Fourth Quarter 2002 Groundwater Monitoring/Remediation Status'Report <br /> Moore Petroleum Bulk Plant,5491 F Street,Banta,-California ' <br /> i i <br />{�• Page 5 - <br />#` Modifications from Standard.Monitoring Program, <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 /> 3/1\4W=8, MW-1, and VEW-41MW-7) and two vapor extraction wells (VEW-2 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 cubic feet <br /> per minute (cfm), Catalytic Oxidizer Model No. MMC-5A, utilizing a positive-displacement <br /> blowef.as a vacuum source. ' <br /> System startup date: June 17,2002 <br /> Current system mode: Catalytic operation since startup. a <br /> s Active extraction wells: VEW=l through VEW-4 <br /> Inactive extraction wells/reason: MW-1 ' <br /> Modifications made during reporting periodlreasons 'or modifications: <br /> None <br /> Status of system operation during reporting periodlreasons for downtime: <br /> During.-this reporting period, from September. 20 to December 27, 2002, 'the VES operated <br /> continuously for approximately 95 days according to hour meter readings recorded in the field. ' <br /> Table 5 summarizes extraction and emission data from sampling events that;are normally <br /> t performed at the beginning of each month. The flow rates and analytical data are used to . <br /> calculate approximate pounds of hydrocarbons extractedand- averaged between the sampling- <br /> events to form the following.results. <br /> System performance totals: <br /> Pounds of TPH_removed:.,• 1.,465 pounds (232 gallons) this quarter/ <br /> 2,236 pounds (355 gallons) total <br /> Pounds of benzene removed: 0.5 pounds this quarter/1.2 pounds total . <br />
