The information regarding the federal standards set by EPA
The bottlers must include the name of product, type of water, name and address of manufacturer, packer or distributor and net content on their labels. The new bottled water sources must be approved by state or local jurisdiction. They must test their sources and finished bottled water products at least once a week for microbiological contaminants and at least once a year for physical, chemical, and radiological contaminants.
If bottled water is found to be adulterated or hazardous to health, it is subject to FDA enforcement action, such as seizure of domestic products and refusal of entry of imports. Bottlers must exercise good manufacturing practices to ensure that their bottled water products are safe and produced under safe and sanitary conditions.
EPA helps to learn more about the quality of their drinking water, either tap water or bottled water. If your water comes from a public water system, the best way to learn more about tap water is to read your water supplier’s annual water quality report. If your water comes from a household well, EPA recommends testing the water regularly for bacteria, nitrates, and other contaminants.
The best way to learn more about bottled water is to read its label, or contact the producer directly. In addition to the volume of water, any pertinent nutritional claims, and any contact information for the bottler, the label may include the type of bottled water, its source, and the way in which it is treated.
