Regionally, nitrate nitrogen concentrations are continuing to increase in both surface water and ground water based on monitoring data. The increasing trends are thought to be attributable to over application of manure and commercial nutrients on row-cropped fields. In order for nitrate concentrations to decrease, nutrient management is needed throughout the basin. Two nutrient management specialists will assist landowners in the eleven-county Southeast Minnesota Area with writing nutrient management plans and implementing conservation practices for manure and fertilizer use.
The lack of sewage treatment in some small communities in Southeast Minnesota is causing surface water and groundwater pollution. Fourteen of these communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes discharging raw sewage directly into the environment;surfacing sewage or have sewage contaminating groundwater.
