Home to glaciers, spouting geysers, volcanoes and raging rivers, Iceland is one of the world’s cleanest ecosystems. It’s also home to the legendary Ölfus Spring, the source of Icelandic Glacial.  Formed more than 5,000 years ago and shielded by an impenetrable barrier of lava rock, the Spring is constantly replenished by rain, snow and ice-melt from the nearby mountains.  The water is slowly and naturally filtered through layers of volcanic rock, thereby producing a natural spring water so pure that nothing is added or taken away.
