  1. Combining NSF/ANSI Standards 60/61 Annex D and Annex E

  2. Introduction • Drinking water pass/fail criteria in NSF/ANSI Standards 60/61 are currently located in two separate annexes • Annex D (normative) and Annex E (informative) • In each annex, there are multiple tables (D1-D4 and E1-E2) • As the annexes are currently maintained separately for Standard 60 and Standard 61, pass/fail criteria for chemicals may be listed in one Standard but not the other and duplicative entries are more challenging to identify • Maintaining multiple tables in two Standards makes it difficult for users to locate pass/fail criteria

  3. Recommendations • Consolidate the drinking water criteria currently in Annex D and Annex E into a single annex • Combined annex would be identical and appear in NSF/ANSI Standard 60 and Standard 61 • Recommendation is supported the Joint Peer Review Steering Committee (JPRSC)

  4. Joint Peer Review Steering Committee • Established to consolidate efforts among ANSI accredited certification bodies to prioritize risk assessments for review by the HAB and reconcile action levels derived from duplicate risk assessment efforts • Membership includes HAB chair and representatives from five certification bodies • Officially reached agreement to harmonize efforts in April 2013

  5. Joint Peer Review Steering Committee Why establish the JPRSC? • Reconciliation of Action Levels • Significant differences found in pass/fail criteria between certifiers • Differences may arise based on the time assessment was created • Differences may arise based on interpretation of toxicology data • >2000 chemicals currently being reviewed • Increased transparency of assessment process • Reduced liability for clients

  6. Normative/Informative • Currently, NSF/ANSI Standards 60/61 distinguish between normative and informative pass/fail criteria • Normative Criteria • Under Annex D, pass/fail values listed are to be used in the determination of product compliance with the Standard • Informative Criteria • Under Annex E, a chemical that exceeds the informative criteria should be subject to a complete toxicity data review and risk assessment prior to using the informational evaluation criteria to determine compliance with the Standard • A consensus among the JPRSC membership was that no distinction is currently made between normative and informative values when evaluating compliance

  7. Addition/updates of pass/fail criteria

  8. New Pass/Fail Criteria • Based on reconciliation efforts and development of new risk assessments, NSF International, along with the remainder of the JPRSC membership, is recommending the addition (or update) of 541 pass/fail criteria to Annex D/E of both Standards

  9. Sources of New Criteria • NSF International – Peer Reviewed Risk Assessments • Peer reviewed in 2012 or 2013 by the Health Advisory Board • NSF International – Threshold of Evaluation Chemicals • JPRSC – Initial List of Reconciled Values • JPRSC – Threshold of Evaluation Chemicals

  10. Questions • How could the DWA JC and DWTU JC effectively bridge conversations related to action levels? • Should action levels be pulled out of standards into separate standard? • If pulled out, what does oversight look like? New JC? Combined JC? • Others?
