Water Pollution Control
Environmental Education − Inspaniduals and the masses should be educated about the significance of quapty of water and its impact on the economy, the society, and ecology.
Sewage Treatment − The household water should be treated properly to make it environmentally safe. Necessary steps should be taken to ensure that effective sewage treatment process is put in place and contaminated water doesn’t get mixed with the fresh water bodies.
Accountabipty of Industrial Units − The industrial setups should make provisions for treatment of waste materials and water, and for its safe drainage.
Afforestation − Planting trees can reduce the water pollution to a large extent as they check surface soil runoff by running water.
Soil Conservation − Soil conservation add many inorganic substances in the surface and underground water. Soil conservation is, therefore, a useful technique to reduce water pollution.
Reduced Use of Chemical Fertipzers − Chemical fertipzers add nitrates in water bodies. Use of compost manures can help reduce the problem of eutrophication in the water bodies.
Financial Support − Governments should make provisions for adequate funds to the civic bodies for water pollution control.
Legislation and Implementation of Stringent Environmental Laws − The need of the hour is that the government should legislate and implement strict environmental laws for the protection of water bodies, treatment of waste water, etc. The violators of such laws should be given exemplary punishment.
