Activities Section 5 - Proposed Groundwater Investigation Activities Section 6 - Revised Remedial Investigation Schedule. 2
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey 2 Initial Groundwater Investigation Activities The following sections provide details regarding groundwater investigation activities conducted at the Station since the submittal of the RIWP. Since the groundwater investigation is ongoing, a comprehensive Remedial Investigation Report will be submitted following the completion of the remaining investigation activities. 2.1 Monitoring Well Installation Between May 5 and June 18, 2003, Monitoring Wells S through W were installed. In addition, existing Monitoring Wells M and R, which were originally installed as temporary wells constructed of mill-slotted Geoprobe sample rods, were replaced with properly constructed and developed monitoring wells. Appendix A presents NJDEP Bureau of Water Allocation Monitoring Well Records for the wells. The monitoring wells were installed by CT&E Environmental Services, Inc. of West Creek, New Jersey using a combination of direct-push, hollow-stem auger, and mud rotary drilling equipment. ARCADIS personnel supervised monitoring well installation activities. Monitoring Wells S through W were constructed with two-inch diameter Schedule 40 PVC casing and well screen (0.010 slot). Well V is also constructed with a six-inch diameter Schedule 40 PVC outer casing. The replacement monitoring wells for Well M and Well R were constructed of one-inch diameter Schedule 40 PVC casing and well screen (0.0 10 slot). A gravel pack consisting of Morie No. I 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. A summary of the well construction details for the Station monitoring wells is presented in Table 1, and well construction logs and boring logs are included in Appendix A. Monitoring Wells S, T, U, and W were installed at various locations outside of the cofferdam that surrounds the Salem Generating Station. The wells were constructed with screened intervals in the hydraulic fill and riverbed deposits encountered above the clay, confining-unit. A more detailed description of the Station geology and hydrogeology is presented in Section 3.0. The screened intervals for these wells range from 22 to 37 feet below ground surface (bgs). Monitoring Well V, installed north of the cofferdam, is constructed with a screened interval from 70 to 80 feet bgs in the deeper Vincentown Formation. 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, the monitoring wells were surveyed by Stires Associates, P.A., a licensed New Jersey surveyor. Ground surface and top of casing elevations, reported in elevations relative to plant datum, are included in 3
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey Table 1. Monitoring Well Certification Form Bs for the wells are included in Appendix A. In August 2003, PSEG conducted a 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 toNAVD 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. Radioactivity was not encountered. 2.2 Monitoring Well Sampling and Analysis Prior to and during monitoring well installation activities, Maplewood Testing Services (Maplewood) collected groundwater samples from the existing monitoring wells. Following installation and development of the new monitoring wells, the monitoring well sampling program for the existing wells was modified. The details of the modified sampling program are as follows: Due to the relatively low levels of tritium (less than 1,000 pCi/L) historically detected in groundwater samples collected from Monitoring Wells L, P. and Q, and the "natural" (or ambient) levels of tritium detected using low-level tritium in-growth techniques (detection limit less than 0.5 pCi/L), Wells L, P, and Q have been sampled on a monthly basis. The remaining monitoring wells (Wells K, M, N, 0, and R) and the newly installed monitoring wells (Wells S through W) have been sampled on a biweekly basis (every two weeks), with approximately half ofthe wells being sampled every week. The initial sampling event that included the newly installed monitoring wells was conducted a minimum of two weeks following the development of the wells. To minimize the influence of turbidity, groundwater samples are being collected in accordance with the low-flow sampling procedure outlined in the Quality Assurance Project Plan (QAPP), which was included as an appendix to the June 2003 RIWP. The use of low-flow purging and sampling procedures results in the collection of groundwater samples from monitoring wells that are representative of groundwater conditions in the geologic formation. This is accomplished by minimizing stress on the geologic formation and minimizing disturbance of sediment that has collected in the well (Groundwater Sampling Procedure, Low Stress (Low Flow) Purging and Sampling, United States Environmental Protection Agency Region II, March 1998). 4
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey As outlined in the low-flow sampling standard operating procedure (SOP) provided in the QAPP, low-flow purging and sampling involves lowering a QED' Micropurge 3/4-inch diameter bladder pump (model SP-%-P) to the midpoint of the screened interval of the monitoring wells. The wells are then purged at a constant rate maintained at or below 200 milliliters per minute. The water level in the well being sampled is monitored during purging, and the pumping rate is adjusted to minimize drawdown. A properly calibrated Micropurge Basics Flow Cell Model MP20DT is used to collect field parameter measurements every five minutes from the recovered groundwater. The parameters include dissolved oxygen (DO), oxidation-reduction potential (ORP), specific conductivity, pH, and temperature. Once the field parameters stabilize (no more than 10 percent fluctuation over three measurements), a sample is collected. The sample is collected directly from the pump discharge line, which is disconnected from the influent line of the flow-through cell to facilitate sample collection. A summary of stabilized field parameters (final readings) for groundwater samples collected from the monitoring wells is provided in Table 2. The field parameter measurements collected during sample collection activities indicated the following: Temperature ranged from 12.50 to 28.89 degrees Centigrade (IC). Specific conductivity ranged from 15.10 to 0.19 microsiemens per centimeter (mS/cm). pH ranged from 5.61 to 8.39 standard units (su). ORP ranged from -201 to +465 millivolts (mV). DO concentrations ranged from 0.09 to 8.02 milligrams per liter (mg/L). The relatively wide range of temperatures is likely due to the influence of the facility infrastructure. The wells indicating higher temperatures are screened in the shallow, water-table aquifer in areas adjacent to subsurface structures that cause an increase in subsurface temperature (e.g., steam blow down lines). A more detailed description of the facility construction is provided in Section 3.3. Before sampling and between each well, all non-dedicated field equipment (e.g., submersible pumps and water-level indicators) is decontaminated following the procedures outlined in the QAPP. Purge water generated during sampling is containerized in 55-gallon steel drums pending characterization and disposal in accordance with Station radiological controls and waste management programs. In accordance with the modified sampling program, groundwater samples are analyzed for tritium, major cations and anions, and gamma-emitting isotopes. Analysis of groundwater samples collected from the Station Monitoring Wells will also include a single event analysis for groundwater age determination (by tritium - helium-3 age dating). S
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey Technetium-99 and iodine-1 29 are also planned for analysis as appropriate to determine the source of the water. Analysis of groundwater samples for technetium-99 was not proposed in the June 2003 RIWP; however, analysis of groundwater samples was expanded to include this constituent due to a delay in obtaining analytical results for iodine-129. Technetium-99 will serve as a surrogate for iodine-129 pending the receipt of the iodine-129 analytical results from the analytical research laboratory (Purdue University). A detailed description of the use of technetium-99 as a surrogate is provided in Appendix B. Analytical results of groundwater samples collected to date from the Station monitoring wells are discussed in Section 3.5. 2.3 Aquifer Testing ARCADIS collected slug test data from Monitoring Wells N, 0, and U in August 2003. The purpose of the slug tests was to obtain estimates of hydraulic conductivity for the structural fill encountered within the cofferdam, and to obtain a preliminary estimate of hydraulic conductivity for the hydraulic fill and riverbed deposits. An extended pumping test will be performed to obtain a more refined estimate of the hydraulic conductivity and other aquifer parameters for the shallow, water-table aquifer outside of the cofferdam including the hydraulic fill and riverbed sands and gravel. Details regarding the proposed pumping test are included in Section 5.3. The slug tests were performed by first programming and installing an In-Situo miniTROLL-30 PSIA pressure transducer and data logger (miniTROLL) in the test well. Programming the miniTROLLs consisted of entering the test start time (projected to be approximately 15 minutes following installation of the miniTROLLs into the test well) and data collection interval (minimum of 1.5 seconds). Following installation of the miniTROLL into the test well, the water level in the well was allowed to stabilize. (If the water level had stabilized by the time the miniTROLL was scheduled to start recording data, the slug was introduced to the well. If the water level had not stabilized, the water level was allowed to stabilize before introducing the slug.) The slug that was used for the tests is a three-foot long, one and a half (1.5) inch diameter, solid Schedule 80 PVC rod. In a two-inch diameter well, the slug will displace the water table approximately 1.7 feet (i.e., 0.27 gallons). Upon introducing the slug to the test well to start the falling head test, the time and depth to water were recorded. During the test, the depth to water was periodically recorded to compare the water-level readings recorded by the miniTROLL. Once the water table had recovered to within 90 percent of static, the slug was removed to start the rising head test. Again, depth to water measurements and the time were recorded initially after removing the slug and periodically during the test. The test was considered complete once the water table had recovered to within 90 percent of static. The same process was repeated for each test well. An analysis of the slug test data and results are presented in Section 3.4. 6

