Nitrates leached into groundwater may be associated with the following: (1) methemoglobinemia (blue baby) in humans and other mammals; (2)cardiovascular collapse and shock in horses; (3) possibility of cancer (EPA); and (4) eutrophication of water bodies (IFIA) when nitrate contaminated groundwater reaches surface water through wells or springs. Nitrate leaching is not only a possible source of environmental damage but also the loss of an input before it is used in production.

Nitrate nitrogen (N03-N) leaching is becoming an alarming threat to ground water in many areas in the U.S. In one study in North Carolina, over 9000 domestic wells were sampled for nitrate. Over 3 percent (288 wells) contained N03-N at levels exceeding the Environmental Protection Agency (EPA) safe drinking water standard of 10 mgIL (Jennings, et aI., 1991). Ground water quality concerns in central Nebraska surfaced in the mid 1950s when scientists observed increasing N03-N concentrations in the ground water of some river valleys (Olson et aI., 1962). In Utah also, excessive N03-N contamination has been found in private wells. …

Pesticides reduce crop losses due to insects, pathogens, weeds and other pests, but can contaminate ground water. Ground water refers to water in the saturated portion of the soil material. Water in an unsaturated region of the soil is termed soil moisture.

Production of adequate supplies of food and fiber currently requires that pesticides be used to limit crop losses from insects, pathogens, weeds and other pests. The term pesticide refers to a large number ofchemical compounds. Pesticides include acaricides, fungicides, herbicides, insecticides, nematicides, algicides, arboricides, zoocides, and many more.

Groundwater is a hidden, but important resource. We can practicably define groundwater as water be· neath the ground surface that can be extracted by wells. Other water in the ground that is not considered to be available for man's direct use is commonly called "subsurface water." Subsurface water includes moisture within the root zone.
