The wells will be screened at depth intervals of <br /> drilling <br /> feet <br /> feet and 30 to 60 eet below grade, respectively.anal sis and log the <br /> activities, EVAX will sample soils for laboratory Y <br /> soils encountered in accordance with the Unified Soil C1auridercchapn <br /> System. EVAX will arrange for transport of the soil samples, <br /> of custody documentation, to an analytical laboratory. <br /> EQUIPMENT INSTALLATION <br /> The system equipment, including <br /> unit, and <br /> andbic feet accumulator/waterer mlutknockou� <br /> catalytic incinerator, p P 9 an <br /> device, will be delivered to the site, installed ecificatuonsentfoorpad, the <br /> connected to the extraction system.
