South Dakota has 173 active transient non-community water systems, 25% of the state's 699 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 431 South Dakota systems (62%) list groundwater as their primary source.
Who owns and regulates Schmidt'S Landing?

Does Schmidt'S Landing have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in June 2024. The violations listed here began between October 1993 and June 2024. By type: 5 public notice, recordkeeping or other, 4 monitoring and reporting, 2 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 7 as archived and 5 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.
