collection. However,due to the limited sample volumes, lysimeter samples were only 0 analyzed for select general chemistry constituents and/or VOCs. As shown in Table 2-6, two VOCs were measured above the PQL in the lysimeter samples collected during the third quarter 2007 monitoring period. 2.1.6 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,no surface water was discharged from the facility during the reporting quarter. During the third quarter 2007 monitoring period surface water stations FSW-1 and FSW-2 were sampled on August 15, 2007. Table 2-7 summarizes the analytical results for surface water samples collected at the Forward Unit. A comparison of upgradient (FSW-2)to downgradient(FSW-1) surface water samples indicates generally similar concentrations suggesting that the landfill operations are not impacting surface water quality. 2.1.7 Leachate Monitoring Leachate sumps are inspected for the presence of leachate and observations are recorded at least weekly by Forward Landfill personnel. If leachate is detected in a sump, it is pumped into the surface impoundment(WMU F) for evaporation. During the third quarter 2007, leachate was observed at holding areas WMUD-93/94, WMU D-02, WMU FU-03,WMU FU-04,WMW FU-05, and WMU FU-06. The other holding areas were reported to be dry by Forward Landfill personnel. Freeboard at WMU-F ranged from approximately 8.50 feet to 9.25 feet during the third quarter 2007 monitoring period. Appendix A presents copies of the leachate logs and the freeboard observation logs. Leachate samples were collected on a monthly basis and analyzed in the field for pH and specific conductance. The results of monthly field monitoring measurements for the third quarter 2007 are presented in Table 2-8. Value Engineering conducted a gas test of the leachate collection and removal system (LCRS)on August 23,2007 at the Forward Unit. The test results indicate that an open- air conduit is present across the LCRS units, and no excessive leachate is backed up in the drainage layer or sump of the LCRS units. A summary of the test results is provided in Appendix A. 2.2 SUMMARY Groundwater quality conditions beneath the Forward Unit during the third quarter 2007 monitoring period are generally similar to those observed in previous monitoring periods. Eight new historical intrawell maximum values were measured in samples collected from groundwater monitoring wells during the third quarter 2007 monitoring period. Excluding suspected laboratory/field contaminants, estimated trace-level VOCs were measured in wells MW-10,MW-14, MW-16, and MW-21; and one VOC was measured D:\2007 0043\ForwardAusdn sum07.doc - - 7 Geologic Associates
