Nearly a century of mining activities upstream have contaminated Lake Coeur d'Alene and its tributaries with Pb, Zn, and other heavy metals. Heavy metal concentrations in sediments of the Coeur d'Alene watershed have been shown to be inversely proportional to the sediment size fraction; thus, analysis on a very small scale is essential to determine the mobility and stability of heavy metals in this environment. Micron-scale synchrotron-based methods were used to determine the association of heavy metals with solid phases in sediments of the Coeur d'Alene River. Bulk X-ray diffraction (XRD), extended X-ray absorption fine structure spectroscopy, and synchrotron-based microfocused XRD combined with microfocused X-ray fluorescence mapping indicate the presence of crystalline Pb- and Zn-bearing mineral phases of dundasite [Pb2Al4(CO3)(4)(OH)(8)center dot 3H(2)O], coronadite [PbMn8O16], stolzite [PbWO4], mattheddleite [Pb-10(SiO4)(3.5)(SO4)(2)Cl-2], bindheimite [Pb2Sb2O7], and smithsonite [ZnCO3]. Likely phases for Zn and Pb adsorption were ferrihydrite, diaspore [AlO(OH)], manganite [(MnO)-O-(III)(OH)], muscovite [KAl2(Si3Al)O-10(OH,F)(2)], biotite [K(Fe,Mg)(3)AlSi3O10(F,OH)(2)], and montmorillonite [Na-0.3(Al,Mg)(2)Si4O10(OH)(2)center dot 8H(2)O]. The large predominance of Fe and Mn (hydr)oxides over other sorbent minerals suggests that the metal sorption behavior is dominated by these (hydr)oxide phases.

Hydrogeochemical investigation of groundwater characteristics in Alpu coal field, Eskisehir-Turkey Tural, Ceren Yazıgülü; Çamur, Mehmet Zeki; Department of Geological Engineering (2021-6) Hydrogeochemical characteristics and quality of groundwater resources in Alpu Coal field to the north of Porsuk Creek are investigated. EC, pH, DO and ORP average value ranges are determined as 438-1227 μS/cm, 7.43-8.69, 3.29-6.05 mg/l and 106-180 mv, respectively in spring waters and as 452-30233 μS/cm, 7.46-8.48, 0.6-6.0 mg/l ve 198- -183 mv, respectively in well waters. All spring waters are in HCO3 - Mg, Mix(Ca-Mg), Ca facies. Groundwater facies, stratigraphically downward: change in the order of HCO3, ...
Reductive dissolution and metal transport in Lake Coeur d'Alene sediments Şengör, Sema Sevinç; Ginn, T.R.; Moberly, J.; Peyton, B.; Sani, R.K. (2007-12-01) The benthic sediments in Lake Coeur d'Alene, northern Idaho, have been contaminated by metals (primarily Zn, Pb, and Cu) from decades of upstream mining activities. As part of ongoing research on the biogeochemical cycling of metals in this area, a diffusive reactive-transport model has been developed to simulate metal transport in the lake sediments. The model includes 1-D inorganic diffusive transport coupled to a biotic reaction network with multiple terminal electron acceptors under redox disequilibrium...
Polycyclic aromatic hydrocarbons (PAHs) in sea sediments of the Turkish Mediterranean coast, composition and sources Tuncel, Süleyman Gürdal (2015-03-01) The concentrations of polycyclic aromatic hydrocarbons (PAHs) were determined in 25 surface sediment samples from five sites located at Oludeniz Lagoon of the Turkish Mediterranean coast. The total concentration of the PAHs (1.85 +/- 1.39 mg/kg) was lower than the sediments from highly urbanized areas, while it was comparable with the sediments from similar locations. Acenaphthene and chrysene were dominant ones with the concentrations of 0.620 and 0.515 mg/kg, respectively. The isomeric ratios indicated th...
Heavy Metal Contamination Analysis of Bottom Sediments of Köycegiz Lake and Fethiye-Göcek Bay, SW Turkey Gülşen Rothmund, Halil; Avşar, Özgür; Avşar, Ulaş; Kurtuluş, Bedri; Tunca, Evren (null; 2018-04-13) In this study, the heavy metal contamination in the base sediments of Köyceğiz Lake and Fethiye-Göcek Bay in Muğla, Turkey was assessed. The focus lies mainly on Mo, Cu, Pb, Zn, Ni, Co, Mn, Fe, As, Cr and Al metals. The applied analysis methods on the data set of 150 sediment samples (81 samples in Köyceğiz Lake and 69 samples in Fethiye-Göcek Bay) are the following: contamination analyses (contamination factor, contamination degree, modified contamination degree, enrichment factor, geo-accumulation index, ...
Seismic Performance Evaluation of Concrete Gravity Dams by Using Pseudo Dynamic Testing and Simulations Aldemir, Alper; Binici, Barış (null; 2017-11-24) Dams are one of the mostimportantinfrastructure components servingfor water storage and energyproduction.Experimental studies on the seismic response of concrete gravity dams are scarce due to the complications regarding thelargescaleof dams and their interaction with the reservoir. This study presents the results of recent novel pseudo-dynamic dam tests (PSD) along with the nonlinear finite element simulations of the specimens. The test specimens were 1/75 scaled version of the highest ...
