EPA has submitted a $36 million proposal
to clean up the nearly 20 acres of soil, sediment, and groundwater contamination at the Sherwin-Williams/Hilliards Creek Superfund Site in Gibbsboro, NJ.
The proposal calls for the excavation and disposal of roughly 67,000 cubic yards of contaminated soil and backfilling the site with clean soil.
EPA also requested to remove contaminated soil and sediment from the Upper Hilliards Creek floodplain. EPA will conduct bioremediation as well to ensure vegetation and wetland area restoration.
The proposal is a followup to separate remediation projects that resulted in a $14 million settlement with Sherwin-Williams in 2017 and a subsequent $2 million cost recovery action by EPA that was settled earlier this year for $1.4 million.
About the Sherwin-Williams/Hilliards Creek Superfund Site
The Sherwin-Williams/Hilliards Creek Superfund Site was a paint and varnish manufacturing facility
until 1977, when the NJ Department of Environmental Protection (DEP) began investigating alleged discharges of paint solvents, lead, arsenic, and other hazardous wastes into the environment.
Nearby properties, known as the Dump Site and the Burn Site, are sources of contaminated soil and sediment that have spread into residential properties and surrounding bodies of water, including Hilliards Creek.
Improperly stored hazardous wastes have also spread contamination to surrounding bodies of water and residential properties, EPA says.
