Why Ganga Snan?
Hindus have always believed that water from India’s Ganges River has extraordinary powers. The Mogul emperor Akbar called it the “water of immortality” and always traveled with a supply. The British East India Co. used only Ganges water on its ships during the three-month journey back to England, because it stayed “sweet and fresh.”
Indians have always claimed it prevents diseases, but are the claims wives’ tales or do they have scientific substance?
In the fourth installment of a six-part series, independent producer Julian Crandall Hollick searched for the “mysterious X factor” that gives Ganges water its mythical reputation.
He starts his investigation looking for the water’s special properties at the river’s source in the Himalayas. There, wild plants, radioactive rocks, and unusually cold, fast-running water combine to form the river. But since 1854, almost all of the Ganges’ water has been siphoned off for irrigation as it leaves the Himalayas.
Hollick speaks with DS Bhargava, a retired professor of hydrology, who has spent a lifetime performing experiments up and down Ganges in the plains of India. In most rivers, Bhargava says, organic material usually exhausts a river’s available oxygen and starts putrefying. But in the Ganges, an unknown substance, or “X factor” that Indians refer to as a “disinfectant,” acts on organic materials and bacteria and kills them. Bhargava says that the Ganges’ self-purifying quality leads to oxygen levels 25 times higher than any other river in the world.
Hollick’s search for a scientific explanation for the X factor leads him to a spiritual leader at an ashram and a biologist in Kanpur. But his best answer for the Ganges’ mysterious substance comes from Jay Ramachandran, a molecular biologist and entrepreneur in Bangalore.
In a short science lesson, Ramachandran explains why the Ganges doesn’t spread disease among the millions of Indians who bathe in it. But he can’t explain why the river alone has this extraordinary ability to retain oxygen.

Polluted Ganga still has medicinal qualities

He said during the research it was found that E.coli could survivie for only three days in a three-day old sample of Ganga water. The bacteria survivied for seven days in the Ganga water sample collected eight years back while it lasted for 15 days in a 16-year old sample of the Ganga water.
The E.coli however survived for longer time in boiled water, he said. A study of factors affecting the survival of E. coli in Ganga water is of great interest due to its importance as an indicator of fecal pollution in natural waters. It is ancient knowledge that Ganges water does not putrefy, even after long periods of storage, thus water from the Ganges has for millennia been regarded as incorruptible, Dr Nautiyal said.
Dr Nautiyal says this quality of the Ganga water could be used to develop a new anti-biotic which could be more useful in fighting bacterial infections. “There is however need for more research in this regard”, he said.
Bacteriophages
Right. However, on more subtle aspect, any water that is balanced in tridosha, is know as Ganga water, has ability to cure tridosha imbalance.
