What are Trihalomethanes (TTHM)?

Trihalomethanes (TTHMs) are organic compounds that can form as byproducts during the disinfection of drinking water. They are typically produced when chlorine or other disinfectants react with naturally occurring organic matter present in the water supply. The presence of TTHMs in drinking water is significant since they are considered harmful pollutants linked to potential health risks, including cancer, when consumed over long periods.

Understanding their formation is crucial for water treatment facilities as regulatory bodies set limits on the permissible levels of TTHMs to ensure safe drinking water quality. Proper water management and treatment processes are therefore vital for controlling and reducing the levels of these byproducts.
