The complex nature of groundwater flow and the interaction of contaminant species with heterogeneous porous media have led researchers to develop sophisticated theoretical and numerical models for the general transport problem. This project was an attempt to address both needs. The objectives may be summarized as follows: (1) Formulate a procedure for estimation of adsorption parameters in situ, using an appropriate contaminant transport model. (2) Test the procedure in controlled laboratory experiments. The parameter estimation procedure was based on a model developed by Charbeneau (1981, 1982), with some important modifications, and is presented in the following section. The experiments were performed in a two-dimensional flow apparatus rather than in soil columns. Cation exchange processes were observed in six experiments. The experimental procedures and results are presented in a later section.
