Water Quality Monitoring Report <br /> Forward Landfill <br /> during the 2016 monitoring year indicates similar concentrations and no VOCs were detected <br /> suggesting that landfill operations are not impacting surface water quality. <br /> 4.4.3 Leachate Monitoring <br /> Leachate sumps are inspected for the presence of leachate and observations are recorded at <br /> least weekly by Forward Landfill personnel. If leachate is detected in a sump it is pumped into <br /> the surface impoundment (WMU-F North) for evaporation. During the 2017 monitoring year, <br /> leachate was observed at all of the holding areas except WMU D-87, WMU D-88 A/B, WMU- <br /> D89 and according to the Operations Manager, no leachate was taken off site during the 2017 <br /> monitoring year. Freeboard at WMU-F North ranged from approximately 2.1 to 13.0 feet <br /> during the 2017 monitoring year. <br /> Value Engineering conducted a continuity test of the leachate collection and removal system <br /> (LCRS) on August 11 and 12, 2017 at the Forward Unit (Appendix A). The tracer dye test results <br /> indicate that continuity is present across the LCRS units WMU-F North, and no excessive <br /> leachate is backed up in the drainage layer or sump of the LCRS units. Additionally, an annual <br /> inspection of each sump was performed by Del-Tech on June 1, 2017. The results of the <br /> inspection are included in Appendix A. <br /> 4.5 Austin Unit <br /> 4.5.1 Groundwater <br /> Groundwater elevations measured during the 2017 monitoring year generally reflect seasonal <br /> precipitation patterns. Hydrographs depicting historical groundwater elevations are presented <br /> in Appendix G and indicate generally static trends. During the 2017 monitoring year <br /> groundwater flow was generally directed to the north and northeast. <br /> Groundwater quality conditions beneath the Austin Unit during the 2017 monitoring year are <br /> generally similar to those observed in the previous monitoring year. The following table <br /> summarizes inorganic CL exceedances for DMP wells during the 2017 monitoring year. <br /> AUSTIN UNIT CL EXCEEDANCES FOR 2017 MONITORING YEAR <br /> WELL CONSTITUENT 2017 MONITORING <br /> PERIOD <br /> AMW-6 Bicarbonate,Calcium,Magnesium, Nitrate, 1Q17 <br /> Potassium,Strontium <br /> AMW-6 Bicarbonate,Calcium,Magnesium,Strontium 2Q17 <br /> AMW-7 Strontium <br /> AMW-6 Bicarbonate,Calcium,Strontium 3Q17 <br /> AMW-12 Potassium <br /> Project No.5017.1030 I Water Quality Monitoring Report 17 <br /> January 2018 <br />
