FORW <br /> A LANDFILL 9999 S.Austin Road <br /> Manteca,CA 95336 <br /> (209)9824298,Fax(209)982-1009 <br /> October 28, 2013 <br /> JN: 2013-0021 <br /> Mr. Ross Atkinson <br /> Central Valley Regional Water Quality Control Board <br /> 11020 Sun Center Drive, Suite 200 <br /> Rancho Cordova, CA 95670-6114 <br /> SUBJECT: THIRD QUARTER 2013 <br /> WATER QUALITY MONITORING REPORT <br /> FORWARD LANDFILL <br /> SAN JOAQUIN COUNTY,CALIFORNIA <br /> Forward Incorporated(Forward) is pleased to submit the subject water quality monitoring report <br /> for the Forward Landfill in compliance with reporting requirements of the Regional Water <br /> Quality Control Board- Central Valley Region(RWQCB) Waste Discharge Requirements <br /> (WDRs) Order Number R5-2003-0049. This report presents quarterly sampling results for the <br /> reporting period dating from July 1 to September 30, 2013 (third quarter 2013). <br /> According to the Forward Landfill Operations Manager, standard observations have been <br /> conducted weekly during the reporting quarter. The Forward Landfill Operations Manager also <br /> reported that no surface water was discharged from the facility during the reporting period. <br /> During the third quarter 2013 monitoring period, no notices of violation were issued by the San <br /> Joaquin County Environmental Health Department. <br /> For the Forward Unit, environmental monitoring for the third quarter 2013 yielded results similar <br /> to previous quarters. Non-statistical exceedance for volatile organic compounds (VOCs) were <br /> identified at well MW-2A, and trend analyses indicate a statistically significant increasing <br /> temporal trend for diisopropyl ether at well MW-2A. For the inorganic monitoring parameters, <br /> concentration limits (CLs) were exceeded for constituent concentrations in wells MW-2A, MW- <br /> 13, MW-14, MW-15, MW-18, MW-19, and background wells MW-23R and MW-24. <br /> Statistically significant increasing temporal trends were identified for chloride concentrations in <br /> well MW-13, nitrate-N concentrations in well MW-14, sulfate concentrations in well MW-15, <br /> and sodium concentrations in wells MW-18 and MW-24. However,review of groundwater flow <br /> directions suggests that the increasing trends for organic and inorganic constituents may be <br /> related to changing conditions in background associated with agricultural activities. <br /> Surface water samples collected from the upstream and downstream surface water monitoring <br /> stations during the third quarter 2013 monitoring period are generally consistent with each other <br /> and no VOCs were detected. <br /> Groundwater quality conditions beneath the Austin Unit during the third quarter 2013 monitoring <br /> period are generally similar to historical results. Non-statistical exceedances for VOCs were <br /> identified at detection monitoring program (DMP) wells AMW-6 and AMW-13. Trend analyses <br />
