Question

what happens when an aquifer does not have a lateral or vertical recharge area? it turns into an unconfined aquifer. it can be used to source a flowing well. it will eventually dry up. it turns into a confined aquifer.

Explanation:

An aquifer needs recharge (lateral or vertical) to replenish water. Without it, water extraction (by natural processes or human use) will deplete the aquifer over time as there's no new water coming in. An unconfined aquifer is defined by having a water - table that can interact with the surface (not related to lack of recharge in this context). A flowing well (artesian well) in a confined aquifer depends on pressure from confining layers, not on lack of recharge. And an aquifer doesn't "turn" into a confined aquifer just because of lack of recharge (confined aquifers have specific geological confining layers).

Answer:

It will eventually dry up.
