The test <br /> is scheduled for October 22, 1993. <br /> OBJECTIVES <br /> The main objectives of the test are: to collect operation data to evaluate the feasibility and <br /> efficiency of vapor extraction as a soil remediation alternative for the petroleum hydrocarbon <br /> impacted soil; to determine the vapor flow rates, petroleum hydrocarbon concentrations, system <br /> vacuums, etc. in order to establish the design criteria for engineering design of a soil vapor <br /> extraction system; and, to select the apparent best alternative for off-gas treatment. <br /> VAPOR TEST EQUIPMENT <br /> The one day test will be performed using a blower with carbon for off-gas treatment. The major <br /> components are: 1) a regenerative blower system with a 5 hp blower, inline filter, vacuum <br /> gauges, and ambient air dilution valve; 2) two 200-pound vapor phase granular activated carbon <br /> vessels connected in series with influent and effluent sample ports; 3) a condensate removal <br /> Proj DiXL-N0T1FX.VEr <br />
