Filtering material must conform to what standards?

Filtering material must conform to AWWA standards because the American Water Works Association (AWWA) establishes industry standards specifically tailored to water utility practices, including the quality and performance of materials used in water treatment and distribution. AWWA standards ensure that the filtering materials are effective, reliable, and safe for use in processes involving drinking water and wastewater treatment, which are critical for public health and environmental compliance.

While the other standards mentioned may apply in certain contexts, they do not specifically target the requirements for filtering materials in the same way that AWWA standards do. For example, EPA standards focus on the overall regulatory framework governing water quality and safety, ISO standards are more general global benchmarks for various processes, and ANSI standards pertain to consensus standards across a broad range of industries but may not specifically address filtering materials in water treatment as comprehensively as AWWA standards.
