What this record covers
- CITY OF ODESSA's water system as a whole, as reported to EPA UCMR 5.
- 29 PFAS compounds, each with its own result.
- Samples taken 2024-08-21 to 2025-06-16.
What is unknown
- The water at your tap. Building plumbing isn't in this record.
- PFAS not listed in the 29 above were not reported in these records.
- Levels since the last sample have not been published.

Is there PFAS in Odessa tap water?
In EPA's UCMR 5 testing of CITY OF ODESSA (2024-08-21 to 2025-05-05): PFBA 5.4 ng/L (no federal or state limit), PFBS 4.5 ng/L (EPA health advisory 2,000), PFHxS 4.9 ng/L (limit 10) and the other 26 PFAS tested not detected. "Not detected" means below the lab's reporting limit, not proven zero.
What are the federal PFAS limits?
EPA's 2024 drinking-water rule set maximum contaminant levels of 4.0 ng/L for PFOA and for PFOS, and 10 ng/L for PFHxS, PFNA and HFPO-DA (GenX). In May 2026 EPA proposed keeping the PFOA and PFOS limits, with the option of until 2031 to comply, and rescinding the other three. Until a final rule, all five limits apply. Results above them today are above the limits in force.
How do I remove PFAS from my tap water?
Reverse-osmosis systems and filters certified to NSF/ANSI 53 or 58 for PFOA/PFOS reduction are the proven options at the tap. Check the certifier's listing (NSF, WQA or IAPMO) for the exact model, and replace cartridges on schedule.
