- PFAS
- Detected, below limit3 of 29 PFAS found at least once. All averages below the federal limits.
- Lithium
- Above screening levelHighest result 48 ppb. EPA uses 10 ppb to decide what to study further. It is not a health limit, and there is no federal limit for lithium. About 1 in 4 systems tested were above it.
- Lead
- Below action level0 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 2024. Your home's pipes can make yours higher.
- Violations
- Resolved2 health-based violations since 2016, most recently Feb 2021. 2 required an urgent public notice within 24 hours (the kind behind boil-water notices), most recently Feb 2021. What to do if you get a notice.

- Read City of Odessa's annual water quality report (Consumer Confidence Report). It lists every regulated contaminant tested and is usually on the utility's website or mailed with your bill, and you can also request it at (432) 335-4104. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Aug 2024 to Jun 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.
| Contaminant | Highest average |
|---|---|
| PFOA Not detected Limit 4 ppt | – |
| PFOS Not detected Limit 4 ppt | – |
| PFHxS Detected, below limit Limit 10 ppt | 4.53 ppt 45% of the limit |
| PFNA Not detected Limit 10 ppt | – |
| HFPO-DA (GenX) Not detected Limit 10 ppt | – |
| Hazard Index (a combined score for PFHxS, PFNA, GenX and PFBS, where above 1 is over the limit) Detected, below limit Limit 1 | 0.45 |
| PFBS Detected, below limit Guideline 2,000 ppt | 3.85 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 1.35 ppt |
| PFHxA Not detected Guideline 3,000 ppt | – |
29 PFAS tested, 3 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
Detected in 4 of 4 samples. Highest result 48 ppb. EPA's non-enforceable screening level is 10 ppb. Above screening level The screening level is how EPA decides what to study further, not a health limit. There is no federal limit for lithium and no filter is certified to remove it. About lithium.
Lead and copper
Latest 90th percentile: 0 ppb lead (Jan 2022 – Dec 2024). Below action level
Highest since 2016: 10.1 ppb (Dec 2020).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2022 – Dec 2024 | 0 ppb |
| Jan 2021 – Dec 2021 | 0 ppb |
| Jan 2018 – Dec 2020 | 10.1 ppb |
Earlier results (9)
| Jan 2015 – Dec 2017 | 2.78 ppb |
| Jan 2014 – Dec 2014 | 2.55 ppb |
| Jan 2010 – Dec 2012 | 3.15 ppb |
| Jan 2007 – Dec 2009 | 2.74 ppb |
| Jan 2004 – Dec 2006 | 4.1 ppb |
| Jan 2001 – Dec 2003 | 3.5 ppb |
| Jan 1998 – Dec 2000 | 1.5 ppb |
| Jan 1997 – Dec 1997 | 1.6 ppb |
| Jan 1996 – Dec 1996 | 1.7 ppb |
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.
Violations
| When | What happened |
|---|---|
| Oct 2019 – Feb 2021 2 times | The water was too cloudy too often in a month. Cloudiness can shield germs from disinfection. Urgent public notice required What that means EPA record: Interim Enhanced Surface Water Treatment Rule · Monthly Turbidity Exceed (Enhanced SWTR) (limit ) Resolved |
1 unresolved monitoring or reporting violation: Public Notice.
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.
Earlier EPA testing (2013–2020)
| Contaminant | Highest | Guideline |
|---|---|---|
| Manganese | 12.3 ppb | 300 ppb |
| Chromium-6 | 0.12 ppb | – |
| Strontium | 2.7 ppm | 1.5 ppm |
| Molybdenum | 11 ppb | 40 ppb |
| Vanadium | 14 ppb | 21 ppb |

Is Odessa tap water safe to drink?
Most of Odessa gets its water from City of Odessa. City of Odessa had 2 health-based violations since 2016, all since resolved. EPA testing found no PFAS above the federal limits. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.
Does Odessa water have PFAS?
Yes. EPA's 2023–2025 testing of City of Odessa found 3 PFAS at least once. None of the averages were above the federal limits.
