Groundwater systems globally provide 25 to 40 percent of the world’s drinking water. The groundwater pollution which is of some concern in the area is mainly by industrial waste-Disposals and agricultural activities. Konya is one of the most significant industrial cities in Turkey. Groundwater is essential for drinking water source in the Konya city centre. The purpose of this study is Suitability of groundwater for drinking water in Konya centre by calculating the WQI and using Geographical Information System (GIS) techniques. To evaluate spatial and temporal of the groundwater quality by using geostatistical analysis based on data from 80 groundwater wells, groundwater samples were analysed for electrical conductivity (EC), hardness ( ?F), Ca2+, Mg2+, Total Hardness (TH) as CaCO3, Cl? and SO42- and Water Quality was compared for the World Health Organization WHO drinking water standards. ArcGIS package programme was used for the application of a kriging method, semivariogram model selection, and development of a distribution pattern of groundwater quality parameters and best model has been chosen for each parameter. It was specified in many places that (EC), hardness, Ca2+, Mg2+, TH and SO42- in most samples specially in Selcuklu region exceeded the allowable levels according to WHO and EC standards, and the resulting undesirable effect on human system, which indicated that the groundwater might be polluted and unsafe for drinking. For this reason, in this investigation water quality and level in WQI were analysed using computer modelling programme.
