Millions of Drinking Wells Worldwide Could Run Dry
Over-pumping, drought, and climate change are all factors depleting global groundwater resources. Up to 20 percent of the world’s drinking wells might be encountering impending doom. Without clean, fresh drinking wells, billions of people could be in a water crisis. According to research published in the journal Science , construction records from 39 million wells scattered across 40 countries were analyzed. The depths were examined and compared to groundwater levels, supported by data from previous studies. Debra Perrone, a water resources expert at the University of California, Santa Barbara, co-authored the study and said, “We found that this undesirable result is happening across the world, from the western United States to India.” The researchers found that millions of wells reached less than 16 feet below the water table, putting them susceptible to running dry. At least six to 20 percent of the wells evaluated appear to be in peril. Especially in places already affl...
