SVE PILOT TEST CALCULATIONS <br /> June 5, 1997 <br /> Exxon Service Station No 7.3708 <br /> 2705 Country Club Boulevard <br /> Stockton, California <br /> L Purpose <br /> These calculations are performed to estimate the petroleum hydrocarbon removal rates achieved <br /> during the SVE pilot testing on SVE cluster wells VEW-1 and VEW-3 <br /> II Test Well Sail Vapor Flow Rates <br /> Soil vapor velocities and temperatures were measured at the effluent stack during each test using an <br /> anemometer and a thermometer This data winch is presented below will be used to calculate the <br /> average soil vapor flow rate from each of the four well casings Field data sheets are included in <br /> Enclosure D <br /> Depth to Soil Vapor Influent <br /> Ground Water Velocity Soil Vapor TPPH as <br /> Test Well Time (ft) ftl�mm� Temperature (°F) gasoline (ppmv) <br /> VEW-1 15 00 41 500 100 93 <br /> VEW-1 1600 37 450 94 NS <br /> VEW-1 1700 39 400 92 73 <br /> Average- 39 450 95 83 <br /> VEW-3 1130 80 2,100 110 <2 4 <br /> VEW-3 1230 75 2,300 112 NS <br /> VEW-3 13 30 7 1 2,500 111 <2 4 <br /> Average 75 2,300 111 <2 4 <br /> LRP007 809 <br />
