Federal environmental officials say they need to collect more data from the Hudson River before they determine how well six years of dredging completed in 2015 is working to clean up the waterway. The U.S. Environmental Protection Agency on Wednesday released its third review on the cleanup of PCBs from a 40-mile stretch of the river north of Albany. The EPA concluded that while PCB levels in water and fish are going down overall, it needs more data on fish to determine if the cleanup is meeting initial expectations. General Electric removed 2.75 million cubic yards of contaminated sediment from the river bottom under a Superfund agreement with the EPA.
