Lead-Contaminated Soil Removed at Central Steam Facility
Historical analyses of storm water samples collected from the recharge area located east of the Central Steam Facility (CSF), Building 610, showed elevated levels of lead. Concentrations of lead in soils at the recharge outfall, which received storm water runoff from the area around the CSF and portions of North 6th Street and Cornell Avenue, and adjacent parking lots, significantly exceeded background levels. An extensive area of shallow soils containing lead was identified downstream of the outfall pipe by soil sampling conducted in 2000 and 2002. Approximately 1,500 tons of lead-contaminated soil was removed. The soil cleanup was conducted under Operable Unit IV; the Central Steam Facility was identified as Area of Concern (AOC) 5.
