Abstract: The U.S. Geological Survey three dimensional Heat and Solute Transport (HST3D) model is used to simulate fate and transport of dissolved contaminant in coastal aquifers. The model originally solves the flow equation, a single species solute transport equation, and the heat balance equation. In this study, the heat balance equation is converted by parameter transformation to a second species solute transport equation. A series of test cases are conducted to document the validity of this use of the model. The results are further confirmed by comparison with existing solutions for these problems.
