At present, in the special hydrogeological literature much attention is paid to the problem of studying the impact of technogenesis on the quality of groundwater. In the development of these studies, the article gives a consistent analysis of the conditions of formation of hydrogeochemical zonality in the groundwater flow within the halo distribution of technogenic solutions of potash production.

One of the main reasons for changes in the chemical composition of groundwater during drainage of developed deposits is the intensification of the overflow of pressure, more mineralized water of deep horizons, or squeezing (due to the growth of intra-class stresses) pore water from weakly permeable layers and blocks with a general decrease in head in the upper aquifers.
