Naming priorities such as better land management, an evolved portfolio of 21st-century solutions and more funding for research and development, Stanford experts highlight areas central to success as the Biden-Harris administration aims its sights on safeguarding U.S. drinking water.
Stanford researchers, in collaboration with groundwater managers, are leading an airborne survey effort to investigate where water from the Sierra Nevada Mountains could recharge groundwater aquifers in California’s Central Valley.
Stanford Earth's David Lobell, Rob Jackson, Erik Sperling, Dustin Schroeder, Sally Benson, Roz Naylor, Michael Machala, Rosemary Knight and Kate Maher have received funding for interdisciplinary research to solve major environmental problems.
Research by Rosemary Knight shows that unless action is taken, parts of the Central Valley will sink more than 13 feet over the next 20 years. Stopping it will require strategic replenishment of shrinking aquifers.
Pumping an aquifer to the last drop squeezes out more than water. A new study suggests it can also unlock dangerous arsenic from buried clays. Sinking land may provide an early warning and measure of contamination.
Ryan Smith, a doctoral candidate in geophysics, explains research he led showing that continued heavy pumping of groundwater in the Central Valley could threaten water supplies with arsenic contamination.
Geophysics professor Rosemary Knight comments on a study she co-authored showing that sinking land caused by intensive groundwater pumping in California is releasing trapped arsenic, a known carcinogen.
Stanford Earth’s Rosemary Knight recently spearheaded a project to map underground freshwater resources and forecast the intrusion of saltwater into aquifers beneath the California coastal town of Marina.
