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 limitPFOS above the federal limit in EPA's 2023–2025 testing (PFOS 6.05 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
Lead
Below action level1.4 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 2026. Your home's pipes can make yours higher.
Violations
Resolved1 health-based violation since 2016, most recently Jun 2016. One required an urgent public notice within 24 hours (the kind behind boil-water notices), most recently Jun 2016. What to do if you get a notice.
What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 3 entry points tested Aug 2024 to Feb 2025. "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.

For context: the PFOS average is higher than at 90% of the Massachusetts systems EPA tested.

29 PFAS tested, 3 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 6 samples (reporting limit 9 ppb). About lithium.

Lead and copper

Latest 90th percentile: 1.4 ppb lead (Jan 2026 – Jun 2026). Below action level

Highest since 2016: 2.5 ppb (Dec 2019).

Copper 90th percentile: 1.4 ppm (Jun 2007), action level 1,300 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.

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.
