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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 powdered activated carbon (PAC) for use in adsorption of impurities for water supply service applications.

MAJOR REVISIONS

Major revisions made to the standard in this revision include the following:

  1.  Threshold odor test was moved from the body of the standard to appendix B, Section B.3, removing it as a requirement of the standard.

  2.  Sec. II.C of the foreword was revised, and Sec. II.D was added.

  3. Options listed as “upon request of the purchaser” were changed to “When requested in the purchase document” to better define the option.

  4. Because of the variety of tannic acids commercially available, the purchaser is now encouraged to conduct the tannin value test in-house or through a reliable third-party laboratory to ensure uniformity of tannin values for each carbon sample submitted.

  5. Sections 6.1.2, 6.2.1, and 6.2.2: “plastic bags” added.

  6. Boilerplate language updated throughout the standard.
