NEW YORK — Environmentalists are encouraging people to attend a meeting in New York City this week about the Hudson River Superfund cleanup.

The Environmental Protection Agency is holding a meeting in Manhattan on Wednesday to discuss the agency’s recent review of how well the $1.7 billion dredging project is working. In its review, the agency said that while polychlorinated biphenyl levels in fish remain high, more dredging doesn’t seem necessary for now.

But many environmentalists want more PCBs removed from the river. People critical of the EPA’s stance attended two previous public meetings in Poughkeepsie and Saratoga Springs.

Boston-based General Electric removed 2.75 million cubic yards (2.1 million cubic meters) of PCB-contaminated sediment from a 40-mile (64-kilometer) stretch of the upper Hudson through 2015.
