Satellites Unlock Secret to Northern India's Vanishing Water

PASADENA, Calif. – Using NASA satellite data, scientists have found that groundwater levels in northern India have been declining by as much as 33 centimeters (1 foot) per ye...............

TOXIC As Re: Ground Water in northern India is dropping.

not only that, the groundwater that is being pumper out of the aquifer too quickly is largely toxic, as it contains high levels of dissolved arsenic. Uttar Pradesh is the area with the greatest amount of aquifer loss:

Arsenic in groundwater threatens millions in UP
Deepak Gidwani / DNAThursday, August 27, 2009 1:00 IST Email

Lucknow: Water is the elixir of life. But in thousands of villages across Uttar Pradesh (UP) it is causing death and diseases.

Hand pumps in these villages are marked with red crosses to indicate that the water is poisonous. But left with no choice, villagers continue to drink the water and fall victim to diseases, including skin cancer. The reason for this hydrological scourge is the presence of alarming levels of arsenic in groundwater in several districts of the state.

In a recent survey of UP's 49 districts,the UP Jal Nigam (UPJN) in collaboration with Uniceffound that the arsenic content in groundwater at many places was several times the prescribed limit.

As per World Health Organisation (WHO) guidelines, safe arsenic content in drinking water is 10 ppb (parts per billion) which works out to 0.01 mg per litre. But at several places in UP, the arsenic content measured up to 200 ppb. Government of India guidelines in this regard are more liberal and consider up to 50 ppb within normal limits.

Groundwater resides beneath the soil surface in permeable rock, clay and sand as illustrated in this conceptual image. Many aquifers extend hundreds of feet underground and in some instances have filled with water over the course of thousands of years.

The impact of India doesn't seem to have been mitigated at all. A land bridge between India and the Asian mainland was not established until the Eocene. However, the continental shelves of Asia and India had been in contact for some time before this, and elevation of the Himalayas has been ongoing throughout the Cenozoic. Initially, most of the impact was in the East, as India attempted to subduct under Asia to become the basement level of Tibet.

The India sub-continent is making higher and the right. The error was of age recently.

It's good to know, as there are other water's receding, much like the Hudson Bay, a very low lying body of water is rising, much faster than the ocean itself. This isostatic uplift, caused by asteroid impact, if it were caused by the ice, all of the surrounding land around hudson bay should have been left unchanged. That is why there is so much sand around, and under the sea. Flooding, then freezing, then melting, then uplift, then drying.
