Haloacetic acids

Haloacetic acids are another class of common byproducts of water disinfection, including monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid and dibromoacetic acid. The human health effects have not been well documented, howeversome epidemiological studies suggest that HAA exposure during the second and third trimesters of pregnancy may be linked to birth defects in newborns. Exposure can be dramatically reduced with a filtration system.
