New satellite data from NASA has given us the most complete picture to date of the state of the world’s largest aquifers, which provide fresh water for hundreds of millions of people.
The picture isn’t pretty. As the Post’s Todd Frankel writes, researchers found that 21 of the 37 largest aquifers passed their sustainability points in the decade they studied, meaning more water was removed from them than replaced. And researchers placed 13 aquifers in the “most troubled” category. The aquifers under the most stress are in poor, densely populated regions including northwest India, Pakistan and North Africa.
