Which standard must filter media meet according to the American Water Works Association?

The correct standard that filter media must meet according to the American Water Works Association is B100-96. This standard outlines the specifications for the materials used in filtration systems, ensuring they are effective and safe for use in drinking water treatment processes. Compliance with this standard helps to guarantee that the filter media performs adequately to remove contaminants, maintain flow rates, and produce high-quality treated water.

While the other standards listed, such as B100-92, B100-99, and B100-03, represent changes or updates to the specifications over different years, it is specifically B100-96 that is recognized for setting the criteria that must be adhered to when selecting filter media.
