What does “community water system” mean?

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 surface water means the system buys surface water from another public water system rather than drawing its own. 142 South Dakota systems (20%) list purchased surface water as their primary source.
Who owns and regulates Alexandria?

The SD state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 2 of the 3 active systems in Hanson County (67%) are also owned by a local government.
Does Alexandria have drinking water violations?
EPA's records list 7 violations for this system; 3 are health-based, and the most recent began in May 2024. The violations listed here began between July 1976 and May 2024. By type: 4 monitoring and reporting and 3 required treatment not met. The contaminant or rule involved most often is Stage 1 Disinfectants and Disinfection Byproducts Rule (3 of them). EPA lists 4 as resolved and 3 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.
