Organic and Isotope Geochemistry Group

800 600 Stroud Water Research Center

The complex mixture of organic molecules in streams and rivers holds clues about a wide variety of natural and human processes occurring within watersheds. By determining the identity and origin of these molecules, the scientists in the Organic and Isotope Geochemistry Group can both expand scientific understanding of natural cycles of energy (carbon) and nutrients within the ecosystem and inform decision-makers about the sources and impact of human contamination on water quality.
