## DISSUSSION: This semiannual groundwater monitoring report includes results for samples collected on October 26

‐ 27, 2010 at the Catawba Nuclear Station Class Two Landfill. The sampling was conducted in compliance with the requirements of R.61

‐ 107.19 and includes analytical results for historical monitoring wells, monitoring wells installed according to the Groundwater Assessment Plan (Duke Energy, June 2009) and an additional monitoring well (LMW

‐ 11) installed in response to the a request from SCDHEC (June 11, 2010 correspondence, Leblang to Rowland).
The current groundwater monitoring system for the landfill consists of the following wells. Monitoring Well Information

## With the exception of LMW

‐ 1A, LMW

‐ 2 and LMW

‐ 3, all wells were sampled for all R.61

‐ 107.19 Appendix III parameters during the October 2010 monitoring event. Although Duke Energy received relief from continued analysis of Appendix V parameters (October 21, 2010 correspondence, Leblang to Roland), wells that previously had detectable concentrations of Appendix V parameters were retested during the October 2010 monitoring for those parameters.

## 2 

## New well LMW

‐ 11 was sampled and analyzed for all Appendix III and Appendix V parameters. Additionally, LMW

‐ 2 was sampled for Appendix III organics parameters to further demonstrate
non ‐ presence of BTEX compounds.
Tables 1 though 4 present summaries of the analytical results associated with the October 2010 sampling. Tables 5 through 7 present comparisons of the data between semiannual events.
The next scheduled monitoring is April 2011.
