What does “transient non-community water system” mean?

Michigan has 7,865 active transient non-community water systems, 74% of the state's 10,599 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 10,214 Michigan systems (96%) list groundwater as their primary source.

Who owns and regulates The Post?

Does The Post have drinking water violations?

EPA's records list 11 violations for this system; none is health-based, and the most recent began in July 2024. The violations listed here began between July 1996 and July 2024. By type: 6 monitoring and reporting and 5 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 10 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.
