Research in the Arnold group focuses on the fate of organic chemicals in natural and engineered aquatic systems. Specific research areas include studying the kinetics, pathways and mechanisms of anthropogenic chemical reactions that occur at surfaces or via photochemical processes; evaluating mass transfer effects on reaction rates; developing new remediation/containment techniques; and using computational chemistry techniques to predict and/or explain experimental observations.
Our current efforts are focused on:
    -Redox reactions at metal and mineral surfaces
    -Photochemistry of pharmaceuticals in surface waters
    -Disinfection by-product degradation and formation
    -Reactive membrane systems
    -Sensor networks to monitor and predict stream water quality
