“…Osnovni ciljevi ovog zakona su: obnavljanje i održavanje hemijskog, fizičkog i biološkog integriteta svih voda, obezbeđivanje kvaliteta vode u cilju zaštite i održanja biodiverziteta i moguće korišćenje vode za rekreaciju i kontrola ispuštanja zagađujućih materija. Vodeći princip kod obnavljanja oštećenih akvatičnih ekosistema u SAD je princip maksimalnog dnevnog opterećenja (Total Maximum Daily Loads, TMDL), koji je primenljiv kako za tačkaste tako i za difuzne zagađivače [19]. TMDL predstavlja najveću količinu opterećenja koje vodno telo može da primi, a da ne dođe do prekoračivanja vrednosti propisanih standardom kvaliteta voda i čini ga suma individualnih opterećenja iz koncentrisanih izvora i opterećenja iz rasutih izvora uključujući opterećenje koje potiče iz prirode, sa uračunatom granicom sigurnosti (nesigurnost u vezi sa odnosom između opterećenja zagađivačima i kvaliteta vode vodoprijemnika ili merna nesigurnost) [20,21].…”

One of the key stages of the process of preparing management plans for the river basin is the analysis of pressures and impacts, as well as the risk assessment of failing to achieve the environmental objectives. DPSIR framework (Driving Forces-Pressure-State-Impact-Response) was developed by the European Agency for the environmental protection, and makes the conceptual basis for the pressures and impacts analysis, taking into account the complexity of the interactions in the environment and represents the tool for their analysis. Impact assessment of the water body requires some quantitative information to describe the condition of the water body and/or the pressures that act on it. The aim of the study was to determine the effect of wastewater discharge on Krivaja watercourse. Impact assessment is carried out based on data of polluters? wastewater and monitoring information for water in Krivaja. For each site at which sampling was performed, the specific risk quotients for surface water were calculated, as the ratio of the each pollutant concentration in surface water at the sampling point and environmental quality standards for pollutants, as well as their sum that represents the risk index. In order to have the integrated perceive of processes in the Krivaja River, taking into account cumulative effects from point sources, the concept of total maximum daily load was applied, using which the pollution amount, that can be discharged daily in a water body without degrading his prescribed/required quality, was calculated. Comparison of emitted loads from pollution point sources with maximum allowable ones was performed. Wastewaters of different polluters located on Krivaja are, due to insufficient treatment, very loaded with organic matter and nutrients. Krivaja receives daily 1332 m3 of wastewater, 999 kg COD, 722 kg BOD, 144 kg of nitrogen, 4.3 kg of phosphorus and 627 kg of suspended solids. Of the total wastewater volume, the majority (69%) originates from municipal wastewater, 81% of the total amount of organic matter comes from the industry, while nutrients mostly originate from municipal wastewater. Loading of Krivaja with wastewater is major, uneven and unbalanced. Water quality of Krivaja is unsatisfactory. According to national legislation there is the exceedance of maximum permissible values for Class II for watercourse (good status) for most parameters, in all sampling locations and in both sampling periods. Parameters that exceeded the value for the Class II are dissolved oxygen, organic matter content, suspended solids, nutrients. Water flow in the river is not sufficient to receive the total amount of the pollutant load from point sources. Risk assessment, based on the monitoring results, indicates that the river Krivaja is possibly at risk of failing to meet the required water quality because the most of the values exceeded the limit values.

“…Non-point source pollutants are difficult to determine, being even more difficult than point source pollutants [1]. Especially in areas near rivers and lakes, non-point source pollutants were influent water systems without any management to decrease pollutants, which is one of the reasons why water quality of the water system has decreased [2][3][4]. Previous researches were reported that non-point source pollutant loads are higher than sewage treatment plant effluent [5,6].…”

A B S T R A C TDetermining impairment of water bodies in the light of watershed characteristics is useful in selecting applicable water quality indicators as target pollutants for the watershed management. This study investigated impaired water bodies using frequency analysis on a stream zone basis in Geum river basin in Korea. The river basin was divided into three stream zones by its characteristics. Selected water quality parameters discussed in this study were pH, DO, BOD, COD, SS, T-P, T-Coli, and F-Coli. Excess ratios of the water quality parameters were used to discriminate water bodies that did not meet water quality standards. Excess levels were used to classify the water quality degradation. Contributions of the tributaries were also estimated to identify the major contributors to the stream zones. The upstream zone showed that the indicators for impaired water bodies were BOD, COD, T-P, and T-Coli which indicated especially high excess level. The downstream zone revealed that COD, T-P, and T-Coli were the indicators and the M/D stream zone revealed that the indicators were BOD, COD, and T-P. The major contributors in the upstream are Okcheon, Juwon, Bonghwang, and Pumgok tributaries. In the downstream, Nonsan, Seokseong, Gab, Yudeung, and Daejeon were the major contributing tributaries and in the M/D stream zone, the major contributors were Iksan, Gobu, and Jeongeup tributaries.
