How does Eden compare with other water systems in Marshall County?
By EPA's size categories, Eden is a very small system (500 people or fewer). Marshall County has 7 active public water systems, and Eden is the 5th-largest of them by population served. Its population served is well below the county average of 305 people per system, and accounts for 4.4% of the 2,134 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 Eden 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 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 Eden?
EPA lists Eden as owned by a local government. 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. 5 of the 7 active systems in Marshall County (71%) are also owned by a local government.
