' 14 February 2005 <br /> • AGE-NC Project No 95-0128 <br /> IPage 3 of 6 <br />' the fuel additive methyl tertiary-butyl ether(MTBE) in accordance with EPA Method 8020 <br /> or 8260B <br /> • In addition, to satisfy SPWD Industrial Wastewater Discharge Permit No 01, the effluent <br /> water samples were analyzed for pH (150 1) <br /> 23 INSTALLATION OF SOIL VAPOR EXTRACTION AND GROUND WATER <br /> EXTRACTION EQUIPMENT <br /> 08 September 2004, four 300 lbs granular activated carbon (GAC) vessels for adsorption and <br /> treatment were delivered to the site and Installed within the current fenced remediation enclosure <br /> On 11 October 2004 the 200 cubic foot per minute (CFM) SVE extraction blower was delivered to <br /> the site The piping between the blower and GAC vessels was completed within the fenced enclosure <br /> at the site The SVE system network utilized three-Inch diameter connection between vessels to <br /> optimized the air-stream flow volume The vapor extraction wells were connected to the inlet of the <br /> vacuum blower through a 55-gallon moisture removal drum, equipped with a condensate pump for <br /> water treatment though the ground treatment system <br /> On 01 December 2004 a five horsepower,4 standard cubic foot per minute(CFM) compressor was <br /> installed at site A 36-inch pneumatic pump was installed in extraction well EW-1 While the City <br /> of Stockton revised the ground water discharge permit to a maximum flow rate of 10 gallons per <br /> minute on 01 December 2004(Appendix E) 03 December 2004 the San Joaquin Valley Unified Air <br /> Pollution Control District(APCD)issued an authority to construct(ATC)for the SVE system at the <br /> site <br />' 3.0. FINDINGS <br /> I Analytical results of influent ground water samples and ground water extraction measurements were <br /> used to evaluated the volume of impacted ground water removed and mass of hydrocarbons treated <br /> 3 i ANALYTICAL RESULTS OF WATER TREATMENT SAMPLES <br /> The ground water extraction treatment influent samples were reported by laboratory analysis as <br /> follows <br /> • 16 June 2004 - TPH-g was were detected at a concentration of 1,400 micrograms per liter <br /> (µg11) BTEX compounds were detected at concentrations of 150µg11 of benzene,2 9 [to of <br /> 1 Advanced GeoEn"ronmental,Inc <br /> I <br />
