The epiphreatic zone, also known as the capillary fringe, is a subsurface layer located just above the water table in an unconfined aquifer. This zone is characterized by the presence of soil pores that are filled with both water and air. The water in this zone is held by capillary forces and is not under pressure, unlike the groundwater below the water table.
