Water Quality Monitoring Report Forward Landfill EXECUTIVE SUMMARY 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 (RWQCB) Waste Discharge Requirements (WDRs) Order Number 115-2014-0006. This report presents quarterly sampling results for the reporting period dating from July 1 to September 30, 2014 (third quarter 2014). 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 third quarter 2014 monitoring period, no notices of violation were issued by the San Joaquin County Environmental Health Department or RWQCB. For the Forward Unit, environmental monitoring for the third quarter 2014 yielded results similar to previous quarters. During the third quarter 2014 monitoring period, a non-statistical indication of release was identified at well MW-2A as a result of one volatile organic compound (VOC) measured at a quantifiable concentration and at well MW-17 as a result of two VOCs measured at estimated-trace concentrations. No other VOCs were detected in groundwater samples during the third quarter 2014 monitoring period. For the inorganic monitoring parameters, one or more concentration limits (CLs) were exceeded at wells MW-1, MW-2A, MW-10, MW-13, MW-15, MW-17, MW-19, and MW-24. Verification sampling for the organic and inorganic CL exceedances is scheduled for October 2014. During the monitoring period surface water sampling locations were reported dry. For vadose zone monitoring up to 14 VOCs were detected in soil-pore liquid samples and approximately 9600 gallons of liquid was pumped from pan lysimeter WMU-D01N. Groundwater quality conditions beneath the Austin Unit during the third quarter 2014 monitoring period were generally similar to historical results. During the current monitoring period, a non-statistical indication of release was identified at well AMW-6 as a result of three VOCs (two quantifiable and one estimated-trace concentrations). No other VOCs were detected in DMP wells. For inorganic monitoring parameters, one CL was exceeded at wells AMW-6 and AMW-7. Verification sampling for the inorganic CL exceedance is scheduled for October 2014. For the Corrective Action Program (CAP)/Evaluation Monitoring wells, 16 wells reported one or more VOCs exceeding a practical quantitation limit (PQL), with CAP well AMW- 1 having the greatest number of VOCs (nine), including seven measured above a PQL. During the monitoring period surface water sampling locations were reported dry. For vadose zone monitoring up to six VOCs were detected in soil-pore liquid samples and approximately 23 gallons of liquid was pumped from pan lysimeter FU-03. To mitigate impacts at the Austin Unit, the groundwater treatment facility (GTF) pumped nearly 20 million gallons of groundwater from the extraction wells resulting in the removal of 0.49 pounds of VOCs.
