Summary

No federal limits exceeded in EPA data.

PFAS
Detected, below limit3 of 29 PFAS found at least once. All averages below the federal limits.
Lead

Resolved1 health-based violation since 2016, most recently Jan 2016.
What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 4 entry points tested Aug 2023 to May 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.

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

Detected in 2 of 10 samples. Highest result 12.6 ppb. EPA's non-enforceable screening level is 10 ppb. Below screening level The screening level is how EPA decides what to study further, not a health limit. There is no federal limit for lithium and no filter is certified to remove it. About lithium.

Lead and copper

Latest 90th percentile: 1.91 ppb lead (Jan 2023 – Dec 2025). Below action level

Highest since 2016: 2.6 ppb (Dec 2016).

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.
