Trihalomethane

THMs are chemical compounds in which three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. They are environmental pollutants and are known to be carcinogenic. Disinfection of drinking water with chlorine can cause the formation of THM if organic matter (THM precursors) is present. See also DBPs.
