(Forward), GeoLogic Associates (GLA) is submitting this <br /> summary report for the Forward Landfill groundwater treatment facility (GTF)to fulfill <br /> the requirements established by Waste Discharge Requirements(WDRs) Order No. R5- <br /> 2003-0080. <br /> The Forward Landfill is an active facility located at 9999 South Austin Road in Manteca, <br /> California. Following detection of volatile organic compounds (VOCs) in groundwater, a <br /> Corrective Action Program (CAP)was implemented at the site in 1994 which includes <br /> five groundwater extraction wells (EW-1, EW-2, EW-3, EW-3B, and EW-4) that pump <br /> groundwater through an air stripper treatment system to remove VOCs. The treated <br /> groundwater is discharged to an infiltration pond north of the Austin Road Unit of the <br /> Forward Landfill. Included herein is a summary of the water quality monitoring results <br /> for the GTF at the Forward Landfill for the third quarter 2009. <br /> CAP MONITORING PROGRAM RESULTS <br /> Under WDR Order No. R5-2003-0080, effluent monitoring consists of a continuous <br /> record of flow; monthly analysis of pH, specific conductance (EC), and VOCs; quarterly <br /> analysis for total dissolved solids (TDS); and annual analysis of 24 metals. In addition, <br /> influent is monitored semiannually for pH, EC, turbidity, and VOCs. Del-Tech <br /> Geotechnical Support Services (Del-Tech)performs the operation and maintenance <br /> (O&M) duties and performs bimonthly inspections for the Forward Landfill GTF. The <br /> results of the bimonthly inspections are presented below and summarized in Table 1; the <br /> field monitoring logs and laboratory results are attached. <br /> Operational Summary - As shown in Table 1, between May 26 and September 24, 2009, <br /> except during downtime for maintenance, the CAP system operated continuously and <br /> treated approximately 17,100,320 gallons of groundwater at an average flow rate of 139 <br /> gallons per minute, or 199,803 gallons per day.
