Drinking Water Studies
Dakota County has conducted some of the most thorough local research on private well water quality in the state. Soils and geology make much of Dakota County highly vulnerable to groundwater contamination. Public water suppliers provide their customers with water that meets health standards, but the county's groundwater poses health risks that water suppliers and private well owners must both address.
The county has done this research in order to understand the issues and trends in its groundwater quality, inform private well owners of potential risks and remedies, and develop strategies to address contamination, where possible.
