In reality, many aquifers fall between the two extremes. For example, a coastal aquifer may be confined by sedimentary deposits near the coast but unconfined further inland.Aquifer Storage & Recovery (ASR) Aquifer Storage and Recovery (ASR) wells are part of a system to take surplus fresh surface water, treat it as required for permit compliance, and then store it in the Floridan Aquifer System (FAS) for subsequent recovery during dry periods.Aquifer Storage & Recovery (ASR) Aquifer Storage and Recovery (ASR) wells are part of a system to take surplus fresh surface water, treat it as required for permit compliance, and then store it in the Floridan Aquifer System (FAS) for subsequent recovery during dry periods.

An aquifer may be a layer of gravel or sand, a layer of sandstone or limestone, or a buried rubbly old lava flow - as long as material is saturated enough that it can yield significant quantities of water for extraction. Water is a solvent and dissolves minerals from the rocks with which it comes in contact, so groundwater may contain …
By definition the head of a confined aquifer is higher than the top of the aquifer, so the complete thickness of the confined aquifer is saturated, thus b is a constant when T is determined. The saturated thickness of an unconfined aquifer varies with space as the water table slopes in the direction of flow, thus, T values change with distance ...
