Presuming the absence of <br /> deeper contamination is confirmed, the data suggest that immediate <br /> mitigation is not necessary to protect ground water. The soils should <br /> clean up through natural bacterial action as long as no new hydrocarbon <br /> is added to the soil. At the end of U�q tanks effective life, the tanks <br /> should be removed along with any remaining contaminated soils The <br /> estimated cost of the soils removal to a depth of 20 to 25 feet and <br /> disposal in a Class 1 disposal site is $94,000. The estimated cost of <br /> backfilling and installation of a new tank system is estimated at <br /> $122,000. <br /> We trust that this information is responsive to your needs at this <br /> time.
