conducted during the monitoring period and no areas of concern were noted (see signed <br /> "Certification Statement" located inside cover page, after the Table Of Contents in this <br /> report). <br /> 3.0 SOLID WASTE MONITORING <br /> The French Camp Landfill has been formally closed and no longer receives waste <br /> (Appendix A). <br /> 4.0 WATER QUALITY MONITORING <br /> 4.1 SAMPLING AND LABORATORY ANALYSES <br /> All of the groundwater monitoring wells were sampled on February 17, 2009 and surface <br /> water monitoring points were sampled on February 18, 2009. Quarterly depth-to-water <br /> and stream gauging was performed on February 17, and May 17, 2009. <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, as summarized in Table 1. Water quality samples were also analyzed in the <br /> field for dissolved oxygen,turbidity, temperature, specific conductance, and pH and these <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 quality assurance/quality control (QA/QC)program completed for the monitoring <br /> event included analyses of one duplicate sample, one field(ambient)blank, one trip <br /> blank, and laboratory method blanks. The trip and field blanks were analyzed for volatile <br /> organic compounds(VOCs)by EPA Method 8260,while the laboratory method blanks <br /> were analyzed for all of the analytes included in the monitoring program. During the <br /> monitoring period, no VOCs were detected in any of the QA/QC blanks. <br /> A duplicate groundwater sample was collected from well MW-2 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 and duplicate sample results, when both results <br /> are measurable concentrations above the practical quantitation limit(PQL) indicates good <br /> agreement(within 10%), except for nitrate as nitrogen, which was within 15%. <br /> D:\2009-0018\FC 1SA09.doc <br /> 2 Geologic Associates <br />
