Working to Restore Nature <br /> The composite soil sample from the drill cuttings did contain concentrations of TPHg, <br /> ethylbenzene and total xylene isomers above laboratory detection limits but benzene and <br /> toluene were below laboratory detection limits (Table 1) Results for lead, reactivity, <br /> corroslvlty, and lgnitabslity are shown on Table 1 and in the attached laboratory reports <br /> SUMMARY AND CONCLUSIONS <br /> Trace concentrations of BTEX were detected In soil near the southern region of the <br /> northwestern dispenser island at depths between 46 5 and 515 feet bsg Analytical data <br /> indicate that BTEX concentrations decrease with depth, and are below detection limits at <br /> 60 feet bsg TPHg concentrations were below detection limits in all soil samples <br /> Groundwater was not encountered in the soil boring However, based on existing <br /> groundwater monitoring wells within a 2-mile radius, groundwater occurs at approximately <br /> 70 feet bsg In our opinion, the detected BTEX concentrations do not warrant additional <br /> delineation at this time <br /> 1117shoo/123013 01 3 <br />
