Does Little Bull Falls Tavern have drinking water violations?
EPA's records list 10 violations for this system; 3 are health-based, and the most recent began in February 2008. The violations listed here began between January 1995 and February 2008. By type: 5 monitoring and reporting, 3 contaminant level above the legal limit and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 7 as resolved and 3 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.
