Water quality monitoring data obtained from groundwater and wastewater facilities at the nuclear generating station in U.S. between 2003 and 2008 was evaluated to determine the impact wastewater facilities had on the ground water source. Most of the constituent concentrations were reported as non-detect or below the reporting limits of the method used. For the constituents for which exceedances were reported, geochemical data analysis tools were used to plot and determine changes in water quality at each location. Historical information and data were also gathered and compared to the recent data to determine the changes in the water chemistry (if any) since the nuclear station started its operations. Water quality in the wells down gradient of the wastewater facilities did not indicate any changes due to wastewater leaks. Graphical and statistical analyses and evaluation of peer-reviewed literature supported the conclusion that the exceedances were not caused by discharges from the nuclear facility, but were naturally occurring or caused by surrounding agricultural activity.
