When groundwater is extracted from an aquifer, a cone of depression is created around the well.As the drafting of water continues, the cone increases in radius. Extracting too much water (overdrafting) can lead to negative impacts such as a drop of the water table, land subsidence, and loss of surface water reaching the streams.

Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
This groundwater is a major source of fresh water for many regions, however can present a number of challenges such as overdrafting (extracting groundwater beyond the equilibrium yield of the aquifer), groundwater-related subsidence of land, and the salinization or pollution of the groundwater.
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 ...
The rate of groundwater recharge is the time it takes for groundwater to replenish itself and extremely slow, leading to water shortages, as humans remove water from aquifers faster than the rate of recharge. [16] Due to such slow circulation of water, groundwater can remain polluted for decades, as the natural purification processes are so slow.
California's groundwater levels rose significantly in 2023, one of the wettest years in decades. State officials say efforts to replenish aquifers helped.
