Abstract

Anthropogenic environmental changes in Kazakhstan lead to changes in the formation of groundwater. The anthropogenic impact on the environment is expressed in the change of the relief and hydrographic network, the redistribution of water resources and the change in their qualitative and quantitative characteristics. An important consequence of anthropogenic influence is a change in the temperature regime of the territory and the nature of precipitation. The results of the analysis of the nature of changes in the formation of groundwater are given. The areas with the most strongly changed formation conditions, which include zones of ecological disaster in the Aral Sea region and the Semipalatinsk nuclear test site, as well as built-up areas of large industrial centers and urban agglomerations of cities, are identified. A comprehensive analysis of climatic, glaciological and hydrogeological materials on the territory of Kazakhstan was used as a research methodology to determine the influence of climatic and anthropogenic environmental changes on the formation conditions of groundwater. Comparison of the research results from different years with the materials of recent years identified that fundamental changes in the quantitative indicators of groundwater supply should not be expected and groundwater resources, unlike surface water resources, will not significantly decrease. The use of research results will allow justifying the expansion of water supply for the population at the expense of groundwater.
