 (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.]

(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
