FORWARD LANDFTLL 9999 S.Austin Road <br /> Manteca,CA 95336 <br /> (209)992-4298,Fax(209)982-1009 <br /> July 25,2013 <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: SECOND QUARTER 2013 <br /> WATER QUALITY-MONITORING REPORT <br /> FORWARD LANDFILL <br /> SAN JOAQUIN COUNTY, CALIF ORINIA <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 April I to June 30, 2013 (second 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 second quarter 2013 monitoring period, no notices of violation were issued by the <br /> San Joaquin County Environmental Health Department. <br /> For the Forward Unit,environmental monitoring for the second quarter 2013 yielded results <br /> similar to previous quarters. Non-statistical exceedanccs for volatile organic compounds(VOCs) <br /> were identified at wells MW-2A and MW-10. Trend analyses indicate a statistically significant <br /> increasing temporal trend for ii propyl ether at well MW-2A,though no other statistically <br /> significant increasing temporal trends were identified for VOCs. For the inorganic monitoring <br /> parameters,concentration limits{CI s)were exceeded for constituent concentrations in wells <br /> Mitt/-2A, MW-13, MW-14,BIW-15, and background well MW-24. Statistically significant <br /> increasing temporal trends were identified for nitrate-N concentrations in well MW-14, for <br /> sulfate concentrations in well 'tvlW-15,and for sodium concentrations in background well MW- <br /> 24, Previously submitted No Release Demonstrations for these common inorganic constituents <br /> at the Forward Unit have concluded that the CL exceedances are not the result of a release from <br /> the Forward Unit. The increasing trend at background well MW-24 suggests increasing sodium <br /> concentrations upgradient of the site. <br /> Surface water samples collected from the upstream and downstream surface water monitoring <br /> st'ations during the second quarter 2013 monitoring period are generally consistent with each <br /> other, One VOC(acetone) was detected at a trace concentration in the sample from upstream <br /> surface water monitoring station FSW-2. No other VOCs were detected in second quarter 2013 <br /> surface water samples, <br />
