Aquifer
An aquifer forms when groundwater pools between a permeable layer and an impermeable layer.
zone of aeration.
It is semi-permeable to water, in which water can pass it through the double lipid layer or through proteins crossing the double layer of the cell membrane.
This would be an aquifer. The rock itself would be described as being permeable or having a high hydraulic conductivity.
Permeable layers allow either all or only certain things in and out. The ground is permeable because it allows water to sink through it. Skin is also permeable because it takes in oxygen and liquids but it keeps other foreign objects out. The skin can let out waste by sweating.
An Aquifer.
An aquifer is a layer of permeable rock that contains water. It usually conducts groundwater and supplies the water for wells and springs.
An aquifer is not a type of water. It is an underground layer of permeable rock, sediment or soil that contains water. Wells are dug to reach this layer to obtain water.
A fully permeable layer is a layer that allows all substances to pass through. A partially permeable membrane is a membrane that only allows some substances to infiltrate.

An underground layer of water-bearing permeable rock or unconsolidated materials such as sand or gravel.
The permeable rock bearing the groundwater is an aquifer. If the impermeable rock layer at it's base (known as an aquiclude) is of limited lateral extent such that the groundwater level away from this area is much lower, then it may be known as a perched water table.
