Aquifers are underground layers of permeable rock or sediment that hold and transmit water. They act as natural storage tanks, providing a source of freshwater for wells and springs.
Water that is stored in and moves through aquifers underground.
Recharge: The process by which water replenishes an aquifer, usually through precipitation seeping into the ground.
Overpumping: Extracting more water from an aquifer than can be naturally replenished, leading to depletion and potential long-term damage.
