Nitrate is a common contaminant in groundwater. Groundwater with excessive nitrate contamination can have immediate and long-term health effects. This publication addresses the drinking water nitrate standard, water testing, nitrate sources, reducing nitrate contamination risk, and groundwater treatment methods.
Water supply to rural residences and agricultural operations without rural or public water systems is usually obtained from a private well or surface water supply. Information about constructing a well in a safe location and maintenance guidelines for existing wells can be found in two recently updated publications from K-State Research and Extension.
