Does Echo Road Group Water Assoc have drinking water violations?
EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in September 2020. The violations listed here began between October 1982 and September 2020. By type: 4 public notice, recordkeeping or other, 2 contaminant level above the legal limit, 1 required treatment not met and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 5 as archived and 3 as resolved.
