Note: this version has been superseded by version 3.0: Trost, J.J., Krall, A.L., Baedecker, M., Cozzarelli, I.M., Herkelrath, W.N., Jaeschke, J.B., Delin, G.N., Berg, A.M., and Bekins, B.A., 2020, Data Sets from the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA (ver. 3.0, March 2020): U.S. Geological Survey data release, https://doi.org/10.5066/P9FJ8I0P. This U.S. Geological Survey (USGS) Data Release provides analytical data from samples and measurements completed at the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota (Site) between 1984 and 2010. Included are inorganic and organic chemistry data from water, oil, and...
Toxic contaminants and naturally occurring substances found in the subsurface can exist in multiple phases, and undergo complex reactions including biodegradation. A comprehensive and quantitative understanding of the processes controlling the fate and transport of subsurface contaminants is necessary to develop policies and strategies for managing water-quality conditions in different land use and environmental settings. Numerical models that simulate flow, transport, and reactions are useful tools for understanding the fate of chemicals in the subsurface when used in conjunction with field and laboratory studies. The research efforts of this project consider flow and chemical behavior in the saturated and unsaturated...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
