"One-third of Earth's largest groundwater basins are under threat because humans are draining so much water from them, according to two new studies. What's more, researchers say they lack accurate data about how much water remains in these dwindling reservoirs.
The studies found that eight of the world's 37 biggest aquifers are
"overstressed," meaning not enough water is replenished to offset the usage. Topping the list of overstressed aquifiers is the Arabian Aquifer System, located beneath Yemen and Saudi Arabia, from which 60 million people draw their water.
Groundwater pumping in California's Central Valley is also rapidly depleting the state's vast aquifer system, the researchers said. This over pumping is exacerbated by the drought in California, which is now in its fourth year. Currently, 99 percent of California is experiencing drought conditions, and 47 percent of the state is considered to be in "exceptional drought," msn
