Does Hill & Dell #1 have drinking water violations?
EPA's records list 5 violations for this system; 2 are health-based, and the most recent began in January 2007. The violations listed here began between October 1991 and January 2007. By type: 3 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 3 as archived and 2 as resolved.
