Numericizing resource matching for specific pollutants defined in the surface water quality regulation

With the increase in the need for water resources whose quality and quantity have decreased due to industrialization, population growth, climate change and uncontrolled use, the issue of protection and development of water resources has gained importance. Sustainable use of water has been clarified at the European Union (EU) scale with the "Water Framework Directive (WFD)." Turkey is under water pressure according to the Falkenmark Indicator, and various legislations have emerged with the steps taken within the scope of the EU harmonization process. One of the most important of these legislations is the Surface Water Quality Regulation (SWQR). The importance of the integrated watershed management approach with the WFD has been revealed, and one of the benefits of this approach is the preparation of River Basin Management Plans (RBMP). Monitoring activities, which will show whether the environmental targets have been achieved or not, are one of the basic steps of RBMS's. Operational monitoring on a print basis is used to monitoring hazardous substances. Hazardous substances include the 45 priority substances and 250 specific pollutants and that are used to determine the chemical status of water bodies. Priority substances are pollutants defined in the WFD and specific pollutants are determined according to the basins in the countries subject to WFD and identified as a result of 3 projects carried out in Turkey are included in the SWQR. Priority substances and certain pollutants with chemical monitoring parameters should be followed up with monitoring activities so that they do not exceed the limit values and do not adversely affect the water quality. In this thesis, a pollutant card has been prepared for each of the hazardous substances and the physicochemical parameter; besides the various properties of the pollutants and parameters, their possible sources were also determined; the data obtained were summarized in a pollutant-source matrix and a case study was prepared by applying the prepared matrix to operational monitoring points in the Nilüfer Sub-Basin. With this study, it is suggested that basin-specific planning be made in the monitoring programs to be created in the new period, instead of the current wholesaler perspective, which includes the monitoring of each pollutant in each basin. Thus, monitoring activities are expected to be faster, more effective and solution-oriented.
