Abstract: The results of the evaluation of different interpolation methods for each of the parameters studied in 2006 showed that for calcium, bicarbonate, sodium, adsorption ratios of sodium and sulfate (the Kriging method) and for the electrical conductivity parameters, the total soluble concentration and magnesium (IDW2 method) and for chlorine (IDW1 method) have the lowest MAE and MBE and in 2013, for the parameters of bicarbonate, calcium, total soluble concentration and magnesium (IDW2 method) and for sodium parameters, the adsorption ratio of sodium and sulfate (Kriging method) and for electrical conductivity and chlorine parameters (LPI method) were the best methods. Finally, the classification of the district water showed that in 2006 the only Barmshoor, Doodeman and Shagholein stations had limitations of drinking as term of TH parameter and in 2013 Barmshoor and Doodeman stations were in the most unfavourable waters as term of TH and TDS parameters.
