Groundwater is Nebraska's most important natural resource. The principal source of groundwater in Nebraska is the High Plains Aquifer System. This system underlies approximately 85 percent of the state and supplies 95 percent of all groundwater used in Nebraska. The majority of groundwater in Nebraska is used by agriculture but domestic and commercial uses are also important. Eighty-two percent of Nebraskans use groundwater as their major source of drinking water, and nearly all of the state's farm homes rely on groundwater for their domestic needs.

Application of agricultural chemicals has come under increased scrutiny from environmental groups and federal regulatory agencies. Nitrogen fertilizer is used in greater quantities than any other agricultural chemical. It also is the contaminant most often found in Nebraska groundwater. Accurate application of nitrogen is important from an environmental and economic viewpoint. Approximately 800 million pounds of nitrogen are applied to 12 million acres of Nebraska cropland each year. Nitrogen applied as anhydrous ammonia (NH3) accounts for around 40 percent of the total nitrogen applied.
