Abstract
Hydrochemical characteristic of artesian and spring (drinking) waters available at the territory adjacent to arsenic processing enterprises of Racha-Lechkhumi and Kvemo Svaneti region in 2022-2024 has been considered in the work. There have been identified artesian and spring waters polluted with different ingredients.
The following conclusions have been made based on the carried-out studies:
in some cases, among ingredients polluting artesian and spring waters there has been registered increase of some components (mineral forms of nitrogen, water hardness, sulfates, mineralization, microbiological indicators) compared to respective MPCs; these waters belong to the category of medium-salt (average mineralization) waters, while an acid water of the spring located below Lentekhi is ranked among highly mineralized waters;
total arsenic content in the spring waters flowing towards Tsana in 2022-2024 has surpassed the MPC and arsenic hazard quotient HQDw >1, so these waters are at risk;
arsenic concentration in other spring waters is within the norm.
