Evian natural spring water starts as rain and snow that falls onto a glacial plateau in the French Alps in an area created 50,000 years ago during the Ice Age when glaciers melted and created a unique geological landscape. The water naturally filters through layers of protected underground rock for over 15 years. When it emerges at the evian source; it contains naturally occurring electrolytes and minerals and a neutrally balanced pH of 7.2, which gives evian its unique, crisp taste. The water emerges at the foot of the alps in the town of Évian-les-Bains, where the evian spring was first discovered over 200 years ago. While there are many different types of bottled water, spring water comes from an underground formation called an aquifer from which water flows naturally to the surface of the earth at a source where it can be collected. Evian natural spring water is collected and bottled from Cachat Spring in the French Alps.
