The paper discusses the physicochemical and hydrochemical characterisation of the waters of the rivers (Lukhuni and Tskhenistskali) in the areas adjacent to the arsenic processing enterprises of the Racha-Lechkhumi and Kvemo Svaneti region.
The paper summarises multi-year (2021-2024) data on the studied rivers. Based on the obtained results, the ecological condition of the rivers was assessed. Using the proposed equation and chemical indicators (Water Framework Directive-2000/60/EC), the river pollution index and river water quality were determined. According to the pollution index, both rivers were assigned water quality class 1 and belonged to the "clean" category.
