What does “community water system” mean?

A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. South Dakota has 510 active community water systems, 73% of the state's 699 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 100 South Dakota systems (14%) list purchased groundwater as their primary source.

Who owns and regulates Wakonda?

Does Wakonda have drinking water violations?

EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in January 2022. The violations listed here began between July 1976 and January 2022. By type: 4 monitoring and reporting, 3 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Stage 1 Disinfectants and Disinfection Byproducts Rule (2 of them). EPA lists 6 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. 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.
