Nitrate and phosphate pollution in water bodies has an overall deleterious effect on water bodies.
Nitrates and phosphates are inorganic compounds. Many detergents are composed of phosphates which commonly serves as a cleaning agent. Also, farmlands are important sources of nitrate and phosphates
Untreated sewage and surface runoff often find their way into water bodies. When this happens, the nitrates and phosphates present from these sources cause rapid growth of algae. This is called eutrophication.
Rapid death of these algae increases the organic load of water and largely decreases the oxygen content of water leading to the appearance of a dead lake.
Hence nitrate and phosphate pollution in water bodies has an overall deleterious effect on water bodies.
