EPA notes higher PCB levels in Hudson dredging
Federal environmental officials say they believe the amount of contaminated sediment that will need to be dredged from the Hudson River will be “significantly higher” than initially expected.
The federal Environmental Protection Agency has released a preliminary evaluation of last year’s dredging of PCB “hot spots” north of Albany. The dredging was a test run for the far larger Phase 2 of the cleanup, which regulators want to start in 2011.
Dredge crews hired by Fairfield, Conn.-based General Electric last year found greater concentrations of PCBs than expected. In the draft report released Thursday, the EPA suggested reassessing the depth of contamination.
PCBs are considered probable carcinogens. Local GE plants discharged wastewater containing PCBs for decades before the lubricant was banned in 1977.
