Answer:
It’s a rare sight in Varanasi. The Ganga is shimmering and is so transparent that one can see its aquatic life, such as fish and tortoise, deep in the water. It's all thanks to the nationwide lockdown to curb Covid-19 and the cessation of polluting activities.

“What could not be achieved in the last 34 years since the inception of Ganga Action Plan (GAP) in 1986, and the launch of Namami Gange in 2014, with hundreds of crores of rupees being pumped in, is visible in just 34-35 days of lockdown,” said Prof B D Tripathi, chairman of Mahamana Malaviya Research Centre for Ganga, River Development and Water Resource Management, Banaras Hindu University (BHU).
He acknowledged that more needed to be done. “While it is true that the quality of Ganga water has improved, but we can’t claim that the river is 100% free from pollution. In fact, just 25-30% reduction in pollution level is being noticed,” he said.
The impact of the lockdown on Ganga’s health is, nevertheless, encouraging and proves that by undertaking more measures water quality can be improved even further. Specifically, there has been significant improvement in the health indicators of Ganga’s water — an increase in dissolved oxygen (DO) and reduction in biochemical oxygen demand (BOD) — during the lockdown. BOD level indicates the amount of decaying organic matter in water, a low BOD indicating good quality. Low DO level signifies poor quality. If dissolved oxygen levels decline, aquatic life is impacted badly. Fecal coliform count (FCC), the primary indicator of potability, has also declined.
