Meeting or Exceeding Regulatory Requirements
In the U.S., municipal water supplies are regulated by the U.S. Environmental Protection Agency (EPA) under The Safe Drinking Water Act and the bottled water industry is regulated as a food product by the FDA under the Bottled Water Regulations (which dictate water quality standards) and under the Current Good Manufacturing Practices (which dictate standards for the processing and manufacture of bottled water). The Safe Drinking Water Act also requires that bottled water meets all of the requirements of municipal water supplies. Together, these regulations mandate the testing of over 50 constituents at specified intervals to ensure that bottled water meets these standards.
In light of these regulations, Nestlé Waters has developed internal standards based upon both sets of regulations, which meet or are more stringent than regulatory standards in all cases. We test our finished product for every constituent required by the EPA and FDA, and our allowable limits for regulated parameters are more stringent than both EPA Primary Standards and FDA Standards of Quality guidelines. The only exception is for radiological parameters, where we use the same regulatory standards. Our standards also meet individual state regulations, as well as Canadian regulatory requirements, which are almost identical to those in the U.S.
On a per–gallon basis, we test our water as often as, or more often than, municipal water sources. For example, in the case of coliform, an indicator of contamination, we conduct one test for every 40,000 gallons of water. By comparison, a large municipal supplier conducts one test for every 2.7 million gallons of water processed. In many cases, we also test our water on a frequency basis as often as, or more regularly than, required by the EPA and FDA. For example, we test for bromate daily on every production line in every factory, whereas municipal water suppliers are only required to test monthly.
On an annual basis, there are a few instances where we test less frequently than municipal water suppliers, because our sources are not prone to the same types of contamination as some municipal water sources. In these cases, we still meet reporting requirements of the EPA and FDA. In addition, we use a multi-barrier process, which includes additional safety steps beyond those typically performed by municipal water suppliers, including microfiltration, ultraviolet light and, where appropriate, ozonation. These further protect our products from contamination. Learn more about our testing standards.
