Does Town of Dlo have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in September 2015. The violations listed here began between January 2014 and September 2015. By type: 12 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 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. 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.
