Only 0.76% of all of planet Earth’s water is potable! It is one of the scarcest planetary resources. Water is essential to all life forms and is quickly becoming a rare resource. Natural mineral water sources are even scarcer and volcanic mineral water sources the scarcest of all.
Spring water sources are object of increasing contamination: across the water cycle, water molecules are exposed and may interact with multiple contaminants, from deforestation and forest fire sediments, to industrial and agricultural chemicals infiltrating through the soil, rivers and aquifers, to vehicles and industrial emissions to the atmosphere, accidental oil spillages at sea, and more.
This is not the case of waters stored inside volcano dormant calderas, which are kept inside these massive natural vaults for centuries, even millennia, and do not integrate as actively the water cycle. Our waters are naturally filtered through multiple and mineral-rich layers of rock being then kept for ages inside the volcano caldera, a process which protects it to a higher degree from all human contaminants in the air, aquifers, and atmosphere. These waters are kept away from all sources of human pollution: inside the dormant Furnas volcano caldera, in the Azores.
