Bromodichloromethane

Bromodichloromethane is a byproduct formed when chlorine disinfectants react with organic matter in water. It's found in chlorinated tap water and may increase cancer risk.

Bromodichloromethane is one of several trihalomethanes (THMs) created when chlorine-based disinfectants react with organic matter in water. This colorless, sweet-smelling liquid is not naturally present in water sources but forms during the treatment process. The EPA regulates it as part of total THMs, measured in parts per billion (ppb). While health concerns exist, ongoing research aims to better understand its effects. Water utilities work to balance disinfection needs with minimizing THM formation.
