How does Red Rock compare with other water systems in Noble County?
By EPA's size categories, Red Rock is a very small system (500 people or fewer). Noble County has 11 active public water systems. Its population served is well below the county average of 949 people per system, and accounts for 2.8% of the 10,436 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 Red Rock 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 Red Rock?
EPA lists Red Rock 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. 9 of the 11 active systems in Noble County (82%) are also owned by a local government.
Does Red Rock have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in February 2026. The violations listed here began between September 2024 and February 2026. By type: 4 monitoring and reporting, 4 contaminant level above the legal limit, 2 monitoring and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (4 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.
