Pollution of the Ganges or Ganga , the largest river in India, poses significant threats to human health and the larger environment. Today, the Ganges is considered to be the sixth-most polluted river in the world. However, pollution has been an old and continuous process in the river as by the time people were finally speaking of the Ganges as polluted, stretches of over six hundred kilometres were essentially ecologically dead zones. A number of initiatives have been undertaken to clean the river but failed to deliver as desired results. The main cause of water pollution in the Ganges river are the increase in the population density, various human activities such as bathing, washing clothes, the bathing of animals, and dumping of various harmful industrial waste into the rivers. The river flows through cities with populations over ,; 97 cities with populations between 50, and ,, and about 48 towns. The ash is dumped into ponds from which a slurry is filtered, mixed with domestic wastewater, and then released into the Pandu River.

The excessive amounts of human waste and toxic effluents that find their way into the Ganga river are not only polluting the water but also causing deficit of dissolved oxygen in the riverbeds in some of the most polluted stretches of the river, a new study has found. Dissolved oxygen is an important parameter that determines health and rejuvenation capacity of any riverine ecosystem. The amount of dissolved oxygen in a river depends on atmospheric supply of oxygen, photosynthetic process, and oxygen-consuming metabolic and chemical processes. If dissolved oxygen falls below the threshold of 2 milligram per liter, it can lead to mass killing of fish and harm other aquatic life. Researchers measured sediment oxygen demand that includes the biological as well as chemical oxygen demanding processes occurring in the riverbed sediment. The study was done along the stretch of the river between Varanasi and Kanpur; and downstream to two major drains Wazidpur in Kanpur and Assi in Varanasi.

Water pollution is one of the biggest issues facing India right now. As may be evident, untreated sewage is the biggest source of such form of pollution in India. There are other sources of pollution such as runoff from the agricultural sector as well as unregulated units that belong to the small-scale industry. The situation is so serious that perhaps there is no water body in India that is not polluted to some extent or the other. This is especially applicable of ones that some form or the other of human habitation in their immediate vicinity. Ganga and Yamuna are the most polluted rivers in India. The single biggest reason for water pollution in India is urbanization at an uncontrolled rate.
