The study examined the Finite Difference Method for calculating pollutants and their behavior in groundwater. Pollution sources are point or regional in terms of place andtemporary or permanent in terms of time. Discretization, approximation, and finite difference-related methods were also discussed. In addition, the Finite Difference Method and the software MODFLOW and its quality index review package (RT۳D) were also examined for groundwater. This research can be a starting point for groundwatermodeling.
