In addition, groundwater samples were analyzed for fecal Coliform. <br /> TPHD and TPHG analysis was performed using the DHS/LUFT approved method <br /> (Modified EPA Method 8015). BTEX was quantified using EPA Method 8020 <br /> (soil) and EPA Method 607. (groundwater). Fecal coliform was analyzed in <br /> accordance with Standard Methods. All analyses were performed at a DHS <br /> certified hazardous waste laboratory. <br /> Tables 2 and 3 summarize the analytical results for soil and groundwater <br /> samples, respectively. Complete certified analytical reports are presented in <br /> Appendix B. <br /> Soil Sample Analytical Results <br /> A total of five soil samples were collected and submitted for laboratory analysis. <br /> Soil samples collected from each borehole were screened using a photoionization <br /> detector (PID), which measures total ionizable vapors (TiV). The sample from <br /> each borehole having the highest TIV measurement was submitted for chemical <br /> _ analysis. <br /> �. Total Petroleum Hydrocarbons <br /> TPHD was detected in 3 of the 5 samples submitted for analysis (Table 2). <br /> Dectectable TPHD concentrations ranged from 500 mg/kg to 6,800 mg/kg. Sample <br /> MNV-2,collected from a depth of 25.0 to 26.5 feet below ground surface, contained <br /> TPHD at a concentration of 520 mg/kg. TPHD was detected in sample MW-3(25.0 <br /> to 26.5 feet) at a concentration of 500 mg/kg. A TPHD concentration of 6,800 <br /> mg/kg was detected in sample B-1 (25.0 to 26.5 feet). No TPHD was detected in <br /> samples MW-1 (25.0 to 26.5 feet) and B-2 (15.0 to I6.5 feet). TPHG was not <br /> detected in any of the samples submitted for analysis. <br /> ra <br /> Aromatic Hydrocarbons <br /> All soil samples collected were analyzed for BTEX. None of the samples <br /> contained detectable quantities of benzene or toluene. Ethylbenzene was detected <br /> in samples MW-2 (7.2 ug/kg), MW-3 (24 ug/kg) and B-1 (600 ug/kg). Only one <br /> sample(MW-3) contained detectable quantities of xylenes(10 ug/kg). <br /> Groundwater Sample Analytical Results <br /> Groundwater samples were collected from each of the boreholes that were <br /> converted to permanent monitoring wells (MW-1, MW-2, MW-3). A sample from <br /> each well was submitted for analysis. <br /> Total Petroleum Hydrocarbons <br /> All groundwater samples collected were submitted for analysis by TPHD and <br /> TPHG. Neither TPHD nor TPHG were detected in any of the samples submitted <br /> (Table 3). <br /> 5 L.ML/SV132.21/0083 REV p <br />
