Chloramines are most commonly formed when ammonia is added to chlorine to treat drinking water. The most typical purpose of chloramines is to protect water quality as it moves through pipes. Chloramines provide long lasting protection as they do not break down quickly in water pipes. Chloramines of greatest regulatory interest are monochloramine, dichloramine, and trichloramine. If chloramines are used to disinfect drinking water, monochloramine is the most common type. Dichloramine and trichloramine are produced when treating drinking water but at much lower levels than monochloramine. Trichloramines are typically associated with disinfected water used in swimming pools. The Environmental Protection Agency regulates the safe use of chloramines. EPA requires water utilities to meet strict health standards when using chloramines to treat water. EPA chloramine regulations are based on the average concentrations of chloramines found in a water system over time. EPA regulates chemicals formed when chloramines react with natural organic matter in water. Additional Supporting Information The drinking water standard for chloramines is 4 parts per million (ppm) measured as an annual average. More information on water utility use of chloramines is available at HYPERLINK http//www.epa.gov/safewater/disinfection/index.html http//www.epa.gov/safewater/disinfection/index.html and in the 1997-1998 Information Collection Rule, a national survey of large drinking water utilities for the Stage 2 Disinfection Byproducts Rule (DBPR). Information on the Stage 2 DBPR is available at HYPERLINK http//www.epa.gov/safewater/disinfection/stage2/ http//www.epa.gov/safewater/disinfection/stage2/. Natural organic matter is a complex mixture of compounds formed as a result of the breakdown of animal and plant material in the environment source http//www.iwahq.org/templates/ld_templates/layout_633184.aspxObjectId661579.
