Y <br /> 1 <br /> Soil Characterization <br /> Soils have been characterized from previous soil investigations <br /> performed at the former underground tank site. In the area of the <br /> LItanks, the site is underlain by low permeability silts and clays with <br /> +: discontinuous layers of clayey sand to a depth of approximately 26 feet <br /> below grade. These silts. and clays are underlain by clean to silty <br /> sands estimated to have a moderate to high permeability. <br /> i L <br /> Table 1-2 <br /> Results of Soil and GroundwaterArud vws <br /> by ERM-West, Manch 1991 <br /> Boring(B) #/ TPH-Diesel Benzene Toluene Ethyibenzene Xylenes <br /> Well (MW) # <br /> f Soil B-16 1,300 mg/kg <0.5 µg/kg <0.5 µg/kg <0.5 gg/kg 380 gg/kg <br /> Water B-16 (HP-1) 150 mg/l NC NC NC NC <br /> _.
