Concept in Definition ABC

The term aquifer is used to refer to those geological formations in which water is found and which are permeable, thus allowing the storage of water in underground spaces. Aquifer water is not normally at provision simple or immediate of the human being since it is underground (except that in some part of its extension it approaches the surface. For this reason, in order for humans to take advantage of this type of water, they must carry out excavations and wells. In many cases, the water can be many meters deep.

Aquifers form naturally when the land surface absorbs water from rain. This process of absorption It occurs because the land on the earth's surface allows water to enter as it is permeable (earth, sand, clay, etc.). Once absorbed, the water forms underground layers until it reaches a non-permeable zone in which the composition The rock is more closed and therefore the water does not pass as easily. Aquifers are then formed by these two layers of water: the confined and the unconfined. Unconfined aquifers are those that can be used by humans through excavations. The water that remains in the confined aquifers is more difficult to access, not only because it is more

distance if not because also the rock is more difficult to excavate.

As the water is absorbed by the different layers of earth, it loses velocity and it slowly begins to be deposited in a natural way between the different layers that are formed by different materials. The deeper the water, the slower the water will arrive and, in addition, by counting the areas of confined aquifer with higher pressure, an excavator that goes up to this point will spurt the water on the surface with a lot of more violence than in the unconfined aquifer.
