Nebraska 23 Natural Resources Districts (NRDs) utilize trigger points signifying specific levels of nitrate in groundwater through monitoring well testing.<\/span><\/p>

These triggers are put in place to protect the drinking water supply. Trigger points may vary within the individual NRD boundary, but are relative to the safe drinking water standards mandated federally.<\/span><\/p>

A District may have all, none, or part of its districts designated as Phase 1, II, III and IV areas, or any combination. The higher the Phase, the more implementation of management efforts for protection is required. It is best to consult with your local NRD to identify with their programs.
