What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live.

Michigan has 1,402 active non-transient non-community water systems, 13% 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 Mdot - Regional Office?
EPA lists Mdot - Regional Office as owned by a state government. The MI state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 10 of the 218 active systems in Jackson County (4.6%) are also owned by a state government.
Does Mdot - Regional Office have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2025. The violations listed here began between January 1999 and January 2025. By type: 11 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Revised Total Coliform Rule, Cadmium, Cyanide and Antimony. 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.
