Selecting Disinfectants in a Security‐Conscious Environment: Six Utility Case Studies

This article presents an overview of six case studies documenting water utilities' methods and outcomes for selecting disinfection processes. These case studies illustrate the unique, site‐specific considerations that underlie achieving the goals and meeting the disinfection needs of each water system. A summary of the case studies was included in AWWA's written testimony to the Senate Committee on Environment and Public Works, submitted as part of a hearing on chemical security at drinking water utilities.
