samples collected from this well did not confirm the presence of carbon disulfide. 0 Therefore,the carbon disulfide concentration measured in the primary sample was concluded to be a false positive. 6.4 SOIL-PORE GAS Pursuant to M&RP Order No. R5-2007-0046, soil-pore gas probes are monitored semiannually using a field screening protocol. During the 2009 monitoring year no methane was detected in any of the soil-pore gas probes. 6.5 COMPLIANCE RECORD During the 2009 monitoring year, no NOVs were issued by the LEA or CIWMB and the site is currently in compliance. However, in a letter dated October 23, 2009, the CIWMB indicated that the analytical data provided in the 2008-2009 Storm Water Annual Report exceeded US EPA benchmark values for total iron. A review of the storm water sampling program indicates that the samples were collected from the sedimentation basin and ponded stormwater was not discharged from the facility. In addition,historical water quality data indicate elevated (>1.0 mg/L) iron concentrations in background samples suggesting that the elevated iron concentrations measured in storinwater are naturally occurring. 7.0 SUMMARY Groundwater quality conditions beneath the French Camp Landfill during the monitoring period are generally similar to those observed in previous monitoring periods. CLs were exceeded for one or more constituents in the samples collected from wells MW-6A, MW-8A,MW-9A, MW-913 and MW-I OA, and with the exception of the chloride concentration measured in the sample collected from well MW-1 OA, none of the constituents that exceeded a CL exhibited a statistically significant increasing trend during the monitoring period. Previous statistical exceedances for chloride and TDS have been identified in samples from well MW-10A and a NRI) for groundwater monitoring well MW-I OA (Herst, 2005) concluded that the French Camp Landfill has been impacted by saltwater intrusion and the elevated chloride and TDS concentrations measured in well MW-I OA are believed to be the result of this condition and not the result of landfill-related impacts. Organic constituent results indicate that chloroform was measured above the PQL in the samples collected from background well MW-6A. However, the detection of chloroform in background well MW-6A is not believed to the result of a release from the landfill since background well MW-6A is located approximately 1200 feet cross-gradient from the landfill, and chloroform has been rarely detected in on-site wells. The results of water quality analyses completed from the surface-water monitoring stations are generally consistent with previous results. No VOCs were detected in the samples collected from the surface water stations during the monitoring period. A D:12008-0012\FC_2SA09.doc 8 GeoLogic Associates
