Problems/Comments
During the removal of an abandoned pipeline (2004) diesel range organics (DRO) contaminated soil was discovered under two vertical segments of the line at the location of a former above ground storage tank (AST). 585 cubic yards of impacted soil were excavated and thermally remediated. Elevated levels of DRO (1,230 mg/kg) remained in the excavation base beyond the reach of the excavator. Soils borings in 2010 determined the extent of contamination was limited.
