What we do:
The Biogeochemistry & Environmental Quality Research Group (BG&EQ) at Clemson University studies the budgets and chemistry of dissolved organic matter (DOM) in source water. We are particularly interested in understanding the influences of watershed perturbation and managements on DOM exports affecting downstream biogeochemical processes and drinking water quality. Specific analyses include optical properties, elemental composition, abundance of functional moieties, degradability, halogenated reactivity, and treatability in forming disinfection byproducts (DBPs). We have employed instrumental analyses such as fluorescence spectroscopy, pyrolysis gas-chromatography mass-spectrometry, Fourier Transform ion cyclotron resonance mass spectrometry, thermodynamic and kinetic calculations, controlled field and laboratory experiments, and watershed scale monitoring to study DOM dynamic in different water bodies under the influence of climate and land use changes.
