n <br />Water Quality Monitoring Report <br />Forward Landfill <br />stripper treatment system to remove VOCs. Treated groundwater is discharged to an <br />infiltration pond (constructed in 2003) north of the Austin Road Unit of the Forward <br />Landfill. During the monitoring period, Herst and Associates (2014) calculated that the <br />GTF treated 19.7 million gallons of groundwater and removed approximately 0.49 <br />pounds of VOCs. Details regarding corrective action remediation system operations and <br />performance evaluation for the third quarter 2014 are presented in Appendix C. <br />3.2 Summary <br />Groundwater quality conditions beneath the Austin Unit during the third quarter 2014 <br />monitoring period were generally similar to historical results. During the current <br />monitoring period, a non -statistical indication of release was identified at well AMW-6 <br />as a result of three VOCs (two quantifiable and one estimated -trace concentrations). No <br />other VOCs were detected in DMP wells. For inorganic monitoring parameters, one CL <br />were exceeded at wells AMW-6 and AMW-7. Verification sampling for the inorganic CL <br />exceedance is scheduled for October 2014. For the CAP/Evaluation wells, 16 wells <br />reported one or more VOCs exceeding a PQL, with CAP well AMW-1 having the greatest <br />number of VOCs (nine), including seven measured above a PQL. During the monitoring, <br />period surface water sampling locations were reported dry. For vadose zone <br />monitoring, up to six VOCs were detected in soil -pore liquid samples and approximately <br />23 gallons of liquid was pumped from pan lysimeter FU -03. <br />Under the existing CAP, the GTF pumped nearly 20 million gallons of groundwater <br />removing an estimated 0.49 pounds of VOCs. <br />4.0 REFERENCES <br />California Regional Water Quality Control Board, Central Valley Region, 2014, "Order No. <br />RS -2014-0006 Waste Discharge Requirements for Forward Inc. and Republic <br />Services Inc.
