Oklahoma City’s 2025 water report finds no drinking-water violations

Oklahoma City reported zero drinking-water violations in its annual 2025 Drinking Water Quality Report, released June 30, 2026.

The city said its water met or exceeded applicable standards set by the U.S. Environmental Protection Agency and the Oklahoma Department of Environmental Quality.

Annual report covers the city water system

The document is Oklahoma City’s annual Consumer Confidence Report, also described by the city as its Drinking Water Quality Report. It concerns the city’s municipal drinking-water system.

The city’s reported total for drinking-water violations was zero. The finding is the compliance result stated in the city’s report; it is not an allegation, estimate or proposed target.

In reporting the result, the city identified applicable EPA and Oklahoma DEQ standards as the benchmarks its water met or exceeded. The city did not report a drinking-water violation in its announcement of the 2025 report.

Report year and release date are different

The report is identified as the 2025 water-quality report, but Oklahoma City released it on June 30, 2026. The dates distinguish the year addressed in the annual report from the date the city made the report public.

That distinction means the zero-violation result is the city’s stated finding for the report identified as 2025. The available city material does not establish a separate compliance finding for every later period.

Why the report matters

The report provides a public-health and infrastructure update for people served by Oklahoma City’s water system. It records the city’s stated assessment of whether its water complied with the applicable federal and state standards cited in the report.

The city system is the scope of the report. The finding should not be extended to private wells or other water sources in the Oklahoma City metropolitan area, which are not established by the available source material as covered by the report.

No subsequent city action, additional deadline or later water-quality finding was identified in the approved source material. The confirmed development is the June 30, 2026 release of the annual report and the city’s statement that it recorded zero drinking-water violations.
