gallons per minute, or 179,114 gallons per day. During the monitoring period,the GTF is <br /> calculated to have removed approximately 2.17 pounds of VOCs. <br /> During the monitoring period the GTF shut down because of a power outage on October <br /> 14, 2009; Del-Tech restarted the GTF on October 15, 2009. On November 17, 2009 <br /> extraction well EW-2 went offline for no apparent reason; Del-Tech restarted extraction <br /> well EW-2 on November 18, 2009. On November 24, 2009 the GTF shut down because <br /> of back pressure in the effluent line that was crushed by heavy equipment. Del-Tech <br /> completed repairs to the 15-inch PVC effluent line with heavier piping and the GTF was <br /> restarted on December 2, 2009. <br /> Influent and Effluent Monitoring—During the monitoring period, effluent samples were <br /> collected monthly from the GTF and submitted for analysis of VOCs by EPA Method <br /> 8260B,the November 18, 2009 effluent sample was also analyzed for TDS and 24 <br /> dissolved metals. In addition, an influent sample was collected on November 18, 2009 <br /> and submitted for analysis of VOCs by EPA Method 8260B and turbidity. Table 1, <br /> summarizes the field and analytical results for the GTF during the fourth quarter 2009 <br /> monitoring period. As-shown on Table 1, four VOCs were detected in the influent <br /> sample,while no VOCs were detected in any of the effluent samples collected during the <br /> monitoring period. <br /> GLA hopes that the information provided herein is sufficient for your records.
