Look for the mark and you'll find a safer product.
NSF International has been testing bottled water products for compliance with federal guidelines for many years. The NSF Bottled Water Certification Program is an annual, voluntary certification process that includes both extensive product evaluations as well as on-site audits of bottling facilities.
Our testing program provides for annual unannounced plant inspections covering every aspect of a bottler's operation, from the source of the water, through the disinfection and treatment process, and including the container closure process. We also perform extensive product testing for over 160 chemical, inorganic, radiological, and microbiological contaminants.
For a complete list of NSF-certified bottled water products, please visit our bottled water online product database. If you would like further information about a particular brand or would like to receive a copy of the individual test report, feel free to contact the bottler at the address or telephone number shown.
