Does Colorado Ntnl Monument Lat 2 have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2025. The violations listed here began between April 2017 and October 2025. By type: 7 monitoring and reporting, 3 monitoring and 2 reporting. The contaminant or rule involved most often is Surface Water Treatment Rule (7 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.
