The island of Jeju sits off the coast of South Korea in the Korean Strait. It is on this small volcanic island where the bottled water known as 16 Jeju is sourced. Starting as rain the water makes its way into the ground where it travels through several layers of volcanic rock. The balanced ecosystem in this region makes the water a renewable resource so it does not place a hardship on the surrounding environment. As a brand of exotic bottled water, 16 Jeju is among the purest bottled waters available on the planet. The pristine environment of the island of Jeju helps preserve the water in its natural state. The number 16 was added to the name of the water to represent the different layers of rock it travels through on its journey to an underground spring. These layers of rock act as a natural filtration system, which also enhances the water with many beneficial minerals.
