A process for neutralizing chloramines, chlorine and ammonia in marine and fresh waters by adding an alkali metal formaldehydebisulfite in a dry or solution form in which the alkali metal formaldehydebisulfite is selected from the group consisting of sodium formaldehydebisulfite and potassium formaldehydebisulfite. Preferably, the alkali metal formaldehydebisulfite is sodium formaldehydebisulfite added in the amount at least equal to the greater of the quantity required to react on a one to one molecular basis with 4 times the stoichiometric amount of ammonia, 12 times the stoichiometric amount of monochloramine, 10 times the stoichiometric amount of dichloramine or 12 times the stoichiometric amount of chlorine in the form of hypochlorites present in the water to be treated.
