This study focuses on the occurrence of two selected biocides, namely triclosan (TCS) and chlorhexidine (CHX), in the drinking water system of Ankara, Turkey. Samples were taken from the three main components of the drinking water system (camlidere and Kesikkopru Reservoirs, Ivedik Water Treatment Plant (IWTP) and the distribution network). Seasonal variations in biocide levels as well as their relation to general water quality parameters were sought. TCS levels detected in camlidere and Kesikkopru Reservoirs were in the range of 0.65-11.15 ng/L and 0.86-48.96 ng/L, respectively; whereas CHX levels detected were between <1.33-5.31 ng/L. TCS was completely removed in IWTP. In accordance with the result for the IWTP outlet, biocides in the distribution network were all below the limit of quantifications. Moreover, some conventional water quality parameters were related to the concentrations of biocides in surface waters.

Sustainable development and management of an aquifer system in western Turkey
SAKIYAN, J; Yazıcıgil, Hasan (2004-02-01)
This study presents the establishment of sustainable development and management policies for the Kucuk Menderes River Basin aquifer system in western Turkey. Geological, hydrogeological, and geophysical data are used conjunctively to define various hydrogeological units and their geometry. Distributions of hydraulic-parameter values and recharge are estimated by geostatistical methods and hydrologic simulations, respectively. A finite-difference groundwater flow model is used to represent the unconfined flo...
Real-time gas monitoring at the Tekke Hamam geothermal field (Western Anatolia, Turkey): an assessment in relation to local seismicity
Süer, Selin; Güleç, Nilgün Türkan; Parlaktuna, Mahmut (Springer Science and Business Media LLC, 2020-08-01)
This study presents the results of a real-time gas monitoring experiment conducted, via the use of a quadrupole mass spectrometer, in a mofette field within the Tekke Hamam geothermal site in western Anatolia (Turkey), a tectonically active region hosting several east-west trending grabens. The study is aimed to establish a baseline gas profile of the region. Within the framework of the experiment, gas compositions (CO2, N-2, O-2, H-2, H2S, CH4, He, and Ar) and flow rate of a mofette were monitored during t...
Cadmium removal using clinoptilolite : influence of conditioning and regeneration
Gedik, Kadir; İmamoğlu, İpek; Department of Environmental Engineering (2006)
Clinoptilolite samples obtained from two deposits in Turkey were tested for their potential in removing cadmium from aqueous solutions. Preliminary experiments in batch mode revealed inferior cadmium uptake at low pH. Particle size was found to have no effect on cadmium removal efficiency suggesting the use of exchangeable cations found in the internal/available sites. Increasing temperature yielded positive, whereas prewashing had no effect on cadmium removal using both clinoptilolite samples. The Langmuir...
Particulate and dissolved primary production along a pronounced hydrographic and trophic gradient (Turkish Straits System-NE Aegean Sea)
Lagaria, A.; Psarra, S.; Gogou, A.; Tuğrul, Selen; Christaki, U. (Elsevier BV, 2013-06-01)
The rates of particulate (PPp) and dissolved primary production (PPd) were estimated along a trajectory of variable environmental regimes formed in a narrow shelf area, following the course of Black Sea water masses (BSW) passing through the Turkish Straits System (TSS) into the NE Aegean Sea (BS-AS outflow). Seven stations in total were sampled, covering a transect from the eastern edge of the Marmara Sea basin to the NE Aegean Sea, during two consecutive cruises performed in October 2008 within the framew...
Variable-rate, variable-pressure production from a fractured gas well with large viscosity and compressibility variation: applicability of superposition time
Gül Ertunç, Kıymet Gizem; Kök, Mustafa Verşan; Özkan, Erdal; Department of Petroleum and Natural Gas Engineering (2017)
In this study, it was estimated that 71.8 standard tcm of methane can be available in the Black Sea gas hydrates. However, only 13.6 tcm of this amount was calculated as energy sources. With HydrateResSim simulator, gas production potentials from a hypothetical Class 1 hydrate in the Black Sea conditions by depressurization and depressurization with wellbore heating were simulated. Wellbore heating might be necessary to avoid hydrate reformation along the wellbore during production. For comparison with the ...
