Water Quality Monitoring Report <br /> Forward Landfill <br /> is <br /> groundwater monitoring wells downgradient of the Austin Unit as part of an on-going <br /> EMP investigation. <br /> 4.5.2 Surface Water <br /> Site run-on and run-off control facilities are designed to effectively channel surface <br /> water to lined holding and evaporation ponds on site. According to the Operations <br /> Manager, no surface water was discharged from the facility during the 2014 monitoring <br /> year. With the exception of the fourth quarter 2014, the surface water surface water <br /> stations were reported dry. Comparisons of the water quality data from upgradient <br /> (ASW-1) to downgradient (ASW-2) surface water stations during the 2014 monitoring <br /> year indicates similar concentrations and no VOCs were detected suggesting that landfill <br /> operations are not impacting surface water quality. <br /> 4.5.3 Leachate Monitoring <br /> Leachate sumps are inspected for the presence of leachate and observations are <br /> recorded at least weekly by Forward Landfill personnel. If leachate is detected in a <br /> sump it is pumped into the surface impoundment (WMU-F West) for evaporation. <br /> During the 2014 monitoring year, leachate was observed at all of the holding areas and <br /> according to the Operations Manager, no leachate was taken off site during the 2014 <br /> monitoring year. Freeboard at WMU-F West ranged from approximately 2.32 to 8.42 <br /> feet during the 2014 monitoring year. <br /> Value Engineering conducted a continuity test of the leachate collection and removal <br /> system (LCRS) on August 22 and 23, 2014 at the Austin Unit. The tracer dye test results <br /> indicate that continuity is present across the LCRS unit WMU-F West, and no excessive <br /> leachate is backed up in the drainage layer or sump of the LCRS unit. <br /> • <br /> M:\2014.0012\FA_4Q14.docx 18 <br /> 1/28/2015,Rev.0 <br />
