Sinking Land Crushes California Groundwater Storage Capacity

Unbridled pumping of aquifers in California’s San Joaquin Valley is severely reducing the land’s capacity to hold water, according to a Stanford University study. The loss of storage is due to subsidence, which is the compaction of soils as a result of removing too much water. The study, which provides the first estimate of the permanent loss of groundwater storage space that occurred during a drought from 2007 to 2010, also shows that California lost natural water storage capacity equal to a medium-sized reservoir.
