Water-Pollution

Water pollution is the introduction of chemical, biological and physical matter, into large bodies of water that degrade the quality of life that lives in it, and consumes it. Wastes from domestic, industrial, and agricultural activities are major sources of water pollution.

When water loses its natural, physical properties and becomes coloured with offensive odour and bad taste, the water is said to be polluted. Pollution could be directly or indirectly discharged into water. Wastes from homes that can cause pollution are called domestic wastes, while those from industries are called industrial waste.
