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 Therefore, these copies are not suitable for continued utilization and intended only for comment purposes.

Final publication of the standards may take several months. When they are 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.
