(AGE)has <br /> prepared this work plan for a soil vapor extraction(SVE)pilot test at 1301 West Kettleman Lane, Lodi, California <br /> (site). Recently, four SVE wells(VW-1 thorugh VW-4)were installed at the site in December 2005. A site plan <br /> depicting all well locations and site specifics is included with this email. <br /> I <br /> An 8-hour SVE pilot test is proposed at this site for Wednesday, 12 April 2006. The 8=hour pilot test will be conducted <br /> at the site utilizing a 2%-horsepower, regenerative vacuum blower manufactured by FUJI; the vacuum blower is rated <br /> at a maximum 150 cubic feet per minute. The inlet of the vacuum blower will be directly routed to the well head at <br /> VW-2, connected by 2-inch diameter PVC piping. The outlet of the vacuum blower will be directly routed through two <br /> 400-pound, vapor-phase activated carbon'adsorption canisters located adjacent the vacuum blower. 110 AJ. dA4-'%'J <br /> Air-tight, 2-inch diameter PVC well caps fitted with attached Magnehelic (Dwyer)vacuum gauges will be attached to <br /> wells VW-1, VW-3, VW-4,MW-1, MW-2, MW-3 and the induced vacuum will be measured(i.e. inches of water) at <br /> these monitoring points; the induced vacuum will be monitored in 30-minute intervals during the pilot test and recorded <br /> in inches of water. <br /> Additionally,the air stream from extraction well VW-2 will be monitored for the presence of organic vapor using an <br /> organic vapor analyzer(OVA) equipped with a PID. The vacuum applied at SVE well VW-2 will cause hydrocarbons <br /> in the vadose zone to volatilize and flow to VW-2 and through the regenerative vacuum blower. From the vacuum <br /> blower, the extracted hydrocarbon vapor will be processed and adsorbed through the carbon canisters as part of the <br /> treatment process. Hydrocarbon concentrations in the SVE effluent stream will be measured at hourly intervals utilizing <br /> an OVA. <br /> During the 8-hour SVE pilot test,the air flow rate at the inlet of the vacuum blower will be monitored using a Dwyer <br /> DS-200 flow sensor(inches of water); the flow rate will be converted to SUM using a manufacture (Dwyer) supplied <br /> conversion chart. Flow rates will be measured in 30-minute intervals and documented in standard cubic feet per minute <br /> (scfin) and inches of water of differential pressure. <br /> A total of five vapor samples (air flow samples) will be collected at the start-up and at two-hour intervals thereafter <br /> from the inlet of the extraction well to measure concentrations of extracted hydrocarbon vapor. The samples will be <br /> collected in Tedlar bags using a hand air-vacuum pump. Following sample collection, the samples will be placed in a <br /> covered container and transported under chain of custody to a California Department of Health Services-certified <br /> analytical laboratory for analysis. Each sample will be analyzed within 72 hours for TPH-g,BTEX, and MTBE in <br /> accordance with EPA Methods 8015M and 802018021. <br /> 4/12/2006 <br />
