Haloacetic acids or HAAs are carboxylic acids in which one or more halogen atoms take the place of hydrogen atoms in the methyl group of acetic acid. Those acids have a general chemical formula X1X2X3C−CO2H, where X is hydrogen or halogen, and at least one X is a halogen. In a monohaloacetic acid (XCH2−CO2H), a single halogen replaces a hydrogen atom: for example, in bromoacetic acid (BrCH2−CO2H). Further substitution of hydrogen atoms with halogens can occur, as in dichloroacetic acid (Cl2CH−CO2H) and trichloroacetic acid (Cl3C−CO2H).
Haloacetic acids are a common contaminant in treated drinking water, particularly water subjected to chlorination.
