How does Yale compare with other water systems in Payne County?
By EPA's size categories, Yale is a small system (501 to 3,300 people). Payne County has 21 active public water systems. Its population served is about 65% below the county average of 3,550 people per system, and accounts for 1.6% 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 community water system reports serving 6,703 people, so Yale is well below that figure.
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. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 299 Oklahoma systems (24%) list purchased surface water as their primary source.
Who owns and regulates Yale?
EPA lists Yale 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 Yale have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in November 2025. The violations listed here began between October 2021 and November 2025. By type: 4 monitoring and reporting, 3 contaminant level above the legal limit, 2 monitoring, 1 reporting, 1 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (5 of them). EPA lists 8 as resolved and 4 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.
