California’s groundwater is threatened – unsustainable use is causing impacts around the state. Pumping during the drought has been so rapid that changes in groundwater levels can be observed from space. In some areas, the land surface has collapsed almost two inches per month. Deep new wells take water from neighbors in a race to the bottom.

There is reason for hope. A historic new state law provides new impetus toward sustainable groundwater management. The law, the Sustainable Groundwater Management Act, seeks to put groundwater management in California on a sustainable path. But passing the law was only the beginning.
