measured in the lysimeters samples collected during the second quarter 2007 monitoring period, including four VOCs above the PQL. 2.1.6 Surface Water Monitoring Site run-on and run-off control facilities are designed to effectively channel surface water to lined holding and evaporation ponds on site. According to the Operations Manager,no surface water was discharged from the facility during the reporting quarter. During the second quarter 2007 monitoring period surface water stations FSW-1 and FSW-2 were sampled on May 8, 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 second quarter 2007, leachate was observed at holding areas WMUD-93/94,WMU D-01,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 7.33 feet to 8.75 feet during the second 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 second quarter 2007 are presented in Table 2-8. 2.2 SUMMARY Groundwater quality conditions beneath the Forward Unit during the second quarter 2007 monitoring period are generally similar to those observed in previous monitoring periods. One new historical intrawell maximum value was measured for bicarbonate in sample collected from groundwater monitoring well MW-IA during the second quarter 2007 monitoring period. Excluding suspected laboratory contaminants,estimated trace-level VOCs were measured in wells MW-10 and MW-14A; and one VOC was measured above the PQL in well MW-10. CLs were exceeded for one or more monitoring parameters in samples from 12 wells. In accordance with the RPCMP, eight wells with exceedances of CLs that are potential impact constituents will be resampled in August 2007 (during the third quarter 2007 sampling event), and a second independent sample will be collected in September 2007. The results of the two retests will be submitted to DTSC and RWQCB under separate cover. Historically, similar exceedances of CLs have been measured and verified in samples collected from DMP monitoring wells at the Forward Unit, followed by no release demonstrations (NRD),which have concluded that the CL exceedances are D:\2007_0043\FomardAustin_sp07.dw 7 GeoLogic Associates
