Water that has been stored in the Earth’s crust for thousands of years can still be contaminated by modern chemicals, a new analysis suggests. Researchers analyzed groundwater from over 6,000 wells around the world, and concluded that old groundwater accounts for the majority of groundwater from wells deeper than 250 meters. But the team made […]

Researchers used GPS measurements to show that land surrounding the valley is rising by between 1 and 3 mm per year, in response to draining of the underlying aquifer. The pattern is correlated with wet and […]
