How does Glendale Colony compare with other water systems in Spink County?
By EPA's size categories, Glendale Colony is a very small system (500 people or fewer). Spink County has 10 active public water systems. Its population served is well below the county average of 349 people per system, and accounts for 2.7% of the 3,485 people reported by systems filed under the county. Across South Dakota, the 699 active systems average 1,387 people each. Nationally, the average active community water system reports serving 6,703 people, so Glendale Colony is well below that figure.
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. 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 Glendale Colony?
EPA lists Glendale Colony as privately owned. 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. 3 of the 10 active systems in Spink County (30%) are also privately owned.
Does Glendale Colony have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in November 2025. The violations listed here began between January 2012 and November 2025. By type: 10 monitoring and reporting, 1 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (2 of them). EPA lists 11 as resolved and 1 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.
