The main causes of eutrophication are an increase in the concentration of nutrients in an ecosystem. Nutrient pollution released to coastal areas comes from many diverse sources including agriculture, aquaculture, septic tanks, urban wastewater, urban stormwater runoff, industry, and fossil fuel combustion. Nutrients enter aquatic ecosystems via the air, surface water, or groundwater.
