Does Marenisco Township have drinking water violations?
EPA's records list 9 violations for this system; 5 are health-based, and the most recent began in September 2012. The violations listed here began between September 1993 and September 2012. By type: 5 contaminant level above the legal limit and 4 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 8 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.
