RoC Review of Haloacetic Acids Found as Water Disinfection By-Products
Primary Uses or Exposures
- Derivatives of acetic acid with one or more halogen atoms (i.e., chlorine or bromine) attached that are formed during chlorination of water containing organic molecules.
- People are mainly exposed to HAA from ingestion of chlorinated drinking water; they may also be exposed to HAAs from bathing or the use of swimming pools and spas that use chlorine for disinfection.
- More than 250 million people receive disinfected water, with 98% of water treatment systems using some type of chlorine disinfection process. Water disinfection is among the most important and beneficial public health advances of the 20th century in the United States and worldwide.
