Oct 16, 2019 · These rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground. When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. According to geological terms an Aquifer could be referred to as a body of saturated rock or geological formation through which water can easily move (permeability) into wells and streams ( Figure 1 ). The top of the water level in an aquifer is called the water table.

Pumping in confined aquifers decreases the water pressure, but the pore space remains fully saturated. 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 ... Karst aquifers are a vital groundwater resource in the United States. In the United States, about 40% of the groundwater used for drinking comes from karst aquifers.
