## 1 INTRODUCTION
Background This groundwater monitoring report is designed to address the South Carolina Department of Health and Environmental Control (SCDHEC) per mit requirement for a groundwater monitoring program at the industrial waste landfill locat ed at Duke Power Company’s Catawba Nuclear Station. This report will also be included in the Annual Groundwater Monitoring Report that summarizes the groundwater quality and landfill impac ts to groundwater resources for the period July 1 2008 through June 30, 2009. Historically, groundwater quality has been sampl ed and water levels measured on a semi-annual frequency at four monitoring wells locations around the landfill (Wells LMW-1A, LMW-2, LMW-3, LMW-4). During 2004, Duke requested and re ceived approval from SCDHEC to replace monitoring wells LMW-2 and LMW-3 with new monitoring wells LMW-2A and LMW-3A. In 2008Duke requested and received approval to replace compliance well LMW-1A with new well LMW1B. LMW-1B was constructed in March 2008 and the initially sampled April 2008. Monitoring wells LMW-1A, LMW-2 and LMW-3 were retained to provide additional water elevation data. Additionally, four wells associated with t he LMW-1A area assessment were monitored. Assessment efforts to address volatile or ganic compounds detected in Catawba’s landfill monitoring wells began in 1999. Duke submitted a report to SCDHEC (Catawba Nuclear Station, Industrial Waste Landfill, Additional Assessment Efforts, March 3, 2004) which included recommendations for additional activities at the site. As recommended in the report, assessment monitoring wells LMW-5S, LMW-5D, GPMW-22P and GPMW-23P are sampled on the same schedule as landfill wells and analytical result s are included in this report (Appendix 2). Figure 1 indicates the locations of existing monitoring wells associated with the landfill. Objectives The objective of this groundwater monitoring report is to assess the impact of the landfill on groundwater resources. Specific objecti ves of this monitoring program include:

• Conduct groundwater monitoring at the monitori ng wells at the frequency stated in the permit. • Analyze the groundwater samples for the parameters listed in the permit. • Assess groundwater flow characteristics. • Assess the impact of the landfill on groundwater quality.
METHODS AND MATERIALS Sampling and Analysis Plan Groundwater is sampled in accordance with the Catawba Nuclear Station, Industrial Waste Landfill, Permit # 463303-1601, Groundwater Monitoring and Analysis Plan, prepared by Duke Power Company, August, 1996, (revis ed 3/97, 1/99, 5/99, 4/00, 9/01). On November 18, 2008 Duke submitted a Groundw ater Monitoring System Design Report to SCDHEC in compliance with new SC regulation 61- 107.9. Upon approval of the report, Duke will draft and submit a revised monitoring and analysis plan.

## 2 Ground Water Monitoring

• Water Level Measurements Prior to well purging, water levels were measured and recorded at each well (Appendix 1). The water levels were measured using a digital water level meter.

• Monitoring Well Purging The current monitoring well system consists of four wells, LMW-1B, LMW-2A, LMW-3A and LMW-4. Monitoring wells LMW-1A, LMW-2 and LMW-3 used for water elevation purposes only. Additionally, assessment monitoring wells LMW-5S, LMW-5D, GPMW-22P and GPMW-23P (installed down-gradient of monitoring well LMW-1A) were sampled in support of recommendations from the assessment effort in the LMW-1A area. Sampled monitoring wells, with the exception of GPM W-22P and GPMW-23P are installed with dedicated sampling systems. Samples were collected once field m easurements were stable over three consecutive well volumes (pH +/- 0.20 units va riation; temperature +/- 0.2 0 

## C; specific conductance +/- 10% variation), or the volume of the well was evacuat ed. Samples were collected for analysis of the parameters listed in Table 1.

