Water Quality Monitoring Report
<br /> Forward Landfill
<br /> ® 3.2 Summary
<br /> Groundwater quality conditions beneath the Austin Unit during the second quarter 2015
<br /> monitoring period were generally similar to historical results. During the current
<br /> monitoring period, although it is recognized that well AMW-6 is a CAP well mis-
<br /> identified as a DMP well, six inorganic CLs were exceeded and a non-statistical indication
<br /> of release was identified at well AMW-6. In addition, the CL for sodium was exceeded in
<br /> well AMW-7 and verification retesting is scheduled for July 2015. With the exception of
<br /> AMW-6, no other VOCs were detected in DMP wells. For the CAP/evaluation wells, 17
<br /> of 28 wells reported one or more VOCs exceeding a PQL, with CAP well AMW-1 having
<br /> the greatest number of VOCs (14), including 10 measured above a PQL. All surface
<br /> water stations and lysimeters were reported dry during the second quarter 2015
<br /> monitoring period. Under the existing CAP, the GTF pumped 11.0 million gallons of
<br /> groundwater removing an estimated 0.89 pounds of VOCs.
