Abstract: Once released into groundwater, contaminants interact chemically with both the native water and the rock matrix. Interphase reactions as sorption or precipitation are of primary interest because they considerably alter the contaminant mobility. Transport models frequently handle these interactions by using the Kd approach, assuming constant ratio of sorbed and soluble concentrations. In the near field of nuclear waste repository chemical interactions need to be modelled more rigorously. This paper summarizes the conceptual model, the numerical techniques and the software architecture, chosen for the development of a coupled hydrogeochemical model based on separated transport and chemistry existing modules.
