Three 10,000 gallon underground product storage tanks <br /> are situated in the southwest central portion of the site. A <br /> storm water detention pond is situated in the southeastern corner <br /> i <br /> of the site. <br /> j o <br /> The station's leaking underground storage tanks were repaired in <br /> 0 <br /> July 1985 after it had been determined that two of the <br /> j <br /> underground storage tanks had leaked product into the subsurface. <br /> Soil and groundwater contamination have occurred as a result, of <br /> that leakage. The petroleum tontaminati�o tends a short <br /> distance from .the bottom of the tank p int the underlying <br /> `F silty and sandy soils.