The miniTROLLs were programmed to record data on 1 5-minute intervals throughout the period of record. In addition to the water-level information from the wells, actual tidal data from the Reedy Point, Delaware tidal station (USGS Station No. 8551910), and precipitation data from the weather station located approximately 0.9 miles east of the Salem Generating Station were obtained. i_ Following completion of the tests, the data were downloaded from the miniTROLLs and evaluated using Win-Situ software. The tidal data from Reedy Point and precipitation data obtained from the Station were also evaluated. An analysis of the tidal evaluation data and results are presented in Section 3.4. 7
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey 3 Hydrogeologic Evaluation The following sections provide the details and results of a review of regional and site-specific information regarding the geology and hydrogeology of the Station and surrounding area. The information was obtained to refine the preliminary conceptual model regarding groundwater flow dynamics at the Station and evaluate how groundwater flow influences the potential migration of tritium. The information reviewed included: 1) published information regarding regional geology and hydrogeology - Section 3.1; 2) information regarding local geology and hydrogeology prior to the construction of the facility - Section 3.2; 3) information regarding the construction of the facility - Section 3.3; and 4) an evaluation of the current hydrogeologic conditions at the Station - Section 3.4. 3.1 Regional Geology and Hydrogeology The Salem Generating Station is located on the east edge of the Delaware River, seven miles north of the Delaware Bay, eight miles southeast of the City of Salem and about 40 miles south of Philadelphia, Pennsylvania. The Station is located in the Atlantic Coastal Plain Physiographic Province, approximately 19 miles southeast of the contact between the coastal plain sediments and the Appalachian Highlands. This area is characterized by relatively flat to gently undulating terrain, underlain by unconsolidated sediments that increase in thickness to the southeast The coastal plain sediments were deposited in marine and non-marine environments. The sediments are between 1,500 and 2,000 feet thick in the vicinity of the Station, and unconformably overlie bedrock. These sediments range in age from Holocene to Cretaceous (0 to 146 million years old), and are comprised of clay, silt, sand, and gravel. Published geologic mapping indicates that the basement rock beneath these sediments (in the area of the Station) is'metamorphic schist of the Wissahickon Formation, which is Pre-Cambrian in age (570 to 900 million years old) (USGS 1999). The shallow, water-table aquifer at the Station consists of approximately 25 to 35 feet of dredge spoils (hydraulic fill), structural fill material, tidal marsh deposits and riverbed deposits. The structural fill replaced the dredge spoils and natural deposits in select locations at the facility during construction of the Station. Additional information regarding the construction of the facility and the composition and nature of the structural fill are provided in Section 3.4. The geologic formations beneath the water-table aquifer, in order of increasing depth, are as follows: the clay, confining-unit; the Vincentown Formation; the Homerstown-Navesink Aquitard; the Mount Laurel-Wenonah Formations; the Matawan Formation; the Magothy Formation; the Raritan Confining Unit and Aquifer, the Potomac Group; and, the Wissahickon Formation. Regional cross sections trending northeast to southwest (A-A') 8
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancocks Bridge, New Jersey parallel to the Delaware River, and northwest to southeast (B-B') perpendicular to the river are provided on Figure 3 (USGS 1999). The following sections describe in more detail the units of the coastal plain sediments that are encountered in the vicinity of the Station. 3.1.1 Hydraulic Fill Artificial Island is composed largely of hydraulically placed dredge spoils from construction and maintenance activities of nearby navigational channels. The hydraulic fill is not considered a source of drinking water. 3.1.2 Riverbed Deposits A relatively thin layer of sand and gravel underlies the more recent native and anthropogenic deposits composing Artificial Island. The layer consists of an approximate five-to ten-foot layer of discontinuous Quaternary Age riverbed deposits. The sand and gravel layer appears as a discrete deposit in some borings (Wells U and V). The results of aquifer tests have shown the riverbed deposits to have a hydraulic conductivity on the order of 0.0I to I ft/day (Dames & Moore 1988, 1974). 3.1.3 Clay, Confining-Unit The Vincentown Formation is separated from the hydraulic fill and riverbed deposits of the water-table aquifer by a clay, confining-unit. This unit consists of gray clay with trace silt and gravel, and in the area of the investigation is laterally extensive. Conflicting geologic reports suggest that the clay, confining-unit is either the Miocene Kirkwood Formation, or the Pleistocene Van Sciver Lake Bed deposits (USGS 1979 and 1999). As discussed in Section 5.4, a sample of the clay will be submitted for pollen analysis to determine the age of the clay unit. L Boring logs prepared for studies conducted prior to and during construction of the Station were reviewed to determine if the clay, confining-unit is laterally extensive beneath the Station. The boring logs indicated that the clay unit was encountered in each the boring advanced to a sufficient depth. A contour map of the surface elevation for the unit was prepared and is presented on Figure 4. 3.1.4 Vincentown Formation The Vincentown Formation is an aquifer of minor importance in some areas. In the vicinity of the Station, the Vincentown Formation has chloride concentrations of 1,800 to 4,300 mg/L preventing the aquifer from being used as a potable water source. (Dames & 9
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey Moore 1988). The Vincentown Formation outcrops over a small area of central Salem County, and trends northeast-southwest and dips to the east-southeast. The Vincentown Formation is composed of sands to silty sand characterized by a glauconitic quality. Confined by the overlying clay unit, the Vincentown Formation extends southeast from Keasby Creek to Stow Creek with the greatest thickness (approximately 60 feet) coinciding with Alloways Creek (USGS 1999). The Vincentown thins and narrows to the northeast reaching a minimum thickness between Glassboro and Berlin before again increasing in thickness and lateral extent. The results of aquifer and laboratory tests have shown the Vincentown Formation to have a hydraulic conductivity on the order of I to 10 ft/day (USGS 1999; Dames & Moore 1988). The Vincentown formation is underlain by the Homerstown-Navesink Aquitard. 3.1.5 Homerstown-Navesink Aquitard The Homerstown-Navesink Aquitard is considered to be part of a composite confining unit that includes the less permeable portions of the Vincentown and Piney Point Formations. The aquitard is composed of clayey to silty glauconitic green and black sands with a relatively low permeability (USGS 1999). The results of aquifer tests indicate that the Homerstown-Navesink Aquitard has a vertical hydraulic conductivity on the order of 0.01 ft/day in Salem County (USGS 1999). Though not quantified, evidence exists indicating that leakage occurs from the Vincentown through the Homerstown-Navesink Aquitard to the underlying Mt. Laurel-Wenonah Aquifer (Dames & Moore 1988). 3.1.6 Mt. Laurel-Wenonah Aquifer The Mt. Laurel-Wenonah Aquifer is considered to be a major aquifer for the region and is composed of slightly glauconitic sand and increasing silt with depth. The Mt. Laurel-Wenonah aquifer is also identified as existing in Delaware by the Delaware Geological Survey (DGS). The depth to the top of the Mt. Laurel-Wenonah Aquifer is approximately 173 feet in the vicinity of the Station, with the outcrop area extending from slightly west of Salem and extending approximately halfway to Pennsville (Dames & Moore Decemberl 6, 1968; USGS 1999). The aquifer has a strike of northeast-southwest and dips to the east-southeast. The maximum thickness of the aquifer is approximately parallel to strike and is coincident with Williamstown and Stow Creek. The results of aquifer tests have shown the Mt. Laurel-Wenonah Aquifer to have a hydraulic conductivity on the order of 0.01 to 10 ft/day and a storativity on the order of Ix10-5 to lxlO (USGS 1999). The Mt. Laurel-Wenonah Aquifer is underlain by the Matawan Aquitard. 3.1.7 Matawan Aquitard The Matawan Aquitard is a composite unit including the Woodbury Clay and Merchantville Formations. The aquitard is predominantly composed of micaceous and 10
