420 Volcanic water is purified by the remains of an extinct volcano. It is sourced from at naturally occurring spring called Tai Tapu on New Zealand's South Island Banks Peninsula. The water collects in a nearly 200 meters below the volcano before slowly rising to the surface due to its own pressure. This water has been described as "volcanic artesian spring water." It is a soft water and alkaline in nature. The water comes packaged in a modern ribbed bottled that is highly collectible and which has won several awards for its unique design. Production of this water has now been discontinued.
