. • Gloves <br /> • Vacuum, PSI, and temperature gauges <br /> • Pitot tube with fittings, anemometer <br /> • Misc piping and connectors, flexible piping <br /> ' SHORT TERM VAPOR EXTRACTION TEST (day one) <br /> 1 The purpose of the vapor extraction test is to determine the radius of influence A snort term <br /> VET will be performed using well VW2 on the first day and a long term VET will be performed <br /> 1 on well VW3 the second day <br /> Pre-test Procedures <br /> 1 Measure depth-to-water in extraction well (VW2) <br /> 2 At extraction wellhead VW2, install PVC riser and all piping to connect to IC engine <br /> 3 Install pitot tube, gauges, temperature gauge, etc for monitoring influent stream <br /> 4 Install monitoring caps on all observation wells, hookup magnehelic gauges set to zero <br /> 5 Record vacuum or pressure readings at all monitoring points prior to testing <br /> Vapor Extraction Test Procedures <br />' 1 Start up blower, initiate vapor extraction at low flow and step up flow <br /> rate/vacuum <br /> throughout the test at 30 to 60 minute intervals if possible <br /> 2 Monitor flow, temperature, influent and effluent concentrations with FID, vacuum, and <br /> pressure for extraction and observation wells at 15 minute intervals <br /> 3 Monitor response in observation wells at 15-minute untervals <br />' 4 Check knockout drum regularly, empty as needed Reduce/flow vacuum if pulling to <br /> much water <br /> 5 Collect an influent and effluent vapor samples after approximately 15 minutes of <br /> operation for laboratory analysis of TPHg/BTEX by 8015/8020 and MTBE and <br /> oxygenates by 8260 <br /> 6 Collect an influent sample at the end of the test for laboratory analysis of TPHg/BTEX by <br /> 8015/8020 and MTBE and oxygenates by 8260 <br /> 7 Vapor extract for one to two hours Continue operation as long as possible until field <br /> readings stabilize or a maximum of two hours <br />
