Phreatic refers to geological formations or processes that involve groundwater. The term “phreatic” is
derived from the Greek word “phreas” which means well or spring. Phreatic zones are areas of the
subsurface where the pore spaces in soil or rock are completely filled with water. These zones can occur
at various depths depending on the geological conditions and the water table. Phreatic zones are
important sources of groundwater for drinking, irrigation, and industrial purposes.