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey glauconitic clay with some sand present. This unit is a major aquitard, conforming to regional strike and dip that may contain a thin water bearing sand in some areas. The New Jersey Geologic Survey (1995) defined the leakance of the aquitard as being on the order of Ix101' to 1x10 4 feetlday/foot (day') in Salem and Gloucester Counties with the greater values in the western portions of the counties. The Matawan Aquitard is the confining unit for the Magothy Aquifer. 3.1.8 Magothy Aquifer The Magothy Aquifer is composed of fine to coarse-grained sand with local beds of dark gray lignitic clay, and is located at a depth of 445 feet with a thickness of 50 to 100 feet in the vicinity of the Station (Dames & Moore Decemberl 6, 1968; USGS 1999). The Magothy outcrops just west of Pennsville with the outcrop area following the regional strike of the coastal plain sediments. The Magothy Aquifer dips and thickens to the southeast (USGS 1999), and has been documented by the DGS as existing in Delaware. The results of aquifer tests have shown the Magothy to have a hydraulic conductivity on the order of 100 ft/day and a storativity on the order of lxi C3 (USGS 1999; NJGS 1995). The Magothy Formation is separated from the Raritan Formation by an unnamed confining unit. 3.1.9 Raritan Confining Unit The confining unit separating the Magothy and Raritan aquifers is composed primarily of dense clay at an approximate depth of 490 feet with a thickness of 190 feet including a 22-foot thick sand unit (Dames & Moore Decemberl6, 1968; 1988). A leakance on the order of 10" day', increasing up dip, has been used by the NJGS (1995) to characterize the movement of water through the confining unit to the underlying Raritan Aquifer. 3.1.10 Raritan Formation The Raritan Formation is composed of sand with traces of silt and occasional lenses of clay appear with increasing frequency down dip. The Raritan is a major aquifer for the region conforming to the regional strike and dip (USGS 1999). The Raritan Aquifer consists of two sandy zones beneath the Station. The first is the 22-foot thick sand mentioned above at a depth of 688 feet often identified with the Raritan Confining Unit. The second includes a 35-and a 24-foot sand located at depths of 766 and 811 feet bgs, respectively (Dames & Moore December 16, 1968). The total thickness of the Raritan Aquifer has not been well quantified in eastern New Jersey (USGS 1999); however, it tends to thicken down dip, has an approximate thickness of 100 feet beneath the Station, and its maximum identified thickness occurs between Pennsville and Salem. The results of aquifer tests have shown the hydraulic conductivity of the Raritan Formation to be on the order of 1 to 1,000 ft/ day and storativity to be on the order of lx1 0'3 to Ix1O (USGS 1999; Dames & Moore 1988). II
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear. LLC Salem Generating Station Hancock's Bridge. New Jersey The Raritan Formation is separated from the Potomac Group by a discontinuous confining unit (USGS 1999). 3.1.11 Potomac Group The Potomac Group is an undifferentiated series of gravel, sand, silt and clay layers separated from the Raritan in some areas by a confining unit. Down dip, the Raritan and Potomac are undifferentiated (USGS 1983). The Potomac Formation is thought to be more than 250 feet thick and is located at a depth of approximately 836 feet beneath the Station with the uppermost sand occurring at 860 feet below ground surface (Dames & Moore Decemberl6, 1968; USGS 1999). The results of aquifer tests in Gloucester County have shown the group to have a hydraulic conductivity on the order of 100 fl/day and a storativity on the order of lx0 5to 1x104 (Barksdale et al. 1958). The Potomac Group is underlain by Pre-Cretaceous bedrock of the Wissahickon Formation (USGS 1999) 3.1.12 Wissahickon Formation Located at a depth of approximately 1,400 feet, the Wissahickon Formation is primarily composed of metamorphic gneiss and schist (Hardt and Hilton 1969). The bedrock is not considered a significant source of groundwater. 3.2 Local Hydrogeology - Pre Construction The Station is located on the southern tip of what was once a natural bar projecting into the Delaware River. The groundwater flow conditions present in the natural bar would have been typical of those present on any island composed of unconsolidated materials. Water would move away from the axis of the bar in either direction with semi-radial flow occurring at the ends of the bar. The area between the bar and the mainland had been formerly used as a dredge spoil area. In 1899, a timber sheetpile wall was installed around the perimeter of the bar. Over the next 50 or so years the area was used as a spoil area for material obtained during the dredging of the Delaware River. Riprap was added to the perimeter when the timbers began to degrade (Dames & Moore February 1974, June 1977). The area landward of Artificial Island has remained a tidal marsh. 3.3 Facility Construction The construction of the facility has resulted in significant changes in the local hydrogeology. It was necessary to remove and rework much of the soil in the area of investigation in order to facilitate construction. This construction process was guided in part by the recommendation of the geotechnical investigation of Artificial Island (Dames 12
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey and Moore August 28, 1968). This study recommended that the containment, fuel handling and auxiliary buildings be constructed upon a foundation mat placed at a depth of 50 to 70 feet bgs in the Vincentown Formation and recommended that the turbine, service and administration buildings be placed on pilings driven into the Vincentown Formation. This section describes the facility construction, which has had a significant impact on local hydrogeology in the area of the investigation. Facility construction details are highlighted on cross section diagrams through various Station features (Figures 5 through 9) Cofferdam Construction The recommendations for the containment, fuel handling and auxiliary buildings were implemented by first constructing a cellular cofferdam of welded interlocking sheet piling filled with lean concrete. The extent of the cofferdam is shown on Figure 2 and in profile on Figures 5 and 6. The elevation of the base of the cofferdam is uniform at approximately 20 feet plant datum (PD), or -69.92 feet above mean sea level (amsl -NAVD 1988). The elevation of the top of the cofferdam is 78 feet PD (-11.92 feet amsl) on the north, south and west sides. The elevation of the eastern side is 64 feet PD (-25.92 feet amsl) providing access and a foundation for the return circulating water pipes and associated thrust block. Within the cofferdam, soil was dewatered and excavated to approximately 30 feet PD (- 59.92 feet amsl) and lean concrete was poured, providing the foundation for the containment vessels, fuel handling buildings, and the auxiliary building. The elevation of the bottom of the foundation was designed to be completed into the Vincentown Formation. During construction, 15 borings were completed within the cofferdam through the clay, confining-unit and 20 feet into the Vincentown Formation in order to determine the elevation of the top of the Vincentown Formation. When the surface of the Vincentown Formation was reached, the area was cleared of loose soil and lean concrete was poured directly onto the exposed Vincentown Formation. Because the latter stages of the excavation were performed in freezing temperatures, a layer of material was left in place to insulate the Vincentown Formation until the concrete was ready to pour. In cases where the top of the Vincentown Formation did freeze prior to pouring of the concrete, the frozen soils were excavated or thawed prior to starting the pour. Following the pouring of the lean concrete, test borings were completed through the concrete to verify that the mat was founded upon the Vincentown Formation. The lean concrete mat is between 5 and 10 feet thick with its top elevation between 35 and 40 feet PD (-54.92 to -49.92 feet amsl) (Dames & Moore April 9, 1969). The soils removed from within the cofferdam were not used to backfill the completed structure. The hydraulically placed fill underlying Artificial Island does not meet the building design specifications for the Station. Therefore, it was necessary to import construction or structural fill to build the facility. The structural fill was placed between and around the Auxiliary Building, Fuel Handling Buildings, Units I and 2, portions of the cofferdam, above the return circulating water pipes, and from the top of the clay, confining 13
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey unit to the land surface in the portions of the area between the cofferdam and the circulating water discharge pipes. This material was used extensively in the area of Unit I and the circulation water pipes. Service Water Intake Construction The service water intake structure, shown on Figure 2, was constructed by driving sheet pile into the Vincentown Formation, and dewatering and excavating the enclosed soils (Dames & Moore August 28, 1968). The foundation of the structure lies upon a lean concrete pour placed upon the top of the Vincentown Formation. The base of the lean concrete is at elevation 45 to 50 feet PD (-44.92 to -39.92 feet amsl) (Dames & Moore June 3, 1970). This structure extends from the top of the clay, confining unit to the land surface preventing groundwater flow from this area to the Delaware River. Construction of service water pipes The original material in the locations of the service water pipes was excavated to the top of the riverbed deposits that overly the clay, confining-unit. Structural backfill was placed above the riverbed deposits. The structural fill was compacted to 98 percent of optimum and used as the foundation for the service water lines (Dames & Moore August 28, 1968). Compaction is the process of increasing soil unit weight by forcing soil solids into a tighter state and reducing soil voids. This process strengthens soils and reduces hydraulic conductivity. Optimum compaction is the maximum soil weight that can be achieved at a given moisture content. The service water lines are two-foot diameter and are located at varying depths below ground surface throughout the area of investigation. The location of the lines is shown on Figure 2. Circulating Water Intake Construction The circulating water intake structure is shown on Figure 2. The area of the intakes for the circulating water pipes was dredged to elevation 56 feet PD (-33.92 feet amsl). The surrounding structure was constructed on piles cut off at elevation 56 feet PD (-33.92 feet amsl). The top of the Vincentown Formation in this area is between elevation 40 and 53 feet PD (-49.92 and -36.92 feet arnsl) (Dames & Moore June 3, 1970). This structure extends from the top of the clay, confining-unit to the land surface preventing groundwater flow from this area to the Delaware River. Construction of the circulating water pipes Water in the circulating water system is drawn from near shore, through 12, 7-foot diameter water intake lines. Water passes through the turbine building and returns to the Delaware River through 6, 11.9-foot diameter pipes extending approximately 500-feet off shore and discharging at an elevation of 53 feet PD (-36.92 feet amsl). The location of the lines is shown on Figure 2. The return circulation water lines are an important subsurface feature affecting groundwater flow in the area of investigation. They were constructed by sheet 14
