1 <br /> SECTION 3 <br /> SOIL AND GROUNDWATER INVESTIGATION RESULTS <br />' This section describes the results of the present investigation with respect to identified <br /> contaminant concentrations and distribution in soils along with analytical results of <br /> groundwater sampling <br /> 3.1 Soil Investigation Results <br />' Summaries of laboratory chemical test results for soil samples are provided on Table 1 <br /> Analytical results for the evaluation of petroleum hydrocarbons in soil samples obtained from <br /> borings MW-1, B-1, and B-2 indicated not detected However, analytical results indicate the <br /> presence of total extractable petroleum hydrocarbons as diesel (TEPHd) and motor oil <br /> (TEPHmo) at soil borings B-3 and B-4 Total volatile hydrocarbons (TVH) were detected at <br /> ' soil boring B-4 <br /> At a depth of approximately 20-feet at boring B-3, the TEPHd concentration was reported at <br /> ' 6,900 mg/Kg and the TEPHmo concentration was reported at 7,000 mg/Kg TEPH analyses <br /> of the soil sample obtained from boring B-3 at a depth of 25-feet indicated not detected <br /> Concentrations of TEPH were reported between the depths of 15 to 19-feet at boring B-4 At <br /> boring B-4 TEPHd was reported in samples B4-15', B4-17 5', and B4-19' at concentrations of <br /> 12,000 mg/Kg , 160 mg/Kg , and 4 8 mg/Kg, respectively TEPHmo was also reported in <br /> samples B4-15', B4-17 5', and B4-19' at concentrations of 8,300 mg/Kg , 730 mg/Kg , and <br /> 1,400 mg/Kg , respectnely TVH concentrations were reported for samples B4-15' and B4- <br /> 17 5 at 460 mg/Kg and 2 4 mg/Kg, respectively TEPH analyses of the soil sample obtained <br /> from boring B-4 at a depth of 23-feet indicated not detected for all TEPH compounds and for <br /> TVH <br /> BTEX compounds were not detected in any of the soil samples tested and lead was reported at <br /> concentrations ranging from 2 8 to 6 7 mg/Kg <br /> ' 3.2 Groundwater Investigation Results <br /> ' A summary of laboratory chemical test results for groundwater samples obtained from <br /> monitoring well MW-1 are provided on Table 2 Laboratory results for the evaluation of <br /> petroleum hydrocarbons in water samples obtained from monitoring well MW-1 indicated not <br /> detected for TPH (several fractions), TVH, and BTEX Depth to static water level was <br /> measured using an electronic water level meter On July 10, 1996 depth to static water level <br /> was recorded at 3105 feet below the top of well casing and on October 8, 1996 it was <br /> measured at 30 09 feet <br /> 6 <br /> 1 <br />
