The pollution of river water is caused by the duping of untreated sewage and industrial wastes into it.
Detection of Pollutants in River
The contamination of river water can be usually found from two factors:
Wells and tube-wells (bore-wells) are yet another source of water. Some of the rainwater which falls on earth seeps through the soil and goes down under the surface of the earth. Ultimately this water is stopped by some hard rocks and collects there. This underground water is taken out by digging a ‘well’ into the ground.
Steps taken by the government against river pollution: GANGA ACTION PLAN of 1985
It is the project to clean the Ganga River. It aims to install sewage treatment plants for 27 cities at the bank of the river to handle millions of litres of sewage daily before its discharge into the river. Main pollutants are coliform group of bacteria.
Watershed management emphasises scientific soil and water conservation in order to increase the biomass production.
