Determination of Groundwater Threshold Values: A Methodological Approach Applied to the Gediz River Basin (Western Turkey) Dilek, Filiz Bengü; Yetiş, Ülkü; Duru, Burcu; Bulut, Onur Fatih; Cakmak, Özgür; Gunhan, Ozgur (2018-07-04) The purpose of the EU Groundwater Directive (2006/118/EC) is to prevent and control groundwater pollution. For this purpose, it requires member states to assess groundwater chemical status. To evaluate the chemical status of a groundwater body, threshold values (TVs) of the relevant risk-posing parameters should be established. In addition, TVs should be implemented in the river basin management plan to prevent or limit inputs of pollutants into groundwater. In the present study, TVs of the substances (12 m...
Determination of groundwater threshold values: A methodological approach Bulut, Onur F.; Duru, Burcu; Cakmak, Ozgur; Gunhan, Ozgur; Dilek, Filiz Bengü; Yetiş, Ülkü (Elsevier BV, 2020-04-20) This article is concerned with the establishment of natural background levels and threshold values for naturally-occurring parameters in groundwaters in the absence of relevant and accurate long-term spatial data. A new approach was developed and exemplified, adopting the groundwaters of the Gediz River Basin, Turkey, as a case study. The available groundwater monitoring data was from a one-year seasonal water quality monitoring campaign. The approach used combines pre-selection, selection and statistical e...
Determination of groundwater threshold values: a methodology applied to Gediz basin Bulut, Onur Fatih; Yetiş, Ülkü; Department of Environmental Engineering (2019) Turkish bylaw on Protection of Groundwater against Pollution and Deterioration requires the establishment of groundwater thresholds in groundwater bodies. According to this regulation, water status, as good or not, is to be determined based on the chemical status. Indeed, in a EU Project entitled “Background Criteria for the Identification of Groundwater Thresholds-BRIDGE”, in an attempt to the implementation of Water Frame Directive, a methodological framework has been developed to determine threshold valu...
Determination of Ambient Elemental and Organic Carbon Concentrations in Urban and Suburban Ankara Atmospheres: Estimation of Secondary Organic Aerosol Koçak, Ebru; Öztürk, Fatma; Aslan Kılavuz, Seda; İmamoğlu, İpek; Tuncel, Süleyman Gürdal (2017-11-04)
Determination of ambient elementel and organic carbon concentrations in urban and suburban atmospheres in ankara: estimation of secondary organic aerosol Koçak, Ebru; Öztürk, Fatma; Aslan Kılavuz, Seda; İmamoğlu, İpek; Tuncel, Süleyman Gürdal (null; 2017-11-04) The concentrations of organic carbon (OC), elementel carbon (EC) and secondary organic aerosol (SOA) in atmospheric particles were investigated at two sites in Ankara, Turkey. The results show that, mean values of EC, OC, SOA for urban station are 2.30, 10.44 and 13.59 μg/m3 respectively; the mean values of EC, OC, SOA for the suburban station were recorded as 0.85, 5.40 and 7.49 μg/m3 respectively. The summer and winter values of the EC concentration in the urban station were found to be 2.17, 2.48 μg/m3 ,...
