Big Sioux Water Quality Impact Study


The Big Sioux Water Quality Impact Study will determine the impact of water quality changes in the Big Sioux River on public water supply wellfields in the Big Sioux aquifer. The objectives of this study are to:

Tasks in progress include installing observation wells between the river and the wellfields, conducting aquifer tests, determining water quality patterns in the aquifer, and building ground water models to simulate the Big Sioux aquifer under different conditions.

Ground water models being developed.
