Natural 7.7pH Alkaline Spring Water ? Stream comes from a source originating thousands of years ago as the result of a receding glacier depositing a gravel esker that naturally filters our water today. Remaining undiscovered in the Highlands of Eastern Ontario until 1994, a local hydrologist, so impressed with the clarity and taste, investigated further to analyse and fully uncover the history, beneficial qualities and characteristics of this water. This fine, natural spring water is left in its pristine state, exhibiting mineral and organic qualities as an expression of the ice, rocks and earth from which it came. Stream. Naturally Perfect.
