(PhysOrg.com) -- Uranium's migration through the soil depends on groundwater's chemical composition, according to a recent study by Pacific Northwest National Laboratory. Scientists showed that uraniumattached to soil particles and moved slowly when the groundwater was at neutral pH and contained low levels of carbonate ion or dissolved carbon dioxide. Such conditions often occur at riverbanks when the river water rises and mixes with the groundwater. This work appeared in the September 1 issue of Environmental Science & Technology.
