"New Map of Earth's Groundwater To Help Estimate When It May Run Out"

"LONDON - The first map showing the world's hidden groundwater was published on Monday, bringing us closer to estimating how much there is, and when it will run out if we over-use the resource.

Using data and computer models, an international team of researchers estimated that less than six percent and perhaps as little as one percent of water found close to the Earth's surface is renewable in a human lifetime.

'This has never been known before,' Tom Gleeson of Canada's University of Victoria and the lead author of the study, said in a statement."
