Our bottled water is protected by a multi-barrier approach, which includes steps such as source protection and monitoring, and treatment such as micron filtration, ultra-violet disinfection, and ozonation. We utilize ozone instead of chlorine because it leaves no residual and it does not cause a taste or odor problem. Ozone is oxygen which is bubbled through water just before it goes into a clean, sanitized bottle. Within a few hours after the bottle has been filled and capped, the ozone dissipates or converts back to the same form of oxygen that we breathe.
