Problems/Comments
Historic diesel oil spill discovered in 7/99. Preliminary sampling isolates 550 gallon AST with secondary containment at the site from contaminated soil. Estimated <100 cubic yards of contaminated soil, shallow bedrock, no GW seen in test pits and boring. Also contamination present in a small wetland area near the heliport. Separate source area from above. VCP candidate. Low Priority ranking by AHRM based on preliminary sampling and no surface contamination.
