Pit-water from an Uranium (U) mine in San Rafael, Argentina, was applied to soil columns in a short-term experiment to evaluate retention of U. The mine soil was coarse-textured, with pH
(KCl)
7.7 and a carbonate content of 6%, which may favour the formation of uranyl-carbonates. Triple superphosphate (TSP) and ground plant material were added as amendments to reduce U mobility in soil. Plants were sown to study their effect on U leaching. > 99 % of the U applied was retained by the soil. Plant growth increased U mobility but also reduced leachate volumes through evapotranspiration. TSP increased plant biomass, reducing the mass of U leached, while ground plant material enhanced leaching of U.
