Note. Ordovician limestone aquifer groundwater (simplified as type I), carboniferous limestone aquifer groundwater (simplified as type II), coal sandstone aquifer groundwater (simplified as type III), and Quaternary system aquifer groundwater (simplified as type IV). The water samples (numbers 1–38) are used to rebuild the model. The data (numbers A1–A13) in Table 1 are not used to build the model, which is only used to validate the model.
