Environmental contaminants specialist John Weber, of the Columbia Ecological Services Field Office, had the opportunity to perform critical environmental research at the Department of Energy's Argonne National Laboratory, Advanced Photon Source.
The Advanced Photon Source is a national synchrotron facility and is one of the most technologically complex machines in the world. This premier national research facility provides the brightest x-ray beams in the Western Hemisphere and is used by a wide spectrum of scientists in a variety of disciplines from around the globe.
Mr. Weber’s investigation focused on the analysis of lead (Pb) contaminated floodplain soils originating from a historic mining district surrounding the Big River of southeast Missouri. As a part of a multi-million dollar restoration effort under the Natural Resource Damage Assessment and Restoration program, the U.S. Fish and Wildlife Service and our state partners are actively engaged in the development of environmentally sound restoration technologies. The restoration projects could then be implemented in southeast Missouri to reduce the toxicity of lead-contaminated soils. Analytical work at the Advanced Photon Source was used to confirm the formation of low bioavailability lead and phosphorus compounds. In conjunction with scientists from the U.S. Environmental Protection Agency and the University of Missouri, Mr. Weber was able to document the formation of the lead and phosphorus compounds, which is a critical step in the selection of the most appropriate restoration technologies. As the restoration science is developed, the Service and our state partners will select and implement the most environmentally sustainable projects that serve to restore and replace the injured natural resources of southeast Missouri.
