Health risks and benefits of bottled water.

Health and safety concerns have dramatically increased the consumption of bottled water in developed countries, including the United States. The economic and environmental impact of the many different bottled water products on the market is considerable, and the role and impact of bottled water for routine use is unclear, outside the setting of emergencies or natural disasters, when routine water sources may be unsafe. Evidence for routine health risks or benefits from using bottled water is limited. Patients who have specific health needs may wish to use bottled or filtered water. Physicians can use background information regarding the regulation, production, and possible health impact of bottled water to counsel patients.
