FORWARD LANDFILL 9999 S.Austin Road <br /> Manteca,C4 95336 <br /> (209)982-4298,Fax(209)982-1009 <br /> July 15,2013 <br /> J N: 2014-0012 <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: JANUARY—JUNE 2014 SEMIANNUAL <br /> WATER QUALITY MONITORING REPORT <br /> FRENCH CAMP LANDFILL <br /> SAN JOAQUIN COUNTY,CALIFORNIA <br /> Forward, Inc. (Forward) is pleased to submit the January through June 2014 semiannual <br /> monitoring report for the French Camp Landfill, in compliance with the California Regional <br /> Water Quality Control Board - Central Valley Region (RWQCB) Waste Discharge Requirement <br /> (WDR) Order Number RS-2007-0046. This report summarizes standard observations and <br /> presents the results of surface-water, groundwater, and soil-pore gas monitoring during the <br /> semiannual (January 1 through June 30,2014) monitoring period. <br /> During the monitoring period, no violations were issued for the facility. Groundwater quality <br /> conditions beneath the French Camp Landfill during the monitoring period are generally similar <br /> to those observed during previous monitoring periods. During the semiannual monitoring <br /> event, Concentration Limits (CLs) were exceeded for chloride at wells MW-913 and MW-10A; <br /> and for pH, specific conductance, and total dissolved solids at well MW-10A. However, no <br /> statistically significant increasing trends were calculated for constituents exceeding a CL. <br /> With the exception of the consistent detection of trichlorofluoromethane at well MW-9A and <br /> chloroform at well MW-6A, no volatile organic compounds (VOCs) were detected above a <br /> practical quantitation limit in groundwater samples collected during the monitoring period. In a <br /> letter dated June 23, 2014, the RWQCB was notified of a non-statistical exceedance at well <br /> MW-9B as the result of two VOCs measured at trace concentrations. Conformation sampling <br /> was performed in June 2014. No other VOCs were detected in groundwater samples. <br /> The field screening results from soil-pore gas monitoring probes indicates that methane was <br /> not detected at any French Camp Landfill soil-pore gas monitoring probe during the monitoring <br /> period. <br />
