PFAS test results
Highest average at any one sampling point, from EPA's UCMR 5 testing (2024–2025), against the levels EPA set in 2024. ND = not detected above EPA's reporting level. EPA's comparison rounds like this: an average of 4.05 ppt or more counts as above the 4 ppt PFOA/PFOS limit, and 15 ppt or more counts as above the 10 ppt level for PFHxS, PFNA and GenX.
Hazard index (PFHxS, PFNA, GenX, PFBS mix): 0.00 (limit 1, EPA comparison threshold 1.5).
All 1 detected compound at this system (single highest result)
| Compound | Highest result | Results above reporting level |
|---|---|---|
| PFBA | 22 ppt | 4 of 4 |
Read this as a screening result, not a compliance finding. UCMR 5 samples are occurrence data. Legal compliance is judged on a running annual average from the utility's own monitoring, reported to the state. PFOA and PFOS at 4 ppt are in force; EPA has proposed to rescind the PFHxS, PFNA, GenX and hazard-index levels.
Violations and lead
No health-based violations began since 2021-10-26 in the EPA file for this system.
Lead 90th percentile: 4.0 ppb for the period ending 2025-12-31 (action level 15 ppb). This is a system-wide statistic, not your home's tap; lead usually comes from household plumbing and service lines.
Common questions
Is the tap water in Moline safe to drink?
PFAS were detected at Moline, but every regulated compound averaged under its limit. No health-based violations recorded since 2021-10-26. Lead 90th percentile 4.0 ppb in the sampling period ending 2025-12-31 (action level 15 ppb). This is a summary of public EPA data, not a guarantee about the water at your tap.
Does Moline have PFAS in its water?
Yes. EPA's 2023–2025 testing detected 1 of 29 PFAS compounds at Moline.
Not medical or legal advice. Results describe the utility's system, not your tap. Compare with your utility's annual Consumer Confidence Report.
