groundwater

Welcome to Clean Water Action California’s Program Update! Read all about what we're working on to protect California's groundwater. Thank you for your support of this work and for being part of the solution!

Groundwater is a huge part of California's climate adaptation plan, as hotter and more extreme weather will make our surface water supplies less reliable. Over the past two decades, a period that experts now consider a mega-drought, groundwater users pumped record amounts of groundwater, resulting in thousands of dry wells and severe land subsidence in areas of the state.
