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.

Does Manthei Construction have drinking water violations?
EPA's records list 4 violations for this system; none is health-based, and the most recent began in September 2024. The violations listed here began between January 2024 and September 2024. By type: 3 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Lead and Copper Rule, Revised Total Coliform Rule, Nitrate and Arsenic. EPA lists 2 as archived, 1 as unaddressed and 1 as resolved.

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.
