Chloramines are a type of combined chlorine that form in water and then off gas into the air above the water. Most city, county, and state health departments limit the amount of combined chlorine in the water to 0.4 ppm or less. Chloramines can build up in the water, which means they can build up in the air if there is not enough fresh air surrounding pools and other places people swim in chlorinated water .
The type of chloramine discussed on this page that is used to treat drinking water (monochloramine) is not the same type that can form and harm the indoor air quality around swimming pools (dichloramine or trichloramine) . Chlorine was first used as a drinking water disinfectant in Europe in the late 1800s. It was first used in the U.S. in 1908 in Jersey City, New Jersey . Chloramine has been used as a drinking water disinfectant in the U.S. in places like Cleveland, Ohio, Springfield, Illinois, and Lansing, Michigan since 1929 . Today, chlorine and chloramine are the major disinfectants used to disinfect public water systems.
