Dr. Nason’s research group primarily focuses on the physical and chemical processes involved in water quality control. This work serves to promote a better understanding of the mechanisms involved in water treatment, and provides insight into decisions with respect to management and engineering design. Recently, this work has been divided into two distinct branches. The first deals with nanoparticle fate and transport, and the chemical and physical parameters that govern these processes. The other branch focuses on copper in stormwater runoff, with projects focusing on characterization of stormwater runoff, copper speciation, and copper removal using media filtration.
