How does University Estates compare with other water systems in Brookings County?
By EPA's size categories, University Estates is a very small system (500 people or fewer). Brookings County has 12 active public water systems. Its population served is well below the county average of 3,439 people per system, and accounts for 0.4% of the 41,264 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 University Estates 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. 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 University Estates?
EPA lists University Estates 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. 7 of the 12 active systems in Brookings County (58%) are also privately owned.
Does University Estates have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in December 2023. The violations listed here began between October 1996 and December 2023. By type: 5 monitoring and reporting, 4 public notice, recordkeeping or other, 2 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 6 as resolved and 6 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.
