Nitrate-Nitrogen (Nitrate)
Source Water Protection

Nitrate-Nitrogen (Nitrate) commonly occurs in groundwater and is important in Source Water Protection for several reasons:

  • nitrate can be linked to activities at the ground surface;
  • nitrate is commonly present when other contaminants are also present (indicator analyte); and
  • nitrate is inexpensive to measure.

For these reasons, the Source Water Protection program emphasizes efforts to understand and limit nitrate occurrence in groundwater. These efforts yield the following resources:
