Testing is continually conducted to ensure Icelandic Glacial Water meets top food safety and quality standards. Our facilities and products are fully accredited by the NSF and always meet or exceed U.S.A. Food & Drug Administration and World Health Organization requirements. Both the Ölfus Spring source and our facility are also regularly inspected by the Icelandic Public Health Authority, which carries out stringent tests to ensure the facility is operating in compliance with WHO standards. In addition to governmental requirements, Icelandic Glacial carries out extensive daily testing with its own in-house laboratory.
