Analysis of <br /> four of the soil samples (MW1-10, MW2-10, MW2--15, and MW3-10) did not detect <br /> concentrations of TPH—D, TPH—G, or BTEX at or above the method detection limits. Analysis <br /> of the other two soil samples (MW1-15 and MW3-15) did not detect TPH—G or BTEX <br /> concentrations at or above the method detection limits, but did detect TPH—D at the method <br /> detection limit of 1 mg/kg. The soil sample analytical results are summarized in Table 2. <br /> Table 2 <br /> Summary of Soil Sample AnalyticalResults <br /> Depths are in feet <br /> Concentrations are in milligrams per kilogram <br /> Sample ID Depth B T E X TPH—G TPH—D <br /> MWI-10 10 ND ND ND ND ND ND <br /> MWI-15 15 ND ND ND ND ND 1 <br /> MW2-10 10 ND ND ND ND ND ND <br /> MW2-15 15 ND ND ND ND ND ND <br /> MW3-10 10 ND ND ND ND ND ND <br /> MW3-15 15 ND ND ND ND ND 1 <br /> DETECTION LIMITS 0.005 0.005 0.005 0.005 1 1-0 <br /> 0'jor\) <br /> Notes: ND = None detected } { <br /> BTEX = Benzene, toluene, ethylbenzene, and total xylenes <br /> TPH—G = Total petroleum hydrocarbons as gasoline <br /> TPH—D = Totaltroleum hydrocarbons as diesel � 114 <br /> Pe Y �V <br /> A groundwater sample from each well was analyzed in the laboratory for TPH—D, TPH—G, and <br /> BTEX. Groundwater samples MW1 and MW2 did not contain detectable concentrations of TPH-- <br /> D, TPH—G, or BTEX. Analysis of groundwater sample MW3 did not detect concentrations of <br /> TPH—D, toluene, or ethylbenzene above method detection limits, but did detect 55 micrograms <br /> per liter (ug/L) TPH—G, 1.4 ug/L benzene, and 1.7 ug/L total xylenes.
