Quality Assessment: Chemical: Nitrates, Nitrites, and Ammonia
Although nitrogen is an essential nutrient for all aquatic plants and animals, it is possible to have too much of a good thing. Excessive concentrations of nitrogen can lead to eutrophication and subsequent degradation of stream water quality. In addition, if water containing nitrate levels greater than 10 mg NO3-N/L is used to prepare infant formula, it can result in methemoglobinemia. Methemoglobinemia is a condition in which red blood cells are prevented from transporting oxygen throughout the body. If the condition persists, the infant can suffocate.
