Abstract :

Entry of heavy metals in water resources will reduce water quality for drinking or agricultural irrigation. Various mathematical models such as spatial distribution model in the classification and prediction of arsenic concentrations in groundwater were used. Hence, it is tried in this study to assess the prediction accuracy of this model. Arsenic concentrations was measured by atomic absorption spectrophotometer model DR2800 in 2916 water samples collected from 27 wells (17 main wells, 10 control wells) performed in Hasht Bandi area of Minab. Then, predicted As concentration was statistically analyzed by the model of the spatial distribution with concentrations measured in 10 control wells. Mean and range of As concentrations in 27 main and control wells were 9.22±4.6 µg/l and 0–23.7 µg/l, respectively. The average concentration of As in the autumn, winter, spring and summer was 5.99±6.08, 13.14±6.43, 4.5± 13.06 , 4.69±4.6 µg/l. the ratio of As predicted mean concentration (7.69 µg/l) by the measured model (10.7 µg/l) equals 71.8 %. Spatial distribution model has a high accuracy to predict As concentration of groundwater.
