 (yo͞o-trŏf′ĭk, -trō′fĭk)
Rich in mineral and organic nutrients that promote a proliferation of algae and aquatic plants, resulting in a reduction of dissolved oxygen. Used of a lake or pond.

[From Greek eutrophos, well-nourished : eu-, eu- + trephein, to nourish.]

eu·troph′i·ca′tion n.

(Environmental Science) a process by which pollution from such sources as sewage effluent or leachate from fertilized fields causes a lake, pond, or fen to become overrich in organic and mineral nutrients, so that algae and cyanobacteria grow rapidly and deplete the oxygen supply

The over-enrichment of water by nutrients (e.g. from chemical fertilizer or sewage), causing overgrowth and decay of plants, deoxygenation of water, and the death of its organisms.

Noun1.eutrophication - excessive nutrients in a lake or other body of water, usually caused by runoff of nutrients (animal waste, fertilizers, sewage) from the land, which causes a dense growth of plant life; the decomposition of the plants depletes the supply of oxygen, leading to the death of animal life; "he argued that the controlling factor in eutrophication is not nitrate but phosphate"
biological process, organic process - a process occurring in living organisms

(2007) showed that the eutrophic condition of one-third of the estuaries in the mid-Atlantic region had worsened over the 15-year survey period from 1990 to 2004, with the coastal lagoons exhibiting the most acute symptoms of eutrophication (Figure 2).
The publication describes how pellet reactor systems bring big benefits to wastewater operations by breaking the nasty cycle of phosphorous eutrophication, and closing the process loop by recovering the phosphorous as a useful by-product.
Pollution, high temperatures, eutrophication, or algae blooms could be the causes behind the death of the fish, said Christophe Tourenq, manager, science and research, Emirates Wildlife Society-WWF.
Terrestrial eutrophication (N[O.sub.x], N[H.sub.3]) can be defined as the state of increased nutrient availability in soil as a result of input of plant nutrients.
However, these mass occurrences of microscopic algae have become more frequent and intense due to the eutrophication of the Baltic Sea (HELCOM, 2003).
The country's National Institute of Livestock and Grassland Science, Tsukuba, examined CO2 emissions emitted by way of methane from beef cattle; the energy required to create the beef (including feed production, husbandry, transport, slaughtering, butchering and packaging); plus the environmental effects of production methods, for instance water acidification and eutrophication, with excessive nutrient runoff into lakes, rivers and ponds reducing oxygen content and CO2 absorption.
Increased acreage dedicated solely to intensively managed continuous corn rotation means an increase in soil erosion and local nutrient loads contributing to eutrophication of rivers, streams and lakes, reduced fish habitat, impaired drinking water and hypoxic (oxygen-depleted) zones in coastal waters.
However, reckless overconsumption, misuse, pollution, eutrophication,
The investigators observed variance in unnecessary potential air pollution and unnecessary eutrophication potential between sites.
The study, published recently in the Nature Communications journal, concluded that the greening of lakes known as 'eutrophication,' would cause methane emissions to increase in the atmosphere by 30% to 90% over the next 100 years.
