Before comparing values to limits
- A reported value above a limit isn't by itself a legal violation. Federal compliance for PFOA and PFOS is judged on running annual averages at each sampling point, and the federal deadline hasn't arrived yet.
- Federal limits. EPA's 2024 rule set limits of 4 ppt for PFOA and PFOS, with compliance due in April 2029. In May 2026, EPA proposed letting systems request more time, to April 2031; that proposal isn't final. In May 2026, EPA proposed withdrawing its national limits for PFNA, PFHxS, GenX (HFPO-DA) and a combined limit for PFAS mixtures. The proposal isn't final yet; EPA plans to decide in 2026. New Jersey's own PFNA limit is unaffected. (Status as of November 2026.)
- New Jersey's limits are in effect today: 14 ppt for PFOA, 13 ppt for PFOS and 13 ppt for PFNA.
- Partial-source values. For the Harrison system and Mount Holly system, the PFOA and PFOS values come from the Delaware River Regional Water Treatment Plant section of the report. They describe the surface-water share of supply only; the reports give no PFAS compliance result for these systems' wells.
- Partial-source values. For the Newark Water Department: A footnote to the report's PFAS table says the results represent samples collected from the Belleville Surge Tank, which transmits water into Newark's distribution system from the North Jersey District Water Supply Commission (NJDWSC). The report gives no separate PFOA or PFOS result for water from Newark's own Pequannock plant.
- Partial-source values. For the Passaic Valley Water Commission: These values are from PVWC's Little Falls Water Treatment Plant. The report says most customers get Little Falls water blended with water bought from the North Jersey District Water Supply Commission, whose Wanaque plant reported 4.47 ppt of PFOA and 2.95 ppt of PFOS (highest detected level); water bought from Newark's Pequannock plant was below 1.9 ppt for both.
- No PFAS results. The 2025 reports for the Ocean City system and Penns Grove system contain no PFAS results for those systems.
- Not every New Jersey town is here. Towns were selected where one water system serves most residents, so towns with mixed supply are underrepresented. All towns on this site are listed A to Z.
What PFAS, PFOA, PFOS and PFNA are
PFAS stands for per- and polyfluoroalkyl substances. EPA describes them as a group of thousands of chemicals used in many consumer, commercial and industrial products, and as long-lasting chemicals that break down very slowly over time (EPA, PFAS Explained).
Drinking water limits cover only a few of them. The three in this table are the ones New Jersey sets limits for:
- PFOA (perfluorooctanoic acid): New Jersey limit 14 ppt; federal limit 4 ppt.
- PFOS (perfluorooctane sulfonic acid): New Jersey limit 13 ppt; federal limit 4 ppt.
- PFNA (perfluorononanoic acid): New Jersey limit 13 ppt; federal limit 10 ppt.
EPA's 2024 rule also set limits for PFHxS and GenX (HFPO-DA), which have no New Jersey limit. In May 2026, EPA proposed withdrawing its national limits for PFNA, PFHxS, GenX (HFPO-DA) and a combined limit for PFAS mixtures. The proposal isn't final yet; EPA plans to decide in 2026. New Jersey's own PFNA limit is unaffected. Results are in parts per trillion (ppt), the same as nanograms per liter (ng/L).
How to read the table
PFOA, PFOS and PFNA are three PFAS compounds with drinking water limits. Utilities don't report them the same way, so two numbers in the same column can measure different things. The "What the value is" column says which, in the report's own terms: "highest running annual average", "highest compliance result", "highest single result", "highest average" and "amount detected". Where a report doesn't say whether its figure is a single result or an average, the system's page says so. "Not detected" means every result was below the lab's detection limit; "Not reported" means the report has no result for that compound. Each system's page charts its values against both limits and lists the other PFAS found in EPA's nationwide testing. Hardness for the same systems is in water hardness by water system.
