Technologies and Approaches to Minimize Brominated and Iodinated DBPs in Distribution Systems

Bromide and iodide in drinking water may increase health risks to consumers by promoting the formation of emerging brominated and/or iodinated disinfection byproducts (DBPs). Because regulation of these DBPs may be on the horizon, this project seeks to develop creative, novel, practical, and cost-effective techniques and approaches to minimize the formation of emerging brominated and iodinated DBPs in the distribution system. The project team will investigate strategies for precursor control via ion exchange and granular activated carbon (GAC) adsorption, optimization of pre-oxidation strategies, and localized treatment in the distribution system (i.e., GAC, biological activated carbon, and ultraviolet photolysis).
