Second Quarter 2003 Groundwater Monitoring/Remediation Status Report <br />' Moore Petroleum Bulk Plant,5491 F Street,Banta,California <br /> Page 5 <br /> Modifications from Standard Monitoring Pro rim: <br /> None <br /> REMEDIATION SYSTEM SUMMARY - <br /> Soil Vapor Extraction System <br /> System description: , <br /> Gasoline vapors are extracted from the subsurface through'three monitoring/vapor wells (VEW-' ' <br /> 3/MW=8, MW-1,.and VEW-4/MW-7) and two vapor extraction wells (VEW-1 and VEW-2). The <br /> wells are manifolded together with PVC piping in the remediation compound before connecting <br /> to the extraction system (Figure 2). The vapor 'extraction system is a King Buck'®, 100 cf n, ; <br /> catalytic.oxidizer model No. MMC-5A, utilizing.a positive-displacement blower as-a vacuum. <br /> source: <br /> System startup date: June 17, 2002 <br /> Current system mode; Catalytic operation since startup. <br /> Active.extraction wells: ' VEW-1 through VEW4 k <br /> Inactive extraction wells/reason: MW-1 F <br /> ' Status of system operation during reporting period/rea'sons for downtime: <br /> During this reporting period, from March 25, to.June 19, 2003, the SVE system did not operate <br /> continuously. According to hour meter readings and field data, the system operated a total of <br /> 60.7 days. The.SVE system was found shut down on May 22, with no obvious reason for the <br /> shut down. The system was restarted and data was collected.as normal. On June 5, the SVE <br /> system'was shut down following sampling and maintenance. to allow vapor concentrations to <br /> rebound. The system was restarted during the following site visit however there.was no.evidence <br /> of a concentration increase in the influent yapor stream. <br /> Table 5 summarizes extraction and emission` data- from sampling events that .are normally <br /> performed at the.beginning of'each month: The flow rates and analytical data are used to <br /> calculate approximate pounds of hydrocarbons extracted System results are shown below. <br /> System performance totals: <br /> Pounds of TPH removed: 457 pounds (72.5 gallons) this quarter/ <br /> 4,369 pounds (693 gallons)-total f <br /> Pounds of benzene removed: 0.0 pounds this quartei/1.4,pounds total - <br /> r <br />
