How does Spring Lake Colony compare with other water systems in Kingsbury County?
By EPA's size categories, Spring Lake Colony is a very small system (500 people or fewer). Kingsbury County has 7 active public water systems, and Spring Lake Colony is the 6th-largest of them by population served. Its population served is well below the county average of 827 people per system, and accounts for 2% of the 5,786 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 Spring Lake 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 Spring Lake Colony?
EPA lists Spring Lake 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. 2 of the 7 active systems in Kingsbury County (29%) are also privately owned.
Does Spring Lake 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 January 2020. The violations listed here began between October 2000 and January 2020. By type: 6 public notice, recordkeeping or other, 5 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 7 as resolved and 5 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.
