1 <br /> 6 SUMMARY <br /> ' The following summarizes the results of this investigation. <br /> • Residual gasoline hydrocarbons have been detected in soil samples collected near the <br /> ' USTs. TPHG concentrations ranged from below laboratory detection limits to <br /> 3.3 ppm. Benzene concentrations ranged from below laboratory detection limits to <br /> 4.019 ppm. <br /> ' • Residual gasoline hydrocarbons were not detected in soil samples collected near the <br /> dispenser islands. <br /> ' • Groundwater was encountered at approximately 61 feet bgs. <br /> • The groundwater flow direction at the time of measurement was to the east with a <br /> hydraulic gradient of 0.042. Static groundwater was measured at approximately 58 to <br /> 59 feet bgs. The flow direction is away from the location of the municipal well. <br /> O TPHG and BTEX compounds were detected in monitoring well MW-1 and total <br /> xylene isomers were detected in monitoring well MW-2. TPHG and BTEX <br /> 1 compounds were below laboratory detection limits in the groundwater sample <br /> collected from well MW-3. <br /> 1 <br /> 1 <br /> I� <br /> SACW NPJft80S08051470.1BS-95\pas:1 Rev.0,216!96 <br /> 0805-147.01 6-1 <br />
