en.wikipedia.org/wiki/Aquifer

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater can be extracted using a water well.The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or aquifuge ...

This type of well is called artesian. ... Groundwater occurs in the saturated soil and rock below the water table. If the aquifer is shallow enough and permeable enough to allow water to move through it at a rapid-enough rate, then people can drill wells into it and withdraw water. ... water will rise above the top of the aquifer and may even ...

The type of rock that works best as an aquifer is volcanic rock that fills in as rubble between flows. This type of rock is highly porous and rather permeable, permitting significant water movement. Other types of rock that work as aquifers include columnar basalt, sandstone, unconsolidated sand and gravel, conglomerate and fractured limestone.

Cracks in the basalt and the layers between flows form aquifers. In the river valleys there are layers of sand and gravel forming aquifers, sometimes separated by layers of clay. Bedrock with connected cracks forms aquifers in many parts of the state, especially in the hills above river valleys.

The third main type of aquifer is a perched aquifer (Figure 6). Perched aquifers occur above discontinuous aquitards, which allow groundwater to “mound” above them. Thee aquifers are perched, in that they sit above the regional water table, and within the regional vadose zone (i.e. there is an unsaturated zone below the perched aquifer).

1.5 Types of Geological Formations and Aquifers There are basically four types of geological formations (Aquifers, Aquitard, Aquiclude, and Aquifuge) 1.5.1 Aquifer An aquifer is a ground-water reservoir composed of geologic units that are saturated with water and sufficiently permeable to yield water in a usable quantity to wells and springs.

The weight of all the soil and rocks above this empty aquifer space can cause it to collapse. A collapse of an aquifer can cause a sinkhole, although the likelihood of a sinkhole depends on the ...

An aquifer is an underground layer of water-bearing rock.Water-bearing rocks are permeable, meaning they have openings that liquids and gases can pass through. Sedimentary rock such as sandstone, as well as sand and gravel, are examples of water-bearing rock.The top of the water level in an aquifer is called the water table. An aquifer fills with water from rain or melted snow that drains into ...
