What is Sustainable Groundwater Management?

The Sustainable Groundwater Management Act (SGMA) defines sustainable groundwater management as managing and using groundwater without causing undesirable results such as: chronic groundwater level declines, groundwater storage reductions, seawater intrusion, water quality degradation, land subsidence, and surface water depletions. SGMA requires that groundwater basins classified as either medium or high priority by the California Department of Water Resources achieve sustainable groundwater management within 20 years of adopting a Groundwater Sustainability Plan.
