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 Kalkaska Screw Products have drinking water violations?
EPA's records list 11 violations for this system; none is health-based, and the most recent began in February 2019. The violations listed here began between January 2006 and February 2019. By type: 6 monitoring and 5 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 9 as resolved and 2 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.
