3 June 16, About one third of Earth's largest groundwater basins are being rapidly depleted by human consumption, despite having little accurate data about how much water remains in them, according to two new studies led by the University of California, Irvine (UCI), using data from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites

4 Findings In a companion paper published in the same journal, the scientists conclude that the total remaining volume of the world's usable groundwater is poorly known, with estimates that often vary widely. The total groundwater volume is likely far less than rudimentary estimates made decades ago. By comparing their satellite-derived groundwater loss rates to what little data exist on groundwater availability, the researchers found major discrepancies in projected "time to depletion." In the overstressed Northwest Sahara Aquifer System, for example, time to depletion estimates varied between 10 years and 21,000 years. "We don't actually know how much is stored in each of these aquifers. Estimates of remaining storage might vary from decades to millennia," said Richey. "In a water-scarce society, we can no longer tolerate this level of uncertainty, especially since groundwater is disappearing so rapidly."

6 California Regulations New regulations in California which have gone into effect at the beginning of 2015 require impacted groundwater basins to establish local groundwater sustainability agencies and develop monitoring plans for sustainability by These regulations affect a wide range of parties who have an important interest in the resources of a specified basin either because they use the groundwater, practice activities that could cause groundwater pollution, or because they are concerned with environmental management. The participation of these stakeholders is essential because it disseminates understanding of issues in sustainable use of groundwater, it enables management activities such as monitoring and inspecting to be carried out effectively, facilitates coordination of decisions relation to groundwater, and more.
