Welcome to the Aquatic Chemistry Laboratory at WUSTL

Research in the Aquatic Chemistry Laboratory investigates chemical reactions affecting the fate and transport of heavy metals, radionuclides, and other inorganic contaminants in natural and engineered aquatic systems. Specific topics include reactions at the solid-water interface, drinking water treatment, contaminated site remediation, energy byproducts in the environment, biogeochemistry of metals in soils and sediments, and carbon sequestration.
