3.0 SOLID WASTE MONITORING <br /> During the third quarter 2007 the French Camp Landfill did not receive waste and the site <br /> has been formally closed. (Appendix A). <br /> 4.0 WATER QUALITY MONITORING <br /> 4.1 SAMPLING AND LABORATORY ANALYSES <br /> All of the groundwater monitoring wells, soil-pore gas probes, and surface water <br /> monitoring points were sampled on August 20, 2007. Stream gauging was also <br /> performed on August 20,2007. Prior to collection of samples, depth-to-water <br /> measurements were recorded for all groundwater monitoring wells. <br /> A single sample set was collected from each sampling point(groundwater, leachate,and <br /> surface water)and analyzed for the parameters stipulated in RWQCB Order No. R5- <br /> 2007-0046, and summarized in Table 1. Water quality samples were also analyzed in the <br /> field for dissolved oxygen, turbidity, temperature, specific conductance, and pH and the <br /> field measurements were recorded on well data sheets. The groundwater monitoring <br /> wells and surface water monitoring points were sampled in accordance with the sampling <br /> and analysis procedures detailed in Appendix B. Well data sheets,raw laboratory data, <br /> certificates of analyses, and chain-of-custody records for the sampling program are <br /> included in Appendix C. The laboratory analyses and field results for groundwater wells, <br /> surface water sampling stations, and soil-pore gas sampling stations are summarized in <br /> Tables 2 through 6. <br /> 4.2 QA/QC RESULTS <br /> The QA/QC program completed for the third quarter 2007 water quality monitoring event <br /> included analyses of one duplicate sample, one field(ambient)blank, one trip blank, and <br /> one laboratory method blank. The trip, field, and laboratory method blanks were <br /> analyzed for volatile organic compounds(VOCs)by EPA Method 8260. In addition, one <br /> trip blank and one laboratory method blank were also included for soil-pore gas samples <br /> and analyzed for VOCs by EPA Method TO-15. No VOCs were detected in groundwater <br /> or soil-pore gas QA/QC blank samples during the third quarter 2007 monitoring period. <br /> A duplicate groundwater sample was collected from well MW-8A and was labeled <br /> MW-Dup. Duplicate groundwater test results are presented along with the primary data <br /> in Table 3. Comparison of the primary sample with the duplicate sample indicates good <br /> agreement(within 5%)for the water quality constituents. <br /> 1DA2007-0044TC_wm07.doc <br /> 2 <br /> Geologic Associates <br />
