Does Bloomington have drinking water violations?
EPA's records list 4 violations for this system; 1 is health-based, and the most recent began in October 2020. The violations listed here began between November 1996 and October 2020.

The contaminants or rules involved are Total trihalomethanes (TTHM), Haloacetic acids (HAA5), Dichloromethane and Total coliform bacteria (TCR). EPA lists 3 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. 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.
