Environmental Scientists: Up To 20% Of Global Groundwater Wells At Risk Of Going Dry by Bob Yirka

In their paper published in the journal Science, Scott Jasechko and Debra Perrone describe their analysis of groundwater well construction data from millions of wells around the world. The researchers were able to draw conclusions about the state of groundwater levels. They found that between 6 and 20% of all of the wells around the world currently sit at no more than 16 feet below the water table in which they exist. They note that this means that they are at risk of going dry in the coming decades. They also found that new well construction has, in many instances, not taken into consideration the reduced levels of groundwater, and therefore have not been dug deeper than older wells. They suggest this practice will lead to the new wells running dry just as quickly as the older wells.
