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 January 1 to March 31, 2015 (first quarter 2015). 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 2015 monitoring period, no notices of violation (NOVs) were issued by the San Joaquin County Environmental Health Department. The RWQCB issued a NOV on February 19, 2015 for failure to submit the Cannery Waste Water Quality Protection Standards Report. However, based on facility documentation of insufficient data to support development of WQPS, Forward has requested that this NOC be rescinded. For the Forward Unit, environmental monitoring for the first quarter 2015 yielded results similar to previous quarters. A non-statistical indication of release was identified at well MW- 13 as a result of one volatile organic compound (VOC) measured at a quantifiable concentration and at well MW-14 as a result of three VOCs measured at estimated-trace concentrations. For the inorganic monitoring parameters, one or more concentration limits (CLs) were exceeded at wells MW-2A and MW-18. Verification sampling for the organic and inorganic CL exceedances is scheduled for April 2015. Surface water samples collected from the upstream and downstream surface water monitoring stations during the first quarter 2015 monitoring period are generally consistent with each other; no VOCs were detected and no CLs were exceeded. Of the vadose zone monitoring points, 10 VOCs were detected in soil-pore liquid samples and approximately 2,300 gallons of liquid was pumped from pan lysimeter WMU-D01N. Groundwater quality conditions beneath the Austin Unit during the first quarter 2015 monitoring period were generally similar to historical results. During the current monitoring period, although it is recognized that well AMW-6 is a CAP well misidentified as a DMP well, three inorganic CLs were exceeded and a non-statistical indication of release was identified at well AMW-6. No other VOCs were detected in DMP wells. For the Corrective Action Program (CAP)/Evaluation Monitoring wells, 17 wells reported one or more VOCs exceeding a practical quantitation limit (PQL), with CAP well AMW-1 having the greatest number of VOCs (14), including eight measured above a PQL. Surface water samples collected from the upstream and downstream surface water monitoring stations during the first quarter 2015 monitoring period are generally consistent with each other and no VOCs were detected. With the exception of FU-04W, all of the lysimeters were reported dry. However, there was insufficient soil-pore liquid from FU-04W for analysis. To mitigate impacts at the Austin Unit, the groundwater treatment facility (GTF) pumped nearly 22.7 million gallons of groundwater from the extraction wells resulting in the removal of 1.13 pounds of VOCs.
