The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal – American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal – American Water Works Association.

SCOPE
This standard describes ion exchange (IX) resin for water supply service applications and the requirements of the equipment used in water treatment to remove contaminants such as per and polyfluoroalkyl substances (PFAS), perchlorate, hexavalent chromium, uranium, and radium, etc., for potable water treatment applications with single-use ion exchange resin (resin that is not regenerated nor fluidized bed.) It discusses the design of ion exchange resin systems and requirements for the ion exchange material.
This standard is not intended to cover all media that work for listed contaminants, only ion exchange resin. This standard does not cover ion exchange resins that are regenerated on site.

MAJOR REVISIONS
This is the first edition of this standard.
