A:

Dear Snehal.

Major sources of river pollution are:

  1. Discharge of effluents or liquid wastes from industries.
  2. Dumping of household and municipal wastes into the rivers.
  3. Use of excessive pesticides and insecticides in agricultural fields. This wastes can reach river due to surface runoff water.
