Abstract To investigate the role of bromide ion concentration on formation and speciation of non-trihalomethanes (non-THMs) chlorination organic byproducts, a two block full factorial matrix was designed to statistically evaluate the influence of various parameters which are relevant to drinking water treatment. The first block used a high chlorine dose and the second block a low dose. The factorial design incorporated one factor (Br) at four levels and two factors (time, pH) at three levels for each block. The percent of total organic halogen (TOX) attributed to 9 haloacetic acids (HAAs), 4 THMs, 3 dihaloacetonitriles (DHANs) (each as a group) and individual THMs and HAAs were determined. Br in chlorinated humic acid solution was shown to shift the distribution of THMs, HAAs and DHANs to more brominated species. The percentage of TOX made up of total THMs plus total HAAs significantly increases with increasing pH and bromide concentration. THMs were the largest class of chlorination byproduct detected on a weight basis, and the HAAs were found to be the second largest portion of the TOX at high pH in drinking water.
