Several bottled waters are sold as “alkaline,” meaning a pH above 7 (7 is neutral). This page summarizes what six brands say about their own water, based on each company’s website and, for Essentia, a Nestlé announcement. These are the brands’ own claims. This page does not test any water, rank the brands, or make health claims.
