How does Zia Pueblo compare with other water systems in New Mexico?

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. New Mexico has 645 active community water systems, 55% of the state's 1,165 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,009 New Mexico systems (87%) list groundwater as their primary source.

Who owns and regulates Zia Pueblo?

EPA lists Zia Pueblo as Native American-owned. The EPA Region 06 is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act.

Does Zia Pueblo have drinking water violations?

Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in April 2025. The violations listed here began between October 2010 and April 2025. By type: 5 contaminant level above the legal limit, 4 monitoring and reporting, 2 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 11 as resolved 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. 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.
