Does LDS Church Island Park have drinking water violations?

EPA's records list 7 violations for this system; 4 are health-based, and the most recent began in May 2021. The violations listed here began between April 1997 and May 2021. By type: 4 contaminant level above the legal limit and 3 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them).
