Consider the following explanation:


  1. Industries discharge chemical wastes comprising substances called effluents in rivers, lakes, streams etc.
  2. Factories sometimes turn waterways into open sewers by dumping oil, toxic chemicals and other harmful liquids called effluents into them
  3. These chemicals not only pollute the water reservoirs but also disturb the natural purification cycle of water carried out by microorganisms.
  4. Waste from tanneries and other heavy industrial plants contain heavy elements such as Chromium, Lead, Mercury etc which pose severe threats to the aquatic life.
  5. Moreover, the fertilizer industries dump nitrogenous and phosphate-containing waste into the rivers, lakes and other reservoirs causing Eutrophication.
