NSF/ANSI Standard 60: Drinking Water Treatment Chemicals – Health Effects

As part of our public health mission, we’re making the 2016 version of the NSF/ANSI 60 standard available for educational purposes.

NSF/ANSI 60: Drinking Water Treatment Chemicals – Health Effects is an American National Standard that establishes the minimum health-effects requirements for the chemicals, chemical contaminants and impurities that are directly added to drinking water from drinking water treatment chemicals. This standard does not establish performance or taste and odor requirements for drinking water treatment chemicals.

Chemicals within the scope of this standard include but aren’t limited to:

  • Corrosion and scale inhibitors
  • Coagulants and flocculants
  • Disinfection and oxidation chemicals
  • Well-drilling aids
  • pH adjustment, softening, precipitation and sequestering chemicals
  • All other specialty chemicals used in drinking water treatment

The standard is routinely monitored and updated by a joint committee comprised of equal parts public health experts, end users and industry members. Click the link below to view the 2016 edition of this standard in full for free. The newest edition of the standard, which includes any updates since the 2016 edition, is available for purchase at the NSF Standards Store.

Members of the regulatory or public health community can receive free copies of the standard by contacting our regulatory affairs team.
