Abstract

GROUNDWATER is the most important water resource in arid and semiarid area. Therefore, GROUNDWATER pollution is also important. In this study, SPATIAL DISTRIBUTION of GROUNDWATER quality was evaluated in Shoor River basin in Dehaghan County, south of Esfahan Province. For this propose, kriging, cokriging and IDW methods were used to predict SPATIAL DISTRIBUTION of GROUNDWATER quality parameters related to 48 wells and Qanats. According to Anderson Darling test, data of WATER QUALITY were not normally distributed and therefore COX-BOX transformation was used to normalize the data. Next, the variogram of each parameter was drawn for fitting the best INTERPOLATION model. Then, SPATIAL DISTRIBUTION maps of GROUNDWATER quality were drawn using ArcGIS. Results showed that ordinary kriging was the best INTERPOLATION method for most of the parameters. According to the SPATIAL DISTRIBUTION maps, pollution was aggregated in north of the basin which agreed with the hydrogeological condition in the basin. Also SPATIAL DISTRIBUTION of WATER QUALITY INDEX (WQI) was determined in the area according to Water Health Organization Standard.
