The objective of this study was to quantify 129I desorption of six waste materials in acidic and alkaline environments, simulating trench and cementitious disposal conditions. These data will be used in future performance assessment calculations to evaluate subsurface waste disposal at the SRS. Since performance assessment considers dose thousands of years in the future, it was also necessary to evaluate how 129I desorption changed as a function of time. Laboratory column and batch studies were conducted with waste materials collected from the F-Area and H-Area Groundwater Treatment Units, operated by the Environmental Restoration Division. Thirteen liters of effluent were passed through each column. This volume represents about 1000 years worth of water passing through concrete and 100 years worth of water passing through soil.
