WMU D-88 A/B. Freeboard at WMU-F ranged from approximately 4.75 to 9.92 feet during the first quarter 2012 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, specific conductance, and temperature. Results of monthly field monitoring measurements for the first quarter 2012 are presented in Table 2-6. 2.1.7 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. On February 2, 2012, Del-Tech reported that both surface-water monitoring stations FSW-1 and FSW-2 were dry. 2.2 SUMMARY Groundwater quality conditions beneath the Forward Unit during the first quarter 2012 monitoring period are generally similar to those observed in previous monitoring periods. During the first quarter 2012 monitoring period, DIPE was measured above its PQL in the samples collected from wells MW-2A and M -16. In addition, one or more VOCs were measured at estimated trace concentrations in the samples collected from wells MW-14 and MW-18. CLs were exceeded for constituent concentrations in wells MW-2A, MW-15, MW-16, MW-18, and MW-24. Excluding non-impact constituents and low-level VOCs, confirmation sampling for strontium in well MW-18 will be performed in May 2012 during the second quarter 2012 monitoring event, and in June 2012. The results of the confirmation sampling will be provided under separate cover. 3.0 AUSTIN UNIT 3.1 WATER QUALITY MONITORING 3.1.1 Sampling and Laboratory Analyses During the first quarter 2012, depth-to-water measurements were recorded and the Austin Unit's DMP and CAP groundwater monitoring wells were sampled by Del-Tech on February 22 and 24, 2012. Surface water stations ASW-1 and ASW-2 were reported dry during the sampling event. 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. Table 2-1 presents the monitoring schedule and summarizes the analytical methods utilized during the current monitoring period. Water quality samples were also analyzed in the field for ORP,turbidity, temperature, specific conductance, and pH and recorded on well data sheets. The groundwater monitoring wells and leachate were sampled in accordance C:\2012-0025\FA_1Q12.doc 7 Geo-Logic Associates
