The Southern Hills Aquifer System covers approximately 14,000 square miles of southeast Louisiana and southwest Mississippi. It is a system made up of alternating layers of water separated by barrier materials much like a layer cake.Rapid-infiltration pits: One way is to spread water over the land in pits, furrows, or ditches, or to erect small dams in stream channels to detain and deflect surface runoff, thereby allowing it to infiltrate to the aquifer. Groundwater injection: The other way is to construct recharge wells and inject water directly into an aquifer.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.
