Water Quality Monitoring Report Forward Landfill 3.1.7 Domestic Well Monitoring Two domestic wells (7898-A and 8106-A) were sampled on April 17, 2014. Table 3-5 summarizes the current analytical results for the domestic well samples collected. Tetrachloroethene was measured above the PQL in both domestic well samples and cis- 1,2-dichloroethene, dichlorodifluoromethane, and trichloroethene was also measured above PQLs in the sample collected from well 8106-A. An estimated trace concentration of one VOC was also measured in the sample from each domestic well 3.1.8 Vadose Zone Monitoring The current vadose-zone monitoring network at the Austin Unit consists of seven lysimeters. The lysimeter locations are shown on Figure 2-1. As recorded in the field notes for lysimeters (Appendix F) and summarized on Table 2-5A, all Austin Unit lysimeters were reported dry, and as a result, no soil-pore liquid samples were collected during the current monitoring period. 3.1.9 Leachate/Surface Impoundment Monitoring; For the Austin 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 (West) for evaporation. During the second quarter 2014, leachate was observed at holding areas WMU FU-03, WMU FU-04, WMU FU-05, WMU FU-06, WMU FU-10, and WMU FU-13 and a total of 89,080 gallons of leachate was removed from the lined areas at an average rate of 979 gallons per day. For surface impoundment WMU-F (West) Freeboard ranged from approximately 2.32 to 2.70 feet during the second quarter 2014 monitoring period. Appendix A presents copies of the leachate observation logs, freeboard observation logs, and dissolved oxygen measurements. Leachate samples were collected on a quarterly basis and analyzed in the field for pH, specific conductance, temperature, and turbidity. The results of quarterly field monitoring measurements for the second quarter 2014 are presented in Table 3-7. 3.1.10 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 to surface water (waters of the United States) during the reporting period. Surface water monitoring stations ASW-1 (upstream) and ASW-2 (downstream) were reported dry during the second quarter 2014 monitoring period. M:\2014.0012\FA_2Q14rev.docx 12 9/5/2014,Rev.1
