analyzed for general chemistry and VOCs and the results are summarized on Table 2-6. As shown in Table 2-6,two VOCs were measured in the lysimeters samples collected during the first 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 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 first quarter 2007 monitoring period surface water stations FSW-1 and FSW-2 were not sampled because both surface water stations were reported dry. 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 first quarter 2007, leachate was observed at holding areas WMU-D01,WMU-D02,WMU- FU03,WMU-FU04,WMW-FU05, and WMU-FU06. The other holding areas were reported to be dry by Forward Landfill personnel. Freeboard at WMU-F ranged from approximately 5.17 feet to 7.75 feet during the first quarter 2007 monitoring period. Appendix A presents copies of the leachate logs and the freeboard observation logs. Leachate samples were collected for the leachate pond on a monthly basis and analyzed in the field for pH and specific conductance. In addition to monthly monitoring,the leachate is sampled annually during the fourth quarter monitoring period for the parameters listed in Table 2-1. Results of monthly field monitoring measurements and analytical results for the first quarter 2007 are presented in Table 2-7. Review of the November 2006 leachate sample data indicated that of the constituents detected, sulfide and 3-&-4-Methylphenol were potential new constituents of concern (CDCs). Therefore, in accordance with WDR No. 115-2003-0049,verification samples were collected from the Forward leachate sample pond on February 5, 2007. The results from the retest indicates that both sulfide and 3-&-4-Methylphenol were confirmed in both retest samples(Table 2-7) and have been added to the COC list for the Forward Landfill. 2.2 SUMMARY Groundwater quality conditions beneath the Forward Unit during the first 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 first quarter 2007 monitoring period. Excluding suspected laboratory contaminants, estimated trace-level VOCs were measured in wells MW-10, MW-14A and MW-16; and one VOC was measured above the PQL in well MW-14A. CLs were exceeded for one or more D:12007_0043\ForwardAusBn_w07.doc 7 Geologic Associates
