[David K Mueller; Dennis R Helsel; Mary A Kidd; Geological Survey (U.S.); National Water-Quality Assessment Program (U.S.)] -- Nutrients in water are necessary for productive aquatic ecosystems, but in high concentrations, nutrients such as nitrates, ammonia, and phosphates can adversely affect aquatic life and human health.
Nutrients include nitrates found in sewage and fertilizers and phosphates found in detergents and fertilizers. In excess levels, nutrients overstimulate the growth of aquatic plants and algae.
Excessive growth of these organisms, in turn, can clog navigable waters, use up dissolved oxygen as they decompose, and block light to deeper waters. This. Sources of Nutrients in the Nation’s Watersheds By Richard A.
