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. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 175 Oklahoma systems (14%) list surface water as their primary source.
Who owns and regulates Altus?
EPA lists Altus 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 Jackson County (82%) are also owned by a local government.
Does Altus have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in February 2026. The violations listed here began between October 2024 and February 2026. By type: 6 monitoring and reporting and 6 contaminant level above the legal limit. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (7 of them). EPA lists 8 as archived and 4 as resolved. 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.
