The U.S. Environmental Protection Agency has announced finalization of an interim plan to clean up contaminated sediment in the upper nine miles of the Lower Passaic River Study Area of the Diamond Alkali Superfund site in New Jersey.
The lower 17 miles of the Passaic River is a study area of the Diamond Alkali Superfund site. While the greatest volume of contaminated sediment lies in the lower 8.3 miles of this 17-mile stretch, contamination in the upper nine miles acts as a continuing source of contamination in the river, affecting fish, wildlife and communities along the riverbanks.
