The objective of this study was to explore methodologies for limiting the formation of haloacetic acids (HAAs) in North Carolina drinking water utilities so that they would be in compliance with the proposed maximum contaminant levels (MCLs) for both trihalomethanes (THMs) and HAAs. The two methodologies explored involved pH adjustment and chloramination. Both of these approaches are expected to be less costly and easier to implement than other options such as ozonation as an alternative to free chlorine, or granular activated carbon adsorbers or membrane separation processes, both of which enhance the removal of DBP precursors.
