New York's conservation chief is challenging the effectiveness of recently completed dredging of contaminated sediment from the upper Hudson River, saying unacceptably high levels of industrial waste were left behind.
Commissioner Basil Seggos says dredging improved the Hudson but the federal Environmental Protection Agency needs to re-evaluate the six-year project and get objective analysis in its ongoing review of fish, water and sediment data.
His letter to the EPA comes a year after General Electric finished dredging a 40-mile stretch of the river for PCBs in a federal Superfund project.
Until 1977, GE factories discharged into the river more than 1 million pounds of polychlorinated biphenyls, considered a probable carcinogen.
The EPA says it will review consider any new information, noting and New York had agreed with the cleanup plan.
