… In California, our groundwater system is out of balance. More water is going out than is coming in, which is causing a host of problems—falling water levels, domestic wells going dry, land subsidence, ecosystems under stress, and water quality problems. There’s a lot of space in the aquifers after all the groundwater pumping, and natural recharge isn’t filling it adequately. We could supplement with managed aquifer recharge (MAR). That means sending the excess water in wet years to locations where it can move downward and replenish our groundwater systems. Spreading water in a dedicated recharge basin, agricultural field, or floodplain could move it efficiently down below the surface, depending on the geologic characteristics of the site.
