Buys water from N.J.D.W.S.C. – Wanaque North Water System. Treated water bought from another system can carry that system's contaminants.
Summary
No federal limits exceeded in EPA data.
- PFAS
- Detected, below limit1 of 29 PFAS found at least once. All averages below the federal limits.
- Lead
- Below action level2.07 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period Jan 2026 – now, still in progress (results reported so far). Your home's pipes can make yours higher.
- Violations
- None health-basedNo health-based violations since 2016.
- Built before 1986, or not sure what your service line is made of? Check your service line and test your tap. Utility data can't show your pipes.

PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Jan 2023 to Oct 2023. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.
| Contaminant | Highest average |
|---|---|
| PFOA One sample above limit Limit 4 ppt | 3.28 ppt 82% of the limit |
| PFOS Not detected Limit 4 ppt | – |
| PFHxS Not detected Limit 10 ppt | – |
| PFNA Not detected Limit 10 ppt | – |
| HFPO-DA (GenX) Not detected Limit 10 ppt | – |
| Hazard Index (a combined score for PFHxS, PFNA, GenX and PFBS, where above 1 is over the limit) Not detected Limit 1 | – |
| PFBS Not detected Guideline 2,000 ppt | – |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
New Jersey has its own PFAS limits. PFOA 14 ppt (this system's highest average: 3.28 ppt), PFOS 13 ppt (this system's highest average: not detected), PFNA 13 ppt (this system's highest average: not detected). State compliance is judged on the state's own sampling, so ask the utility or the state program whether it meets them.
29 PFAS tested, 1 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.
Lithium
Not detected in 4 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 2.07 ppb lead (Jan 2026 – now (in progress)). Below action level
Highest since 2016: 10.6 ppb (Dec 2017).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2026 – now (in progress) | 2.07 ppb |
| Jan 2025 – Dec 2025 | 4.5 ppb |
| Jan 2024 – Dec 2024 | 3.62 ppb |

| Jan 2020 – Dec 2020 | 5.48 ppb |
| Jan 2019 – Dec 2019 | 6.08 ppb |
| Jan 2018 – Dec 2018 | 4.53 ppb |
| Jul 2017 – Dec 2017 | 10.6 ppb |
| Jan 2017 – Jun 2017 | 6.2 ppb |
| Jan 2013 – Dec 2015 | 2.9 ppb |
Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.
Violations
Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.
Earlier EPA testing (2013–2020)
| Contaminant | Highest | Guideline |
|---|---|---|
| Manganese | 9.47 ppb | 300 ppb |
| Chlorate | 190 ppb | 210 ppb |
| Chromium-6 | 0.059 ppb | – |
| Strontium | 0.064 ppm | 1.5 ppm |

Questions
Is Bayonne tap water safe to drink?
Most of Bayonne gets its water from City of Bayonne. City of Bayonne has no health-based violations since 2016. EPA testing found no PFAS above the federal limits. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.
Does Bayonne water have PFAS?
