EVIAN is all natural and perfectly pure. Each drop of EVIAN Natural Mineral Water falls as rain or snow high on the pristine peaks of the French Alps. It then travels through a vast mineral aquifer deep within the mountains before emerging at the Cachat Spring in Evian-les-Bains, where it is bottled at source. EVIAN's amazing journey to the Cachat Spring is the secret to its purity and it takes more than 15 years natural filtration. Through this process, EVIAN is filtered naturally, without chemicals, giving it the purity, mineral content, and taste that nature intended.
