aquifer

(ăk`wĭfər): see artesian wellartesian well,
deep drilled well through which water is forced upward under pressure. The water in an artesian well flows from an aquifer, which is a layer of very porous rock or sediment, usually sandstone, capable of holding and transmitting large quantities of water.

Aquifer

Any underground water-bearing rock formation or group of formations that supplies groundwater, wells, or springs.

Aquifer

 

a stratum or several strata of water-permeable rock, whose pores, cracks, or other cavities are filled with groundwater. Several aquifers hydraulically connected to each other form an aquifer complex.

aquifer

[′ak·wə·fər]
(geology)
A permeable body of rock capable of yielding quantities of groundwater to wells and springs.
(hydrology)
A subsurface zone that yields economically important amounts of water to wells.

aquifer

A water-bearing formation of gravel, permeable rock, or sand that is capable of providing water, in usable quantities, to springs or wells.

aquifer

a porous deposit of rock, such as a sandstone, containing water that can be used to supply wells

The study reveals natural discharge of groundwater from the deeper Nubian aquifer into the shallower alluvial aquifer.
Groundwater recharge, defined as the addition of water to the aquifer once it has reached the water table, can happen in several ways:
By being a sole-source aquifer, the water has come under both state and federal regulations and has been the subject of lawsuits by private and industrial groups claiming the state has overstepped its authority.
There is a lot of potential in the groundwater, but it can only be used sustainably if we understand the amount of water in the underground aquifers, the water quality, how the aquifers refill themselves, and how much of the water can be abstracted without depleting the storage, said Calvince Wara, research operations manager for Rural Focus.According to Pamela Ogada, the general manager at Kwale Sugar, yields from irrigated agriculture are always higher than those from rain-fed agriculture.
Several other scientists (Jeong et al., 2005; Ozebo et al., 2008; Rao et al., 2008) have used electrical resistivity technique for demarcation of bedrock, estimation of aquifer properties, aquifer extension, and aquifer thickness in relation with hydrogeology of the study area.
