- The pollution level of the Ganges always spikes during the pilgrimage season in May and June, when thousands of people flock. Pilgrims use Ganges water to drink or bathe, with the belief that the sacred flow will wash away all sins. 

Hydroelectric:

- The hydroelectric potential of the Ganges and its tributaries is enormous—estimates have ranged from some 51,700 to 128,700 megawatts.
