Utility results describe the whole system, measured where water enters the pipes, not your tap. Your home’s plumbing can add lead or copper. 2 numbers we weren’t sure about are held back until a person checks.
EPA testing for PFAS and lithium
EPA’s own nationwide testing (UCMR 5) found these in City of Odessa’s water between Aug 2024 and May 2025. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.
- PFHxS4.9 pptFound in 4 of 4 samples · highest resultNo federal limit in force for this one
- PFBS4.5 pptFound in 4 of 4 samples · highest resultNo federal limit in force for this one
- Lithium48 ppbFound in 4 of 4 samples · highest resultAbove EPA’s health reference level of 10 ppb (a guide, not a legal limit)

What you can do
Nothing here is an emergency notice: if the district has a violation, it must tell customers directly. If you’d like to lower these at your tap, these are the treatments that remove them, and the catalog shows the models certified for each. Ranking is by certified removal; commissions never change the order.

Found: Fluoride
