The Uttar Pradesh government, citing a scientist, has asserted that Ganga water at the ongoing Maha Kumbh in Prayagraj is as pure as "alkaline water", debunking concerns raised by the Central Pollution Control Board (CPCB) about water quality. The government claims that a scientist found no bacterial growth or decline in the water's pH level, despite millions of devotees bathing in the river. However, experts caution that the quality of the Ganga water is not static and can vary greatly depending on various factors.
