bis(2-ethylhexyl)phthalate in all groundwater, leachate, and surface water samples. As discussed in Section 4.2,bis(2-ethylhexyl)pthalate is documented laboratory contaminant since a similar concentration was measured in the QA/QC method blank. Comparison of metal analytes with state or federal maximum contaminant levels(MCLs) (Tables 2 through 4) indicates that only arsenic, measured in the sample collected from background well MW-6A, exceeded an MCL. Given the fact that well MW-6A is a background well and is located several hundred feet from the site,the MCL exceedance does not appear to be related to a release from the landfill. 5.0 SOIL-PORE GAS MONITORING In accordance with WDR Order No. R5-2007-0046, soil-pore gas probes are monitored semiannually using a field screening protocol, where soil-pore gas samples are only collected if field screening indicates methane concentrations greater than 2.5 percent. During the monitoring period, field screening of soil-pore gas probes was conducted on August 18, 2008. As shown on Table 6, no methane was detected in any of the soil-pore gas probes, and as a result, no samples were collected. 6.0 ANNUAL SUMMARY 6.1 GENERAL During the 2008 monitoring year, groundwater elevation measurements were performed quarterly and water quality monitoring points were sampled semiannually in accordance with WDR Order No. R5-2007-0046. All of the monitoring points are sampled for the monitoring parameters summarized in Table 1. Time-series plots depicting groundwater and surface water constituent concentrations and a tabular summary of the historical monitoring are presented in Appendix D and an electronic format is included in Appendix C. Piper diagrams of the semiannual data obtained in 2008 are included in Appendix D, and hydrographs of the detection monitoring wells, illustrating historic groundwater elevations, well screen elevations, and pump intake elevations are also included in Appendix D. Discussions of the historical trends in constituent concentrations are presented in Section 4. 6.2 GROUNDWATER Groundwater elevations have remained relatively static over the past year, reflecting seasonal precipitation patterns. Groundwater generally flows south to southeast across the site at a gradient of approximately 0.0025 ft/ . Groundwater quality conditions beneath the French Camp Landfill during the 2008 monitoring year are generally similar to those observed in the previous monitoring year. Calculated CLs for the general chemistry parameters were generally exceeded in wells MW-9B and MW-l0A during the monitoring year, and pH values were generally D:\200&0012\FC_2SA08.doc 6 GeoLogic Associates
