Key Findings & Highlights

This section will contain publicly available key findings and highlights from published papers.

  • New Thermodynamic Model Predicts Plutonium Solubility with Iron
    A hard-to-detect but stable form of iron helps convert subsurface plutonium from barely to very soluble, according to scientists at Pacific Northwest National Laboratory and Rai Enviro-Chem, LLC.
  • Microbially Produced Ferrous Iron May Decrease Technetium Concentrations in Groundwater
    The long-lasting radionuclide technetium is transported through the subsurface near former nuclear production and processing sites, moving toward rivers and lakes.
  • Einstein Wasn't Always Right
    Around the nation, sediments and groundwater are contaminated with uranium from discharges at mining and processing sites, such as the U.S. Department of Energy's Hanford Site in southeast Washington State.
  • John Zachara Named Battelle Fellow
    Veteran geochemist John Zachara has been named a Battelle Fellow, a rank shared by only three other Pacific Northwest National Laboratory scientists. The honor recognizes Zachara, who's been at the Laboratory for 31 years, for his scientific accomplishments, leadership and long record of service as advisor to multiple Department of Energy offices.
  • Scientists Show How Bacteria Move Electrons Across a Membrane
    Scientists at the University of East Anglia, Pacific Northwest National Laboratory, and Pennsylvania State University have demonstrated for the first time the mechanism by which some bacteria can transfer electrons across a membrane to the cell exterior, allowing them to "breathe" metals.
  • Tim Scheibe Chosen Darcy Distinguished Lecturer
    Dr. Timothy D. (Tim) Scheibe has been selected as the 2010 Henry Darcy Distinguished Lecturer in Ground Water Science. Scheibe, a staff scientist at Pacific Northwest National Laboratory, was invited by the National Ground Water Research and Educational Foundation to spend next year lecturing at colleges and universities to educate and create interest in groundwater science and technology.
  • Where Did the Uranium Go?
    Uranium's migration through the soil depends on groundwater's chemical composition, according to a recent study by Pacific Northwest National Laboratory.
