• A report by the Uttar Pradesh Pollution Control Board has revealed that the BOD (Biological Oxygen Demand) in the Ganga near downstream Jana village in the industrial city of Kanpur is 4.60 mg per litre. Here in the Ganges, a total of 20 thousand coliforms and fecal coliforms have been found to be 17 thousand.
• In the Sangam area of Prayagraj, the BOD of Ganga was found to be a maximum of 2.90 mg per litre, which can be considered satisfactory.
• In the report, the pollution of the Varuna River that meets the Ganges has been described at an alarming level. Varuna's BOD was found to be 12.40 mg per litre before it joins the Ganga in Varanasi.
• According to the board's report, Varuna's water has also become very dangerous for aquatic organisms. Varuna's DO (Dissolved Oxygen) is 3.30 mg per litre before it joins the Ganga.
