How does Vici compare with other water systems in Dewey County?
By EPA's size categories, Vici is a small system (501 to 3,300 people). Dewey County has 8 active public water systems, and Vici is the 2nd-largest of them by population served. Its population served is about twice the county average of 336 people per system, and accounts for 25% of the 2,690 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 Vici 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. 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 Vici?
EPA lists Vici 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. 6 of the 8 active systems in Dewey County (75%) are also owned by a local government.
Does Vici have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in April 2025. The violations listed here began between April 2021 and April 2025. By type: 9 monitoring and reporting, 2 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Nitrate-Nitrite (4 of them). EPA lists 7 as resolved and 5 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.
