ASSESSMENT OF THE STATE AND QUALITY OF HYDROGEOCHEMICAL INDICATORS OF ARTESIAN GROUNDWATER IN THE ZHAMBYL REGION

The results of a study assessing the condition and quality of groundwater in the Talas, Sarysu, and Moiynkum districts of Zhambyl region are presented. Fieldwork conducted in 2023 in these districts showed exceedances of chemical indicators of groundwater at wells No. 1, 8, 27, 61, and 66. The scientific work included field research and chemical-analytical studies of water samples from self-flowing wells to determine their suitability for domestic and drinking water supply, as well as for land irrigation. To improve efficiency, geoinformation support was provided. The analysis and generalization of the collected materials were carried out using a geographic information system (GIS) for developing predictive scenarios for the operation and protection of self-flowing wells. Based on the research results, both an analysis and an assessment were made of the potential for the fountain (artesian) exploitation of pressurized groundwater. Recommendations were given on the use of groundwater resources for the sustainable development of rural areas. Using GIS technologies, a geoinformation database of self-flowing wells and confined artesian aquifers of the territory was created for the first time, enabling more effective groundwater management and protection.