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey piling and excavation dewatering of the overlying sediments to the top of the Kirkwood Formation. Concrete footers were constructed perpendicular to the pipes from the turbine building to the shoreline. Between the concrete footers, crushed compacted concrete was placed. The surface of this foundation is sloped uniformly from an elevation of approximately 65 feet PD (-24.92 feet amsl) near the shore to about 75 feet PD (-14.92 feet amsl) near the turbine building. Following construction, lean concrete was poured between the pipes. These pipes and underlying foundations are a buried flow barrier, extending vertically 15 to 20 feet from the top of the clay, confining unit limiting southward groundwater movement. Construction of the return circulation water pipes were completed by placement and compaction of structural fill from near the top of the pipes to the present land surface. Sheet Pile - Circulating Water Intake Structure to the Service Water Intake Structure Groundwater movement toward the Delaware River is also restricted between the Circulating Water and the Service Water Intake Structures by interlocking sheet pile. The sheet piling is considered to be good barrier to flow as cathodic protection is used to control corrosion. The sheet piling was driven through the surficial aquifer into the first aquitard beneath Artificial Island (the clay, confining unit) during construction of the Salem Generating Station. The sheet piling is located as shown on Figure 9. Where the sheet piling is indicated using a dark black line, the elevation of the top is above the current water table; the sheet piling acts as a dam limiting the horizontal movement of water. Where the sheet piling is indicated using a gray line, the elevation of the top is below the current water table; groundwater is moving across the top of the sheet piling toward the Delaware River. 3.4 Local Geology and Hydrogeology - Current The construction of the Salem Generating Station has caused significant changes to the local geology and hydrogeology. Within the footprint of the cofferdam surrounding Units I and 2, 100 percent of original Artificial Island materials and structures was removed to a depth of 70 feet. Beyond the limits of the cofferdam, sheet piling was driven into the clay, confining-unit and left in place, portions of the riverbed deposits were excavated and replaced with structural fill, other portions of the riverbed deposits were chemically grouted (see Figure 8, Station Cross Section E-E') thereby changing their physical properties, and the foundations of structures, utilities, as well as various buried piping systems, extend below the water table affecting groundwater flow. Each of these issues is discussed in further detail below concerning their potential influence on groundwater flow and transport. 15
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey 3.4.1 Local Geology Documents produced during the design and construction of the Station were used in conjunction with data obtained during the site investigation to define the geology as it currently exists. The Station geology is tied into the regional geology via the Vincentown Formation. During construction many areas were excavated down to the top of the Vincentown Formation, as such, it is a logical reference point. In the vicinity of the Station, the Vincentown Formation is overlain by the clay, confining-unit, the riverbed deposits, hydraulically placed dredge spoils, and in some locations structural backfill. In most cases, the properties of these formations have been described in the above sections. The upper surface of the Vincentown Formation is located at approximately 35 feet PD (-55.53 feet amsl). The Vincentown is composed of glauconitic sands to silty sands with varying degrees of calcite cementation. Pumping tests conducted in the Vincentown Formation have shown the unit to have a hydraulic conductivity on the order of Ix10-3 cm/s (2.8 feet/day) and a storativity with a magnitude on the order of lxl04 to Ix10'3 (Dames & Moore May 23, 1974). The Vincentown Formation is overlain by the clay, confining-unit. The clay, confining unit extends from the top of the Vincentown Formation to approximately 60 feet PD (-30.53 feet amsl). The clay, confining-unit is composed of tan to gray clay with trace silt and gravel, and ranges in thickness from ten to twenty feet. The clay, confining-unit is overlain by the riverbed deposits of the shallow, water-table aquifer. The riverbed deposits are laterally discontinuous at the Station. When encountered, the riverbed deposits vary in content from a dense, dark gray to tan, fine to medium sand with varying gravel content to a dark gray silt and fine sand. With an upper elevation of approximately 65 feet PD (-25.53 feet amsl), the riverbed deposits range in thickness from approximately I to 9 feet. The riverbed deposits are overlain by hydraulic fill in some areas and structural fill in others, and is considered a leaky confined aquifer (Dames & Moore February 27, 1981 and December 23, 1992). The hydraulic fill is a dark gray estuarial silt and clay with a hydraulic conductivity 1,000 to 10,000 times less than the underlying riverbed deposits (Dames & Moore December 23, 1992). The hydraulic fill extends approximately from an elevation of 35 feet PD (-55.53 feet arnsl) to surface grade in areas that remained undisturbed during the construction of the generating station. In other areas, the hydraulic fill has been entirely removed and replaced with structural fill. The structural fill used at the site was obtained from a number of sources in New Jersey and Delaware. One fill source used in the area of this investigation was the Hinchner Pit. While the location of the borrow source was not identified, the material was described as 16
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Brdge, New Jersey yellowish-brown fine to medium sand with a trace of silt and clay (Dames & Moore June 20, 1972). 3.4.2 Local Hydrogeology The following sections provide the details and results of the site-specific hydrogeologic investigation activities conducted following the submittal of the June 2003 RIWP. These activities include the evaluation of groundwater flow conditions at the site based on current groundwater elevation data from Station monitoring wells; the results of the slug tests performed on Monitoring Wells N, 0, and U; and the results of the tidal evaluation. 3.4.2.1 Groundwater Flow ARCADIS personnel performed site-wide monitoring well gauging events on June 26, July 29, and August 15,2003. The depth-to-water in each well was measured relative to the top L of the well casing using an electronic water-level indicator. Using the gauging measurements and the surveyed top of casing elevations, groundwater elevations were calculated for each well. Table 3 provides a summary of the groundwater elevation data. As summarized in Table 3, groundwater elevations in the shallow, water-table aquifer ranged from a local high of 6.85 feet amsl in Monitoring Well R to 2.94 feet ams in Monitoring Well W. Groundwater elevations in the Vincentown Formation ranged from a local high of 1.66 feet amsl in Monitoring Well V to 1.37 feet arnsl in Monitoring Well Q. Although water-table elevations decreased (the average water-table elevations decreased approximately 0.4 feet from June to August), the relative groundwater elevations between the hydrogeologic units measured on July 29 and August 15 are consistent with the June 26 measurements. The measurements indicate that the hydraulic head in the Vincentown Formation is approximately four feet lower than the hydraulic head in the shallow, water-table aquifer. A groundwater elevation contour map for the shallow, water-table aquifer based on the June 26, 2003 data is presented on Figure 10. As shown on the figure, groundwater flow is generally from the center of the island (northeast of the Salem Generating Station) towards the Delaware River. Due to permeability differences between the structural fill and the hydraulic fill, groundwater is mounded within the area of the cofferdam. Groundwater flows radially outward from the cofferdam, and the observed mounding effect dissipates quickly. It should be noted that there is incomplete data between Well S and the Delaware River. Eight additional monitoring wells will be installed in this area (Section 5), and a revised groundwater elevation contour map will be prepared that reflects the influence of the facility construction on groundwater flow. A groundwater elevation contour map for the Vincentown Formation was not prepared Water level data collected from monitoring wells screened in the Vincentown Formation 17
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey suggest that the potentiometric surface of this unit is relatively flatWater levels in the Vincentown Formation are tidally influenced, varying by approximately 4 feet each tide cycle (see Section 3.4.2.3 - Tidal Evaluation Results). These water-level changes, combined with the distance between monitoring wells makes the collection of a synoptic round of water-level data difficult. To more accurately assess groundwater flow conditions in these wells, data logging pressure transducers will be installed in these wells to collect synoptic water levels (see Section 5.3.2) and a groundwater elevation contour map for this unit will be prepared. 3.4.2.2 Slug Test Results Slug tests were performed on Monitoring Wells N, 0, and U to quantify hydraulic properties in the unconfined aquifer. The field procedure followed for these tests are discussed in Section 2.3. The slug test data generated from these wells were evaluated using the Bouwer and Rice (1976) method. The primary assumptions ofthis analysis are:
- 1) the flow field is steady and laminar near the well; 2) the aquifer is homogenous and isotropic within the zone of influence; and 3) the well screen is clean.
