All 110 New Jersey systems above a limit
Every New Jersey community water system whose UCMR 5 results averaged above a 2024 federal PFAS limit, largest first. Systems that were not tested are not listed: not tested is not the same as not detected.

Which limits were exceeded
| PFAS | Federal limit | Systems above it |
|---|---|---|
| PFOA 5 million people | 4 ppt | 108 |
| PFOS 2.8 million people | 4 ppt | 56 |
| PFHxS | 10 ppt | 0 |
| PFNA 15,900 people | 10 ppt | 2 |
| GenX (HFPO-DA) | 10 ppt | 0 |
| Hazard Index 4,060 people | 1 | 1 |
"–" in the table above means not detected. A system can be above more than one limit. EPA proposed in May 2026 to rescind the PFHxS, PFNA, GenX and Hazard Index limits. That proposal is not final.

Method
For each system we average each entry point's UCMR 5 results (non-detects count as zero, complete sets of samples only) and compare the highest entry-point average with the 2024 federal limit, using EPA's rounding. This is how EPA compares UCMR 5 results to the limits in its own data summary, and our national counts match EPA's published table within 2% (how we check). Results are monitoring data from 2023–2025, not compliance determinations, and treatment installed since then is not reflected. Full method.
Questions
How many New Jersey water systems have PFAS above the limit?
110 of the 245 New Jersey community water systems EPA tested in 2023–2025 (45%) had at least one entry-point average above a 2024 federal PFAS limit. They serve 5.1 million people. Nationally the share is 11%.
Are these systems violating the law?
Not yet. Systems have until 2029 to meet the 2024 limits, and EPA has proposed moving the PFOA and PFOS deadline to 2031 and rescinding the other limits. EPA's UCMR 5 results are monitoring data and do not determine compliance.
Which systems were tested?
EPA's UCMR 5 tested every community water system serving more than 3,300 people and a representative sample of smaller ones. Systems that were not tested have no federal result, which is not the same as having no PFAS.
