Poços de Caldas Report No. 11Testing of geochemical models in the Poços de Caldas analogue study
In order to test the geochemical models used in repository performance assessment, modelling groups were provided with selected major element analyses of Poços de Caldas groundwaters and asked to predict 'blind' the solubility, speciation and limiting solid for a number of trace elements. This report documents these predictions and compares them to field analyses. These tests illustrate particular strengths and weaknesses in current models/databases and allow recommendations for amendments/improvements to be made.
