What is monochloramine (chloramine)?
Monochloramine is a chemical disinfectant used to treat drinking water. It is formed by mixing chlorine with ammonia. Although monochloramine is a weaker disinfectant than chlorine, it is more stable and extends disinfectant benefits throughout a water utility’s distribution system (a system of tanks and pipes used to deliver water to homes). Monochloramine also creates fewer of the regulated harmful disinfection byproducts than chlorine.
