What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 1 entry point tested Jun 2023 to Apr 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, 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 2026 – Jun 2026). Below action level

1 reported result in EPA's records is far above anything physically plausible (likely a unit or data-entry error) and is not used in the summary.

Highest since 2016: 2.2 ppb (Jun 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.

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.
