Bottled Water Production
All bottled water products - whether from groundwater or public water sources - are produced utilizing a multi-barrier approach.
From source to finished product, a multi-barrier approach helps prevent possible harmful contamination to the finished product as well as storage, production, and transportation equipment. Many of the steps in a multi-barrier system are effective in safeguarding bottled water from microbiological and other contamination.
Measures in a multi-barrier approach may include one or more of the following: Source Protection, Source Monitoring, Reverse Osmosis, Distillation, Micro-Filtration, Carbon Filtration, Ozonation, Ultraviolet (UV) Light.
BOTTLED WATER IS HIGHLY REGULATED
Bottled water is comprehensively regulated by the U.S. Food and Drug Administration (FDA) as a packaged food product and it provides a consistently safe and reliable source of drinking water. Tap water is regulated by the U.S. Environmental Protection Agency (EPA). By federal law, the FDA regulations governing the safety and quality of bottled water are as stringent as the EPA standards for tap water. And, in some very important cases like lead, bottled water regulations are substantially more stringent.

On a gallon-for-gallon basis, bottled water is tested up to 36 times more frequently than tap water for nearly all of the same contaminants.
With regard to daily testing, there are subtle differences between testing at a bottled water plant and a public water system (PWS) treatment plant. Bottled water facilities use waters from protected underground sources such as springs or artesian aquifers as well as from public water systems. Both bottled water and PWS plants typically test more frequently than the minimum number of samples required each month by respective FDA and EPA regulations, often on an hourly basis.
