U.S. Drinking Water Authorities

• EPA Safe Drinking Water Act (1976) and Amendments
  (1986 and 1996).
• Minimum national requirements for drinking water
  quality and monitoring for public water
  systems.
• States-have primacy for compliance and
  enforcement of Safe Drinking Water Act.
• Carried out through state regulations.
• Cities/Municipal Districts-responsible for water
  quality and reporting functions for public water
  systems.

History Of Additives Regulation in the U.S.

• 1972 1990 EPA operated a listing
  program for treatment chemicals
• 1984 EPA issues Request For
  Proposal - Development of a
  health effects standards -
  Development of a certification and
  monitoring program

5
History Of Additives Regulation in the U.S.
(continued)

• 1985 EPA awards contract to NSF lead
  consortium
• NSF International (principal)
• Association of State Drinking Water
  Administrators (ASDWA)
• American Water Works Association (AWWA)
• AWWA Research Foundation (AWWARF)
• Conference of State Health and Environmental
  Managers (COSHEM)

6
History Of Additives Regulation in the US
(continued)

• 1988 NSF Standards 60/61 are completed and
  certification begins.
• 1989 NSF Standards 60/61 are approved by ANSI.
  NSF Certification Program is accredited by
  ANSI.
• 1990 EPA terminates its Listing advisory
  program.
• 2003 More than 85 of U.S. states require product
  certification to NSF/ANSI Standards 60/61.

7
State Compliance 2003

• ASDWA Survey Conducted late 2002
• Most states now reference Standards 60 and 61
• 46 states have legislation/regulations/policy
• 40 states require ANSI accredited certifiers
• The number of states which require certification
  continues to increase

8
NSF/ANSI Standard 60 Requirements

• 1. Is the Chemical safe at its maximum use?
• 2. Are contaminants below maximum allowable
  levels?
• Formulation Disclosure by Manufacturer
• Formulation Review of Product
• Analytically Test at 10x Maximum Use
• Analyze for Contaminants
• Toxicology Evaluation of Chemical and Contaminants

Certification Benefits

• Simplified and unified requirements
• Signifies testing and evaluation by NSF
• Eliminates need for multiple testing requirements
• Adds credibility in marketplace
• Meets water utility requirements
• Frees regulators of certification burdens
• Basis for regulatory acceptance
• Evaluates products to most current regulatory
  requirements, as regulations change
• Reduces costs!
