A recent survey shows that 64% of bottled water in the U.S. comes from the same municipal sources as tap water. Many brands don’t purify it significantly, and some even exceed contamination limits, raising concerns about value and safety.

Brands like Sam’s Choice and Acadia have been called out for “high contamination levels” that sometimes exceed California’s standards. Meanwhile, Gerber Pure, Nestlé Pure Life, and Penta Ultra-Purified Water are praised for their transparency about water sources and purification.
