What you can do

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.

New York has its own PFAS limits. PFOA 10 ppt (this system's highest average: not detected), PFOS 10 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, 0 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: 3 ppb lead (Jan 2026 – Jun 2026). Below action level

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.

Total ever recorded, incl. paperwork

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.

Questions

Is Buffalo Water Authority water safe to drink?

Buffalo Water Authority 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 Buffalo Water Authority water have PFAS?

EPA tested Buffalo Water Authority for 29 PFAS between Feb 2023 and Nov 2023 and none were detected above the reporting limits (about 2 to 20 ppt depending on the chemical).

What is the lead level in Buffalo Water Authority water?

The most recent 90th-percentile lead result for Buffalo Water Authority is 3 ppb, for the period ending Jun 2026. The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
