tdepth of 4 and 6. 84 feet. This conclusion was developed by evaluating the <br /> analytical results (Table 3 [Parker]) . <br /> rSoils containing petroleum product constituents exist to groundwater. Based on <br /> the criteria outlined in the LOFT Field Manual, these soils are a potential <br /> threat to underlying groundwater quality. Groundwater was encountered between <br /> the depths of 4.57 smf 6. 84 feet during the investigation. Data collected <br /> indicate a groundwater flow direction of approximately 120 degrees southeast <br /> with a gradient of .0015. The estimated groundwater seepage velocity ranges from <br />' .0020 and . 0015 feet per year. <br /> Gasoline product exists on the groundwater surface in Monitoring Well #' s 1 and <br />' 4. Groundwater sample analytical results from W4 suggest that petroleum product <br /> constituents in the groundwater extend less that 20 feet from the former <br /> underground gasoline storage tank location. <br /> 1 <br /> 1 <br /> 114 <br />
