Does Tamworth Water Works have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in March 2009. The violations listed here began between July 1994 and March 2009. By type: 9 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them).
