DETERMINATION THE WATER QUALITY CLASSIFICATION OF THE RIVER KHRAMI AND ITS TRIBUTARIES
Keywords:
Rivers, pollution, heavy metals, biogenic compoundsAbstract
The rivers Poladauri, Kazretula, Mashavera and Khrami were selected as the study subjects, since they are the main water arteries of Eastern Georgia, particularly Kvemo Kartli, and are under a certain anthropogenic impact. The paper summarizes the results of several years (2015-2020) environmental assessments of these rivers. Hydrochemical parameters (forms of biogenic elements, heavy metals, basic ions) and physicalchemical parameters (pH, electrical conductivity, salinity, °t, dissolved oxygen-DO) were determined in the analytical samples. Based on the obtained results, the ecological condition of the rivers was assessed. Using the proposed equation and integral chemical parameters (taking into account the Water Framework Directive -2000/60/EC), the pollution rate of the rivers and the water quality classification of each river were determined. All types of hydrochemical and physical-chemical analysis were performed using modern methods that meet and comply with European standards. It should be noted that of the rivers studied, the Khrami River is a transboundary river, which significantly increases the urgency of the work.
