ARTICLE ANNOTATION

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.
