- Nutrient pollution
Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrient. It is a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. Sources of nutrient pollution include runoff from farm fields and pastures, discharges from septic tanks and feedlots, and emissions from combustion.
