General Electric has begun dredging for PCBs in the Hudson River, twenty-five years after the contamination was deemed a federal Superfund site. GE discharged as much as 1.3 million pounds of PCBs into the Hudson before PCBs were banned in 1977. The contaminated sediment will be transported by train to a hazardous waste site in Andrews, Texas, near the New Mexico border. The Sierra Club in Texas has opposed the plan. Neil Carman said, “All they’re doing is relocating toxic waste. They’re moving a problem from one location to another [and] creating problems for future generations to solve.” While GE is paying to clean up the river, the company is still challenging the constitutionality of the Superfund law in federal court.
