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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 mined and manufactured manganese oxide filter media as used in pressure and gravity filters to remove iron, manganese, radium, arsenic, and hydrogen sulfide in potable water treatment applications. It discusses handling, preparation, placement, sampling, and testing requirements specific to manganese oxide filter media as well as the reporting responsibilities of the manganese oxide filter media manufacturer.

Users of this standard should refer to ANSI/AWWA B100 for basic requirements of placing filter media, preparing filters for service, replenishing media in existing filter beds, sampling and testing media, and packaging and shipping media.

MAJOR REVISIONS
This is the first edition of this standard.
