Nitrates and Nitrites in Water

• Description:
  Nitrogen, an essential nutrient, is absorbed and incorporated by plants from nitrate or ammonium in soil. The use of nitrogen fertilizer for improved crop yields has generally increased in the United States and globally since the 1950s, peaking in the United States around 1990. Nitrate contamination of water supplies is a potential environmental consequence of modern agricultural activity and increasing urbanization. Nitrate concentrations in shallow groundwater and some surface waters have increased as a result of use of nitrogen fertilizers, intensive livestock operations that produce large amounts of animal waste, substandard private septic systems, and municipal wastewater treatment discharges. A recent US Geological Survey National Water Quality Assessment Program report documents elevated nitrate concentrations in 4 of 33 major aquifers sampled in rural and urban areas. Poorly constructed shallow wells in rural areas are at greatest risk of nitrate contamination. In general, nitrite is not as prevalent in water supplies as nitrate, because nitrite is rapidly converted to nitrate, depending on aerobic and bacterial conditions. [Description provided by NIOSH]
