This article provides a brief discussion of inherently safer technologies (ISTs), which are standards for assessment of a utility's treatment methods. Evaluating changes to treatment processes requires a thorough consideration of the effects different alternatives will have on the quality of water provided to consumers and of the sustainability of the selected treatment process over time and under adverse conditions. The article also discusses a five‐step process published in 2009 by AWWA in a book titled, “Selecting Disinfectants in a Security‐Conscious Environment.” This process can be used by utilities to support their decision‐making process given competing priorities and risks. The steps are: assess the situation; identify options; evaluate options; select preferred option; and, implement.
