context_page_description: Eutrophication, distrophication or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae. This process may result in oxygen depletion of the water body. One example is an "algal bloom" or great increase of phytoplankton in a sandy body as a response to increased levels of nutrients. Eutrophication is often induced by the discharge of nitrate or phosphate-containing detergents, fertilizers, or sewage into an aquatic system. Lake eutrophication has become a global problem of water pollution, Chlorophyll-a, total nitrogen, total phosphorus, chemical oxygen demand and secchi depth are the main indicators to evaluate lake eutrophication level.
