We observed that: <br /> o The soil at the project site is generally sandy and relatively <br /> permeable. <br /> o The contaminants at the site are almost exclusively volatile <br /> organic compounds. <br /> o The minimum depth to ground water at the site is approximately 30 <br /> feet. <br /> Since the vacuum produced by a vapor extraction system within a soil mass <br /> extends a significant radial distance from the extraction wells, <br /> strategically placed wells can be used for removing volatile organic <br /> compounds from beneath buildings and other permanent structures. <br /> i <br /> The results of our preliminary investigation and the available information <br /> u concerning the area of contamination at the site indicated that a vapor <br /> extraction system was an appropriate installation at Guild (Dunlap, 1984). <br /> : <br /> 41-87-137 2 <br /> `s � <br />
