Abstract
Scientific interest has recently focused on the hydrophobic halogenated byproducts of drinking water disinfection with chlorine, principally chloroform and its sister trihalomethanes (THMs). There is, however, a growing body of literature indicating that THM formation cannot account for most of the total organic halide (TOX) produced from the aqueous chlorination of these precursor materials. Efforts have thus been made to identify and quantify the individual components of nonvolatile TOX in drinking water. Varieties of small aliphatic chlorinated hydrophilic compounds were determined to result from the chlorination of an extracted aquatic humic material under various reaction conditions. The dominant components found in each case were dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA).
