Does Stout Water Supply have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2015. The violations listed here began between July 1995 and April 2015. By type: 9 monitoring and reporting and 3 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (4 of them). EPA lists 11 as resolved and 1 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.
