Almost one million Minnesotans use private wells to obtain water for their homes.
Clean and safe drinking water is an important part of a healthy environment and our health. Although public water supplies that come from groundwater (for cities, institutions and restaurants, for example) are monitored and must meet health standards, private wells are not routinely monitored by government agencies. Well water users should consider periodic testing of their supplies.
The Minnesota Department of Health says there are health risks from contaminants in well water, such as bacteria, nitrate, arsenic, and other chemicals.
