Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2019. The violations listed here began between December 1983 and January 2019. By type: 10 public notice, recordkeeping or other and 2 monitoring and reporting. The contaminants or rules involved are Nitrate and Total coliform bacteria (TCR). EPA lists 10 as archived and 2 as resolved.
