Does City of Hankinson have drinking water violations?
EPA's records list 11 violations for this system; 6 are health-based, and the most recent began in January 2004. The violations listed here began between February 1991 and January 2004. By type: 5 monitoring and reporting, 5 contaminant level above the legal limit and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 of them). EPA lists 9 as archived and 2 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
