How does Shungopavi compare with other water systems in Arizona?
By EPA's size categories, Shungopavi is a small system (501 to 3,300 people). 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 Shungopavi 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. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 71 Arizona systems (4%) list purchased groundwater as their primary source.
Who owns and regulates Shungopavi?
EPA lists Shungopavi as Native American-owned. The EPA Region 09 is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act.
Does Shungopavi have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in August 2025. The violations listed here began between January 2023 and August 2025. By type: 4 contaminant level above the legal limit, 3 monitoring and reporting, 2 monitoring, 1 public notice, recordkeeping or other, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Arsenic (5 of them). EPA lists 9 as resolved, 2 as unaddressed and 1 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
