Volcanic brand of bottled water gets its name from the ring of volcanoes situated just off the western coast of the United States. Some of the volcanoes located within the Pacific Ocean sit on top of a tectonic plate known to have helped induce volcanic activity. This activity has left a bed of porous volcanic rock deep within the Ocean that acts as a natural filter for any water passing through. Fortunately, the water captured for the Volcanic brand travels through these layers of rock, which also endow it with essential minerals. The Volcanic brand is classified as a mineral water, with the label actually indicating the name to be Volcanic Mineral Refresher. The most significant minerals found in this water are magnesium, zinc and bicarbonate. Each mineral contains properties that benefit the body when ingested in a naturally alkaline beverage such as Volcanic. The water's 7.2 pH level gives it a somewhat sweet, yet refreshingly clean taste.
