<br /> 4.0 RESULTS e
<br /> 4.11 Soil Analytical Results
<br /> The soil samples collected from borings SBS and MW4 had no detectable concentrations of
<br /> TPHg, BTEX, MTBE, TAME, TBA, ETBE, DIPE, 1,2-DCA, or EDB
<br /> The soil samples collected from boring MW5 at depths of 30 5 and 40 5 feet bgs contained
<br /> detectable concentrations of TPHg, toluene, ethylbenzene, and xylenes The sample collected
<br /> from boring MW6 at a depth of 35 feet bgs contained detectable concentrations of TPHg,
<br /> toluene, ethylbenzene, and xylenes
<br /> The soil sample collected from MW7 at 45 ft bgs contained detectable concentrations of 1,2-
<br /> DCA MTBE, TAME, TBA, ETBE, DIPE, 1,2-DCA, or EDB were not detected in any soil
<br /> samples collected from borings MW4, MW5, and MW6, though the detection limits were
<br /> elevated in the MW5 samples from 30 5 and 40 5 feet bgs and MW6 sample from 35 feet bgs due
<br /> to the high concentrations of TPHg noted previously
<br /> Analytical results of soil samples are summarized In Table 3 Laboratory data sheets and chain-of-
<br /> custody documentation are presented in Appendix C
<br /> 4.2 Groundwater Analytical Results
<br /> The groundwater sample collected from CPT1 contained no detectable concentrations of TPHg,
<br /> BTEX, MTBE, TAME, TBA, ETBE, DIPE, 1,2-DCA, or EDB
<br /> The groundwater samples collected from soil boring SBS and wells MW I, MW2, MW3, MW5,
<br /> MW6 and MW7 contained detectable concentrations of TPHg and some or all of the BTEX
<br /> constituents
<br /> The groundwater samples collected from wells MW1, MW2, MW3, MW4, and MW7 contained
<br /> detectable concentrations of MTBE and 1,2-DCA The groundwater samples collected from soil
<br /> boring SBS and wells MW5 and NM contained detectable concentrations of 1,2-DCA
<br /> Additionally, the sample collected from MWI, MW2, MW3, and MW7 contained detectable
<br /> concentrations of TBA None of the groundwater samples collected contained detectable
<br /> concentrations of TAME, ETBE, DIPE, or EDB
<br /> Analytical results of groundwater samples are summarized In Table 2 Laboratory data sheets and
<br /> cha>n-of-custody documentation for groundwater samples are contained in Appendix C
