Water pollution is the contamination of water by the unwanted/harmful substances.
Water in our locality can be polluted by the sewage wastes, hotel waste, excess detergents, chemicals from the factories, excess use of fertilizers and pesticides which seeps into the ground and may contaminate the ground water, etc. We can dispose natural waste materials by producing compost, vermicompost, manures, etc.
Artificial materials are mostly recyclable.So before releasing it to the water bodies we can treat them
We should try to use the resources as minimum as possible.
