EPA's records list 11 violations for this system; 2 are health-based, and the most recent began in September 2019. The violations listed here began between April 1994 and September 2019. By type: 8 monitoring and reporting, 2 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them).
