ARTESIAN APPELLATIONS is a term used to describe the names given to artesian wells, which are wells that tap into a confined aquifer and are able to bring up water without the need for a pump. NOMS is an acronym for 'Nomenclature des Origines des Eaux Souterraines' which is French for 'Naming of Underground Water Origins'. This system is used to assign unique names to artesian wells in order to identify them.
