4.0 RESULTS <br /> 441 Soil Analytical Results <br /> Soil samples collected from MW8, the onsite "C" zone well, contained concentrations of TPHg, <br /> ' BTEX, and/or MTBE at depths ranging from approximately 55 to 65 feet bgs- TBA was detected <br /> in soil samples collected from MW8 at a depth of 65 feet bgs. The soil sample collected from <br /> boring MW8 did not contain a detectable concentration of TPHd. <br /> The soil samples collected from borings MW7c on February 25, 2004 and MW9c on February <br /> 18, 2004 did not contain detectable concentrations of TPHg, TPHd, BTEX, MTBE, TAME, <br /> ' TBA, ETBE, DIPE, 1,2-DCA, or EDB. Analytical results of soil samples are summarized in <br /> Table 1. Laboratory data sheets and chain-of-custody documentation are presented in Appendix <br /> ' B. <br /> 4.2 Groundwater Analytical Results <br /> 4.2.I First Quarter Sampling <br /> The groundwater samples collected from MW1 through MW4, MW8, and EWI contained <br /> detectable concentrations of TPHg and BTEX constituents. Groundwater samples collected from <br /> wells MWS and MW6a contained detectable concentrations of TPHg but no BTEX constituents. <br /> ' Groundwater samples from MWI through MW9c and EWI did not contain detectable <br /> concentrations of TPHd. <br /> Groundwater samples collected from MW9c contained detectable concentrations of benzene, <br /> toluene, and xylenes. Groundwater samples collected from MW6b, MW7a, MW7b, MW7c, <br /> MW9a, and MW9b contained no detectable concentrations of TPHg or BTEX constituents. <br /> Groundwater samples collected from MWI, MW2, MW4, MW6b, MW7c, MWS, and EWI <br /> contained detectable concentrations of MTBE and groundwater samples from well MW4 and <br /> ' MW6a contained detectable concentrations of TBA. Groundwater samples collected from wells <br /> MWI and MW4 contained detectable concentrations of 1,2-DCA. <br /> ' Analytical results of groundwater samples are summarized in Table 4. <br /> 4.2.2 Second Quarter Sampling <br /> The groundwater samples collected from MW1 through MW4, and EWI contained detectable <br /> ' concentrations of TPHg and BTEX constituents. Groundwater samples collected from MW6a <br /> contained detectable concentrations of TPHg but no BTEX constituents. Groundwater samples <br /> from MWI through MWIOc and EWI did not contain detectable concentrations of TPHd. <br /> SAEnviromental126823-Jamarlreportslsum.doc 6 <br />
