Abstract:
Considering the large number and variety of pollutants that may be released to the subsurface and the wide range of environmental situations (geological, hydrological, chemical. and biological) that may encounter, it is apparent that a highly systematic approach must be followed in developing a capability for predicting subsurface transport sufficient to meet the goals of groundwater pollution control. Accordingly , the major thrust of transport research should be directed towards the development of mathematical models that integrate physical process descriptions with pollutant properties and environmental characteristics to yield quantitative estimates of subsurface transport.
in the present note, a review of the existing methodologies of solute transport phenomena has been made, keeping in view the ultimate aim that is to provide methodologies which will permit accurate prediction of the effect from a point source pollutant activity will have on the quality of groundwater at points of withdrawal or discharge.
