Summary
PFAS above the 2024 federal limits. Systems have until 2029 to meet the PFAS limits.
Is it an emergency? No: PFAS limits are about years of exposure, not a glass of water, and nothing in EPA's data calls for you to stop drinking the water today. If your utility ever issues a boil-water or do-not-drink notice, follow it.
- PFAS
- Above limitPFOA above the federal limit in EPA's 2023–2025 testing (PFOA 7.22 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level0 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 ending Dec 2025. Your home's pipes can make yours higher.
- Violations
- Resolved3 health-based violations since 2016, most recently Jun 2024. One required an urgent public notice within 24 hours (the kind behind boil-water notices), most recently Jun 2024. What to do if you get a notice.
- Pregnant, or mixing baby formula with tap water? Babies drink more water for their size, so PFAS exposure matters more for them. Consider bottled water or a filter certified for PFAS for formula, and ask your doctor. Health effects.
- To lower your PFAS exposure now, a home filter certified for PFAS reduction works (reverse osmosis, or activated carbon certified to NSF/ANSI 53 or 58). Filters for these results.
- 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.
- Got a boil-water or do-not-drink notice? What each notice means and what to do.
- Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
- Read Butler Water Dept's annual water quality report (Consumer Confidence Report). It lists every regulated contaminant tested and is usually on the utility's website or mailed with your bill, and you can also request it at (973) 919-7628. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Feb 2023 to Nov 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 Above limit Limit 4 ppt | 7.22 ppt 1.81× 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 Detected, below limit Guideline 6,000 ppt | 1.6 ppt |
| PFHxA Not detected Guideline 3,000 ppt | – |
New Jersey has its own PFAS limits. PFOA 14 ppt (this system's highest average: 7.22 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.
For context: the PFOA average is higher than at 72% of the New Jersey systems EPA tested.
29 PFAS tested, 2 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: 0 ppb lead (Jan 2025 – Dec 2025). Below action level
Highest since 2016: 13.2 ppb (Jun 2019).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2025 – Dec 2025 | 0 ppb |
| Jan 2024 – Dec 2024 | 0 ppb |
| Jan 2023 – Jun 2023 | 1.71 ppb |

| Jan 2012 – Dec 2014 | 8.81 ppb |
| Jan 2009 – Dec 2011 | 2.36 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
| When | What happened |
|---|---|
| Jun 2024 | The water was cloudier than allowed at least once. Cloudiness can shield germs from disinfection. Urgent public notice required What that means EPA record: Interim Enhanced Surface Water Treatment Rule · Single Turbidity Exceed (Enhanced SWTR) (limit ) Resolved |
| Jan 2021 – Jul 2021 2 times | The water chemistry that keeps lead from dissolving out of pipes was outside the range the state set. EPA record: Lead and Copper Rule · WQP Entry Point/Tap Treatment Technique Non-Compliance (limit TT ) Resolved |
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.

For the official word, read the utility's annual Consumer Confidence Report.
