The spring is in the Massif Central, at the crossroads of the Lyonnais mountains and the Forez plain. Before reaching its source in Saint-Galmier, a small town located in the Loire, the water falling from the sky follows a long underground journey during which it will experience profound metamorphoses. At the origin of such changes, a singular subsoil, which is characterized by the existence of deep fractures of the earths crust, born of a powerful tectonic activity millions of years ago. These faults allow the rise of carbon dioxide from the Earths mantle. Badoit is named after Auguste Badoit, who began bottling the water of Saint Galmier in 1838. In 1971, Badoit became part of Evian SA, which later became a fully owned subsidiary of Boussois Souchon Neuvesel. Today, Badoit is a product and brand of the Danone group.
