[font size=3]Californias drought-stricken Central Valley harbors three times more groundwater than previously estimated, Stanford scientists have found. Accessing this water in an economically feasible way and safeguarding it from possible contamination from oil and gas activities, however, will be challenging.
Its not often that you find a water windfall, but we just did, said study co-author Robert Jackson, the Michelle and Kevin Douglas Provostial Professor at Stanford. Theres far more fresh water and usable water than we expected.
The
research, published in the journal
Proceedings of the National Academy of Sciences the week of June 27, highlights the need to better characterize and protect deep groundwater aquifers not only in California but in other parched regions as well.
Our findings are relevant to a lot of other places where there are water shortages, including Texas, China and Australia, said study co-author Mary Kang, a postdoctoral associate at Stanford School of Earth, Energy & Environmental Sciences.
