Approximately 71 percent of the Earth's surface is covered by water. This water evaporates and rises as water vapor. Upon cooling down in the higher layers of the atmosphere it condenses, falling back to earth as precipitation. The rain seeps into the Earth's lower layers (hypolimnion) or gathers as surface water in lakes and rivers.
Gerolsteiner Mineral Water is also part of this cycle. It makes its way through the ground of the Eifel, deep into the Gerolstein Basin – and back up again to be bottled.
