(Forward) is pleased to submit the January through June 2015 semiannual <br /> monitoring report for the French Camp Landfill, in compliance with the California Regional <br /> Water Quality Control Board - Centra} Valley Region /RVVOC8\ Waste Discharge Requirement <br /> (VVDR) Order Number R5-2007-0046. This report summarizes standard observations and <br /> presents the results of surface-water, groundwater, and soil-pore gas monitoring during the <br /> -- <br /> semiannual (January 1through June ]O, 2UI5) 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 W1VV-913 and K4VV-I0A; for <br /> pH value at vve||s MVV-9A and MW-10A; and for specific conductance at well MVV-10A. <br /> However, no statistically significant increasing trends were calculated for constituents <br /> exceeding aCL. <br /> With the exception of the consistent detection of trichlorofluoromethane at well MW-9A and <br /> chloroform at well MVV-GA, no volatile organic compounds (VOCs) were detected above a <br /> practical quantitation limit ingroundwater samples collected during the monitoring period. <br /> The field screening results from soil-pore gas monitoring probes indicates that methane was <br /> only detected at one probe (SGP-2A) at the French Camp Landfill at a |ovv volumetric <br /> percentage of0.1Y6Vduring the monitoring period. <br /> The results of water quality analyses completed for surface-water monitoring stations are <br /> generally consistent with previous results. During the monitoring period, three VOCs related to <br /> drinking water disinfection (disinfection byproducts; triha|oroethanes) were detected at |ovx <br />
