Commentary: California Must Embrace Groundwater Management, And Expand It

We all walk on water. Not literally, but most Californians do walk over the water stored in the aquifers beneath our feet.

This unseen resource is groundwater, which provides 40% of our water supply in normal years, and up to 60% of our supply in times of drought.

With dry periods expected to increase in frequency and duration, groundwater is key to creating a more resilient water supply for drinking water, producing food, and sustaining our precious natural resources. Yet despite its importance, groundwater use in California has been largely unregulated.
