Chlorodibromoacetic 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.

Chlorodibromoacetic acid forms when chlorine disinfectants react with naturally occurring organic matter in water. It's one of many haloacetic acids monitored in drinking water systems. Detection typically involves gas chromatography-mass spectrometry. While present in most chlorinated water supplies, levels vary based on source water quality and treatment methods. The EPA regulates it as part of a group of disinfection byproducts. Research suggests potential health risks from long-term exposure, prompting ongoing study and regulatory review.
