Does Mels Diner have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2016. The violations listed here began between July 1994 and April 2016. By type: 11 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (11 of them). EPA lists 9 as archived and 3 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. 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.
