Conceptual Model of Relevant Processes

Since a comprehensive discussion of the conceptual model of processes is beyond the scope of this paper, the reader is referred to Finkel et al. (1998) and Finkel (1999) for more details. The behaviour of surfactants and their possible influences on organic substances is well described e.g. in West and Harwell (1992), Danzer and Grathwohl (1998), and Danzer (1999). 

The model described above was verified and validated with regard to column experiments at the laboratory scale (Finkel, 1999 Finkel et al., 1998). The results provide evidence that the conceptual model of processes (Fig. 7.7) is appropriate to represent all relevant processes and interactions occurring when PAH and surfactants migrate in the groimdwater (Finkel et al., 1998).
