Nitrate-Nitrogen (Nitrate)
Probability Maps and Reports
Source Water Protection

In 1998, MDH formed a multi-agency nitrate work group to produce guidance for predictive mapping of nitrate in Minnesota groundwater. The guidance was developed for use by state, county, and local government units.

The following links provide you with the nitrate-nitrogen ranking reports currently available for Minnesota. These reports were created using the methodology in the guidance document above.
