A perched water table (or perched aquifer) is an aquifer that occurs above the regional water table, in the vadose zone. This occurs when there is an impermeable layer of rock or sediment (aquiclude) or relatively impermeable layer (aquitard) above the main water table/aquifer but below the surface of the land.he water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0).
An aquifer is a body of rocks or sediment underground that holds water. An aquifer is like a warehouse that stores groundwater, or water captured below the surface. The age of the water in an aquifer can range from days old to thousands of years old. There are many reasons why aquifers are important.
