The water quality of Ganga river at Allahabad and Varanasi, two holy places where millions take a dip, is most unfit for bathing purposes... Water becomes unfit for bathing if the biochemical oxygen demand (BoD) level exceeds 3 mg per litre... the BoD level at Allahabad was 6.4, it was 3.4 at Varanasi, 4.5 at Kanpur and 3.9 at Kannauj, making the Ganga unfit for bathing, what to talk about drinking.” “The biggest culprit is domestic sewage. According to Indian government figures compiled by the Centre for Science and Environment, an advocacy group based in New Delhi, 2.7 million liters per day of sewage is generated by the 50 cities along its banks…. The same agency categorizes 764 ‘grossly polluted' factories, including chemical plants, slaughterhouses and textile factories. Additionally, the loss of freshwater flow into the river from hydroelectric dams and agricultural irrigation means that some stretches of the river receive no freshwater flow during winter and summer months – only wastewater… Sewage treatment plants have been built in cities all along the river, but many don't operate at full capacity because of a lack of electricity. Another problem is India's decentralized approach to governance.
