Suspected contamination source: Firefighting foam used at Naval Weapons Station Earle and Earle Military Sealift Command (U.S. Navy, 2016)
Testing conducted in 2016 by the U.S. Navy showed 1 well above the NJ Department of Environmental Protection (DEP) Interim standard for PFOA and 1 well at or above EPA’s Provisional Health Advisory (PHA) for PFOS*. The wells were likely contaminated by firefighting foam containing PFASs that were used on the site.
*In 2016, the EPA lowered its PHA from a standard of 200 ppt for PFOS and 400 ppt for PFOA to a combined lifetime PFOA/PFOS exposure level of 70 ppt. NJ now has a statewide safe level of 40 ppt for PFOA in effect and a proposed safe level of 14 ppt.
