An analysis of existing modern ecological problems of the territory of the village was carried Solotvyno, namely: intensive development of deep karst; changes in the hydrogeological regime; violation of the integrity of the salt massif and its destruction with corresponding deformations of suprasalt deposits and surface relief. Analyzed the dynamics of depression formation on the earth's surface within the township. Solotvyno, the dynamics of the expansion of the reservoir area. The methodological aspect of the assessment toolkit of the integrated ecological and technological situation within the Solotvyno territory has been developed. The indicator of transformation in time and space, the index of detection of relative changes in the environment in relation to the development of suffusion-karst processes, which must be taken into account when solving issues of ecological danger, and the normalization of indicators of surface water pollution in the form of a pollution index (I zabr) was made due to the assessment of the chemical components of surface waters of the studied area based on the method of normalization of actual concentrations of monitoring data in the calculation to the MPC. Spatio-temporal maps of the levels of indices of detection of relative changes in the environment (transformation) have been created in the form of cartograms with reference to the area. The index of detection of relative changes in the environment is proposed to be defined as the ratio of the area of transformation for several periods of time, using space monitoring technologies (Landsat 7 satellite images) and performing calculations with the help of Google Earth software, GIS modeling and statistical calculations. It has been established that due to the construction of isolated basins, which local residents fill with oil pumped from the pits above the mines, the complex of significant long-term irreversible changes in the environment increases, which leads to the destruction of the balance in the natural and man-made system and to significant negative consequences. Water withdrawal in modern times provokes the activation of suffusion-karst processes due to the increase in the radius of the depression funnel of the "big well" and contributes to the increase in the area of water catchments. A decrease in the level of the stationary water surface in the lakes above the mines under the condition of pumping creates the conditions for an additional inflow of water from the aeration zone and groundwater into the sinkholes due to the establishment of the level. The formation on the earth's surface of such forms of relief as gouges, sinkholes and displacement funnels flooded with water do not look stable during the period of research (2014-2020). According to the results of modeling the transformation index, it was established that the areas of the listed landforms have increased almost 15 times. It was established that the highest indicator of the first in some areas belongs to chlorine (Cl). That is, the dissolution of salts is prolonged.
