How does Corner Market compare with other water systems in Cleveland County?
By EPA's size categories, Corner Market is a very small system (500 people or fewer). Cleveland County has 70 active public water systems. Its population served is well below the county average of 3,084 people per system, and accounts for less than 0.1% of the 215,909 people reported by systems filed under the county. Across Oklahoma, the 1,254 active systems average 2,907 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Corner Market is well below that figure.
What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Oklahoma has 306 active transient non-community water systems, 24% 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 Corner Market?
EPA lists Corner Market as privately owned. 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. 52 of the 70 active systems in Cleveland County (74%) are also privately owned.
Does Corner Market 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 2023 and July 2025. By type: 9 monitoring and 3 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (9 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.
