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

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.

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.
