EPA Proposes Plan To Continue Cleanup Of Cinnaminson Superfund Site

CINNAMINSON, NJ — The Environmental Protection Agency released a proposed plan on Monday that it said would allow the cleanup of the Superfund site in Cinnaminson and Delran townships to continue.

The agency's latest update calls for "removing contaminated soil and replacing it with clean backfill," according to the Environmental Protection Agency (EPA).

"Groundwater would be addressed using ... in-situ chemical treatment, where chemicals are injected into the area with the highest amount of contamination to break down and decrease the contamination over time," according to the EPA.

"This proposed cleanup plan builds off previous actions and is an important step in fully addressing groundwater contamination at the Cinnaminson site," said EPA Regional Administrator Lisa F. Garcia. "EPA will also continue to investigate and address instances of vapors entering residential homes or commercial structures."

The website at this link provides several ways that the public can provide the EPA with feedback on this latest update.

In 2021 and 2020, the EPA said its cleanup plan consisted of focusing on "highly concentrated portions of the contaminated groundwater near the source areas by using a pump and treat remedy."

Cinnaminson's Superfund site consists of residential, light-to-heavy industrial and historic landfill properties in Cinnaminson and Delran townships, EPA said.

The Cinnaminson Superfund Site was first placed on the EPA's Superfund National Priorities List in 1986, the agency said.
