Polluted water making Ganga’s river bed unfit for sustaining aquatic life, says new research
Hindustan TimesIt’s not just the surface, River Ganga is polluted from deep inside, a new research has found. The scientists have found millions of litres of waste water, containing toxic elements and metals, is dumped in the Ganga, thereby depleting the level of dissolved oxygen in its water, particularly near the river bed, triggering a condition known as hypoxia, in which marine life cannot survive. While the Assi drain carries around 66 million litres of domestic waste water into the river, the Wazidpur drain carries around 54 MLD comprising mostly industrial waste. This is making the water quality at the bottom of the river and the river bed unfit for sustaining life,” said Pandey. In January this year, the Central Pollution Control Board published a study titled “Biological Health of River Ganga” which said that there was no improvement in the overall water quality of the Ganga, including in the stretches where Gangetic dolphins are found.