Table 4 provides a summary of the hydraulic conductivity values estimated from the slug tests. Plots of the slug test analyses are provided in Appendix C. Monitoring Wells N and 0 are screened in the structural fill. The estimated hydraulic conductivity at Well N is between 0.09 and 0.14 ftl/day. The estimated hydraulic conductivity at Well 0 is between 3.6 and 4.3 f/day. The variation in hydraulic conductivity between wells reflects not only differences between soils and well construction, but also slug test procedures in general. Slug tests displace only a small volume of water in the vicinity of the well, thereby stressing only a small portion of the aquifer. The discrepancy between sampling points is not atypical. The estimated hydraulic conductivity value for Monitoring Well U screened in the riverbed deposits was 2.95 fl/day. 3.4.2.3 Tidal Evaluation Results The results of the tidal investigation were consistent with previous tidal studies (Dames & Moore January 4, 1968). Approximately four feet of tidal response was observed in Well L (screened within the Vincentown Formation). Well W, screened within the shallow, water-table aquifer, showed a negligible tidal response. Similarly, Well M, located within the cofferdam on the west end of the Salem Unit One Fuel Handling Building exhibited no discernable tidal response. These tidal data indicate that the Kirkwood Aquitard effectively isolates the riverbed deposits from tidal fluctuations in the Vincentown Formation and there are no tidal influences in the aquifer where tritium has been detected. Plots depicting the tidal evaluation analyses are provided in Appendix D. 18

In accordance with the sampling program initiated following the installation of Monitoring Wells K through R, and the modified sampling program initiated following the installation of Monitoring Wells S through W, groundwater samples have been collected on a periodic basis to assess groundwater quality inside and outside of the cofferdam. The groundwater samples are analyzed by Maplewood Testing Services or Salem Chemistry for tritium, sodium, boron, and gamma-emitting isotopes. Analysis of groundwater samples collected from the Station Monitoring Wells also included a one-time analysis for groundwater age determination (by tritium - helium-3), technetium-99, and iodine-129. These analyses are performed by the research analytical laboratories (University of Rochester and Purdue University). Analytical results of the groundwater age determination for Monitoring Wells K, L, P, Q, U and T are presented below. Groundwater age determination results for the remaining wells, as well as iodine-129 and technetium-99 analytical results for the wells are pending. These results will be presented in the comprehensive RIR. The analytical results of groundwater samples collected through August 2003 are summarized in Table 5, indicate the following: > Well K - Tritium has not been detected in groundwater samples collected from Monitoring Well K at concentrations above the further investigation criterion (3,000 pCiIL). Analytical results of groundwater samples collected from Monitoring Well K consistently indicate tritium concentrations between 500 and 1,200 pCi/L. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Well K. Analytical results of the groundwater age analysis for Well K suggest that tritiated water (at concentrations estimated to be 3,000 to 5,000 pCi/L) from Station operations recharged with rainwater from the surface approximately 20 years ago and migrated to the Vincentown Formation. Sk Well L - Tritium has not been detected in groundwater samples collected from Monitoring Well L at concentrations above the further investigation criterion (3,000 pCi/L). Analytical results of groundwater samples collected from Monitoring Well L consistently indicate tritium concentrations below the laboratory detection limit. Gamma-emitting isotopes, other than those considered naturally occurring, have not been detected. Analytical results of the groundwater age analysis combined with the results of low-level tritium analysis indicate that 19
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancocks Bridge, New Jersey groundwater in the vicinity of Well L recharged approximately 21 years ago with rainwater from the surface with tritium concentrations (45 pCiIL) equivalent to local precipitation 20 to 25 years ago. > Well M - Prior to the replacement of Monitoring Well M (a %-inch diameter push point) in May 2003, tritium concentrations detected in groundwater samples collected from Well M indicated a steady decrease in concentrations from 18,700 pCi/L on February 12, 2003 to 8,800 pCi/L on April 30, 2003. Following the installation of replacement Well M (a l-inch diameter well with 10 feet of slotted well screen), analytical results of groundwater samples collected from the well have indicated tritium concentrations ranging from 126,000 pCi/L to 73,200 pCi/L. Boron and gamma-emitting isotopes have not been detected above concentrations associated with background levels. > Well N - Initial groundwater samples collected from Monitoring Well N indicated concentrations of tritium above the further action criterion for tritium (20,000 pCi/L). A groundwater sample collected from Monitoring Well N on January 30, 2003 indicated a concentration of tritium of 69,000 pCi/L. Since then, concentrations oftritium have declined to approximately 5,000 pCi/L, which is below the further action criterion. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Monitoring Well N. > Well 0 - Analytical results of groundwater samples collected from Monitoring Well 0 have consistently indicated concentrations of tritium above the further investigation criterion. Analytical results of groundwater samples collected from Monitoring Well 0 indicate tritium concentrations between 1,220 and 13,400 pCi/L. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Monitoring Well 0. > Well P - Tritium has not been detected in groundwater samples collected from Monitoring Well P at concentrations above the further investigation criterion (3,000 pCi/L). Analytical results of groundwater samples collected from Monitoring Well P indicate tritium concentrations between 465 pCi/L and the laboratory detection limit. Analytical results of the groundwater age determination, which provides analytical results for tritium at a much lower detection limit, indicate a tritium concentration of 60 pCi/L and a recharge date of approximately 13 years. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Monitoring Well P. 20
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey > Well Q -Tritium has not been detected in groundwater samples collected from Monitoring Well Q at concentrations above the further investigation criteria (3,000 pCi/L). Analytical results of groundwater samples collected from Monitoring Well Q indicate tritium concentrations below the laboratory detection limit. Analytical results of the groundwater age determination indicate a tritium concentration near the detection limit of 1.5 pCilL indicating that this groundwater recharged close to the onset of the nuclear era (circa 1950). Dissolved methane concentrations indicated by the groundwater sample collected from Well Q suggest that recharge occurred within the marshes that border the plant to the north. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Monitoring Well Q. > Well R - Historically, analytical results of groundwater samples collected from Monitoring Well R have indicated concentrations of tritium at or above the further investigation criterion. Tritium concentrations in groundwater samples from Monitoring Well R have steadily decreased from 13,900 pCi/L on February 26, 2003 to 2,860 pCilL on August 6,2003. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Monitoring Well R. > Well S - Analytical results of the groundwater sample collected from Monitoring Well S on July 9, 2003 indicated a tritium concentration of 3,530,000 pCi/L. In addition, analytical results of the groundwater sample indicated a boron concentration of 57.4 milligrams per liter (mg/L). The boron and tritium concentrations detected in the groundwater sample collected from Monitoring Well S are indicative of a release of primary water (i.e., water that has come in direct contact with fissionable material) such as the Spent Fuel Pool or ">d-waste". > Well T - Tritium has not been detected in groundwater samples collected from Monitoring Well T at concentrations above the further investigation criterion (3,000 pCi/b). Analytical results of groundwater samples collected from Monitoring Well T indicate tritium concentrations below the laboratory detection limit. Similar to Well Q, analytical results of groundwater samples collected from Well T indicate a methane concentration and a low concentration of dissolved air (15 percent of solubility) that suggest recharge from the marshes located to the north and east of the Station. The groundwater age determination indicates that the groundwater is typical of New Jersey precipitation from approximately 5 years ago. A more accurate assessment of groundwater age will be provided pending the results of the low-level tritium analysis. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Monitoring Well T. 21
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey > Well U - Tritium has not been detected in groundwater samples collected from Monitoring Well U at concentrations above the further investigation criterion (3,000 pCi/L). Analytical results of groundwater samples collected from Monitoring Well U indicate tritium concentrations between 146 pCiIL (estimated) and the laboratory detection limit. Similar to Wells Q and T, analytical results of groundwater samples collected from Well U indicate a methane concentration and a low concentration of dissolved air (15 percent of solubility) that suggest recharge from the marshes located to the north and east of the Station. The groundwater age determination indicates that the groundwater is typical of New Jersey precipitation from approximately 5 years ago. A more accurate assessment of groundwater age will be provided pending the results of the low-level tritium analysis. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Monitoring Well U. > Well V - Tritium has not been detected in groundwater samples collected from Monitoring Well V at concentrations above the further investigation criterion (3,000 pCi/L). Analytical results of groundwater samples collected from Monitoring Well V indicate tritium concentrations between 285 pCiIL and 334 pCi/L. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Monitoring Well V. >o Well W - Analytical results of groundwater samples collected from Monitoring Well W have indicated tritium concentrations above the further investigation criterion. Analytical results of groundwater samples collected from Monitoring Well W indicate tritium concentrations between 11,100 and 11,500 pCiVL. Boron and gamma-emitting isotopes, other than at concentrations associated with background, have not been detected in groundwater samples collected from Monitoring Well W. Analytical results of the groundwater samples indicate that tritium has been detected above 3,000 pCi/L (the Interim Further Investigation Criterion for Tritium - see Section 4.2.3) in groundwater samples collected from Monitoring Wells M, N, 0, and R installed within the limits of the cofferdam, and Monitoring Wells S and W installed in the shallow, water-table aquifer outside of the cofferdam. Analytical results of groundwater samples collected from monitoring wells screened in the Vincentown Formation (Wells L, P. Q, and V) do not indicate that tritium from the Salem Generating Station Unit-I has migrated beyond the shallow, water-table aquifer. Well K indicates that tritium in groundwater in the vicinity of this well recharged with rainwater approximately 20 years ago. Analytical results of groundwater samples collected from Monitoring Well M, Monitoring Well S, and previously Monitoring Well N have indicated concentrations of tritium above 22
