INFLUENCE OF NATURAL AND ANTHROPOGENIC STRESSORS ON THE DYNAMICS OF GROUNDWATER QUALITY IN THE CONTEXT OF CLIMATE CHANGE

This study evaluates the seasonal variations in the quality of natural groundwater used for drinking purposes in the southern part of the Republic of Karakalpakstan - the Amudarya district - based on physicochemical parameters (TDS, TH, Cl⁻, SO₄²⁻, NO₃⁻). The analyses were carried out using complexometric titration with Trilon B and standard laboratory methods. The results indicate that during the summer season, the concentrations of TDS, TH, Cl⁻, and SO₄²⁻ significantly increased, leading to higher mineralization and a sharp decline in drinking water quality. In contrast, during the winter season, the water remained relatively softer, with lower salinity and mineralization levels. The findings demonstrate a strong correlation between groundwater quality in this ecosystem and climatic factors as well as anthropogenic influences.
