Understanding NSF 61: Lead Regulations in Safe Drinking Water Systems | ADEM Update 2013

This presentation covers the importance of NSF 61 standards in preventing lead leaching in public water systems following the ADEM regulation update. Learn about lead content standards, marking, and certification by ANSI, ensuring compliance with health effects criteria. Discover the scope of NSF/ANSI Standard 61 for various products including pipes, fittings, and valves. Understand the requirements for contaminant migration, formulation disclosure, and toxicology evaluation to maintain safe drinking water. For inquiries, contact Laura A. Taylor at (334) 271-7820 or lat@adem.state.al.us.

  2. Overview • Introduction to NSF • Lead Leaching • NSF 61 • Safe Drinking Water Act Revision • Lead Content Standards – NSF 61-G • NSF 372 • Marking

  3. NSF Standards Development Process

  4. OAC 3745-83-01 (D) • All chemicals, substances, and materials added to or brought in contact with water in or intended to be used in a public water system . . . and shall conform with (ANSI/NSF) standard 60 Drinking Water Treatment Chemicals – Health Effects (2005 and previous), or standard 61 Drinking Water System Components -Health Effects (2005 and previous). Any organization certified by the "American National Standards Institute" may certify in writing that a product conforms with these standards.

  5. Certification Marks

  6. NSF/ANSI Standard 61- Scope • Pipes and Related Products (pipe , hose, fittings) • Protective and Barrier Materials (cements/coatings) • Joining and Sealing Materials (gaskets, adhesives, lubricants, solvent cements) • Process Media (activated carbon, filter media) • Mechanical Devices (water meters, valves, filters) • Mechanical Plumbing Devices (faucets, drinking fountains, and components)

  7. Standard 61 Requirements 1. What contaminants migrate or extract into water? 2. Are they below maximum allowable level? • Formulation disclosure by manufacturer. • Formulation review of product. • Extract contaminants from product into water. • Analyze extraction water for contaminants. • Perform toxicology evaluation of contaminants
