Explanation:
Water is one of the basic necessities of life. It is an inexhaustible natural resource which is liquid between 0ºC and 100ºC. We need water for various activities such as drinking, cooking of food, bathing and washing. It is also needed for the irrigation of crops in agriculture, as an essential requirement in industries, and for navigation.
An undesirable change in the physical, biological or chemical qualities of water (due to the addition of foreign organic, inorganic, biological or radioactive substances) that adversely affects the aquatic life, and makes the water less fit or unfit for use, is called water pollution.
Agents or substances that pollute the water are called water pollutants. These can be classified into three categories.
Physical pollutants: These include heat and oil spills.
Chemical pollutants: These include organic wastes, detergents, pesticides (e.g. DDT, BHC). polychlorinated biphenyls (PCBs), inorganic chemicals (e.g., arsenic, cadmium mercury, lead, nickel, phosphates, nitrates, fluorides), and radioactive wastes. Common inorganic impurities in water are compounds of calcium and magnesium.
Biological pollutants: These include pathogens such as viruses, bacteria, protozoa, helminthes, algae, fungi, etc.
