How does Canoncito compare with other water systems in New Mexico?

By EPA's size categories, Canoncito is a small system (501 to 3,300 people). Across New Mexico, the 1,165 active systems average 1,885 people each. Nationally, the average active community water system reports serving 6,703 people, so Canoncito 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. 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 Canoncito?

EPA lists Canoncito as Native American-owned. The NN state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act.

Does Canoncito have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in September 2025. The violations listed here began between March 2025 and September 2025. By type: 5 monitoring, 3 monitoring and reporting, 2 public notice, recordkeeping or other and 2 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (7 of them). EPA lists 7 as archived, 4 as unaddressed and 1 as resolved. 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. 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.
