Third Quarter 2006 Groundwater Treatment <br /> Facility Monitoring Report <br /> Forward Landfill WDR Order No. R5-2003-0080 <br /> 1.0 Summary <br /> This Third Quarter 2006 Monitoring Report for the Forward Incorporated (Forward) <br /> Landfill Groundwater Treatment Facility (GTF)presents the monitoring results for influent <br /> and effluent.This report was prepared as stipulated by the Central Valley Regional Water <br /> Quality Control Board (CV Water Board) Waste Discharge Requirements (WDR) Order <br /> No. R5-2003-0080,which was adopted on April 25,2003. <br /> Following review of the information presented in this document,the following conclusions <br /> have been made: <br /> • The GTF operated for 2,109 hours between June 30 and October 1,2006,at 94.2 percent <br /> uptime,and treated 28.686 million gallons of groundwater. During this period,the GTF <br /> removed approximately 1.8 pounds of volatile organic compounds (VOC). <br /> • During third quarter 2006,the effluent samples collected in August and September met <br /> WDR Order No.R5-2003-0080 for VOCs. No VOCs were detected. <br /> ® Tetrachloroethylene (PCE) was detected in the effluent sample collected in July 2006,at a <br /> concentration slightly above the detection limit.The PCE detection appeared to be <br /> anomalous and might have resulted from cross contamination during sample collection, <br /> transport,or analysis. After the GTF was shut down,restarted,and resampled,no VOCs <br /> were detected in the August effluent sample. <br /> 2.0 operational Summary <br /> The GTF operated for 2,109 hours between June 30 and October 1,2006,at 94.2 percent <br /> uptime,and treated 28.686 million gallons of groundwater at an average flow rate of <br /> 227 gallons per minute,or 0.327 million gallon per day. During this period,the GTF <br /> removed approximately 1.8 pounds of VOCs.
