GENERAL INFORMATION-FORMS `; WHO IS tiSFl uNSF.International (NSF) is an independent, not-for-profit orgarazatioh'of scientists, engineers, technicians, educators, <and analysts. -It is a trusted neutral agency, serving government,;industty^arii'cdnsumeis in achieving solutions to problems relating to public health and the environment since 1944. The mission jbfJNSF is to provide clients and the general public with abjective, high quality, timely, third-party services at acceptable cost; Services include development of consensus standards, voluntary product testing and certification with policies ami practices which protect the integrity of registered Marks, education and training, and research and demonstration, all relating to public health^and the environmental sciences. -J'Y' . . . -f - WHAT IS THE DRINKING WATER ADDITIVES PROGRAM? ANSI/NSF^Standard 60 (Drinking Water Treatment Chemicals - Health-Effects) and ANSI/NSF Standard 61 (Drinking Water System'Gqmponents - Health Effects) are voluntary consensus standards^developed by regulators, industry, and product users and.specifiers tmder the guidance of NSF and its consensus standardsproicess. Standard 61 addresses two aspects: (1) Do contaminants leachor migrate from the material into the drinking water, and (2) If so, is the level of migration acceptable from a public-health viewpoint? Standard 60 addresses direct treatment chemicals and their contaminants and if the levels of these cherrticals are acceptable from a public Health viewpoint NSF's Drinking Water Additives program is a third-party Certification which includes auditing, sampling, testing, . toxicology review, arid evaluation relating to the potential health effects of drinking water products/materials, in accordance with the criteria established'in Standards 60/61. ''T HOW DOES THE PROCESS WORK? The first step toward Certification under'NSF Standard 61 requires the Applicant to complete a Product/Materials Information Form (P/MI). After die form is reviewed byNSF.the Applicant is provided widi one Toxicology Data Review Submission Form A (TDRS-A), for each material determined to be in contact with drinking water. The Applicant must either complete this form (if the Applicant manufactures the material) OR, forward the form to the appropriate Material Supplier (if the Applicant merely assembles or repackages the material). The first step towards Certification under NSF Standard 60 requires the Applicant to complete a Toxicology Data SubmissionForm A (TDRS-A). As the TDRS-A forms are received at NSF, a toxicologist will identify ingredients in the material which require additional information. A TDRS-B form will then be prepared for each ingredient and forwarded to tire Material Supplier who, in turn, forwards die forms to the appropriate Ingredient Suppliers for completion. Once all of the TDRS forms have beat returned, a Formulation Review is conducted by authorized NSF chemists and toxicologists to determine which analytical tests are necessary to evaluate the Applicant's product During the selection of the testing protocol for potential contaminants, consideration is given to the degree of toxicological concern as well as the economic and practical' limitations of die analytical tests within the constraints of die Standard. Measured contaminant concentrations are normalized to reflect the levels anticipated "at die tap." Regulated contaminants (those which have a Maximum Contaminant Level set by the USEPA) do not requirfe further toxicology evaluation. However, establishing Maximum Allowable Levels for nonregulated contaminants will require additional toxicology review data, either from new toxicology studies initiated at the time of the testing or previously completed and defensible studies. Should additional toxicology data be necessary, NSF toxicologists will work with the Applicant to determine whether or not previous studies or literature sources fulfill the requirements of Standards 60/61. CONFIDENTIALITY: Only personnel authorized by NSF shall be allowed to review form A and B Applicant and Supplier information, which shall be secured according to NSF Confidential Information Security Procedures. Proprietary information will not be revealed or provided to Applicants or their Suppliers or third parties unless there is prior notarized written approval. However, the sharing of toxicological information between companies is encouraged where such sharing may expedite product certification.
