Chloramines are an alternative disinfectant to chlorine. Specifically, chloramines are a blend of chlorine and ammonia that has been shown to greatly reduce the disinfection by-products caused by chlorination. There are different forms of chloramine: mono-chloramine, di-chloramine, trichloramine and organic chloramines. The city water treatment plant uses only mono-chloramine. We recommend asking your local water utility if they use chloramine in the water or have your water tested. For more information on chloramine, go to the EPA website.
