Summary

No federal limits exceeded in EPA data.

PFAS
Detected, below limit4 of 29 PFAS found at least once. All averages below the federal limits.
Lead
Below action level1.6 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 Dec 2025. Your home's pipes can make yours higher.

What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 1 entry point tested Mar 2025 to Nov 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.

29 PFAS tested, 4 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: 1.6 ppb lead (Jan 2025 – Dec 2025). Below action level

Highest since 2016: 3.1 ppb (Jun 2022).

Monitoring periodLead (90th pct.)

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.

For the official word, read the utility's annual Consumer Confidence Report.

Does Paulding County Water System water have PFAS?
