Bromodichloroacetic acid is a disinfection byproduct formed when chlorine reacts with organic matter in water. It's found in chlorinated drinking water and may increase cancer risk.

Bromodichloroacetic acid forms when chlorine, used to disinfect drinking water, reacts with naturally occurring organic matter. It belongs to a group of compounds called haloacetic acids. While chlorination is crucial for eliminating harmful pathogens, it can create these unintended byproducts. Water treatment facilities monitor levels of disinfection byproducts, including bromodichloroacetic acid, to ensure they remain below regulatory limits. Reducing organic matter in water sources before treatment can help minimize the formation of these compounds.
