2.1.7 Surface Water Monitoring <br /> Site run-on and run-off control facilities are designed to effectively channel surface water <br /> to site stormwater/sedimentation ponds. According to the Operations Manager, there <br /> were no discharges to surface water during the reporting quarter. On April 24, 2012, Del- <br /> Tech reported that both surface-water monitoring stations FSW-1 and FSW-2 were dry. <br /> 2.2 SUMMARY <br /> Groundwater quality conditions beneath the Forward Unit during the second quarter 2012 <br /> monitoring period are generally similar to those observed in previous monitoring periods. <br /> During the second quarter 2012 monitoring period, DIPE was measured above its PQL in <br /> the samples collected from wells MW-2A and MW-16. In addition, PCE and TCE were <br /> measured at estimated trace concentrations in the sample collected from well MW-14. <br /> CLs were exceeded for constituent concentrations in wells MW-2A, MW-13, MW-14, <br /> MW-15, and MW-16. Excluding non-impact constituents and low-level VOCs, <br /> confirmation sampling for chloride in well MW-13 and barium in well MW-14 will be <br /> performed in August 2012 during the third quarter 2012 monitoring event, and in <br /> September 2012. The results of the confirmation sampling will be provided under <br /> separate cover. <br /> 3.0 AUSTIN UNIT <br /> 3.1 WATER QUALITY MONITORING <br /> 3.1.1 Sampling and Laboratory Analyses <br /> During the second quarter 2012, depth-to-water measurements were recorded and the <br /> Austin Unit's DMP and CAP groundwater monitoring wells were sampled by Del-Tech <br /> on May 3 and 4, 2012. Surface water stations ASW-1 and ASW-2 were sampled on May <br /> 4, 2012. <br /> Samples were collected from each sample point with sufficient liquid and submitted to <br /> BC for analysis of the parameters stipulated in RWQCB Order No. R5-2003-0049. Table <br /> 2-1 presents the monitoring schedule and summarizes the analytical methods utilized <br /> during the current monitoring period. Water quality samples were also analyzed in the <br /> field for ORP, turbidity, temperature, specific conductance, and pH and recorded on well <br /> data sheets. The groundwater monitoring wells and leachate were sampled in accordance <br /> with the sampling and analysis procedures detailed in Appendix B. The well data sheets, <br /> raw laboratory data, certificates of analyses, and chain-of-custody records related to the <br /> sampling program are included in Appendix C. Field and laboratory analyses are <br /> summarized in Tables 3-1 through 3-6. <br /> C:\2012-0025TA_2Q 12.doc 7 Geo-Logic Associates <br />
