Assessing the vulnerability of aquifers is the first step toward careful management of groundwater resources.The gro-
undwater quality has to be evaluated to avoid or, at least, to minimize impacts on agriculture. The main objective of this study was to sit up a simple method to assess the groundwater quality and to map their spatial variation in terms of suitability for irrigation in Darb El-Arbaein area and the complementary objective was to demonstrate the GIS capabilities in exploring the full value of environmental data through spatial analysis and visual display of geographic information.Thirty six surveyed wells represented four villages with GPS data were used to assess and map the groundwater quality
