the answer is beneath your feet

California is facing some worrisome pressures from increasing water demand for a growing population and decreasing supply reliability due to climate change and environmental pressures on the Bay-Delta region.  What should California do, when faced with extreme drought?  A new study released by the California Energy Commission recommends creating and maintaining a water storage bank underground.  That is, California should store excess water underground, and then pump it out as needed when extreme drought arrives.  I’ve been a fan of this idea (“Managed Aquifer Recharge” or “Managed Underground Storage” are two broad names for the idea) since I first heard about it some 6 years ago in grad school, and it’s great to see that policy advisers and think-tanks are starting to come around.  If we can educate the rest of California, including politicians, then we might actually have a shot at making things happen.
