Adsorption of Metals to Geomedia II Symposium

The U.S. Geological Survey (USGS) and Auburn University are cosponsors of the "Adsorption of Metals to Geomedia II Symposium" at the 231st American Chemical Society (ACS) National Meeting, Atlanta, Georgia, March 26-30, 2006. Understanding of chemical reactions at mineral-water interfaces in natural systems has advanced at a rapid pace. The objective of the symposium is to highlight these advances, ranging from characterizing the structure and bonding of surface complexes to achieving quantitative predictions of the impact of mineral-water-interface reactions on metal-ion transport at the field scale. This meeting provides information that is relevant to the fate of toxic substances in the environment that can be used by policy makers, environmental regulators, water-resource managers, and contamination clean-up professionals to design cost effective programs.
