Minnesota has 5,008 active transient non-community water systems, 77% of the state's 6,465 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,261 Minnesota systems (97%) list groundwater as their primary source.

Who owns and regulates Tamarack Resort?

Does Tamarack Resort have drinking water violations?

EPA's records list 11 violations for this system; 8 are health-based, and the most recent began in May 2013. The violations listed here began between May 1996 and May 2013. By type: 7 required treatment not met, 3 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Surface Water Treatment Rule (8 of them). EPA lists 8 as archived and 3 as resolved. 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. 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.
