Movement of Uranium Contamination in Ground Water

Uranium’s Mobility May Have Been Overestimated

Uranium contamination may move much slower in groundwater than previously believed, according to scientists at Pacific Northwest National Laboratory. Around the nation, sediments and groundwater are contaminated with uranium from discharges at mining and processing sites.

Knowing how uranium spreads out or diffuses in water is critical to predicting its movement and removing the contamination. But previous estimates may have significantly overestimated the radionuclide’s ability to move with the groundwater. Read more
