Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [1] Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and/or reclaimed water is routed to the subsurface.
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.
The groundwater is of meteoric origin [3] (the term meteoric water refers to water that originated as precipitation; most groundwater is meteoric in origin). High concentrations of sodium, chloride, and sulfates reflect the leaching and dissolution processes of gypsiferous shales and clay, in addition to a lengthy duration of water residence. [ 4 ]
California’s San Joaquin Valley may be sinking nearly an inch per year due to the over-pumping of groundwater supplies, with resource extraction outpacing natural recharge, a new study has found.

The groundwater supply across the country is depleting at an alarming rate. A new study found that groundwater supplies around the world are depleting faster than they were 40 years ago.
The coastal groundwater system consists of terrestrial groundwater, seawater and a mixture of two. Rainfall is the main source of the recharge of terrestrial groundwater. In the mixing zone, dilution occurs that results in the different chemical compositions of water there.
The first agriculture ASR wells were put into service in Oregon in the autumn of 2006 and have injected well over 3,000 acre-feet (3,700,000 m 3) of water during the winter and spring flood flow times using artificial recharge (AR) of flood water as their water source. This shallow recharged water is then recovered as potable water and injected ...
