LOS ANGELES TIMES - Groundwater supplies also take years to rebound, said Hoori Ajami, assistant professor of groundwater hydrology at UC Riverside, who is part of a team of researchers that analyzed data from wells affected by climate for a paper currently in peer review.
“Once your precipitation has recovered, that doesn’t mean your stream flow is recovered or your groundwater is recovered,” she said. “Our estimate is it could take for groundwater between three to 10 years on average to recover.”
