Nitrate-Nitrogen (Nitrate) Probability Mapping
Source Water Protection

The MDH developed nitrate-nitrogen (nitrate) probability maps to assist in state and local water quality planning efforts. These maps rank areas with relatively high, moderate, and low risk of elevated nitrate concentrations in the water table aquifer. The goal of the map is to help protect public and private drinking water supplies and prevent contamination.
