Groundwater from aquifers can be extracted using a water well. Water from aquifers can be sustainably harvested through the use of qanats. Aquifers vary greatly in their characteristics. A confined aquifer is an aquifer bound between two aquitards (a formation of low-permeability materials), and whose groundwater is under pressure greater than atmospheric. From: Environmental Monitoring and Characterization, 2004. View all Topics. Add to Mendeley. 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.
