EPA lists Canaan Middle School as privately owned. The OH state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 46 of the 53 active systems in Madison County (87%) are also privately owned.
Does Canaan Middle School have drinking water violations?
EPA's records list 9 violations for this system; 4 are health-based, and the most recent began in July 2022. The violations listed here began between July 1995 and July 2022. By type: 4 contaminant level above the legal limit, 2 monitoring, 2 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Arsenic (4 of them). EPA lists 7 as resolved, 1 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
