Hindus have always believed that water from
India's Ganges River has extraordinary powers. The Indian 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.
