GROUNDWATER QUALİTY ASSESSMENT USİNG GEOGRAPHİC INFORMATİON SYSTEMS (GİS) IN BUCAK BURDUR, TURKEY

Abstract

The Bucak catchment area is located in Turkey’s Mediterranean region, south of Burdur Province; it has an area of 684 km2 . The area is one of the most important karst regions on the west side of the Taurus belt; it includes Bucak and Çeltikçi counties and numerous villages. In the current study, 20 groundwater samples were collected from different parts of the Bucak catchment area to assess water quality by analyzing several physical and chemical parameters. The coordinates of 20 boreholes were recorded by using Global Positioning System (GPS). All of the data was imported using Geographic Information Systems (GIS), and the inverse distance weighted (IDW) method was used to prepare thematic maps for groundwater quality in the Bucak catchment. Total dissolved solid (TDS) and electrical conductivity (EC) features and power of hydrogen (pH) were acquired by using a DO700 Portable Dissolved Oxygen Meter device in the field, and the chemical parameters were analyzed at the Acme (Canada) laboratory using the inductively coupled plasma mass spectrometry (ICP-MS) method. The results showed that the values of the parameters were within permissible limits according to the Turkish criteria (TSE-266, 2005)and World Health Organization (WHO, 2006),and that there were no significant contaminants in the groundwater.
