DETERMINATION OF WATER QUALITY CLASSIFICATION OF TSKHENISTSKALI AND LUKHUNI RIVERS ACCORDING TO HYDROCHEMICAL INDICATORS

Abstract
After decades of industrial exploitation ofarsenicoresmining enterprises in Georgia in the region of Racha-Lechkhumi and KvemoSvaneti, arsenic-containingwasteexists in the surroundingareas. Therefore, the hydrochemical studyof the research rivers of the region is ofspecialimportance. The paperdiscussesthe physico-chemical and hydrochemical characterizationof the waters of the rivers (Lukhuni and Tskhenisckali) in the areasadjacent to the arsenicprocessingenterprises. The papersummarizesmulti-year (2021-2024) dataof the studied rivers. Basedon the obtained results, the ecologicalconditionof the rivers was assessed.Using the proposedequation and chemical indicators the river pollution index and river water qualityweredetermined. According to thewaterpollution index (wpi), both rivers were assigned water quality class 1 and belonged to the "clean" category.
