Definition Aquifers that contain perched groundwater i.e. bodies of groundwater separated from an underlying body of groundwater by an unsaturated zone. Description A perched aquifer occurs above the regional water table and is generally a relatively small body of water with an impermeable base under which lies an unsaturated zone. These are unique water bodies not widely distributed and are not targeted for water supply. Why are perched aquifers important? These aquifers can be a localised source of water which can feed springs.
