Seminar Abstract

Environmental Engineer Jim Szecsody and Earth Scientist Hilary Emerson share insights gathered from uranium characterization and remediation efforts at the Hanford Site in Washington and at the Rifle Mill Site in Colorado. “Implications of Uranium Behavior in the Subsurface for Environmental Remediation” was presented on June 18, 2020, as part of PNNL’s Center for the Remediation of Complex Sites (RemPlex) Seminar Series.
