Does Ponderosa Park Water System have drinking water violations?
EPA's records list 7 violations for this system; 3 are health-based, and the most recent began in October 2004. The violations listed here began between October 1991 and October 2004. By type: 4 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them).
