Answer:
Water pollution is the contamination of water bodies, usually as a result of human activities, in such a manner that negatively affects its legitimate uses. Water pollution reduces the ability of the body of water to provide the ecosystem services that it would otherwise provide. Water bodies include for example lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants are introduced into these water bodies. In addition to damage to many species, water pollution can also lead to water-borne diseases for people.
Causes : Sewage: Emptying the drains and sewers in fresh water bodies causes water pollution. The problem is severe in cities.
Industrial Effluents: Industrial wastes containing toxic chemicals, acids, alkalis, metallic salts, phenols, cyanides, ammonia, radioactive substances, etc., are sources of water pollution.They also cause thermal (heat) pollution of water.
Synthetic Detergents: Synthetic detergents used in washing and cleaning produce foam and pollute water.
Agrochemicals: Agrochemicals like fertilizers (containing nitrates and phosphates) and pesticides (insecticides, fungicides, herbicides etc.) washed by rain-water and surface runoff pollute water. ADVERTISEMENTS:
Oil: Oil spillage into sea-water during drilling and shipment pollute it.
