There is a need to shorten the test time for column tests and to build models that can grasp the behavior of contaminants. Against this background, a new advection dispersion analysis method that obtains parameters from the results of a “liquid-solid ratio batch test” in which the liquid-solid ratio is assigned stepwise within a predetermined range to the soil material that constitutes the source ground Was examined. As a result, it was suggested that the elution behavior of boron and sodium obtained by the column test can be reproduced by the advection dispersion analysis using the liquid-solid ratio batch test.
