The U.S. EPA has directed NL industries to conduct remediation of the Raritan Bay Slag Superfund site in Old Bridge and Sayreville, NJ. Soil and sediment at the site are contaminated with lead, that comes from a lead-containing material that was used to build a seawall and jetty and the beach. Cleanup is expected to cost $79 million dollars.
The EPA identifies NL industries as the party responsible for the cost of the cleanup. Cleanup will take place in three areas that are contaminated with lead containing materials. Materials include lead slag, which is a byproduct of metal smelting. The three areas are the Laurence Harbor seawall adjacent to the Old Bridge Waterfront Park, an area that includes the western jetty in Sayreville and extends from the Cheesequake Creek Inlet into Raritan Bay, and roughly 50 acres of Margaret’s Creek.
Cleanup will be conducted under EPA oversight. It will require digging up and dredging of contaminated soil and sediment. Contaminated materials will be disposed of at permitted disposal facilities, and excavated areas will be restored with clean material. Monitoring and testing will be conducted throughout the cleanup to ensure that public health and the environment are being protected. The public will be notified about the progress of the cleanup.
