Question

why did ganga water be as it is after 10 years also?

Answer 1

Hey there!

The Ganga, is a trans,-boundry river of Asia which flows through the nations of India and Bangladesh. 

Pollution of the Ganges (or Ganga), the largest river in India, poses significant threats to human health and the larger environment. 
Severely polluted with human waste and industrial contaminants, the river provides water to about 40% of India's population across 11 states, serving an estimated population of 500 million people or more, more than any other river in the world.

Today, Ganges is considered to be the fifth most polluted river in the world.
It's pollution level is so high that, It is impossible to re-new Ganga after 10 years also.


Hope it helped
