Abstract: The water utility of the northwest Arkansas, the Beaver Water District is in the process of changing the pre-oxidant from free chlorine to chlorine dioxide in order to curb disinfection byproduct formation. The objective of the proposal is to identify the diversity of bacterial phyla that persists during the switch of pre-oxidant from chlorine to chlorine dioxide in Beaver Water District. The microbial community will be determined in both suspended and attached forms, and correlate these operational taxonomic units with controlling water quality parameters in order to lessen the occurrence of DBP formation. The results will help water utility make an informed decision when switching pre-oxidants.
