Cormac Hayden has spent his career picking apart the marketing behind bottled water, and the picture he paints is more complicated than a label suggests. He joined Sean Kelly on the Digital Social Hour to talk about how his company, Oasis, rates water quality and what most consumers get wrong about the water they drink.
The conversation moves from the sourcing behind popular bottled water brands to the contaminants Hayden says show up in surprising places, including sparkling water and energy drinks. It is a practical, sometimes surprising breakdown of an industry that rarely gets this level of scrutiny.
