Water Quality Monitoring Report Forward Landfill is 2.1.6 Leachate/Surface Impoundment Monitoring For the Forward Unit, leachate sumps and surface impoundments are inspected weekly by Forward Landfill personnel. If leachate is detected in a sump, it is pumped into the surface impoundment WMU F (North) for evaporation. During the fourth quarter 2015, leachate was observed at holding areas WMU D-93/94, WMU D-01N/S, and WMU D-02 and a total of 86,600 gallons of leachate was removed from the lined areas at an average rate of 941 gallons per day. For surface impoundment WMU-F (North), freeboard ranged from approximately 9.92 to 10.92 feet during the fourth quarter 2015 monitoring period. Appendix A presents copies of the leachate observation logs, freeboard observation logs, and dissolved oxygen measurements. Leachate samples from Forward Unit and Compost Area retention basins are analyzed in the field for pH, specific conductance, temperature, and turbidity on a quarterly basis. Results of quarterly field monitoring measurements for the fourth quarter 2015 are presented in Table 2-7. In addition to quarterly monitoring, leachate is sampled annually during the fourth quarter monitoring period for the parameters listed in Table 2-1. Results of quarterly field monitoring and analytical results for the fourth quarter 2015 are presented in Table 2-7. As shown in Table 2-7, eight VOCs were detected in the WMU F (North) leachate sample. Of note, the annual compost pond sample will be collected during the first quarter 2016 sampling event. 2.1.7 Surface Water Monitoring Site run-on and run-off control facilities are designed to effectively channel surface water to site stormwater/sedimentation ponds. According to the Operations Manager, there were no discharges from the Forward Unit to surface water (waters of the United States) during the reporting period. Surface water monitoring stations FSW-1 (downstream) and FSW-2 (upstream) were reported dry on November 18, 2015. It should be noted that flows are controlled upstream of the landfill. 2.2 Summary Groundwater quality conditions beneath the Forward Unit during the fourth quarter 2015 monitoring period are generally similar to those observed in previous monitoring periods. A non -statistical indication of release was identified at wells MW -16 as a result of one VOC measured at a quantifiable concentration; and at well MW -17 as a result of two VOCs measured at a quantifiable concentrations. However, all of the VOCs are well below MCLS. Of note, these organic constituents have been previously confirmed and are currently in "Tracking Mode". For the inorganic monitoring parameters, CLs were exceeded at wells MW -10, MW -18, and MW -24. Verification sampling for the inorganic CL exceedances is scheduled for February 2016. For constituent concentrations in "Tracking Mode" an increasing trend was calculated for chloroform at well MW -17. In response, Forward is in the process of bringing online several inactive LFG extraction wells M:\ 2015.0014\FA_4Q15.docx 9 1/29/2016, Rev. 0
