Does Bighorn Hills Estates Property Owners have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2023. The violations listed here began between October 1992 and January 2023. By type: 10 monitoring and reporting, 1 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 11 as archived 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. 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.
