Water Quality Monitoring Report <br /> Forward Landfill <br /> 3.1.7 Domestic Well Monitoring <br /> Two domestic wells (7898-A and 8106-A) were sampled on September 3, 2015. Table 3- <br /> 5 summarizes the current analytical results for the domestic well samples collected. As <br /> shown on Table 3-5, a quantified concentration of PCE was measured in well 7898-A; <br /> and quantified concentrations of PCE, TCE, and DCDFM were measured in well 8106-A. <br /> In addition, trace concentrations of cis-1,2-dichloroethene and 1,1-dichloroethane were <br /> measured in well 8106-A; and trace concentrations of DCDFM and TCE were measured <br /> in well 7898-A. <br /> 3.1.8 Vadose Zone Monitoring <br /> The current vadose-zone monitoring network at the Austin Unit consists of seven <br /> lysimeters. The lysimeter locations are shown on Figure 3-1. As shown on Table 2-5A, <br /> all lysimeters were reported dry or there was an insufficient volume of soil-pore liquid (4 <br /> milliliters)for analysis during the monitoring period. <br /> 3.1.9 Leachate/Surface Impoundment Monitoring <br /> Leachate sumps and surface impoundments are inspected weekly by Forward Landfill <br /> personnel. If leachate is detected in a sump, it is pumped into the surface <br /> impoundment WMU F (West) for evaporation. During the third quarter 2015, leachate <br /> was observed at holding areas WMU FU-03, WMU FU-04, WMU FU-05, WMU FU-06, <br /> WMU FU-13, and WMU FU-14 and a total of 288,000 gallons of leachate was removed <br /> from the lined areas at an average rate of 3,130 gallons per day. For surface <br /> impoundment WMU-F (West) freeboard ranged from approximately 6.33 to 6.92 feet <br /> during the third quarter 2015 monitoring period. Appendix A presents copies of the <br /> leachate observation logs, freeboard observation logs, and surface impoundment <br /> monitoring log. <br /> Leachate samples were collected on a quarterly basis and analyzed in the field for pH, <br /> specific conductance, temperature, and turbidity. The results of quarterly field <br /> monitoring measurements for the third quarter 2015 are presented in Table 3-7. <br /> 3.1.10 Surface Water Monitoring <br /> Site run-on and run-off control facilities are designed to effectively channel surface <br /> water to site stormwater/sedimentation ponds. According to the Operations Manager, <br /> there were no discharges to surface water during the reporting period. On September <br /> 1, 2015, surface water monitoring stations ASW-1 (upstream) and ASW-2 (downstream) <br /> were reported dry. <br /> M:\2015.0014\FA 3Q15.docx 12 <br />
