Contaminant transport modelling used in MT3D is the same in the MODFLOW model when the MODFLOW model is successfully run and calibrated in hydraulic head, all data in MODFLOW are converted to MT3D package in order to deal with contaminant transport modeling in groundwater. The objectives of the study are to i). apply M3TD package as tools to establish the conceptual model of contaminant transport modeling, ii). simulate and predict the arsenic and copper substances contamination in groundwater. Conceptual model was developed by consists of i, j and k in the model Fig.3. Consequently, grid model encloses with 89 rows, 53 column and 4 layers, the length are 2650 m and 4450 m in x and y, respectively, Based on the result of the model, 0.067 mg/l of arsenic concentration is considered as point source of contaminant at borehole MB52 is transported with simulation time 10 years decreased to 0.000037 mg/l. The initial concentration copper is 142.95 mg/l at point source at borehole MB48, which is reduced to 2.192 mg/l after10 years simulation.
