The sixth and final season of dredging the upper Hudson River is now under way, part of an estimated $2 billion Superfund project.
Prior to 1977, GE discharged some 1.3 million pounds of PCBs into the river. A 200-mile stretch of the Hudson down to New York City was listed as a Superfund site in 1984. Cleanup was delayed amid opposition from GE and some residents. GE dropped public opposition after the EPA issued a decision calling for dredging in 2002. The cleanup finally began in 2009.
