Does City of Milton have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in November 2020. The violations listed here began between April 2009 and November 2020. By type: 9 monitoring and reporting and 3 monitoring. The contaminant or rule involved most often is Chlorine (5 of them). EPA lists 11 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.
