Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2017. The violations listed here began between April 2008 and December 2017. By type: 9 monitoring and reporting, 2 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Consumer Confidence Rule (2 of them).
