Startups like Live Water in Oregon and Tourmaline Spring in Maine have emerged in the last few years to deliver untreated water on demand. What adherents share is a wariness of tap water, particularly the fluoride added to it and the lead pipes that some of it passes through.

They contend that the wrong kind of filtration removes beneficial minerals. Even traditional bottled spring water is treated with ultraviolet light or ozone gas and passed through filters to remove algae.
