Book excerpt: Strontium distribution coefficients (Kd's) were measured for 24 basalt core samples collected from selected sites at the Idaho National Engineering and Environmental Laboratory (INEEL). The measurements were made to help assess the variability of strontium Kd's as part of an ongoing investigation of strontium transport properties through geologic materials at the INEEL. The investigation is being conducted by the U.S. Geological Survey and Idaho State University in cooperation with the U.S. Department of Energy. Batch experiments were used to measure Kd's of basalt core samples using an aqueous solution representative of wastewater in waste-disposal ponds at the INEEL. Calculated strontium Kd's of the 24 basalt core samples ranged from 3.6"1.3 to 29.4"1.6 milliliters per gram. These results indicate a narrow range of variability in the strontium sorptive capacities of basalt relative to those of the sedimentary materials at the INEEL. The narrow range of the basalt Kd's can be attributed to physical and chemical properties of the basalt, and to compositional changes in the equilibrated solutions after being mixed with the basalt. The small Kd's indicate that basalt is not a major contributor in preventing the movement of strontium-90 in solution.
