Mr. Herb Presxler <br /> Letter of Addendum to Closure Report <br /> ' Page Two <br /> was performed to remove the contaminated soils. ETS Environmental <br /> was involved in the. pit sampling' and reported the analytical <br /> results in a closure report dated March 31, 1992 . <br /> As described in the Closure Report of March 31, 1992, two side-wall <br /> 4 <br /> samples and three bottom samples were found non-detectable for the <br /> tested constituents. Soil analyses has shown only minor amounts of <br /> contamination remaining on site, with the total amount to be .less <br /> than one pound of oil & grease. Limited space has prevented <br /> further excavation and, as mentioned in the closurereport, the <br /> ground water is at 65 to 70 feet, with a hard pan preventing <br /> vertical migration. Therefore, this site should be' considered for ' <br /> closure. <br /> Respectively Submitted By: <br /> Roy Austin <br /> Project Geologist <br /> Reviewed By: <br /> �.
