How does Arcadia Public Works Authority compare with other water systems in Oklahoma County?
By EPA's size categories, Arcadia Public Works Authority is a very small system (500 people or fewer). Oklahoma County has 113 active public water systems.

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 groundwater under the influence of surface water means the system buys that kind of water from another public water system. 5 Oklahoma systems (0.4%) list purchased groundwater under influence as their primary source.
Who owns and regulates Arcadia Public Works Authority?

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. 19 of the 113 active systems in Oklahoma County (17%) are also owned by a local government.
Does Arcadia Public Works Authority have drinking water violations?
EPA's records list 11 violations for this system; 3 are health-based, and the most recent began in October 2025. The violations listed here began between October 2022 and October 2025. By type: 8 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (6 of them). EPA lists 7 as resolved and 4 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.
