License to pump: New web portal examines, compares and explains the permitting process of groundwater pumping across seven U.S. states.

Overpumping groundwater poses a major threat to the availability of a critical resource, especially in the arid lands of the Southwestern United States. States across the region have sought to deal with this issue through a wide variety of regulations and permitting processes. A new dashboard tool, created by affiliates from Stanford’s Water in the West program, compares groundwater withdrawal permitting – a common tool used by resource managers to limit groundwater pumping – to help plan for a more sustainable future.

“Western states have adopted a wide range of approaches towards regulating groundwater pumping, but information about these approaches are not always shared across the region. Our goal is to help parties in different states learn from what is happening elsewhere. This is particularly important in California, where local agencies are working to implement the Sustainable Groundwater Management Act,” said Leon Szeptycki, executive director of Water in the West and a dashboard contributor.
