Question

Define water pollution.

Answer 1

Water pollution is defined as the alteration in the physical, chemical, or biological characteristics of water, making it unsuitable for its designated use in its natural state. According to the World Health Organisation (WHO), water pollution refers to the presence of any foreign material, either from natural or human-made sources, that contaminates the water supply and makes it harmful to life. This pollution can lead to reduced oxygen levels in water, cause aesthetically unpleasant effects, and spread epidemic diseases.
