Impact of Halides on DBPs

Halide concentrations affect the quality of drinking water in downstream drinking water treatment plants by shifting the profile of disinfection by-product (DBPs) formation towards more toxic brominated and iodinated compounds. By studying the formation of DBPs in impacted drinking water systems, Dr. Parker seeks to understand how the halide concentrations of water sources alters drinking water quality.
