On the basis of the leaching potential calculated using L.U.F.T. <br /> $p g <br /> Manual guidelines,it appears that petroleum hydrocarbons remaining in soil do not present a threat <br /> to the local groundwater quality. It is HLA's opinion that the site meets the requirements for closure <br /> and that no additional work is warranted at this time. <br /> We.trust that this is the information you require at the present time.
