Landfill. In an effort to reduce the number of false positive results, GLA has submitted a request <br /> to the DTSC, on behalf of Forward,to update the CLs for the Forward Unit. <br /> During the second quarter 2009 monitoring period,methane concentrations did not exceed the <br /> regulatory limit of five percent in perimeter soil-pore gas probes at the Forward Unit. Forward <br /> continues to install additional landfill gas extraction wells(as needed), and makes regular <br /> adjustments to the landfill gas extraction system to optimize efficiency of the landfill gas <br /> extraction system. <br /> Groundwater quality conditions beneath the Austin Unit during the first quarter 2009 monitoring <br /> period are generally similar to historical results. CLs were exceeded in DMP wells AMW-6, <br /> AMW-7,AMW-13, and AMW-14, however, none of the CL exceedances exhibited statistically <br /> significant increasing trends. 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 Corrective Action Program (CAP)wells <br /> AMW-1,AMW-10, and AMW-19, while decreasing VOC trends were noted in CAP wells <br /> AMW-4,AMW-5/5R,AMW-10, and AMW-11. The increasing cis-1,2-DCE trends in wells <br /> AMW-1 and AMW-10 suggest that active reductive dechlorination is occurring in the vicinity of <br /> 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 /> I certify under penalty of law,that I have personally examined and am familiar with the <br /> information submitted in this document and all attachments, and that based on my inquiry of <br /> those individuals immediately responsible for obtaining this information, I believe that the <br /> information is true, accurate, and complete.