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey the New Jersey Groundwater Quality Criterion (GWQC) for tritium of 20,000 pCi/L. With the exception of Monitoring Well S, analytical results of these groundwater samples have not indicated concentrations of boron or gamma-emitting isotopes that would indicate that a source of primary water, such as the Spent Fuel Pool, is the likely source. The source of this tritium is still being investigated. Analytical results of the groundwater sample collected from Monitoring Well S indicate a tritium and boron concentration that are typical of a diluted release from a primary water source such as the Spent Fuel Pool or "rad-waste". Analysis for iodine-129 and/or technetium-99 will be used to further evaluate the potential source of tritium detected in Well S. 23
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey 4 Supplemental Groundwater Investigation 4.1 Objectives In an effort to characterize groundwater in the vicinity of Monitoring Well S and to investigate the source of tritium and boron detected in groundwater samples collected from L the well, a supplemental groundwater investigation was initiated. The objectives of the supplemental groundwater investigation were to: 1) determine if the tritium (and potentially other radionuclides) indicated by the groundwater sample collected from Monitoring Well S was discharging to the river; 2) delineate the vertical and horizontal extent of the tritium in groundwater in the vicinity of Monitoring Well S; and 3) evaluate the potential sources of tritium in Monitoring Well S. To achieve the objectives of the supplemental investigation, the groundwater sampling program was expanded significantly. The expanded groundwater sampling program consisted of the collection of grab groundwater samples from various depths at locations along the Delaware River, and surrounding Well S. The samples were then submitted for analysis for tritium, boron, and gamma-emitting isotopes. The groundwater sampling program designed to achieve the objectives of the investigation consisted of the collection of three proposed groundwater samples from discrete intervals in 37 proposed borings. The locations of the borings are shown on Figure 12. The specific purposes of the proposed borings are as follows: > Borings through 8 were proposed along the Station boundary with the Delaware River. The purpose of the borings was to evaluate concentrations of tritium and other analytes in groundwater as it approached the Delaware River from potential sources identified at the Station. > Borings 9 through 18 and Borings 31 through 37 were proposed for the vicinity of Station infrastructure identified as possible sources of tritium in groundwater. These potential sources include the "rad-waste" line, the Unit I Spent Fuel Pool,'the Unit I refueling water storage tank, and the Unit primary water storage tank. > Borings 19 through 30 were proposed in the vicinity and downgradient of Well S to evaluate the extent of tritium indicated by groundwater samples collected from the well. The following sections provide the details and results of the field implementation and analytical results obtained through the implementation of the supplemental groundwater investigation. 24
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey 4.2 Field Implementation The supplemental groundwater investigation was initiated in July 2003 following the detection of tritium in Monitoring Well S. As stated previously, the objectives of the supplemental investigation were to determine if tritium, as indicated by Well S, is migrating beyond the property boundary of the Station with the Delaware River and to E_ assess the lateral and vertical extent and potential sources of the tritium in groundwater. Borings were advanced at the locations shown on Figure 12 using truck mounted Hurricanes direct-push drilling equipment to the sample target depths. The Hurricane* rig was operated by ADT Diamond Drilling, Inc. of Neptune, New Jersey. Prior to advancing the borings, Underground Services, Inc. of West Chester, Pennsylvania cleared the borings to a depth of ten feet below ground surface using SoftDig! technology (a vacuum excavation system). Subsurface structures, which prohibited the advancement of borings, were encountered in the locations of Borings 5, 6, 11, 16, 17, 21, and 29 through the use of SoftDig!. In these circumstances, attempts to advance the borings were abandoned. Once cleared, groundwater samples were collected from the borings through the use of a Geoprobet SP-1 5 screened point sampler advance to select target depths. Typically, the target depths for the collection of groundwater samples were as follows: 1) 11 to 15 feet below ground surface; 2) 21 to 25 feet below ground surface; and, 3) 31 to 35 feet below ground surface. These target intervals were chosen to evaluate groundwater at or near the water table surface, in the riverbed deposits or other sediments encountered just above the clay, confining-unit, and some intermediate sample interval. The target sample intervals were modified in the field based on field conditions and observations, as necessary. In several locations, the shallower target intervals (11 to 15 and 21 to 25) yielded too little groundwater to collect a sufficient volume of water for analysis. In these locations, one-inch diameter Schedule 40 PVC temporary wells were installed to facilitate the collection of groundwater. The temporary wells were installed using two and a quarter inch diameter Geoprobe well installation rods with an expendable point. Drilling equipment and sampling devices (e.g., the SP-1 5 sampler) were decontaminated between sample locations. Maplewood Testing Services personnel (Maplewood) collected the groundwater samples using peristaltic pumps. New sample tubing was used at each sample location to prevent cross contamination between sample locations. A sufficient volume of water was collected from each sample location to analyze for tritium. Groundwater samples were collected from select borings to be analyzed for major cations and anions and gamma emitting isotopes. Groundwater samples from several borings advanced within the limits of the cofferdam (Borings 33 through 37) were collected for iodine-129, technetium-99 and helium-3 analyses. 25
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey The groundwater samples were submitted to the Salem Generating Station Chemistry Department (Chemistry) for initial screening for tritium. If groundwater samples did not indicate a concentration of tritium above the Station Chemistry lower level of detection (LLD), the sample was sent to the Maplewood laboratory for analysis using more sensitive equipment. The samples collected for iodine-129, technetium-99, and helium-3 analysis were submitted to a research analytical laboratory at the University of Rochester (see QAPP June 2003, and addendum to work plan) for analysis. The advancement and subsequent sampling of 30 out of the 37 proposed borings was completed successfully. Table 6 presents a summary of the details of the supplemental groundwater investigation. The results of the investigation are presented in the following section. 4.3 Results The laboratory analytical results for the existing monitoring well network and the supplemental groundwater investigation are shown on Figure 12 and summarized in Tables 5 and 7, respectively. Groundwater analytical results for samples collected from the borings advanced along the property boundary with the Delaware River demonstrate that there has not been a release of tritium or gamma-emitting isotopes to the river. In addition, the groundwater analytical results for samples collected from borings located at the southern and eastern limits of the supplemental investigation generally define the extent of groundwater containing tritium; however, the results of the supplemental investigation have identified an expanded area in the vicinity of Monitoring Well S with elevated levels of tritium in groundwater. This area of groundwater has been identified on Figure 12 as an area with tritium levels above 500,000 pCi/L. This area is proposed to have continued monitoring, additional well installation, and expanded investigation to further characterize groundwater conditions and potential source(s). The recent investigation was not able to complete a pathway between a potential source of primary water and Well S. The details of the additional investigation, designed to meet this objective, are presented in Section 5 below. As indicated by groundwater samples collected from Monitoring Well M, elevated levels of tritiated groundwater were detected at the west end of the Unit I Fuel Handling Building. This water in contrast to the groundwater in the vicinity of Well S has low levels of boron, potentially indicating a different source (i.e., different tritium/boron ratios for Wells S and M). Facility operations have indicated that historically the Unit I primary water storage tank has overflowed. The water in the primary water storage tank contains deionized water from the Unit 1 Spent Fuel Pool (i.e., boron and gamma-emitting radioisotopes have been removed leaving only tritiated water). Historical releases from the primary water storage tank are a potential source of tritium in groundwater within the vicinity of Monitoring Well M. Information concerning historical releases of water from the Unit I primary water 26
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey storage tank is currently being investigated. The results of the investigation will be reported in the final remedial investigation report. Analytical results for technetium-99 and iodine-129 will be used to further evaluate potential sources of tritium indicated by Well M. The primary objective of the groundwater investigation, as discussed in Section 1.2, is to determine whether water from the Unit 1 Spent Fuel Pool that accumulated in the Styrofoam-filled seismic gap migrated beyond the seismic gap and into soils contacting the gap. Monitoring Wells R and N were installed at the north and south ends of the seismic gap, respectively, to assess this pathway. The chemistry and water-level data indicate that there has not been a release of water from the north side of the seismic gap. This conclusion is based upon two sets of data. First, tritium concentrations in Well R, which is located less than five feet from the north end of the seismic gap, are less than 5,000 pCi/L. Second, water-level elevations in Well R are at least two feet higher than in Well N; if both ends of the seismic gap are in contact with foundation soils, groundwater may be flowing into the north end of the gap and out of the south end of the gap. Further assessment of potential leakage from the south end of the seismic gap will be made following installation of an additional monitoring well near the south end of the seismic gap (see Section 5.1 -Proposed Well AC). Analytical results of groundwater samples collected from this well, in addition to the results of iodine-129 and technetium-99 sampling, will be used in an effort to complete a final assessment. 5 Proposed Groundwater Investigation Activities 5.1 Well Installation Fifteen additional monitoring wells (Wells Y, Z, and AA through AM) will be installed at various locations around the Salem Generating Station (monitoring well installation activities are being conducted concurrently with the preparation and submission of this report). The collection and analysis of groundwater samples from the additional monitoring wells will provide supplemental data regarding the extent of tritium in groundwater and the rate of groundwater movement in the riverbed deposits. Water-level measurements from the monitoring wells will be evaluated to determine the direction of groundwater flow at the Station both inside and outside of the cofferdam. The locations of the additional groundwater monitoring wells are shown on Figure 13. The purposes for the additional monitoring wells are as follows: Monitoring Wells Y and Z are being installed in the locations of supplemental investigation Borings I and 3, respectively. These wells are being installed to characterize groundwater quality and flow conditions in an area downgradient of the Salem Generating Station Unit I Spent Fuel Pool between the cofferdam and the Delaware River. 27
