Yes, some aquifers are not replenished, and consist of finite quantities of water.They are sometimes called fossil aquifers. More commonly though, aquifers have inflow and outflow, although these flow rates can vary. If the extraction rate is faster than than the replenishment rate an aquifer can and does become depleted..

from an aquifer
An aquifer is an underground layer of rock, sand, or gravel that contains groundwater.
impermeable
Water in rocks (or other porous material) below the ground is called ground water.

an underground layer of rock that can hold water is an aquifer.
Water can eventually reach a layer of impermeable rock which does not allow its further downward passing. This is the base layer which creates the aquifer.
