Land subsidence from overpumping groundwater in the San Joaquin Valley has been called the largest human alteration of the Earth’s surface. When the last comprehensive surveys were made in 1970, subsidence in excess of one foot had occurred over more than 5,200 square miles (13,000 sq km) of irrigable land – half the entire valley.

Researchers from Stanford and the University of Calgary have transformed pulses of electrical current sent 1,000 feet underground into a picture of where seawater has infiltrated freshwater aquifers along the Monterey Bay coastline. The findings, which will be published in an upcoming issue of the Journal of Hydrology but are available online now, help explain […]
