Does North Andover Water Dept have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in August 2015. The violations listed here began between April 1991 and August 2015.

The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 7 as archived and 5 as resolved.
