1 the estimated non-detect line (<1 mg/l (ppm)) for TPH-gasoline in <br /> ground water is shown on Figure 4-3 <br /> Lead. Analyses were also performed for total and organic lead in soil <br /> and water samples. Samples collected during the removal of the <br /> tank by EHJ Construction showed total lead results of 2.6 mg/kg for <br />' soil and 6 mg/l for water (note that water samples were unfiltered). <br /> Subsequent samples were analyzed for organic lead. These later <br /> sample results (for both soil and water) were below detection limits <br />' (Tables 4-1 and 4-2). The analytical findings suggest that the tank <br /> contained unleaded gasoline, and the total lead values reported are <br /> representative of background levels in area soils. <br />' RD1Ri Numerous tests have been completed for EDB. All of the <br /> results were reported to be below detection limits. <br />' ColifQrm Bacteria, At the request of the Health Department, a water <br /> sample was collected from MW1 immediately after the well was <br /> constructed, and the sample was then analyzed for Coliform <br />' Bacteria The test was performed because the well lies within 50 feet <br /> of a sanitary sewer force main lying west of the well. The test result <br /> reported a most probable count of 1,600 coliform bacteria/100 <br />' milliliters. <br /> Summary of Findings <br /> The tank formerly located at Site #1 was found to be in poor condition <br /> when it was removed This poor condition resulted in a release of <br /> petroleum products to soil and ground water. Subsequent <br />' investigation activities defined the extent of the release as being <br /> limited to a localized area of soil and ground water in the vicinity of <br /> the former tank location Potential remedial action alternatives for <br />' this site will be evaluated in Section 7 <br /> 4-5 <br />
