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 5 detected compounds at this system (single highest result)
| Compound | Highest result | Results above reporting level |
|---|---|---|
| lithium | 15 µg/L | 4 of 4 |
| PFPeA | 82.5 ppt | 4 of 4 |
| PFBA | 22.5 ppt | 3 of 4 |
| PFHxA | 5.8 ppt | 3 of 4 |
| PFBS | 3.6 ppt | 3 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
1 health-based violation began since 2021-10-26 (1 limit exceedance, 0 treatment-technique; 0 still open). Most recent began 2023-07-01.
| Contaminant group | Violations |
|---|---|
| Coliform bacteria | 1 |
Health-based means a limit exceedance or a missed treatment requirement. Many violations are fixed within weeks; a count says nothing about severity. Missed-sample (monitoring) violations are not counted.
Lead 90th percentile: 1.0 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.
Lithium: highest result 15.3 µg/L. EPA's non-regulatory reference concentration is 10 µg/L (results above 15 are counted as above it). Lithium has no federal drinking-water limit.

Common questions
Is the tap water in City of Texas City safe to drink?
PFAS were detected at City of Texas City, but every regulated compound averaged under its limit. 1 health-based violation recorded since 2021-10-26 (0 not yet closed). Lead 90th percentile 1.0 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 City of Texas City have PFAS in its water?
Yes. EPA's 2023–2025 testing detected 4 of 29 PFAS compounds at City of Texas City.
Not medical or legal advice. Results describe the utility's system, not your tap. Compare with your utility's annual Consumer Confidence Report.
