organic results for the Forward Unit indicate that acetone and trans-l,4-dichloro-2-butene were measured above the PQL in the samples collected from wells MW-19 and DW-9690, respectively. In addition, PCE, and TCE were detected at estimated trace concentrations in the sample collected from well MW-14. CLs were exceeded for one or more monitoring parameters in samples from seven wells. In accordance with the RPCMP, inorganic exceedances of CLs that are potential impact constituents will be resampled in November 2010 (during the fourth quarter 2010 sampling event), and a second independent sample will be collected in December 2010. The results of the two retests will be submitted to DTSC and RWQCB under separate cover. During the July, August, and September 2010 inspections, the CEHD measured methane concentrations exceeding the regulatory limit of five percent in perimeter soil-pore gas probe GP-11. In response to elevated methane concentrations measured in this probe, Forward has prepared a landfill gas remediation plan which has been submitted to the CEHD and Cal Recycle. 3.0 AUSTIN UNIT 3.1 WATER QUALITY MONITORING 3.1.1 Sampling and Laboratory Analyses During the third quarter 2010, depth-to-water measurements were recorded and the Austin Unit's DMP and CAP groundwater monitoring wells were sampled by Del-Tech between August 19 and 23, 2010. Surface water stations were inspected and samples were collected from surface water station ASW-1 on August 20, 2010, while station ASW-2 was reported dry. Samples were collected from each sample point with sufficient liquid and submitted to TestAmerica for analysis of the parameters stipulated in RWQCB Order No. 85-2003- 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 dissolved oxygen, turbidity, temperature, specific conductance, and pH and recorded on well data sheets. The groundwater monitoring wells and leachate were sampled in accordance with the sampling and analysis procedures detailed in Appendix B. The well data sheets, raw laboratory data, certificates of analyses, and chain-of-custody records related to the sampling program are included in Appendix C. Field and laboratory analyses are summarized in Tables 3-1 through 3-6. 3.1.2QA/QC Results The QA/QC program completed for the third quarter 2010 water quality monitoring event at the Austin Unit included analyses of one field blank, one trip blank, and four laboratory method blanks. The trip, field, and equipment blanks were analyzed for VOCs by EPA Method 8260 and method blanks were analyzed for all required analyses. The D:\2010_0013\FA_3Q Mdoc 8
