Groundwater in California’s Central Valley may be unable to recover from past and future droughts

Groundwater in California's Central Valley is at risk of being depleted by pumping too much water during and after droughts. Under a best-case scenario, the researchers found there is a high probability it would take six to eight years to fully recover overdrafted water, but current California climate projections suggest realistic recovery times are even longer.
