Ifficakriffianc <br /> • reported in the soil samples from boring g P2 The highest concentration of contaminants in <br /> boring P2 were identified in the soil samples collected between 20 feet bgs and 40 feet bgs <br /> The vertical extent of contamination in boring P2 was not fully defined Groundwater was <br /> not encountered during this phase of the investigation <br /> 2.4 Wallace-KuW, &Associates, Inc. hwestigation <br /> In February 1993, Wallace-Kuhl, & Associates, Inc drilled eight soil borings (MWI <br /> through MW3, and B1 through B5) at the locations shown 1n Figure 3 Borings BI throw <br /> gh <br /> B5 were drilled around the perimeter of the former UST excavation to depths between 45 and <br /> 50 feet bgs, and borings MWl through MW3 were drilled to depths of 60 feet bgs and had <br /> four-inch diameter groundwater monitoring wells installed into them In addition to these <br /> borings, three hand augered samples (DI-1, DI-2, and DI-3) were collected at a depth of five <br /> ve <br /> feet bgs beneath the former fuel dispensers <br /> A total of 60 soil boring samples and three groundwater samples were collected from <br /> the bonngs and wells The samples were analyzed for TPH as JP4 het fuel, TPH-G, TPH-D, <br /> TPH-motor oil using modified EPA Method 8015, and BTEX using EPA Method 8020 <br /> Analytical results identified no detectable concentrations of TPH-G, TPH-D,.1� <br /> TPH-motor oil or benzene in any of the soil samples TPH as het fuel was identified in the <br />' 15, 20, 25, and 30 foot bgs samples from boring B3 Concentrations of aromatic <br /> hydrocarbons in these samples ranged from 3 mg/kg of ethylbenzene in the five-foot sample <br /> collected from boring DI 1, to 1,580 mg/kg of total xylenes in the 20 foot sample from <br />' boring BI <br /> Groundwater samples were collected from wells MWl, MW2, and MW3 on February <br /> 10, 1993 The samples were analyzed for TPH-G, TPH-D, TPH as JP4 jet fuel, TPH as <br /> motor oil, and BTEX Analytical results identified no detectable concentrations of petroleum .� <br />` fuel hydrocarbons or BTEX in the_groundwater sire,, A summary of analytical results for <br /> the water samples is included as Table 2 <br /> 6 <br />
