Drinking Water Issues

Nitrogen is a nutrient that can move from agricultural fields into surface or ground water. At high concentrations in drinking water, nitrate-nitrogen causes health problem for babies. Public drinking water suppliers must address such concerns when water sources exceed the drinking water standard of 10 parts per million.

Although drinking water contamination by agricultural pesticides may be a less frequent problem, similarly if water contains pesticides in concentrations above safe drinking water standards there are potenial health consequeces that require action by public water suppliers. Three parts per billion is the standard for atrazine, a pesticide commonly used in the Heartland states.
