VOSS Artesian Water from Norway comes from an aquifer in the pristine natural environment of Southern Norway, producing pure water like no other. This water is collected from an underground aquifer deep beneath the surface under layers of sand and gravel. Because the water is naturally filtered, it is free of contact with the air and other pollutants. Purity of water is defined in part by the mineral level found in specific bottled waters and is referred to as Total Dissolved Solids (TDS). TDS levels in VOSS are extremely low in comparison to other leading bottled waters.
