During the third quarter 2008 monitoring period, methane concentrations did not exceed the regulatory limit of five percent in perimeter soil-pore gas probes at the Forward Unit. Forward continues to install additional landfill gas extraction wells (as needed), and makes regular adjustments to the landfill gas extraction system to optimize efficiency of the landfill gas extraction system. The retest results for the 5-year COC sampling conducted during the second quarter 2008 monitoring period indicates that none of the COCs were confirmed in the retest samples, suggesting that the primary results were false positives, and no changes to the list of monitoring parameters is warranted. 3.0 AUSTIN UNIT 3.1 WATER QUALITY MONITORING 3.1.1 Sampling and Laboratory Analyses During the third quarter 2008, depth-to-water measurements were recorded in the groundwater monitoring wells on August 11, 2008 and the Austin Unit's DMP and CAP groundwater monitoring wells were sampled by ATC between August 11 and 13, 2008. Both surface water stations were sampled on August 11,2008. A single sample set was 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 dissolved oxygen, turbidity, temperature, specific conductance, and pH and recorded on well data sheets. The groundwater monitoring wells, surface water monitoring points, 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. The results of both field and laboratory analyses are summarized in Tables 3-1 through 3-6. 3.1.2 QA/QC Results The QA/QC program completed for the third quarter 2008 water quality monitoring event at the Austin Unit included analyses of three field blanks,three trip blanks,three laboratory method blanks, and one duplicate sample. The trip, field, and laboratory method blanks were analyzed for VOCs by EPA Method 8260 and are included with the laboratory data in Appendix C. Laboratory method blanks were analyzed for all of the analytes included in the monitoring program. The results of the QA/QC program indicate that acetone,bromoform, dibromochloromethane, and methylene chloride were detected in one or more of the QA/QC blanks during the monitoring period. Review of the primary sample results indicates that a similar concentration of bromoform, D:\2M 0010\FA_3Q0&dce 9 Geologic Associates
