  • Note that water test results are usually presented in milligrams per liter (mg/l) or micrograms per liter (µg/l) for example, a water test might indicate that the water contains 6 mg/l nitrate, meaning that a liter of water contains an average concentration of 6 milligrams of nitrate note also that one mg/l is equivalent to one part per million.
  • Increasing nitrate levels in surface and ground waters are a potential source of severe environmental stress to aquatic organisms because nitrate is known to be toxic to crustaceans (muir et al, 1990), insects (camargo and ward, 1992), amphibians (baker and waights, 1993, 1994), and fish (westin, 1974 rubin and elmaraghy, 1977.
