Does Whiteside Homeowners Association have drinking water violations?
EPA's records list 11 violations for this system; 6 are health-based, and the most recent began in January 2009. The violations listed here began between September 1994 and January 2009. By type: 6 contaminant level above the legal limit and 5 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 8 as archived and 3 as resolved.