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey a Monitoring Wells AA and AB are being installed in the locations of supplemental investigation Borings 13 and 20, respectively. These wells are being installed to characterize groundwater quality and flow conditions in an area south and southeast of Monitoring Well S. Monitoring Well AC is being installed near the location of supplemental investigation Boring 35, as close to the Styrofoam-filled seismic gap as practical. This well is being installed to characterize groundwater quality and flow conditions directly south of the Styrofoam-filled seismic gap and to the east of the Unit I equipment hatch. Monitoring Wells AD, AJ and AK are being installed at various locations outside of the cofferdam and within the area of groundwater containing tritium to further characterize groundwater quality and flow conditions in the vicinity of the wells. These wells will also be used for performing pump tests to evaluate various aquifer parameters (see Section 53), and potentially may be incorporated into a remedial action designed to capture the groundwater containing tritium. Monitoring Well AE is being installed in the location of supplemental investigation Boring 37. This well is being installed in a location east of the Salem Generating Station Unit 1 to characterize groundwater quality and flow conditions in this area. Monitoring Well AF is being installed in the location of supplemental investigation Boring 18. This well is being installed to characterize groundwater quality and flow conditions in an area south of the circulating water discharge pipes. Monitoring Wells AG and AH are being installed in the locations of supplemental investigation Borings 7 and 8, respectively. These wells are being installed to characterize groundwater quality and flow conditions in an area downgradient of the Salem Generating Station Unit I Spent Fuel Pool and in the vicinity of the circulation water discharge pipes. Monitoring Well Al is being installed in the location of supplemental investigation Boring 9. This well is being installed to further characterize groundwater quality and flow conditions within the cofferdam. Following installation, a pump test will be performed on this well to further characterize aquifer parameters, and to evaluate potential remedial alternatives for the tritium in groundwater (e.g., capture of the tritiated water through pumping and permitted discharge). Monitoring Well AL is being installed in the location of supplemental investigation Boring 30. This well is being installed to characterize groundwater quality and 28
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey flow conditions south of the Salem Generating Station Unit I Spent Fuel Pool and the circulation water discharge pipes. Monitoring Well AM is being installed near the location of supplemental investigation Boring 34, as close to the Styrofoam-filled seismic gap as practical. This well is being installed to characterize groundwater quality and flow conditions directly south of the Styrofoam-filled seismic gap and to the west of the Unit 1 equipment hatch. 5.1.1 Proposed Well Details The proposed monitoring wells will be installed using the hollow stem auger drilling method and, with the exception of proposed Monitoring Wells AD, Al, AJ, AK, and AM, will be constructed of two-inch diameter Schedule 40 PVC well screen and riser. To facilitate the performance of pumping tests, and in anticipation of potentially utilizing these wells as groundwater extraction wells, Monitoring Wells AD, Al, AJ, AK, and AM, will be constructed of nominal four-inch or six-inch diameter Schedule 40 PVC. A sand filter pack will be placed in the annular space around each screen interval followed by an appropriate bentonite seal and grouting material. Monitoring Well AD will be completed at ground surface with a two-foot by two-foot steel well vault/access manway. The remaining monitoring wells will be completed at ground surface with stickup steel protective casings. A summary of the proposed well completion details (i.e., total depth, screened interval) is presented in Table 8. The total depth and screen interval for the proposed wells have been determined based on depth restrictions imposed by the facility construction and a review of geologic logs and recent groundwater analytical data for existing monitoring wells. Actual construction details of the wells may vary depending on field observations and soils encountered during the installation of the monitoring wells. NJDEP Bureau of Water Allocation Monitoring Well Records and well construction logs will be prepared following the completion of the monitoring wells. The proposed monitoring wells located outside of the cofferdam will be screened above the clay, confining-unit and, will monitor water in the riverbed deposits, if present. The proposed monitoring wells located within the limits of the cofferdam will be installed to depths corresponding with the top of the lean concrete installed in this area. Analytical results of groundwater samples collected from Monitoring Well S and from supplemental investigation Borings 33, 34, and 35 suggest that the concentrations of tritium in groundwater varies with depth within the cofferdam with the highest concentrations of tritium being detected directly above the lean concrete. 29
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey 5.1.2 Well Permits All wells will be installed per the requirements of NJ.A.C. 7:9D, Well Construction; Maintenance and Sealing of Abandoned Wells, October 4, 2001, by aNew Jersey-licensed well driller. Prior to installation of the wells, monitoring well permits will be obtained from the NJDEP. 5.1.3 Soil Lithology In accordance with NJ.A.C. 7:26E-4.4(g) [4], split-spoon samples will be logged at least every five feet, at any change in soil lithology, and at zones that indicate obvious signs of contamination. The split-spoon sampling will be conducted as follows: Split-spoon samples will be collected on five-foot centers throughout the borings. Continuous split-spoon samples will be collected from the riverbed deposits to the top of the Kirkwood Aquitard. L The soils encountered in the split-spoon samples and Macrocore0 samples will be logged by an ARCADIS geologist, and soil boring logs will be prepared. 5.1.4 Well Development In accordance with N.J.A.C. 7:26E-4A(g) [8], the proposed monitoring wells will be developed to yield a non-turbid discharge, where possible, following installation. The monitoring wells will be developed using a combination of surging and pumping techniques. Care will be taken during the development (and sampling) of the wells near the seismic gap to minimize drawdown in these wells. 5.1.5 Survey In accordance with NJA.C. 7:26E-4.4(g) [7], the Station monitoring wells will be surveyed by a New Jersey-licensed surveyor following installation as follows: The inner well casing will be surveyed to the nearest hundredth (0.01) foot in relation to the permanent, on-site datum and horizontally to an accuracy of one-tenth of a second latitude and longitude relative to the New Jersey State Planar Coordinate System. A permanent water-level measurement mark will be etched onto the top of the inner well casing to allow for accurate, consistent and comparable water-level measurements over time. 30
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey Following completion of the survey, the surveyor will complete a Monitoring Well Certification Form B for submittal to the NJDEP. A summary of the proposed well completion details (i.e., total depth, open borehole interval) is presented in Table 8.. 5.2 Modified Monitoring Well Sampling and Analysis Schedule Following the installation of the proposed monitoring wells, a groundwater sampling program will be initiated. The groundwater sampling program will involve the collection and analysis of groundwater samples from the monitoring well network and the collection of water-level measurements. The following sections provide details regarding these activities. 5.2.1 Water-Level Measurements Additional rounds of synoptic water levels will be collected from the Station monitoring well network to further assess groundwater flow conditions. The groundwater flow measurements collected from the wells will be analyzed to determine relative hydraulic heads between and among the various formations at the Station, to evaluate groundwater velocity between the cofferdam and river in the shallow, water-table aquifer, and to evaluate the influence of the Station construction on groundwater flow dynamics. Groundwater measurements will be collected in a manner consistent with the standard operating procedure in the June 2003 QAPP. 5.2.2 Collection and Analysis of Groundwater Samples Following the installation and development of the proposed monitoring wells, the existing sampling program will be modified to include the new wells. A summary of the sampling and analysis schedule is provided in Table 9. Groundwater samples will be collected and analyzed using the procedures and methods outlined in the QAPP. The groundwater samples will also be analyzed for technetium-99. As stated previously, Technetium-99 will serve as a surrogate for iodine-129 pending the receipt of the iodine-129 analytical results from the analytical research laboratory (Purdue University). Appendix B provides details regarding the use of technetium-99 as a surrogate for iodine-129. 5.3 Additional Aquifer Characterization Additional aquifer characterization activities will include the performance of pump tests on several monitoring wells to evaluate aquifer parameters (e.g., hydraulic conductivity), and to evaluate groundwater flow direction and gradient in the Vincentown Aquifer. Following installation,pumping tests will be performed on Monitoring Wells AD, Al, AJ, AK and 31
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancocks Bridge, New Jersey AM. The pumping tests will include the performance of step drawdown tests to determine appropriate pumping rates, followed by the performance of eight-hour constant-rate pumping test (6-hours pumping followed by 2 hours of recovery). In addition to monitoring water level in the pumping well, water-level measurements will be monitored in adjacent monitoring wells throughout the test duration. The aquifer test data will be analyzed using AQTESOLV for Windows (HydroSOLVE, 1996), a software package designed for the analysis of various aquifer tests. 5.3.1 Pumping Test Procedures Hydrogeologic testing will include conducting step-drawdown tests and constant-rate pumping tests on Monitoring Wells AD, Al, AJ, AK and AM. The following sections provide the procedures that will be followed during the performance of the pumping test. 5.3.1.1 Step Drawdown Test The procedures for performing the step drawdown test are as follows: Il. The static water level in the test well and observation wells will be initially measured using an electronic water level indicator.
