How does Bonita Public School compare with other water systems in Graham County?
By EPA's size categories, Bonita Public School is a very small system (500 people or fewer). Graham County has 16 active public water systems. Its population served is well below the county average of 1,859 people per system, and accounts for 0.4% of the 29,739 people reported by systems filed under the county. Across Arizona, the 1,769 active systems average 4,369 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Bonita Public School is well below that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Arizona has 232 active non-transient non-community water systems, 13% of the state's 1,769 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,612 Arizona systems (91%) list groundwater as their primary source.
Who owns and regulates Bonita Public School?
EPA lists Bonita Public School as owned by a local government. The AZ state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 2 of the 16 active systems in Graham County (13%) are also owned by a local government.
Does Bonita Public School have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in March 2026. The violations listed here began between September 2025 and March 2026. By type: 6 monitoring and reporting, 5 monitoring and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 9 as archived, 2 as resolved and 1 as unaddressed. 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. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
