Are there risks at the site now?

The site is bounded by private residential properties to the north and northwest. While the majority of the site is privately held in a trust, U.S. Fish and Wildlife Service owns about 40 acres of the site, which is part of the larger Great Swamp National Wildlife Refuge that surrounds the site on the south, east and west. The site also includes a shooting range and ballfield owned by Green Village. Potenially exposed human populations were evaluated for existing and future site conditions and include landscapers, recreators, trespassers, off-site residents, construction workers and future on-site residents.

Analytical results of surface and subsurface soil, wetland sediment, surface water and groundwater samples taken to date, found elevated levels of arsenic, lead, mercury, polycyclic aromatic hydrocarons, pestcicides, phthalates, PCBs, VOCs, SVOCs, freon compounds, dioxin and furans, on both the privately and federally owned portions of the site. A baseline human health risk assessment was completed in 2014 and identified potential site risks to trespassers and future residential occupants. The baseline risk assessment was evaluated in 2016 to assess data gap sampling results and the risks identified remain the same. Access to the site is limited by surrounding wetlands and the property owners have posted no trespassing signs at the Britten Road access point. The land owners closely monitor for trespasser acitivity. A screening level ecological risk assessment was completed in 2013 and was followed by a baseline ecological risk assessment which is underway.

EPA is currently conducting a Remedial Investigation/Feasibility Study to further define the nature and extent of contamination at the site. Once the study is complete, EPA can determine the best cleanup method for the site. EPA ensures community participation throughout the remedial process by meeting with residents and affected stakeholders, issuing public notices and updating fact sheets. A site profile has been established on the EPA website to keep the community informed of recent progress at the site. Additionally, an EPA Community Involvement Coordinator is assigned to the site and can address specific community concerns as they arise.
