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. New Mexico has 151 active non-transient non-community water systems, 13% of the state's 1,165 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 37 New Mexico systems (3.2%) list surface water as their primary source.
Who owns and regulates Enterprise Products Company Chaco Plant?
EPA lists Enterprise Products Company Chaco Plant as privately owned. The NM state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 6 of the 22 active systems in San Juan County (27%) are also privately owned.
Does Enterprise Products Company Chaco Plant have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in October 2025. The violations listed here began between March 1995 and October 2025. By type: 9 monitoring and reporting and 3 required treatment not met. The contaminant or rule involved most often is Surface Water Treatment Rule (5 of them). EPA lists 8 as resolved and 4 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.
