2.1.7 Surface Water Monitoring Site run-on and run-off control facilities are designed to effectively channel surface water to site ston-nwater/sedimentation ponds. According to the Operations Manager,there were no discharges to surface water during the reporting quarter. During the second quarter 2011 monitoring period, surface-water monitoring stations FSW-I and FSW-2 were sampled on May 10, 2011. Table 2-7 summarizes the current analytical results of surface water samples collected at the Forward Unit. As shown on Table 2-7, one trace level VOC (acetone) was detected in the surface water sample collected from the upgradient surface water station FSW-2 during the monitoring period. A comparison of upgradient (FSW-2) to downgradient(FSW-1) surface water samples indicates generally similar inorganic constituent concentrations. Given the fact that acetone, a common laboratory contaminant, was only detected in the upgradient surface water station and the inorganic constituent concentrations are generally similar suggests that landfill operations are not impacting surface water quality. 2.2 SUMMARY Groundwater quality conditions beneath the Forward Unit during the second quarter 2011 monitoring period are generally similar to those observed in previous monitoring periods. During the second quarter 2011 monitoring period, no new historical intrawell maximum values were measured in samples collected from groundwater monitoring wells. The organic results for the Forward Unit indicate that DIPE was measured above the PQL in the sample collected from well MW-2A; DCDFM and TCFM were measured at trace concentrations in the sample collected from well MW-10; and 1,1-DCA, cis-1,2-DCE, PCE, TCE, and TCFM were measured at trace concentrations in the sample collected from well MW-14. CLs were exceeded for chloride at well MW-21; DIPE at well MW-2A; nitrate as nitrogen at well MW-19; and for sulfate at wells MW-MW-15 and MW-22. However, with the exception of the chloride concentration measured at well MW-21, the CL exceedances were for non-impact constituents or low-level VOCs that do not require retesting. 3.0 AUSTIN UNIT 3.1 WATER QUALITY MONITORING 3.1.1 Sampling and Laboratory Analyses During the second quarter 2011, depth-to-water measurements were recorded and the Austin Unit's DMP and CAP groundwater monitoring wells were sampled by Del-Tech between May 16 and June 1, 2011. Domestic wells 7898-A and 8106-A and surface water stations ASW-1 and ASW-2 were sampled on May 11, 2011. Samples were collected from each sample point with sufficient liquid and submitted to BC for analysis of the parameters stipulated in RWQCB Order No. R5-2003-0049.
