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, 2016 (first quarter 2016). 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 2016 monitoring period, a notice of violation (NOVs) was issued by the San Joaquin County Environmental Health Department on March 18, 2016 for exposed waste at the previous day active face, no other NOVs were issued during the monitoring period. For the Forward Unit, environmental monitoring for the first quarter 2016 yielded results similar to previous quarters. A non -statistical indication of release was identified at wells MW - 13 and MW -16 as a result of one volatile organic compound (VOC) measured at a quantifiable concentration and at wells MW -14 and MW -17 as a result of three VOCs measured at estimated -trace concentrations in each well. For the inorganic monitoring parameters, one or more concentration limits (CLs) were exceeded at wells MW -2A, MW -10, MW -13, MW -18, and MW -22. Verification sampling for the organic and inorganic CL exceedances is scheduled for April 2016. Surface water samples collected from the upstream and downstream surface water monitoring stations during the first quarter 2016 monitoring period are generally consistent with each other; no VOCs were detected and no CLs were exceeded. Vadose zone monitoring stations were reported dry or had an insufficient volume of soil -pore liquid to sample. Groundwater quality conditions beneath the Austin Unit during the first quarter 2016 monitoring period were generally similar to historical results. With the exception of well AMW- 6, only one CL was exceeded for DMP wells during the current monitoring period. Verification sampling for the CL exceedance at well AMW-5R is scheduled for April 2016. Although, several CLs were exceeded and several VOCs were detected in well AMW-6, and it is recognized that well AMW-6 should have been identified a Corrective Action Program (CAP)well in the M&RP. 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 seven measured above a PQL. Surface water samples collected from the upstream and downstream surface water monitoring stations during the first quarter 2016 monitoring period are generally consistent with each other and no VOCs were detected and no CLs were exceeded. All of the lysimeters were reported dry or there was an insufficient volume of soil -pore liquid for analysis during the first quarter 2016 monitoring period. Under the existing CAP, the groundwater treatment facility (GTF) pumped 22.5 million gallons of groundwater removing an estimated 1.58 pounds of VOCs. 0 M:\ 2016.0007\ExecSum 1Q16.docx E-1
