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 Prague?

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. 16 of the 22 active systems in Lincoln County (73%) are also owned by a local government.
Does Prague have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in May 2025. The violations listed here began between January 2024 and May 2025. By type: 8 monitoring and reporting, 1 monitoring, 1 contaminant level above the legal limit, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (2 of them). EPA lists 6 as archived, 5 as resolved and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
