PFAS test results
Highest average at any one sampling point, from EPA's UCMR 5 testing (2023–2024), 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 3 detected compounds at this system (single highest result)
| Compound | Highest result | Results above reporting level |
|---|---|---|
| PFPeA | 6.1 ppt | 3 of 8 |
| PFBA | 5.9 ppt | 1 of 8 |
| PFHxA | 5.1 ppt | 1 of 8 |
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: 28 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 Newport-City of safe to drink?
PFAS were detected at Newport-City of, but every regulated compound averaged under its limit. No health-based violations recorded since 2021-10-26. Lead 90th percentile 28 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.
