The United States Environmental Protection Agency notes that bottled water is not necessarily safer to drink than tap water. That's because the EPA sets the standards for drinking water provided by public water systems. While the responsibility of setting standards for bottled water falls on the shoulders of the Food and Drug Administration, the FDA sets the bottled water standards based on the tap water standards established by the EPA. According to the EPA, both bottled water and tap water are safe to drink if they meet these standards. However, the EPA does advise people with severely compromised immune systems and parents of children with special needs to consult physicians before deciding which type of water they drink or give to their children to drink.
