How does Oak Grove School compare with other water systems in Payne County?
By EPA's size categories, Oak Grove School is a very small system (500 people or fewer). Payne County has 21 active public water systems. Its population served is well below the county average of 3,550 people per system, and accounts for 0.3% of the 74,559 people reported by systems filed under the county. Across Oklahoma, the 1,254 active systems average 2,907 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Oak Grove School is about half of that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Oklahoma has 84 active non-transient non-community water systems, 6.7% 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 Oak Grove School?
EPA lists Oak Grove School 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. 11 of the 21 active systems in Payne County (52%) are also owned by a local government.
Does Oak Grove School have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in May 2025. The violations listed here began between September 2011 and May 2025. By type: 10 monitoring and reporting and 2 monitoring. The contaminant or rule involved most often is Chlorine (5 of them). EPA lists 11 as resolved and 1 as archived. 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. 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.
