What chloramine is
Chloramine is made from chlorine and ammonia.
“Chloramines are most commonly formed when ammonia is added to chlorine to treat drinking water.”
EPA says: EPA: Basic Information about Chloramines and Drinking Water DisinfectionWhy a utility might use it, in EPA's words:
“Chloramines provide longer-lasting disinfection as the water moves through pipes to consumers.”
EPA says: EPA: Basic Information about Chloramines and Drinking Water Disinfection“Many public water systems (PWSs) use chlorine as their primary disinfectant. However, some PWSs changed their secondary disinfectant to chloramines to meet disinfection byproduct requirements.”
EPA says: EPA: Chloramines in Drinking WaterPeople who keep fish or other aquatic animals, and people on dialysis, often ask about chloramine. CDC's page on water disinfection with chlorine and chloramine covers both topics: CDC: About Water Disinfection with Chlorine and Chloramine.
Not listed doesn't mean not used.
Not a complete list. Roughly a third of community water systems have no disinfectant record in these files, and states differ in what they report. Your utility's annual water quality report says which disinfectant it uses.
Each row means EPA records list chloramine for that system, as reported by the state. It doesn't describe every home in the place the system serves.
EPA SDWIS treatment records via Envirofacts, downloaded November 6, 2026. The data is state-reported.
