  Underground water is one of the important sources of exploitation in arid and semi-arid regions. Therefore, in order to preserve the quality of groundwater, it is important to be aware of the local transmittal and temporal distribution of them. The purpose of this study was to investigate the local variations of groundwater quality in Sabili lands using interpolation method. Sabilly area is located in the north of Khuzestan province, north of Dezful city, which is under planting about 9100 hectares. After landing, reference and digitization of the map and data of the Sabilly area including meteorological parameters, groundwater quality in the area as well as soil science, geology and land classification, layers were created in the ArcCatalog layer. To prepare a variety of quality maps of the area, firstly, the wells studied by x and y (latitude and longitude) were created as points with qualitative information in the GIS software. Then, with the help of interpolation techniques (IDW), the quality maps of the region have been extracted. The results of groundwater quality zoning showed that TDS deviations from 160 mg / lit in the north of the area in al-Mahdi township to 1646 mg / lit in the east of the region in Sarbisheh village has changed.The amount of sodium and potassium in the Sarbisheh area is high and around the Gurpsifid is medium and the rest of the plain is low. The sodium absorption ratio (SAR) in the Sarbisheh area is high and around the Gurpsifid is medium and the rest of the plain is low. The results also showed that, in terms of the bicarbonate hazard of the region, is in the proper category for irrigation, Also the studied area was desirable for irrigation because of this place has been rich in calcium and magnesium.
