Professor Benoit’s research and teaching focus on the behavior, transport, and fate of chemicals in natural waters, soils, sediments, and biota. Two special areas of interest are nonpoint source pollutants and biogeochemistry of trace metals and radionuclides. Most of his research involves state-of-the-art analytical methods and carefully designed field sampling programs, with results verified by laboratory simulations or simple mathematical models. His research is conducted in a watershed context, and study sites include freshwater and terrestrial systems, as well as estuarine and coastal environments. Four current research emphases are the use of modern clean techniques to investigate trace metals; micronutrient limitation by Cu and Fe; spatial and temporal variability of nonpoint source pollution; and human-environment interactions in urban areas.
