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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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.

This standard describes epichlorohydrin dimethylamine (EPI–DMA) polyamines for use in the treatment of potable water, wastewater, and reclaimed water.

Major changes made to the standard in this revision include the following:
1. Requirement that suppliers provide product technical data sheets along with SDSs (aka MSDSs).
2. Requirement that product technical data sheets contain specific information.
3. Improved guidance on establishing purchasing specifications.
4. Inclusion of a requirement for tamper-evident packaging. (Sec. 6.2)
