About 500 billion gallons of surface water, and a larger unknown amount, are locked up in the minerals that form the mantle of the earth.

This water is a finite resource moving in never ending cycles across the earth. Very little of the water on earth is available as fresh water.

Two-thirds of the surface of the earth is covered by water, 97% of, which is salty, and approximately 2% is trapped in the polar ice caps. Only 1% of all water is contained in the air, rivers, lakes and underground.

The global availability of this small amount of freshwater together with continuous contamination from human activities make preservation of the supply of freshwater one of the major global issues.

With water being such a precious commodity without which life on earth could not exist measures need to be taken to ensure that all fresh water supplies remain safe to drink, and that all people have access to fresh water.
