ABSTRACT Chemical and biological transformations can significantly affect contaminant transport in the subsurface. To better understand such transformation reactions, an equilibrium–nonequilibrium sorption transport model, HYDRUS‐1D, was modified by including inverse solutions for multiple breakthro...
