exceedances are likely the result of naturally occurring conditions and therefore not indicative of <br /> ® a release from the Forward Landfill. While low-level VOCs have been attributed to landfill gas <br /> migration. <br /> Groundwater quality conditions beneath the Austin Unit during the third quarter 2006 monitoring <br /> period are generally similar to historical results. Excluding confirmed laboratory contaminants, <br /> CLs were exceeded in DMP wells AMW-7,AMW-13, and AMW-14. In addition, statistically <br /> significant increasing VOC concentrations were calculated in well AMW-13, while statistically <br /> significant decreasing VOC trends were calculated in well AMW-14. In the corrective action <br /> program(CAP)wells, trend analyses are performed instead of comparison to CLs. During the <br /> current monitoring period, statistically significant increasing trends were noted for VOCs in <br /> wells AMW-1 and AMW-10,while several decreasing VOC trends were noted for CAP well <br /> AMW-11. As summarized in the Annual Corrective Action Evaluation prepared by Herst& <br /> Associates (2006),the overall groundwater quality at the Austin Road Unit is improving. <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 B.
