EPA Finalizes Plan to Clean Up Contaminated Sediment and Surface Water at
Quanta Resources Superfund Site in Edgewater, NJ
Edgewater, N.J. (Sept. 27, 2024) – The U.S. Environmental Protection Agency
has finalized its cleanup plan to address contaminated sediment and surface
water at the Quanta Resources Superfund site in Edgewater, N.J. The release of
the final cleanup plan follows an extensive public comment period and aims to
clean up the Hudson River area impacted by historical industrial activities.
“Finalizing this cleanup plan is a significant step towards restoring the
Hudson River area affected by the Quanta Resources site,” said Regional
Administrator Lisa F. Garcia. “We appreciate the community’s input and
look forward to continuing our work at this site to improve the health of the
Hudson River and this riverside community.”
The finalized cleanup 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, highly concentrated
tar-like material referred to as non-aqueous phase liquid and arsenic.
Under the finalized plan, EPA will oversee work to:
Remove contaminated sediment to depths up to 30 feet and transport it to a
licensed facility for off-site disposal.
Backfill dredged areas with clean sediment.
Place a cap over less contaminated areas to prevent further contamination of
the Hudson River.
Monitor sediment and surface water and capped areas long-term to assess the
effectiveness of the cleanup in preventing the migration of contaminants and
maintaining the caps as needed.
Establish institutional controls such as navigational restrictions, signs
prohibiting swimming, wading, or fishing, and other use restrictions to
protect the cap.
Conduct a pre-design investigation to determine if the 115 River Road pier
building and parking structure could remain in place for an interim period or
would need to be demolished in order for the cleanup to be protective of
people’s health and the environment.
In response to public comments, a notable change from the proposed cleanup
plan is that the final plan does not specify the demolition of the 115 River
Road pier. The EPA will decide after a pre-design investigation if the pier,
which houses offices, parking and a restaurant, needs to be demolished or can
stay temporarily. This decision will depend on whether the contamination
beneath the pier can be dredged or contained without risking the structure’s
safety.
