Revised LFR Levine Fricke <br /> month, although LFR with DTSG concurrence may decide to terminate the test at an <br /> earlier stage depending upon the interim results of the pilot test <br /> 7.3 Dual-Purpose Soil Vapor Extraction/Sparge Well Equipment <br /> The wells to be used ,in the Phase III pilot test program will be the rune wells installed <br /> as part of this pilot test program plus existing groundwater monitoring wells MW-09 <br /> and G-06 <br /> The air sparging system will include insWiatioin of the in-well sparging assemblies in <br /> dual-purpose wells FSEW-3 and PSEW-5, aboveground and below ground routing of <br /> conduit, tubing, and wire from the sparging well to the air sparginglozone sparging <br /> panel, and the mstallatiotn of the one air spargtnglozone spargmg panel <br /> The GAS m-well sparging equipment components to be installed in the spargmg well <br /> include. <br /> • a 1-inch-diameter in well air sparge point installed at she lower inwrval of the <br /> sparging well <br /> • a fluid-filled expandable packer installed between the upper and lower screened <br /> intervals to isolate the soil vapor extraction well portion from the air sparging <br /> portion of the well <br /> The main components of the air sparging/ozone spugmg system panel will include <br /> 4 s l 10-volt electrical outlet installed near the panel to provide power to the ozone <br /> sparging system <br /> an ozone generator, with pulsed spargtng across a dielectric tube, which will be <br /> taken off line during the GAS pilot study <br /> • a 3/4-horsepower air compressor <br /> • a programxr able timer/controller <br /> 41 appurtenant electrical equipment <br /> 7.4 SVE/GAS pilot Test <br /> The monitoring parameters and frequency of inomtonng during the GAS pilot test are <br /> identified in Table 2 In addition to the groundwater monitoring,Table 2 outlines the <br /> routine monitoring that will be performers to evaluate pressure and concentratson trends <br /> in the soil vapor extraction wells during thls phase of the pilot study. The data will be <br /> used to assess the effectiveness of the operation of the SVE system <br /> *V.&YFC%5-t,odi-m-W173 dw Ire Page 23 <br /> Ot7ZL I'd 82 t009b600 i 01 906b ?N9 OTS 3NO I 63 9N I n:31 �Ul NJ 60 9T FO, 60 'illi' <br />
