exceedances for chloride and TDS have been identified in samples from well MW-l0A <br /> and a No Release Demonstration(NRD) for groundwater monitoring well MW-l0A was <br /> performed(Herst, 2005). The NRD concluded that French Camp Landfill, located within <br /> the central Stockton area, has been impacted by saltwater intrusion and the elevated <br /> chloride and TDS concentrations measured in well MW-10A are believed to be the result <br /> of this condition and not the result of landfill-related impacts. Since specific conductance <br /> and TDS values often mimic each other,the specific conductance exceedance is believed <br /> to the result of this same condition. <br /> The results of water quality analyses completed for leachate monitoring wells MW-IA ' <br /> and MW-2 identified 11 VOCs above the PQL in well MW-IA, while no VOCs were <br /> detected in the sample from well MW-2. <br /> The results of water quality analyses completed for surface-water monitoring stations are <br /> generally consistent with previous results. During the current.monitoring period, CL <br /> exceedances were noted for the barium concentration in the samples from stations SW-2 <br /> and SW-3. However, with the exception of turbidity in all three surface-water samples, <br /> no statistically significant increasing trends were noted. , <br /> 8.0 REFERENCES <br /> California Regional Water Quality Control Board, Central Valley Region, 2005, "Order <br /> No.R5-2004-0159 Waste Discharge Requirements for Forward Inc.
