What's in Odessa, TX tap water
2 contaminants in Odessa, TX's water sat at or above a federal limit, led by TTHM at 1.2x the limit.
- !2 contaminants at or above a federal limit — worst is TTHM at 1.2x
- !1 open monitoring or reporting violation
- !1 contaminant within 20% of a limit
- !14 of 27 core regulated contaminants reported — 13 never appear in this report
+How this score is calculated
Every system starts at 100. Points come off for measured levels, for the federal violation record, and for how much of the core regulated set the utility actually reported. All three inputs are the utility's own published numbers and EPA's own records.
- −27 contaminants at or above a federal limit
- −4 contaminants within 20% of a limit
- −0 open health-based violations
- −3 open monitoring / reporting violations
- −4 health-based violations resolved in the last 5 years
- −8 core regulated contaminants never reported (14/27)
A 90–100 · B 80–89 · C 70–79 · D 60–69 · F below 60. A system reporting under a third of the core set is capped at C however clean its numbers look — a short report is not a clean bill of health.
Full grading methodology, constant for constant →What to worry about
- TTHM1.2× the federal limit2.53–96.4 ug/L · limit 80 ug/L
Long-term exposure above the federal limit is linked to liver, kidney, and central-nervous-system effects and increased cancer risk.

- Chloramine86% of the federal limit3.45 mg/L · limit 4 mg/L
Holds disinfection further into the pipe network, but is regulated under the same residual-disinfectant cap as chlorine.
