How does Douglas compare with other water systems in Garfield County?
By EPA's size categories, Douglas is a very small system (500 people or fewer). Garfield County has 22 active public water systems. Its population served is well below the county average of 2,831 people per system, and accounts for less than 0.1% of the 62,290 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 Douglas 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 groundwater means the system buys groundwater from another public water system rather than drawing its own. 67 Oklahoma systems (5.3%) list purchased groundwater as their primary source.
Who owns and regulates Douglas?
EPA lists Douglas 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. 19 of the 22 active systems in Garfield County (86%) are also owned by a local government.
Does Douglas have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2025. The violations listed here began between July 2009 and October 2025. By type: 6 public notice, recordkeeping or other, 5 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Consumer Confidence Rule (6 of them). EPA lists 9 as resolved, 2 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
