Icelandic Glacial is sourced from the legendary Ölfus Spring in Iceland, one of the world's largest natural springs. The spring is constantly replenished by gradual filtration of abundant rainfall and snowmelt inherent to Iceland and has been declared sustainable by Zenith International. Of the more than 900,000 cubic meters of water flowing into the ocean everyday, Icelandic Glacial™ bottles less than 0.1% of the overflow into the sea.
