    Hydrogeochemical Characteristics of Acidic Water Sources Around Can Region, Biga Peninsula, Nw Turkey
    (Muğla Sıtkı Koçman Üniversitesi, 2014) Şanlıyüksel Yücel, Deniz; Baba, Alper; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Acid rock drainage (ARD) is one of the major sources of water pollution in some countries. Densely generation of ARD have been seen around Can Region (Biga Peninsula-NW Turkey) due to altered (silicification, argillic alteration) volcanic rocks which contain sulfide minerals and specially pyrite and there is inadequate availability of neutralizing carbonate minerals. Forty water samples (including 17 drilling, 5 drinking water, and 18 spring water) were collected from 2011 to 2012. The result show that pH of water samples is lower than 5 in most part of study area.

    Assessment of Water Quality Related To Lead/Zinc Mines in Umurbey Dam Basin, Northwestern Turkey
    (International Water Association, 2017) Şanlıyüksel Yücel, Deniz; Baba, Alper; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    The purpose of this study is to determine hydrochemical properties of the water resources and to assess the potential environmental consequence of the mining activities in Koru and Tesbihdere lead/zinc mine districts, and investigate detrimental effects caused by mining activities on the water resources and sediment quality in Umurbey dam basin (Biga Peninsula, NW Turkey). Cadmium, Cu, Fe, Mn, Pb and Zn concentrations in sediments downstream of Tesbihdere and Koru mines and in Umurbey dam sediments are higher than average values of world river sediments.

    Determining Water and Sediment Quality Related To Lead-Zinc Mining Activity
    (Polish Academy of Sciences, 2018) Şanlıyüksel Yücel, Deniz; Baba, Alper; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    This study focuses on the Koru and Tesbihdere Pb-Zn mining districts, located at the upstream areas of the Umurbey dam basin. Mining activities in Koru, one of the longest operated mines in NW Turkey, date back to the beginning of the 1900s. The purpose of the study is to (1) determine the hydrochemical properties of the water resources and to assess the potential environmental consequences of mining activities in the Koru and Tesbihdere mining districts, and (2) investigate the effects caused by mining activities on the water resources and sediment quality in the Umurbey dam basin. Concentrations of As, Cd, Cu, Fe, Mn, Pb, and Zn in river sediments downstream of the Tesbihdere and Koru mining district, and in the Umurbey dam sediments were higher than the world average for river sediments. The geoaccumulation index and enrichment factor revealed that sediments were strongly polluted with Pb and Zn, moderately to strongly polluted with Cd and moderately polluted with Cu. The chemical analyses of water resources revealed that the maximum Fe, Zn, Pb, Mn, and Cu concentrations reached 2890 μg/l, 1785 μg/l, 1180 μg/l, 984 μg/l, and 419 μg/l, respectively. The Koru River is classified as polluted water according to Turkish inland water quality regulations. The environmental contamination problems in the local drainage system are caused by leakage from past and current tailing ponds into the Koru River.

    Geochemical Characterization of Acid Mine Lakes in Northwest Turkey and Their Effect on the Environment
    (Springer Verlag, 2013) Şanlıyüksel Yücel, Deniz; Baba, Alper; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Mining activity generates a large quantity of mine waste. The potential hazard of mine waste depends on the host mineral. The tendency of mine waste to produce acid mine drainage (AMD) containing potentially toxic metals depends on the amounts of sulfide, carbonate minerals, and trace-element concentrations found in ore deposits. The acid mine process is one of the most significant environmental challenges and a major source of water pollution worldwide. AMD and its effects were studied in northwest Turkey where there are several sedimentary and hydrothermal mineral deposits that have been economically extracted. The study area is located in Can county of Canakkale province. Canakkale contains marine, lagoon, and lake sediments precipitated with volcanoclastics that occurred as a result of volcanism, which was active during various periods from the Upper Eocene to Plio-Quaternary. Can county is rich in coal with a total lignite reserve >100 million tons and contains numerous mines that were operated by private companies and later abandoned without any remediation. As a result, human intervention in the natural structure and topography has resulted in large open pits and deterioration in these areas. Abandoned open pit mines typically fill with water from runoff and groundwater discharge, producing artificial lakes. Acid drainage waters from these mines have resulted in the degradation of surface-water quality around Can County. The average pH and electrical conductivity of acid mine lakes (AMLs) in this study were found to be 3.03 and 3831.33 μS cm-1, respectively. Total iron (Fe) and aluminum (Al) levels were also found to be high (329.77 and 360.67 mg L-1, respectively). The results show that the concentration of most elements, such as Fe and Al in particular, exceed national and international water-quality standards. © 2012 Springer Science+Business Media New York.
