Soil Charmter 1zation <br /> Soils have been characterized from previous sail investigations <br /> performed at the former underground tank site. In the area of the <br /> tanks, the site is underlain by low permeability silts and clays with <br /> discontinuous layers of clayey sand to a depth of approidrnately <br /> 2 feet <br /> clean below grade. These silts and clays are underlain by y <br /> sands estimated to have a moderate to high permeability. <br /> Table 1-2 <br /> ,JA�, '+� 7 Resultsof,Soil and <br /> R4f-Wes4M AnalysesGroundwater 91 <br /> 71 j <br /> Boling(B)#1 PH-DieFQi Benzene Toluene —fb nzene xylenes <br /> Well (MW) # <br /> <0.5 µmg <0.5 µmg <0,5 µmg 380µg/kg <br /> Soil B-16 1,300 ri g NNC <br /> NC C NC <br /> Water B-16(HP-1) 1�, m;�l /l <0.3µgll <br /> MW-1 0.37 mg/1 <br /> 40.3µg11 40.3µg/l 40.3µg <br /> µg <br /> MW-2 0.33 mgll <br /> <0.3 /l <0.3µg/1 <0.34g/1 <0.3µg/l <br /> MW-3 0.15 mg/1 <br /> <0.3µp_ <0.3µg/l <0.3µg/1 <0.3ug/l <br /> MW-4 0.14 mg/l 40.3µg/1 <0.3µg/1 40.34g/1 <0.3µg/l <br /> NC -Not collected due to lack of water in the sampler. <br /> i <br /> 1-5 <br />
