observations were conducted during the monitoring period and no areas of concern were <br /> noted(see signed"Certification Statement" included in Appendix A). <br /> 3.0 SOLID WASTE MONITORING <br /> The French Camp Landfill has been formally closed and no longer receives waste. <br /> 4.0 WATER QUALITY MONITORING <br /> 4.1 SAMPLING AND LABORATORY ANALYSES <br /> All of the groundwater and leachate monitoring wells and surface water monitoring <br /> points were sampled between August 5 and 6, 2013. Quarterly depth-to-water and stream <br /> gauging were performed on August 5 and November 29, 2013. <br /> A single sample set was collected from each sampling point(groundwater,leachate, and <br /> surface water)and analyzed by BC Laboratories for the parameters stipulated in RWQCB <br /> Order No. R5-2007-0046, as summarized in Table 1. Water quality samples were also <br /> analyzed in the field for oxidation-reduction potential, turbidity,temperature, specific <br /> conductance, and pH and these field measurements were recorded on well data sheets. <br /> The groundwater and leachate monitoring wells and surface water monitoring points <br /> were sampled by Del-Tech Geotechnical Support Services (Del-Tech)in accordance with <br /> the sampling and analysis procedures detailed in Appendix B. Well data sheets,raw <br /> laboratory data,certificates of analyses, and chain-of-custody records for the sampling <br /> program are included in Appendix C. The laboratory analyses and field results for <br /> groundwater wells and surface water sampling stations are summarized in Tables 2 <br /> through 5. <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 trip blank sample, and laboratory <br /> method blanks. The trip blank was analyzed for VOCs by EPA method 826013. <br /> Laboratory method blanks are analyzed for all of the analytes included in the monitoring <br /> program. During the monitoring period, acetone was measured above the practical <br /> quantitation limit(PQL)in the trip blank sample. However, acetone was not detected in <br /> any of the primary samples collected during the monitoring period. In addition, trace <br /> concentrations of chloride and sodium were measured in one or more of the laboratory <br /> method blanks,though, these detections were at very low, trace concentrations that did <br /> not affect the interpretation of primary sample results. <br /> A duplicate sample was collected from well MW-7A and was labeled DUP. Duplicate <br /> test results are presented along with the primary data in Table 2. Comparison of the <br /> primary and duplicate sample results, when both results are measurable concentrations <br /> above the practical quantitation limit(PQL), indicates good agreement with a relative <br /> percent difference of less than 4 percent.
