Speech on Water Pollution: Sources, Effects and Control of Water Pollution!
Water pollution is the result of economic growth. The main sources of water pollution are flushing waste down the domestic sewage, industrial effluents containing organic pollutants, and wastes of chemicals, heavy metals and mining activities.
The major water polluting industries are refineries, fertilizers, pesticides, chemicals, leather, pulp and paper, and metal plating. Sewage waste and industrial effluents flow into lakes, canals, rivers, coastal areas and underground water sources.
Sources of Water Pollution:
The following are the sources of water pollution:
1. Domestic Sewage:
The domestic sewage includes household wastes which pass through municipal sewerage system. It includes food wastes, modern synthetic detergents used for washing clothes, cleaning bathrooms and latrines.
2. Industrial Effluents:
Industries produce chemicals that contaminate water sources, when industrial wastes are discharged in the nearby rivers or streams through flush lanes of factories. The textile, sugar and fertilizer factories, oil refineries, synthetic plants for manufacturing of drugs, rubber, plastic and rayon fibres, paper industries and chemical factories all produce chemical pollution.
3. Agricultural Sources:
Modern agricultural techniques require the use of fertilizers to improve the fertility of land and increase production. Excess of nitrates used as fertilizers seep into ground water and are further carried into ponds or lakes. On entering the drinking water, these produce several health hazards.
4. Household Waste:
With the increase in population, the consumption of soaps and detergents also increases which pollute the water. Moreover, rubber, plastics and polythene drain into waterholes and pollute them during rainfall.
