NEW YORK (Sept. 29, 2023) - The U.S. Environmental Protection Agency (EPA) has extended the public comment period for its proposed cleanup plan to address contaminated sediment and surface water at the Quanta Resources Superfund site in Edgewater, New Jersey to November 6, 2023. The original public comment period was scheduled to end on October 6, 2023. EPA previously held a public meeting at the Edgewater Community Center on July 25, 2023, to explain the new cleanup proposal to the public.

The cleanup outlined in the proposed plan will address the sediment and surface water contamination in an area of the site called Operable Unit 2 (OU2). Sediment in OU2 is contaminated with polycyclic aromatic hydrocarbons (PAHs), highly concentrated tar-like material referred to as non-aqueous phase liquid (NAPL), and arsenic. Under the proposed plan, EPA would oversee work to:

• Demolish the 115 River Road pier structure and remove other pilings and structures within the contaminated area, to access and remove contaminated sediment underlying the pier structure.
• Remove contaminated sediment to depths ranging from 10 to 30 feet and take it to a licensed facility off-site for disposal.
• Place a cap over less contaminated areas of the river bottom to lock in residual contamination.
• Establish “institutional” controls such as navigational restrictions, signs prohibiting swimming, wading, or fishing, and other use restrictions to protect the cap.
• Monitor sediment and surface water long-term to assess the effectiveness of the cleanup in preventing the migration of contaminants from sediment to surface water and maintaining the cap as needed.

Written comments on the proposed plan may be mailed or emailed by November 6, 2023, to Thomas Dobinson, Remedial Project Manager, U.S. Environmental Protection Agency, 290 Broadway – 19th Floor, New York, NY 10007, Email: Dobinson.Thomas@epa.gov.
