What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Oklahoma has 864 active community water systems, 69% of the state's 1,254 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 701 Oklahoma systems (56%) list groundwater as their primary source.
Who owns and regulates Kingfisher?
EPA lists Kingfisher as owned by a local government. The OK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 7 of the 11 active systems in Kingfisher County (64%) are also owned by a local government.
Does Kingfisher have drinking water violations?
Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in October 2025. The violations listed here began between October 2024 and October 2025. By type: 6 contaminant level above the legal limit, 4 monitoring and reporting, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (7 of them). EPA lists 7 as archived and 5 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.
