ME <br /> i <br /> 4 SUBSURFACE CONDITIONS <br /> I � <br /> - i 4.'I Soil <br /> The soils at the site consist primarily of clayey sands and clean sands, <br /> with occasional lenses of clay and silt. Since the sail boring was drilled <br /> through the excavation, gravel fill was encountered to a depth of 16.5 feet. <br /> Sands were encountered from 16.5 to 76 fleet, with one sandy clay <br /> interbed at a depth of approximately 53 to 58 feet. <br /> 4.2 Ground Water <br /> - Ground water was first encountered approximately 69 feet below the <br /> ground surface, and the static water level is approximately 68 feet below <br /> the ground surface. Based upon EMCON's knowledge of the area and on <br /> i topographic Information, the ground-water flow direction is probably <br /> toward the south-southwest. <br /> p19\90519050101d 6 Rev.0 ,July 2,1991 <br /> EM(Of1 Associates <br />
