Soil les B4-35 and B4-85 did not contain detectable concentrations of <br /> ( ) p <br /> hydrocarbons. Soil sample 134-63 had the highest quantified detection of TPH-g at a concentration <br /> of 920 mg/kg. Soil samples 135-14/15 and 135-65 contained detectable TPH-g at concentrations of <br /> 1,500 mg/kg and 1.4 mg/kg, respectively. Soil sample 136-35 also had detectable TPH-g at a <br /> concentration of 2.5 mg/kg. BTEX compounds were detected in the same soil samples at <br /> concentrations up to 88 mg/kg of xylen '�Benzen as o detected in the soil samples. Pr-, 4f J�� <br /> ,� 0� . <br /> DIPE was detected in two of the soil samples analyzed. DIPE was detected in samples 135-50 and <br /> 135-65. MTBE, TBA, ETBE and TAME were not detected in the soil samples. sd , <br /> November 2002 t2 Sit <br /> FOJf <br /> Pifee soil boring(CPT-Iq(�PT-3 and CPT-4)were advanced on-site and off-site(Figure 2)utilizing <br /> CPT technology; at each boring location,lithologic data was collected from the initial CPT boring; <br /> an immediately adj acet twin boring was then advanced to soil samples from selected ths.
