How does Sanders School District compare with other water systems in Apache County?
By EPA's size categories, Sanders School District is a very small system (500 people or fewer). Apache County has 47 active public water systems. Its population served is about 29% below the county average of 493 people per system, and accounts for 1.5% of the 23,153 people reported by systems filed under the county. Across Arizona, the 1,769 active systems average 4,369 people each. Nationally, the average active community water system reports serving 6,703 people, so Sanders School District 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. Arizona has 936 active community water systems, 53% 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 Sanders School District?
EPA lists Sanders School District 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. 7 of the 47 active systems in Apache County (15%) are also owned by a local government.
Does Sanders School District have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in February 2026. The violations listed here began between October 2024 and February 2026. By type: 5 public notice, recordkeeping or other, 5 monitoring and reporting, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Combined Uranium (5 of them). EPA lists 5 as unaddressed, 5 as resolved and 2 as archived. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
