This special focus issue of Journal AWWA presents papers from the United States and abroad that discuss current research on nitrosamines. This month's guest editor discusses how drinking water utilities have cost‐effectively optimized their treatment and disinfection processes to control a variety of micropollutants to meet state and federal regulations, operational requirements, and aesthetic issues. However, the discovery of new pollutants presents challenges to the drinking water industry. An emerging class of disinfection by‐products (DBPs) of health and regulatory concern are nitrosamines (e.g., N‐nitrosodimethylamine [NDMA]). NDMA is preferentially formed by chloramines, where chloramines have been increasingly used to control the formation of the regulated DBPs trihalomethanes and haloacetic acids.
