Contaminant transport refers to the spreading of the contaminants from the source of contamination to the drinking water supplies. Nevertheless, the groundwater contaminant transport modelling is a rarity as part of the risk assessment process. Detailed calculations, in-depth scientific and technical knowledge is required in addition to understanding of complex hydrogeological settings. The development of commercial softwares has reduced the time and effort to predict the groundwater transport with varying hydrogeological conditions. Nevertheless, it remains imperative to understand the mathematical relations and definitions with respect to the constant and variable input parameters leading to 3D and 2D models. (A) This research is an attempt to gather the various numerical equations typically used for modeling the contaminant concentration and transportation within the groundwater system.(B) A workflow example for computer based modelling using GMS (Ground Water Modeling) software using the MODFLOW and MT3DMS simulation programs.
