    Assessment of Groundwater Vulnerability Contamination Potential of Konya, Turkey, Using Hydrogeological Specifications and GIS
    (ASIAN JOURNAL OF CHEMISTRY, 2009) Nalbantcilar, M. Tahir; Guzel, Ahmet; Durduran, S. Savas
    The aims of this study to assess the potential groundwater contamination impacts on unconfined aquifer from which most of the drinking water in a part of Konya is withdrawn, For assessing the vulnerability, 7 hydrogeological maps are used. These maps, depth to the groundwater, net recharge, aquifer media, soil media, topography, impact of the vadose zone and hydraulic conductivity are established and overlaid in GIS for the area. The overlaid (DRASTIC index) map indicates high vulnerability potential at central areas of the city. Groundwater samples are collected from different vulnerable areas. Chemicals (As, Cd, Ni and Pb) are analyze for testing of contamination degree. It is observed that the vulnerability category determines the contamination degree. The model is a useful and correct technique for assessing the aquifer safety.

    USEFUL VULNERABILITY MAPPING METHODS FOR GETTING GROUNDWATER: DRASTIC
    (INT SCIENTIFIC CONFERENCE SGEM, 2008) Nalbantcilar, M. Tahir
    Almost any places in the world, people are using groundwater for drinking and usage needs because of reduced Surface and spring waters sources in last decate. Settlement areas, agricultural areas, solid waste areas, industrial areas, waste water discharge areas have always potential to pollute the aquifer media. Boreholes areas for abstracting the ground water has to be picked up not to he carrying risk getting pollution Oil Surface. So it's necessary for the engineers that hydrogeologic properties has to be choosen before drilling because for best charge and time. The DRASTIC method, which is applied by EPA, has to be choosen for these applications. There are some steps preparing to this work on a map, which is called DRASTIC map is Occur front depth of groundwater, net recharge, aquifer media, soil media, topography, impact of the vadose zone and hydraulic conductivity of the aquifer maps. This map is showing vulnerability of Pollution for groundwater and the map includes different degrees of vulnerabilities. It has to be choosen the least Vulnerable area on this map when drilling for drinking water's. It's necessary to use these maps when resolution for building a factory whether to respond to people's using groundwater for drinking and usage or cities and probability getting Pollution activities. The using of DRASTIC method for getting fresh groundwater is coming by positive results around the world also in Turkey. As a result of polluted groundwater or to become injured, these sources to become clean again are too much costly and time consuming. On the other hand some of the polluted sources could not be clean again.
