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 Commerce?
EPA lists Commerce 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. 15 of the 19 active systems in Ottawa County (79%) are also owned by a local government.
Does Commerce have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2025. The violations listed here began between January 2023 and January 2025. By type: 10 monitoring and reporting, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Lead and Copper Rule Revisions (2 of them). EPA lists 10 as archived and 2 as addressed.
