Kettleman Lane,Lodi CA. <br /> Harlin, <br /> In accordance with our telephone conversation, dated 10 April 2005,Advanced GeoEnvironmental, Inc..(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 /> An 8-hour SVE pilot test is proposed at this site for Wednesday, 12 Apri12006. The 8-hour pilot test will be conducted <br /> at the site utilizing a 2'/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 directlyrouted 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. <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 SCFM 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 /> (scfm) 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 /> 4/10/2006 <br />
