Geochemical Analysis of Lake Sediment Funded by Illinois Environmental Protection Agency
Andrew Stumpf received funding from the Illinois Environmental Protection Agency through their Lake Education Assistance Program. The project goal is to analyze additional samples from lake cores collected by the U.S. Geological Survey Hoverprobe in 2000. To date, 40 samples from three separate cores have been analyzed, and preliminary results indicate a complex geochemistry, both naturally occurring and anthropogenic induced. Up to 15 additional core samples will be submitted to Activation Laboratories Limited in Ancaster, Ontario, Canada, for analyses of 35 oxides and for trace and rare earth elements. These results should help clarify the earlier results.
