Rising naturally from a spring in the Ouachita mountains, Mountain Valley spring water filters through granite-based aquifers collecting all the goodness from the land. Their water is sodium-and flouride-free with a naturally high, detoxifying 7.8 pH and rich blend of calcium, magnesium and potassium. Mountain Valley is only slightly lower than normal water in terms of deuterium, with 146 ppm D2O. Normal water has about 150 ppm of deuterium.
