A saturated, spongy, and impermeable layer or stratum is what the phrase defines as an aquifer.
An aquifer is a rock that contains water and easily transports it to wells and springs. The aquifers can be penetrated by drilling wells and then filled with water. Rainfall replenishes the aquifer's permeable sandstone with water over time.
Stormwater, which is produced by precipitation and snowmelt, seeps into the earth until it reaches layers of rock formation, where it is trapped and stored underground, filling aquifers. The permeable rocks of aquifers are refilled by rainwater that seeps into the soil.
