The Diamond Alkali Superfund Site is made up several properties in Newark, the Lower Passaic River Restoration Project Study Area, and the Newark Bay Study Area. EPA treats each as a unique part of its investigation and cleanup efforts, and EPA’s work on the Passaic River is one component of this three-part effort.
- The Lower Passaic River Restoration Project is a partnership of federal and New Jersey agencies designed to cleanup contaminated sediments, improve water quality, restore degraded shorelines, restore and create new habitats and enhance human use along a 17-mile stretch of the lower Passaic and in several tributaries from Dundee Dam near Garfield, to Newark Bay.
- The former Diamond Alkali Company operated a pesticides manufacturing plant in Newark's Ironbound neighborhood. Sampling at the site and in the Passaic River immediately adjacent to the plant has revealed high levels
of dioxin, an extremely toxic chemical. Under the Superfund
program, the Occidental
Chemical Corporation is required to perform cleanup work at several properties in Newark, in the adjacent portion of the Passaic River, and in the Newark Bay Study Area.
- The Newark Bay Study includes the bay and portions of the Hackensack River, Arthur Kill and Kill Van Kull, and will assess the nature and extent of contamination in the Newark Bay area and develop cleanup plans to address those problems, as necessary.
