This NSF/ANSI/AWWA standard provides a framework for collecting data and communicating information on the sustainable attributes of a water treatment chemical product, whether repackaged, relabeled and/or distributed and can be from one or more facilities (locations). Such information is expected to encourage the demand for and supply of water treatment chemical processes that have a reduced impact on the environment and society, thereby stimulating the potential for market-driven continuous improvement.

This standard is intended to be science based, provide transparency, and offer credibility for manufacturers in making environmental claims and to harmonize the principles and procedures used to support such claims. It establishes a consistent approach to the evaluation and determination of environmentally preferable and sustainable chemical product manufacturing processes, water treatment chemical products, distributors, repackagers, and relabelers of chemical products. Many of these water treatment chemical products are used for public health protection. The document includes relevant criteria across the product(s) lifecycle from raw material extraction through manufacturing, use, and end-of-life management. The intended use of this Standard is to show that the product, manufacturing processes, distribution, repackaging/relabeling, and corporate practices of a water treatment chemical product manufacturer are more sustainable.
