    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groundwater contamination impacts on unconfined aquifer from which most of the drinking water in a part of Konya is withdrawn, For assessing the vulnerability, 7 hydrogeological maps are used.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.

    Stratigraphic Characteristics of the Derinkuyu Area, Nevsehir, Turkey
    (SPRINGER INT PUBLISHING AG, 2014) Sogut, Ali Riza; Kocak, Kerim; Guzel, Ahmet
    The study area is located in the Derinkuyu area, central Anatolia. The oldest formation in the area is Cretaceous Karatepe hornblende gabbro, which is overlain by upper Miocene Melendizdagi tuffs, Melendizdagi andesites, Gostuk tuff and ignimbrite, and the Karakaya Formation. These units are followed by lower Pliocene Selime tuff, Kizilkaya ignimbrite, and the Agilli Formation, above which lie various Pleistocene ashes, namely, the Hasandagi ash, the Kumtepe ash, and the Golludag ash flow tuffs. Above these are the Pleistocene Kizildag basalts and Holocene basaltic cinder cones. Talus is the youngest unit in the area. The young volcanics and volcaniclastics in the area may have originated from the volcanism of Mts Erciyes, Melendiz, and Hasan.
