Question
Name any three water pollutants.

Answer

Three water pollutants are:
  1. Waste from farms i.e. fertilizers and pesticides. The chemicals in them pollute the water.
  2. Industries release their waste products directly into the rivers thus degrading water quality.
  3. Disease causing agents like bacteria, viruses and protozoans enter the sewage system. This sewage is ultimately discharged into water bodies like sea.
