A water table--or unconfined--aquifer is an aquifer whose upper water surface (water table) is at atmospheric pressure, and thus is able to rise and fall. Water table aquifers are usually closer to the Earth's surface than confined aquifers are, and as such are impacted by drought conditions sooner than confined aquifers. Learn more:Background.

What is an aquifer system? Recharging Aquifers: Aquifers are a vital source of water in many parts of the world where precipitation does not meet the needs of the local population. An aquifer is defined as a geological formation made up of one or more layers of rock; water can be stored and flow out of aquifers.
