New study reveals that Ganga river's underwater has got fragmented

According to a team of scientists from Banaras Hindu University and Mahatma Gandhi Kashividyapith University in Varanasi, it has been revealed that millions of litres of wastewater dumped in Ganga river is depleting its level of dissolved oxygen, particularly near the river bed, triggering a condition known as hypoxia, in which aquatic life cannot survive. The team has found such hypoxic conditions at two stretches on the Ganga river - downstream of Assi drain in Varanasi and downstream of Wazidpur drain in Kanpur. Experts warned that such conditions are affecting not only the Ganga river but all other rivers including Yamuna and the way to prevent fragmentation of river beds is to ensure ecological flow of the rivers.
