1-1 Water Quality Monitoring Report Forward Landfill 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 3-1. As shown on Table 2-5A, samples were collected from FU -04W and pan lysimeter FU -03; all other lysimeters were reported dry. As summarized on Table 2-513, up to eight VOCs were detected (four above a PQL) in the soil -pore liquid samples the soil -pore liquid samples collected from the Austin Unit during the monitoring period. For pan lysimeter FU -03, approximately 23 gallons of liquid was pumped from the pan and discharged to surface impoundment WMU F (West). 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 third quarter 2014, leachate was observed at holding areas WMU FU -03, WMU FU -04, WMU FU -05, WMU FU -06, WMU FU -10, WMU FU -13, and WMU FU -14 and a total of 87,500 gallons of leachate was removed from the lined areas at an average rate of 957 gallons per day. For surface impoundment WMU-F (West) Freeboard ranged from approximately 4.50 to 5.58 feet during the third 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 third 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 third quarter 2014 monitoring period. 3.1.11 Corrective Action Monitoring The Groundwater Treatment Facility (GTF) at the Austin Unit has been operational since 1994 to mitigate impacts from landfill releases. Impacted groundwater is extracted from four wells (EW -1, EW -2, EW -311, and EW -4) that pump groundwater through an air M:\ 2014.0012\FA_3Q14.docx 12 10/31/2014, Rev. 0
