Does Corydon Water Works have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2000. The violations listed here began between October 1979 and October 2000. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Selenium (2 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.
