parameters listed in Table 2-1. Results of monthly field monitoring measurements and analytical results for the fourth quarter 2013 are presented in Table 2-6. As shown in Table 2-6,two VOCs, 14 dissolved metals, and numerous inorganic constituents were detected in the fourth quarter leachate sample. No semi-volatile organic compounds (SVOCs),herbicides, or pesticides were detected. Review of the annual 2013 leachate sample data indicates no new COCs were detected above PQLs, and therefore, no verification retesting is required. 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 during the reporting quarter. Surface water monitoring stations FSW-1 (downstream)and FSW-2 (upstream)were reported dry on November 7, 2013 during the fourth quarter 2013 monitoring period. As a result, no samples were collected. 2.2 SUMMARY Groundwater quality conditions beneath the Forward Unit during the fourth quarter 2013 monitoring period are generally similar to those observed in previous monitoring periods. During the fourth quarter 2013 monitoring period, only one VOC (DCDFM)was measured at a trace concentration in the sample collected from well MW-10. For the ® inorganic monitoring parameters, CLs were exceeded for constituent concentrations in wells MW-2A,MW-13,MW-14, MW-15 and background well MW-23R. Statistically significant increasing temporal trends were identified for chloride concentrations in well MW-2A, nitrate-N concentrations in well MW-14, and sulfate concentrations in well MW-15. However,review of groundwater flow directions suggests that the increasing trends for inorganic constituents may be related to changing conditions in background associated with agricultural activities. Surface water sampling locations were dry during the fourth quarter 2013 monitoring period. 3.0 AUSTIN UNIT 3.1 WATER QUALITY MONITORING Sampling and Laboratory Analyses Fourth quarter 2013 monitoring included monitoring of routine monitoring locations as well as offsite EMP wells. Depth-to-water measurements were recorded in the groundwater monitoring wells on November 8, 2013. Groundwater, surface water, and leachate sampling was performed on November 18 through 20, 2013 for routine monitoring locations and on December 5 and 6, 2013 for the offsite EMP wells.
