How does Loyal compare with other water systems in Kingfisher County?
By EPA's size categories, Loyal is a very small system (500 people or fewer). Kingfisher County has 11 active public water systems. Its population served is well below the county average of 930 people per system, and accounts for 0.8% of the 10,232 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 Loyal 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. 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 Loyal?
EPA lists Loyal 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 Loyal have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2025. The violations listed here began between January 2021 and July 2025. By type: 10 monitoring and reporting and 2 monitoring. The contaminant or rule involved most often is Nitrate-Nitrite (4 of them). EPA lists 10 as resolved and 2 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.
