Excerpt from Economic Effects of Controls on Nitrogen Fertilizer

Researchers are still uncertain about the possible link between human health hazards and the use of commercial nitrogen fertilizers and other sources that raise the nitrate content of water. In some areas of the United States the nitrate concentration in water, expressed as nitrate nitrogen, chronically exceeds the standard of 10 parts per million, in some cases up to ten times this level, yet no serious health problems have been linked to nitrates in these areas. Even so, the possibility that hazards may develop warrants an investigation of the economic effects of various control measures.
