Abstract: Expanding water demands in Arizona have put increasing pressure on city officials and scientists to develop innovative ideas to conserve dwindling water supplies. Reclaimed water is a viable option. However, because of the high iodide concentration in wastewater, there are concerns that iodide will not be removed during infiltration processes of groundwater recharge. The formation of iodinated disinfection by-products (DBPs) is a concern as iodinated DBPs are more toxic than their chlorinated or brominated analogues. The purpose of this study is to determine if iodinated DBP formation will be more problematic during indirect water reuse due to the treatment of groundwater under the influence of wastewater effluent.
