eoogic Associates <br /> Geologists, Hydrogeologists and Engineers <br /> July 27,2006 <br /> JN: 2003-021 <br /> Mr. Ross Atkinson <br /> Central Valley Regional Water Quality Control Board <br /> 11020 Sun Center Drive, #200 <br /> Rancho Cordova, CA 95670-6114 <br /> SUBJECT: SECOND QUARTER 2006 MONITORING REPORT <br /> FRENCH CAMP LANDFILL <br /> SAN JOAQUIN COUNTY, CALIFORNIA <br /> On behalf of Forward, Inc. (Forward), GeoLogic Associates is pleased to submit the second <br /> quarter 2006 Monitoring Report for the French Camp Landfill, in compliance with the California <br /> Regional Water Quality Control Board- Central Valley Region(RWQCB)Waste Discharge <br /> Requirement(WDR) Order Number R5-2004-0159. <br /> This report summarizes standard observations and presents the results of surface-water and <br /> groundwater monitoring during the second quarter 2006. A summary of analytical results and <br /> time-series concentration plots for field and monitoring parameters are also included in this <br /> report. A description of field procedures and sampling protocols followed by personnel <br /> conducting field monitoring activities is included in Appendix B of the report. <br /> Groundwater quality conditions beneath the French Camp Landfill during the second quarter <br /> 2006 monitoring period are generally similar to those observed in previous monitoring periods. <br /> Currently,the French Camp Landfill is in the process of the final cover construction for closure. <br /> Groundwater quality conditions beneath the French Camp Landfill during the second quarter <br /> 2006 monitoring period are generally similar to those observed in previous monitoring periods. <br /> Several inorganic CLs were exceeded in DMP wells MW-8A and MW-9B. However,no <br /> statistically significant increasing trends were noted for constituent concentrations exceeding a <br /> CL and no VOCs were detected in DMP monitoring wells during the current monitoring period. <br /> The results of water quality analyses completed for leachate monitoring wells during the second <br /> quarter 2006 monitoring period indicate that eight VOCs were measured in leachate monitoring <br /> well MW-lA with three measured above the PQL. In addition, one estimated trace level VOC <br /> was detected in leachate monitoring well MW-2. <br /> 16885 W.
