Water is vital, renewable resource, and crucial for supporting all life forms. Water quality is important concerning both environmental and economic aspects. Rapid urbanization, industrialization, agriculture practices increase the water pollution. Water pollution refers to the changes in any water body’s chemical, physical, and biological condition owing to the input, substitution, or removal of organic, inorganic, biological, or radioactive substances, etc. Point source includes industrial and municipal wastewater in which pollutant travels directly from source to water; while non-point source includes urban and agricultural run-off which make their way into the aquatic ecosystems. Various types of industrial wastewater include suspended solids, chemicals, and toxic compounds, metals, non-metals, organic, inorganic pollutants, solvents, and solid–liquid waste. While the composi­tion of municipal wastewater varies, but chiefly comprises substances like food mat­ter, beverages, inorganic and organic solids, and pharmaceutical wastes, etc. There are wastewater-related challenges and issues both in developed and developing countries. While major problems are being faced by developing countries like lack of access to clean water, sanitation, effective wastewater management causing mul­tiple diseases across the population, besides, the lack of sufficient funds. Humans face health problems that are associated with water-related infectious diseases like diarrhoea, hepatitis, cholera, dysentery, dermatophytosis, malaria, yellow fever, dengue fever, filariasis, and other disorders. Pollution prevention is the key that reduces the load of pollutants discharged into the water bodies. Pollution control strategies seek the management of pollutants by stern actions, legislation and regu­lations, public awareness for sustainable use of resources, and recycling and treat­ment of industrial and municipal wastewater.
