This powerpoint presentation begins by presenting background information on the bromate mitigation project, including: plant operation prior to study; bromate formation; and, an initial study done in 2006-2007. Bromate mitigation objective included: demonstrate Bromate Mitigation Strategies atfull-scale level; pH depression via CO<sub>2</sub> addition; and,Cl<sub>2</sub>/NH<sub>3</sub> addition. The Bromate Mitigation Testing Layout is presented, along with demonstration testing, preliminary CO<sub>2</sub> data analysis CO<sub>2</sub> testing results (pH = 7.2) and (O3/TOC = 1.0), CO<sub>2</sub> dosing, observations of CO<sub>2</sub> testing, Cl<sub>2</sub>/NH<sub>3</sub> additional testing, status and results (bench-scale), and TTHM formation (Bench-Scale). Includes figures.
