The granite bedrock of the Ouachita Mountains region in Arkansas provides the perfect filter to produce a water of impressive purity that is also delightfully refreshing. Mountain Valley Spring Water is the result of a 3,500-year journey by melting snow and falling rain to the heart of a deep, stone-lined aquifer. The resulting exemplary bottled water has been enjoyed since 1871, when the Greene brothers first realized their sweet, fresh product could provide a healthy alternative source of hydration for a wider audience. "Taking the waters," as it was then known, was a fashionable trend in which people believed certain springs produced a healthful mix of natural, mineral-infused water. Today, scientific analysis shows the exact ratio of minerals and how they can help to replenish the body's store of nutrients, but it's this complex blend that also gives Mountain Valley its crisp, sweet taste, the true source of its popularity.
