1 <br /> also masked GPR returns from beneath it One anomalous area was identified approximately 1 meter 13 <br /> feet) east of where MW-14 was found The GPR was successful in identifying the location of the <br /> transite water line running along the south side of the yard <br />' 5_3 Soil Analytical Results <br /> Twelve soil samples were collected and submitted to the laboratory for chemical analysis A <br />' summary of soil analytical data is presented in Table 1 <br />' TPHd and FOCs were not detected above their respective laboratory reporting limits in any of the <br /> twelve soil samples submitted for analysis TPHg was detected in four of the twelve soil samples at <br /> concentrations ranging from 0 9 to 6 3 mg/kg BTEX was detected in seven soil samples at <br /> concentrations ranging from 0 008 to 0 75 mg/kg for benzene, 0 007 to 1 0 mg/kg for toluene, 0 012 <br /> to 0 16 mg/kg for ethylbenzene, and 0 078 to 0 73 mg/kg for total xylenes <br />' 5_4 Groundwater Analytical Results <br />' TPHg was detected in the groundwater sample collected from MW-14A at a concentration of 1,300 <br /> µg/l BTEX was detected at concentrations of 360 µg11 for benzene, 130 µg/l for toluene, 27 µg/1 for <br /> ethylbenzene, and 94 µg/1 for total xylenes FOCs were not detected in the groundwater sample <br />' obtained from MW-14A <br /> TPHg, TPHd, and BTEX were detected in the vertically discreet groundwater samples collected from <br /> the CPT soil boring TPHg and TPHd were only detected in the shallowest groundwater sample <br /> (CPT-1-55-58') at concentrations of 1,400 and 170 µg/l, respectively BTEX compounds were <br />' detected in each of the four groundwater samples at concentrations ranging from 0 6 to 72 µg/1 for <br /> benzene, 0 9 to 44 µg/l for toluene, 0 5 to 51 µg/l for ethylbenzene, and 1 8 to 38 µg/l for total <br /> xylenes FOCs were not detected in each of the groundwater samples with the exception of tert-butyl <br /> alcohol detected at a concentration of 110 µg/l in sample CPT-1-55-58' A summary of groundwater <br />' analytical data is presented in Table 2 <br /> 1 <br /> Project No S8475-06-02 -11- December 26,2001 <br />
