When toxic substances enter lakes, streams, rivers, oceans, and other water bodies, This results in the pollution of water
Water pollution has many sources. The most polluting of them are the city sewage and industrial waste discharged into the rivers.
Agricultural run-off, or the water from the fields that drains into rivers, is another major water pollutant as it contains fertilizers and pesticides.
Domestic sewage waste water that is discarded from households called sanitary sewage, such water is impure
The main organic materials are food and vegetable waste, plant nutrient come from chemical soaps, washing powders, etc. Domestic sewage is also very likely to contain disease-causing microbes. Thus, disposal of domestic waste water is a significant technical problem.
Today, many people dump their garbage into streams, lakes, rivers, and seas,
Today cleaning products are synthetic detergents and come from the petrochemical industry. Most detergents and washing powders contain phosphates, which are used to soften the water among other things. These and other chemicals contained in washing powders affect the health of all forms of life in the water.
Agricultural Run off
The high nitrate content in groundwater is mainly from irrigation run-off from agricultural fields where chemical fertilizers have been used indiscriminately.
Industrial effluents
During the last fifty years, the number of industries in India has grown rapidly.
Waste water from manufacturing or chemical processes in industries contributes to water pollution.
Most major industries have treatment facilities for industrial effluents. But this is not the case with small-scale industries, which cannot afford enormous investments in pollution control equipment as their profit margin is very slender.
Effects of water pollution
The effects of water pollution are not only devastating to people but also to animals, fish, and birds. Polluted water is
