The problem of transport of pollutants in groundwater flow from a polluted shallow pond to a natural stream is considered. A numerical model predicting changes in quality of ground water and of seepage effluent into the stream is developed. The Alternating - Direction implicit (ADI) finite - difference technique is employed in the solution. Using a small computer, a program is developed in order to carry out the necessary calculations. The program is documented so as to facilitate practical applications. Results are presented showing the effects of the variation of different parameters on the tracer displacement fronts and on effluent water quality.
