Three areas in the San Joaquin Valley have been significantly affected by land subsidence as a result of groundwater pumping: "(1) 1500 mi 2 in the Los Banos-Kettleman City area, (2) 800 mi 2 in the Tulare-Wasco area, and (3) 400 mi 2 in the Arvin-Maricopa area" (Ref.

It explains the structure of aquifers, highlights key terms like water table and wells, and emphasizes the importance of balancing recharge and discharge for sustainability. The page warns that overuse can lead to water table decline and contamination, exemplified by the challenges facing the Ogallala Aquifer in the U.S.

It notes that 97% of Earth's water is saltwater, with just 3% fresh water, mainly as ice. The hydrologic cycle, driven by solar energy, moves water through evaporation, condensation, and precipitation. Concerns about groundwater overuse and the importance of water conservation policies are addressed.

The state's water system is the world's largest and most controversial, managing over 40 million acre-feet annually. Water rights are politically divisive, exacerbated by climate change predicting more droughts and alterations in precipitation. Debates focus on whether to redistribute water for urban and agricultural needs.
