Abstract A solute model developed by van Genuchten and Wierenga was used to calculate 2,4,5‐T effluent data from soil columns. The model had been previously shown to adequately predict effluent data given model parameters curve fit to a portion of the effluent curve. The present work shows that 2,4,5‐T effluent curves may be adequately predicted without prior knowledge of the effluent curves for a particular soil column given: (i) model parameters derived from 2,4,5‐T effluent curves for other soil columns, or (ii) model parameters obtained from tritium effluent curves for the same columns. The data suggest that once the physical model parameters have been characterized for a soil, reasonable predictions of 2,4,5‐T (and perhaps other solutes) transport can be made given the adsorption coefficient for the solute.
