What is an aquifer?
Quick Answer
An aquifer is an underground layer of rock, sand, or gravel that stores and transmits groundwater. Many wells and springs draw water from aquifers.
The Full Story
Aquifers are porous underground formations that hold water in spaces between grains or within cracks in rock. They can be shallow or deep and may supply drinking water, irrigation, and industrial needs. Some aquifers recharge quickly through rainfall, while others contain ancient water that was stored thousands of years ago. Major aquifer systems include the Ogallala Aquifer in the United States and the Great Artesian Basin in Australia. Because aquifers are often hidden underground, they can be overused before depletion is noticed.
