AMW-11. The increasing trend exhibited for cis-1,2-DCE at wells AMW-1 and <br /> AMW-10, suggests reductive dechlorination is occurring in the vicinity of these wells. <br /> 3.1.6 Domestic Well Monitoring <br /> Two domestic wells (7898-A and 8106-A) were sampled on August 23, 2010. Table 3-3 <br /> summarizes the current analytical results for the domestic well samples collected. In the <br /> sample collected from well 7898-A, PCE was measured at a trace concentration. In the <br /> sample collected from well 8106-A, DCDFM, PCE, and TCE were measured above their <br /> respective PQLs. <br /> 3.1.7 Surface Water Monitoring <br /> Surface-water sampling was conducted on August 20, 2010 and the results are <br /> summarized on Table 3-5. During the third quarter 2010 monitoring event, only surface <br /> water monitoring station ASW-1 had sufficient water to collect a sample, while surface- <br /> water monitoring station ASW-2 was reported dry. <br /> 3.1.8 Leachate Monitoring <br /> According to the Operations Manager, no leachate was taken off site during the third <br /> quarter 2010. The leachate collection system, which collects leachate from the north face <br /> of the landfill, has been operational since November 1996. WQPS (concentration limits) <br /> are not required for leachate because it is collected and removed for disposal,rather than <br /> discharged. According to the Operations Manager, the LCRS operated effectively during <br /> the third quarter 2010. <br /> Leachate samples were collected from the pond on a monthly basis and analyzed in the <br /> field for pH, specific conductance, and temperature. The results of monthly field <br /> monitoring measurements are presented in Table 3-6. <br /> 3.1.9 Groundwater Treatment Facility Operations <br /> The Groundwater Treatment Facility(GTF) at the Austin Unit has been operational since <br /> 1994 to mitigate impacts from landfill releases. Currently, impacted groundwater is <br /> extracted from four wells (EW-1, EW-2, EW-3R, and EW-4), treated, and discharged to <br /> an infiltration pond. During the monitoring period, the GTF treated 15,605,400 gallons <br /> of groundwater at an average flow rate of 106 gallons per minute, or 153,205 gallons per <br /> day. During the monitoring period, the GTF removed approximately 5.57 pounds of <br /> VOCs. <br /> W20 1000 t 31 EA_3Q t Moe <br /> 12 <br />
