If California doesn't get rain this winter ...: ""Groundwater demand is normally around 40 percent a year," said Doug Carlson, information officer at the California Department of Water Resources ( DWR). "Now it's at 60 percent demand."
Carlson explained that groundwater is layered in clay and sandstone. Removing the water, he said, not only depletes the resource but often creates dangerous conditions of the earth sinking in on itself, which has already happened in parts of the state.
"Once that subsidence (collapse) happens, it's lost forever and rainfall won't replace it," he said."
