How does Jet compare with other water systems in Alfalfa County?
By EPA's size categories, Jet is a very small system (500 people or fewer). Alfalfa County has 11 active public water systems. Its population served is about 44% below the county average of 409 people per system, and accounts for 5.1% of the 4,497 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 Jet 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 Jet?
EPA lists Jet 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 Alfalfa County (82%) are also owned by a local government.
Does Jet 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 2026. The violations listed here began between August 2013 and January 2026. By type: 9 monitoring and reporting, 1 monitoring, 1 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Lead and Copper Rule (4 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.
