Does Town of Two Buttes have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in January 2026. The violations listed here began between May 2024 and January 2026. By type: 5 contaminant level above the legal limit, 3 monitoring and reporting, 2 monitoring, 1 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Combined Radium (-226 and -228) (6 of them). EPA lists 7 as resolved and 5 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.
