“The Hudson River PCB Superfund dredging project has been a success... This project is the most extensive dredging project undertaken in the nation, and its success is a historic achievement for the recovery of the Hudson River. It was also a success for the local economy — providing about 500 jobs at its peak.”

Replanting the Riverbed After Dredging

The habitat reconstruction program GE performed in the Hudson River was one of the largest aquatic replanting programs ever undertaken. Hundreds of thousands of aquatic plants, including wild celery, American pondweed and broad-leaved arrowhead plants, along with other species, were planted.

The program was initiated in 2010, following the first season of dredging in 2009. GE’s crews planted vegetation and seeded areas along the shoreline called riverine fringing wetlands. In addition, divers planted submerged aquatic vegetation in the riverbed below the water’s surface. More than 100,000 individual plants and tubers were installed in areas that had previously been dredged and backfilled.

The program was challenging to implement. The large quantities of suitable plants needed to support the program were difficult to locate. GE worked closely with its habitat contractors, and EPA, which approved and supervised the program, to resolve issues.