• Sample Collection and Preservation Monitoring wells LMW-1B, LMW-2A, LMW-3A, LMW-4, LMW-5S and LMW-5D were sampled for all parameters indicated by the permit. Moni toring wells GPMW-22P and GPMW-23P were sampled for all parameters with the exception of radiological. Samples were collected in the order of the vo latilization sensitivit y of the parameters:

• pH (In-situ) • Specific Conductance (In-situ) • Volatile Organic Compounds • Nitrate-Nitrogen • Sulfate, Chloride • Radiological Sulfate, chloride and nitrate-nitrogen samples were stored on ice at 4 0 

## C. Radiological and metals samples were preserved with nitric acid. Volatile organics were preserved with HCL to a pH less than 2.0 and preserved on ice at 4 0 

## C. The samples were delivered to the analytical laboratory at Duke Energy's Environmental Center for analysis. Data Analysis Insitu analysis of pH, specif ic conductance and temperature were made with a Hydrolab Water Quality Analyzer (Hydrolab, Inc.) and samp les were analyzed using approved United States Environmental Protection A gency (USEPA) and SCDHEC methods. Groundwater contours (Figure 2) were created usi ng the Krigging Function for gridding option in the Surfer for Windows software (Golden Software, Inc.). The analysis of the chemistry data and assessment of the groundwater quality was made by comparing the data to the SC groundwater standards and to historical monitoring data. Data exceeding a groundwater standard was then addressed in more detail. All laboratory analytical data is included in Appendix 2.

## Groundwater elevations decreased as compar ed to levels recorded during the April 2008 monitoring period and have been trending downwar d since April 2004. The direction of groundwater flow generally trends in an east, nort heast direction across the landfill site. The hydraulic gradient measured from monitoring well LMW-4 to monitoring well LMW-2A is 0.0041 ft/ft. This gradient is consistent with historical values. Groundwater Chemistry During this sampling period the following parameters were sampled in accordance with the permit; Field and lab pH, specific conductance, temperature, chloride, Nitrate-nitrogen and sulfate. Volatile organic compounds (VOC’s) were also sampled as a condition of the groundwater assessment plan for VOC’s. Although not required for this sampling event, metals samples were collected to better evaluate gr oundwater chemistry. In general, groundwater chemistry was similar to that reported previously. Insitu and Inorganic Parameters: All parameters, except for pH (all wells) were within the limits established by SC R.61-68 groundwater standards (Table 1). Values for pH have historically been below the groundwater standard of 6.5 units and are similar to those report ed previously. The low pH is attributed to soil characteristics. Mercury at monitoring well LMW-5S (0.0018 mg/l) continues to be elevated and slightly below the SC R.61-68 groundwater standard (0.002 mg/l). Mercury values in LMW-5S have been erratic since sampling began in 2003 and appear to be related to seasonal fluctuations of groundwater el evation. Monitoring wells dow ngradient of LMW-5S (GPMW-22P and GPMW-23P) continue to be non-detect for mercury.

## 4 Volatile Organic Compounds: Volatile organic compounds detected in the October 2008 samples are summarized in Table 2. Detected compounds and concentrations in monitoring wells LMW-2A and LMW-5S are similar to past data and concentrations in new well LMW-1B are similar to historical values in LMW-1A. One organic compound (cis-1,2-Dichloroethene: 0. 65 ug/l) was detected in deep monitoring well LMW-5D. No organic compounds were detect ed in LMW-3A and GPMW-22P. Toluene was detected in GPMW-23P (0.5 ug/l) but was also detected in the field blank (0.63 ug/l). Although chlorinated solvent compounds continue to be detected in some wells, the presence of break-down compounds suggest that natural a ttenuation processes continue to degrade the parent compounds (PCE & TCE) Radiological Parameters: Radiological results are provided in Table 3.

SUMMARY and CONCLUSIONS Groundwater samples were collected on October 27, 2008 from monitoring wells around the landfill and analyzed for the parameters requir ed by the permit and in accordance with recommendations presented in Additional Assessm ent Report, March 3, 2004. Prior to the collection of samples, water level measurement s were made to determine the hydraulic gradient and direction of groundwater flow. Groundwater elevations generally decreased as compared to levels recorded during the April 2008 monitoring period. In general, groundwater quality around the landfill meets groundwater standards except for pH and some volatile organic compounds. Mercury continues to be elevated in monitoring well LMW-5S. Since monitoring wells downgradi ent of LMW-5S (GPMW-22P and GPMW-23P) continue to be non-detect for mercury, it is re commended that these three wells continue to be monitored semiannually for increasing trends or plume advancement. Organic data suggest that natural attenuation processes continue to degrade PCE and TCE in the LMW-1A area. This report will also be included in the annual groundwater monitoring report submitted to SCDHEC in July, 2009.
