FORWARD LANDFILL 9999 S.Austin Road ® Manteca,CA 95336 (209)982-4298,Fax(209)982-1009 April 29, 2013 JN: 2013-0021 Mr. Ross Atkinson Central Valley Regional Water Quality Control Board 11020 Sun Center Drive, Suite 200 Rancho Cordova, CA 95670-6114 SUBJECT: FIRST QUARTER 2013 WATER QUALITY MONITORING REPORT FORWARD LANDFILL SAN JOAQUIN COUNTY, CALIFORNIA Forward Incorporated (Forward)is pleased to submit the subject water quality monitoring report for the Forward Landfill in compliance with reporting requirements of the Regional Water Quality Control Board- Central Valley Region (RQCB)Waste Discharge Requirements (WDRs)Order Number R5-2003-0049. This report presents quarterly sampling results for the reporting period dating from January 1 to March 31, 2013 (first quarter 2013). In addition, the analytical results for the five-year constituents of concern(COC)monitoring event are also included in this report. According to the Forward Landfill Operations Manager, standard observations have been conducted weekly during the reporting quarter. The Forward Landfill Operations Manager also reported that no surface water was discharged from the facility during the reporting period. During the first quarter 2013 monitoring period, no notices of violation were issued by the San Joaquin County Environmental Health Department. For the Forward Unit,environmental monitoring for the first quarter 2013 yielded results similar to previous quarters. Non-statistical exceedances for volatile organic compounds (VOCs) were identified at well MW-2A and MW-10. However,trend analyses indicate that there were no statistically significant increasing temporal trends calculated for the VOCs detected in wells MW-2A and MW-10. For the routine inorganic monitoring parameters, concentration limits (CLs) were exceeded for constituent concentrations in wells MW-2A, MW-13, MW-14, MW-15, and MW-23R. With the exception of nitrate-N concentrations in well MW-14 and sulfate concentrations in well MW-15,trend analyses indicate that there were no statistically significant increasing trends calculated for the CL exceedances during the current monitoring period. Previously submitted No Release Demonstrations for these common inorganic constituents at the Forward Unit have concluded that the CL exceedances are not the result of a release from the Forward Unit. Surface water samples collected from the upstream and downstream surface water monitoring stations during the first quarter 2013 monitoring period are generally consistent with each other and no VOCs were detected. These results suggest that landfill operations are not impacting surface water.
