In chemistry, trihalomethanes (THMs) are chemical compounds in which three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. Many trihalomethanes find uses in industry as solvents or refrigerants. THMs are also environmental pollutants, and many are considered carcinogenic. Trihalomethanes with all the same halogen atoms are called haloforms. WebWater systems add chlorine to drinking water to kill or inactivate harmful organisms in a process called “disinfection.”. During this process, chlorine also reacts with naturally occurring organic matter that may be present in drinking water. Chlorine disinfection byproducts (DBPs) can form during this chemical reaction.

For example, in general THM formation increases with an increase in pH but the effects are reversed for HAA5. Temperature has a positive effect on DBP formation potential, and increases the rate of reaction (Amy et al., 1987a; US EPA, 2001b). chuf freeman hospitalWebThe MTP determination maximizes the formation of THMs and indicates how high the TTHM concentration could be- come under conditions favoring TTHM formation.
