Does Bill Cody Ranch have drinking water violations?

Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in May 2021. The violations listed here began between October 1994 and May 2021. By type: 8 monitoring and reporting, 2 monitoring and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 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. 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.
