Haloacetic acids

Definition:

A family of organic compounds based on the acetic acid molecule (CH3COOH) where one or more hydrogen atoms attached to carbon atoms are replaced by a halogen (chlorine, bromine, fluorine and/or iodine). There are nine species of HAAs including monochloroacetic acid (MCAA), dichloroacetic acid (DCAA), and dibromoacetic acid (DBAA). HAAs are colourless, have a low volatility, dissolve easily in water and are fairly stable.

They can be present in chlorinated drinking water as chlorinated water disinfectant byproduct formed when the chlorine reacts with natural organic matter and/or bromide ions in raw water supplies. Other sources of haloacetic acids in the environment include waste water from chemical and pharmaceutical manufacturing processes, and industrial cooling water. The term 'Total Haloacetic Acids' (THAAs) refers to the sum of the concentrations of dichloroacetic acid, trichloroacetic acid, monochloroacetic acid, monobromoacetic acid and dibromoacetic acid in a water sample.
