	Water Quality Association Chloramine - Are there negative health effects?
		Chloramine is formed as a result of the reaction between applied chlorine and ammonia present in the natural water or ammonia that has been added to react with chlorine so that a combined chlorine (chloramine) residual will be formed.
		Chloramine is used principally in systems requiring a reduction in tastes and odors, or a reduction in disinfection byproducts, such as trihalomethanes (THMs).
		In water systems that use chloramine as the principal disinfectant, ammonia is added at a point downstream from the initial chlorine application so that microorganisms, including viruses, will be exposed to the free chlorine for a short period before the chloramine is formed.

	Chloramine - Wikipedia, the free encyclopedia
		Chloramine (monochloramine) is chemical compound with the formula NH Cl. Although it is important, NH Cl is invariably used as very dilute solutions where it is used as disinfectant.
		Aquarium owners must remove the chloramine from their tap water because it is toxic to fish.
		Chloramine must also be removed from the water prior to use in kidney dialysis machines, as it would come in contact with the bloodstream across a permeable membrane.

	Glossary: Chloramine
		A class of organic amines, chloramines are produced when ammonia and chlorine (as hypochlorous acid) react with each other.
		Chloramine is increasingly used in water treatment plants rather than chlorine, as chloramine is much more stable and will not dissipate from water, ensuring disinfection until it reaches the consumers.
		In chlorine water treatment, a combination of inorganic chloramines is formed as disinfection by-products, also referred to as combined chlorine residuals.

		Although chloramines are not as effective as disinfectants, compared to chlorine gas or sodium hypochlorite, they are less prone to form THMs or haloacetic acids.
		It is possible to convert chlorine to chloramine by adding ammonia to the water along with the chlorine: The chlorine and ammonia react to form chloramine.
		Water distribution systems disinfected with chloramines may experience nitrification, wherein ammonia is used a nitrogen source for bacterial growth, with nitrates being generated as a byproduct.
