During the second quarter 2007 monitoring period no methane exceeded the regulatory limit of 5 <br /> 4p percent in perimeter soil-pore gas probes at the Forward Unit, suggesting an overall <br /> improvement in landfill gas at the site. Forward continues to install additional landfill gas <br /> extraction wells (as needed), and makes regular adjustments to the landfill gas extraction system <br /> to optimize efficiency of the landfill gas extraction system. <br /> Groundwater quality conditions beneath the Austin Unit during the second quarter 2007 <br /> monitoring period are generally similar to historical results. CLs were exceeded in DMP wells <br /> AMW-7,AMW-13, and AMW-14. However,none of the CL exceedances exhibited statistically <br /> significant increasing trends,while statistically significant decreasing VOC trends were <br /> calculated in well AMW-14. In the CAP wells,trend analyses are performed instead of <br /> comparison to CLs. During the current monitoring period,one or more statistically significant <br /> increasing trends were noted for VOC constituents in wells AMW-1,AMW-10, and AMW-19, <br /> while decreasing VOC trends were noted in CAP wells AMW-1,AMW-11,and AMW-18. The <br /> increasing cis-1,2-DCE trends in wells AMW-1 and AMW-10 suggest that active reductive <br /> dechlorination is occurring in the vicinity of these wells. <br /> According to the Forward Landfill Operations Manager,weekly standard observations have been <br /> conducted during the reporting quarter. The Forward Landfill Operations Manager also reported <br /> that no surface water was discharged during the reporting period. <br /> If you have any questions regarding this report,please call me at(858)451-1136. <br /> Sincerely, <br /> William ez, PG, CHg <br /> Project Ge ogist <br /> Attachment <br /> C:\2007-0N3\F0RWARDLT&D0C ' <br /> -2- <br /> GeoLogic Associates <br />
