From Arizona State University:
The availability of water from underground aquifers is vital to the basic needs of more than 1.5 billion people worldwide, including those of us who live in the western United States. In recent decades, however, the overpumping of groundwater, combined with drought, has caused some aquifers to permanently lose essential storage capacity.
With the hope of providing water resource managers with better tools to help keep aquifers healthy, a team of scientists from Arizona State University and the Jet Propulsion Laboratory (JPL) are using the latest space technology to look underneath Earth’s surface to measure this precious natural resource.
They’ve focused their efforts on one of the world’s largest aquifer systems, located in California’s Central Valley, measuring both its groundwater volume and its storage capacity. The results of their most recent findings in this groundbreaking study have been recently published in Water Resources Research.
