PFNA in New Jersey well water
In New Jersey, <1% of 20,186 private wells tested between 2002 and 2024 had PFNA above the New Jersey limit (13 ng/L), according to NJDEP.
PFNA is a long-chain forever chemical found near industrial sites and firefighting foam. It is linked to immune and developmental effects and high cholesterol. New Hampshire set its own limit in 2019.

- NJDEP Private Well Testing Act summaries: Share of private wells exceeding each standard in tests required at sale or lease under the New Jersey Private Well Testing Act, September 2002 to December 2024, published by NJDEP. Tests are untreated water at the time of sale or lease, so every well is counted once per transaction. Municipalities with fewer than ten wells are suppressed. Standards are New Jersey's: arsenic 5 ug/L, PFOA 14 ng/L, PFOS 13 ng/L, PFNA 13 ng/L, manganese and iron secondary standards. Uranium and PFAS were added to the required panel in 2021 and 2020, so their well counts are smaller. Retrieved September 9, 2026.
