In this study, groundwater quality and water features of Diyarbakir urban basalt aquifer which contains Baglar, Kayapmar, Sur and Yenisehir residential areas aimed to be determined. At this location, water wells opened for drinking water and irrigation water are used in the agricultural field. Therefore, in the study area, which opened in water samples taken from water wells were examined. It was reformed in the field, water samples were taken from the predrilled water wells. Water wells in the same coordinates are determined by Garmin etrex 30 handheld GPS system. Chemical analysis of water samples taken in the laboratory was made. The wells water's pH, Electrical Conductivity (EC) and Dissolved Solids (TDS) features were acquired by Portable Hanna HI 98125 pH/EC/TDS/℃ meter device at the field. At this study, basalt aquifer features are considered, and water quality and water chemical properties were determined in Diyarbakir city centre, pH, EC and TDS values of the water samples taken on site and those water chemical analyses were measured in the laboratory. Then, they were modelled by using ARC INFO 10.2.1 GIS programme and geostatistical analyst extension tool. At the end of this process, thematic map of Diyarbakir's basalt aquifer pH, EC and TDS were produced. 展开更多
