"Scientists have discovered that the pace of groundwater depletion in California’s Central Valley has accelerated dramatically during the drought as heavy agricultural pumping has drawn down aquifer levels to new lows and now threatens to devastate the underground water reserves.
The research shows that chronic declines in groundwater levels, which have plagued the Central Valley for decades, have worsened significantly in recent years, with particularly rapid declines occurring since 2019.
“We have a full-on crisis,” said Jay Famiglietti, a hydrology professor and executive director of the University of Saskatchewan’s Global Institute for Water Security. “California’s groundwater, and groundwater across the southwestern U.S., is disappearing much faster than most people realize.”"
