Implications of Uranium Behavior in the Subsurface for Environmental Remediation will be presented Thursday, June 18, by environmental engineer Jim Szecsody and Earth scientist Hilary Emerson as part of the Center for the Remediation of Complex Sites (RemPlex) Seminar Series.

The RemPlex seminar starts at 12:30 p.m. PDT via Zoom (Meeting ID: 923 1347 7385) and is open to the public.

Uranium contamination persists in the subsurface above regulatory limits due to both natural and anthropogenic sources. Subsurface remediation of uranium is challenging, however, due to the interactions of uranium and waste co-contaminants in the subsurface including sorption, precipitation, complexation, and redox processes. Szecsody and Emerson will present insights gathered from uranium characterization and remediation efforts at the Hanford Site in Washington and at the Rifle Mill Site in Colorado.

RemPlex is a new PNNL platform created by EED’s Earth Systems Science Division and Environmental Management sector. RemPlex couples unique core competencies and expertise with state-of-the-art facilities and physical assets to develop, mature, and deploy advanced technologies to solve complex issues of contaminated subsurface environments.
