The world is quickly running out of water: NASA | Quartz

The world is losing groundwater, fast.

That is the conclusion of a new study published by researchers at NASA, which drew on satellite data to quantify the stresses on aquifers. The researchers found that over the decade-long study of the 37 major aquifers worldwide, 21 experienced a depletion of their water supply. Especially alarming was the study’s finding that the Indus Basin aquifer, which supplies much of India’s water supply, has depleted rapidly.

“The potential consequences are pretty scary,” NASA scientist Matthew Roddell, a lead author of the study, tells Quartz. “At some point those aquifers might run dry.”

To measure the water level changes, the researchers studied the gravitational orbit of NASA’s Gravity Recovery and Climate Experiment (GRACE) satellite caused by the shifting of earth’s mass. Because water is one of the larger and constantly shifting masses on earth, this allowed them to measure changes to groundwater supplies.
