An aquifer is an #underground layer of #rock or soil that cont | Geology of the world and the Environment

An aquifer is an #underground layer of #rock or soil that contains water. The water is held in the spaces between the rock or #soil particles. There are two kinds of aquifer:

1. a #confined aquifer is a water supply which is sandwiched between two #layers of soil or rock that water can not pass through ( #impermeable layers ),

2. an #unconfined aquifer is a water supply that has an impermeable layer below it, but not above it. A confined aquifer that is under pressure is an #artesian aquifer. The pressure can often push water to the surface in a well drilled into an artesian aquifer; usually wells need a pump to bring water to the surface from the aquifer they are drilled into.

We use #aquifers as a source of drinking water and of water to irrigate crops or to use in industry, #pumping water from the aquifer using a well. As with any container of water, pumping from the aquifer empties it--or at least decreases the amount of water it holds. Aquifers are refilled, or recharged, in areas where they are exposed on the surface of the earth. Water can re-enter the aquifer in these recharge areas.
