Question

Hii guys!!

Write the pollution level of major river systems in India.

Plz don't answer if u don't know!!

Answer 1

Guwahati’s role in Brahmaputra’s pollution is undeniable and the city has been a constant source of all sorts of pollution, causing the river significant harm. A Central Pollution Control Board (CPCB) study in 2012 found out that the faecal coliform bacteria level in the river water in Guwahati was 3,000 more probable number (MPN) per 100 mililitres, much more than the 2,500 that is the usual norm. The bacteriological oxygen demand (BOD) in Brahmaputra in Guwahati was worse than any tributaries. With 400 MPN per 100 ml was worse than Haridwar’s 268 per 100 ml in one of the most polluted areas of the river Ganga. Despite being Assam’s primary economic hub, Guwahati lacks a single stated-owned sewage treatment plant (STP), making matters worse for the river. River cleanup activities, though conducted under the Guwahati civic body’s watch can do little to have any effect on the river as the amount of pollution is unmatchable.

Answer 2

Answer:

The worst pollution, in decreasing order, were found in river Markanda (490 mg/L BOD), followed by river Kali (364), river Amlakhadi (353), Yamuna canal (247), river Yamuna at Delhi (70) and river Betwa (58).
