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.
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 ...
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.
In response, interest is being generated around MAR projects that utilize recycled water to supplement other water sources. [6] Orange County 's Groundwater Replenishment System serves as an example of one such system that is combining recycled water and storm water to recharge groundwater through spreading grounds to meet the municipality's ...

Graphic on Groundwater Flow. Groundwater-Dependent Ecosystems (or GDEs) are ecosystems that rely upon groundwater for their continued existence. Groundwater is water that has seeped down beneath Earth's surface and has come to reside within the pore spaces in soil and fractures in rock, this process can create water tables and aquifers, which are large storehouses for groundwater.
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.
Factors that affect the recharge include the size of the area in which groundwater is captured, the amount of precipitation, the size of capture points, and the size of the spring outlet. Water may leak into the underground system from many sources including permeable earth, sinkholes, and losing streams .
