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, PFOS above the federal limit in EPA's 2023–2025 testing (PFOA 8.5 ppt vs a limit of 4 ppt, PFOS 6.5 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level5.1 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 Jun 2025. Your home's pipes can make yours higher.
- Violations
- None health-basedNo health-based violations since 2016.
- 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.

- Read North Attleboro 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 (508) 695-7790. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 4 entry points tested Apr 2024 to Oct 2024. "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 | 8.5 ppt 2.13× the limit |
| PFOS Above limit Limit 4 ppt | 6.5 ppt 1.63× the limit |
| PFHxS Detected, below limit Limit 10 ppt | 3.5 ppt 35% of the limit |
| 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) Detected, below limit Limit 1 | 0.35 |
| PFBS Detected, below limit Guideline 2,000 ppt | 5.5 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 5.5 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 7 ppt |
| PFPeA Detected, no limit | 10.5 ppt |
| PFHpA Detected, no limit | 4.5 ppt |
For context: the PFOA average is higher than at 94% of the Massachusetts systems EPA tested and the PFOS average is higher than at 93% of the Massachusetts systems EPA tested.
29 PFAS tested, 8 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 8 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 5.1 ppb lead (Jan 2025 – Jun 2025). Below action level
Highest since 2016: 10 ppb (Dec 2024).

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 | 1.5 ppb | 300 ppb |
| 1,4-Dioxane | 0.097 ppb | 0.35 ppb |
| Chromium-6 | 0.11 ppb | – |
| Chlorate | 140 ppb | 210 ppb |
