Resources: Drinking Water and Your Health

With tap water safe and abundant in the United States, Peter H. Gleick looks at why so many Americans drink their water from plastic bottles -- many of which end up in massive landfills.

Gleick dropped by "Good Morning America" today to talk about his new book, "Bottled & Sold," and the big business of the bottled water industry.

In the book, Gleick argues that bottled water companies have waged an advertising campaign against tap water, implying it to be unpure and, therefore, unsafe.