- 2.
A Grundfoss redi-flow electric submersible pump will be installed within the test well (Well AD). Effluent will be handled and disposed of in accordance with Station's programs. The pump will be capable of yielding flow rates from 2 to 20 gallons per minute (gpm). A ball valve and totalizing flow meter will be used to control and adjust flow rates and document the rate of discharge. The depth to the pump intake level will be recorded prior to starting the test.
- 3. A maximum of four "steps", or varying flow rates will be conducted until drawdown stabilizes, as necessary. Anticipated flow rates will be 0.5, 1, 2, and 4 gpm; however, flow rates will be modified in the field based on field observations.
- 4. During the step drawdown tests, drawdown will be measured in adjacent monitoring wells using data-logging pressure transducers to evaluate the influence of pumping on the aquifer.
- 5. A specific capacity will be calculated for each step using the following equation:
Specific capacity = Q step/s step
- where, Specific capacity is measured in gallons/minute/foot, 32
Initial Groundwater Investigation Report and Remedial Investigation Work Plan Addendum ARCADIS PSEG Nuclear, LLC Salem Generating Station Hancock's Bridge, New Jersey
- and, Q step = Flow rate for each step, in gpm.
s step Drawdown for each step, in feet.
- 6. By analyzing the specific capacity, drawdown, required water volume, depth of pump installation, other hydrogeologic factors, and the rate for the constant-rate pumping test will be determined.
The data collected during the constant-rate pumping test will ultimately be used to calculate the aquifer characteristics such as hydraulic conductivity and other useful parameters. The following field procedures will be implemented: 5.3.1.2 Constant-Rate Pumping Test The following procedures will be followed while performing the constant-rate pump test:
- 1. Following a minimum 12-hour stabilization period after the step test, an initial round of static water-level measurements will be collected from the pumping well and other monitoring wells located within the vicinity of the pumping well. In addition, electronic data loggers will be set up in a "background" well (Well U) located on site but away from the pumping well to record ambient water levels throughout the entire pumping and recovery testing.
- 2. An electronic in-well data logger will be calibrated and installed in the pumping well.
The data logger will record water-level measurements in the well following the start of the test.
- 3. A Grundfoso redi-flow electric submersible pump will be installed within the pump test well. Effluent will be handled and disposed of in accordance with Station programs.
The pump will be capable of yielding flow rates from 0.5 to 10 gallons per minute (gpm). A ball valve and totalizing flow meter will be used to control and adjust flow rates and document the rate of discharge. The depth to the pump intake level will be recorded prior to starting the test.
- 4. Pumping will then commence at the constant rate chosen based on the results of the step-drawdown test. The data logger will record water-level measurements on a frequent basis in the monitoring well throughout the 6-hour constant pumping duration and 2 hours after the end of the test or until water levels return to static conditions.
- 5. Water-level measurements will be monitored in adjacent monitoring wells throughout the test duration.

The results of the aquifer test analysis will be described in detail in the Remedial Investigation Report (RIR). The RIR will also document any data corrections and will contain figures that document the curve matching procedure used to analyze the test data. 5.3.2 Water-Level Monitoring - Vincentown Formation As discussed in Section 3.42.3, water-levels in the Vincentown Formation are tidally influenced, varying by approximately 4 feet each tide cycle. To more accurately assess groundwater flow conditions in these wells, data logging pressure transducers will be installed in Monitoring Wells K, L, P, Q, and V for a one-week period to facilitate the collection of synoptic water levels. Tidal data obtained from an onsite tide station will also be obtained for the corresponding time period. The data obtained from the wells and tide station will be used to more accurately assess groundwater flow direction and gradient in the Vincentown Formation. 5.4 Age Determination - Clay, Confining-Unit To determine the relative age of the clay, confining-unit that separates the riverbed deposits and the Vincentown Formation, samples of the clay obtained during the drilling of Monitoring Well V will be submitted to Lehigh University for pollen analysis. If the clay unit is determined to be Miocene in age based on the results of the pollen analysis, the interpretation would be the clay is from the Kirkwood Formation. If the clay unit is determined to be Pleistocene in age based on the pollen analysis, the clay would be interpreted as the Van Sciver Lake Bed Deposits. 6 Revised Remedial Investigation Schedule The anticipated schedule for the implementation of the activities outlined above is provided in Figure 14. The schedule will be modified as necessary based on comments from the NJDEP-BNE and the results of investigation activities. Updates to the schedule will be provided, as necessary. 7 References ARCADIS, June 2003; Remedial Investigation Work Plan, PSEG Nuclear LLC, Salem Generating Station, Hancock's Bridge, New Jersey.

L ARCADIS L~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ U.. L Appendix B Technetium-99 Analysis L
Appendix B Technetium-99 Analysis L Prepared for PSEG by Robert J. Poreda Professor of Environmental Sciences University of Rochester L September 15, 2003
Appendix B This project will use state-of-the-art methods to determine the abundance and distribution of Technetium-99 in the Salem I plant environment. Technetium-99 (99Tc) is a radioactive by-product of nuclear power generation (in addition to other mostly "nuclear" sources). Recent analytical advances in inductively-coupled plasma mass spectrometry (ICP-MS) make it possible to detect sub-picogram (less than 1010 atoms) quantities of 99Tc. Ve will apply these methods to understanding the migration of 99Tc in the environment. 99Tc levels have not been accurately monitored in low-level radioactive settings because of difficulties in detection nor have the pathways of migration in the environment been determined. One major focus of the research plan is to understand the migration of radionuclides (especially 99Tc and 1291) through the groundwater/soil environment. At Rochester, Professor Udo Fehn and his students have developed and tested the state of the art methods for the determination of 1291. These analyses were successfully used at Ginna to establish the integrity of the containment system that minimized the radionuclide migration from the site. The behavior of Tc in groundwater and its interaction with soils suggests that the mobility of Tc-99 is nearly equivalent to 1-129 and tritium. The geochemistry of Tc is such that it exists as an oxyanion, TcO4, and has limited adsorption onto soils. Thus Tc-99 could be readily adopted as a fingerprint for spent fuel pool water with the added benefit of lower analytical costs and more rapid sample throughput than 1-129 (only the Purdue accelerator can achieve the LLDs necessary for this investigation). Technetium (Tc) was detected in 1937 by C. Perrier and E. Segre in a deuteron-irradiated molybdenum sample in the cyclotron of E.O. Lawrence in California. Minute quantities of 99Tc (half life = 2.14 x 105yr.) are found to occur naturally as a result of spontaneous fission of uranium in uranium ore bodies. However, the largest source of the weakly radioactive isotope, '9 Tc, is from the fission of uranium in nuclear reactors. Technetium from nuclear power generating stations makes up about 6 percent of uranium fission products (Peacock, 1973), and together with 1291, represents the major long-lived radio-isotopes generated in the nuclear industry. Federal regulations (I OCFR61...) specify the 99Tc and 1291 activity levels for disposal in low-level radioactive burial sites, although most waste shipments over-estimate the activity (by as much as I OOx) and simply report the 99Tc and 1291 levels as "upper limit values". Technetium differs from most of the radionuclides associated with the nuclear industry (9 0 Sr, 137CS, 60Co, 63Ni) that have half lives of 30 years or less and decay to less than 0.01 percent of their original activity in 300 years (the monitoring/evaluation interval). Because of the long half life, 99Tc in environmental samples is not easily measured by conventional low level counting techniques. Typical detection limit for 99Tc, obtained by I
Appendix B counting, is about 20 pCi/L of water (or 1013 atoms of 99Tc). ICP-MS techniques should push this limit down by more than OOOx. The technetium from 1000 ml of water is collected on a TEVA disc specifically designed to adsorb Tc. The Tc is eluted from the disc with ultra-pure 2N HCI and 18 MQ water to a total volume of 10 ml. At a conservative sensitivity of 100,000 cps/ppb, a signal of 100 cps is equivalent to a concentration in the water of 0.0 Ippt or about 0.2 pCi/L. The University of Rochester has established a world-class facility for the detection of extremely low levels of environmental metals, including 99Tc, using plasma source mass spectrometry. In the 1990s, the commercialization of mass spectrometers with ICP sources and quadrupole analyzers has revolutionized the study of trace element geochemistry and environmental chemistry. These instruments have extremely low detection limits (ppt or better) due to the efficiency of the ICP source in ionizing transition metals. In addition, sample preparation is simplified compared to other analytical methods because samples are introduced to the instrument as aqueous solutions. The plasma source mass spectrometry laboratory at the University of Rochester includes a new generation Thermo X-7 instrument, and a VG Plasma 54. The X-7 is a workhorse quadrupole mass spectrometer with exceptional sensitivity and stability for trace metal detection at the ppt level. 2
