Goals of geoenvironmental assessment of groundwater conditions in the Eocene-Quaternary aquifer in the Yamal-Nenets autonomous district in the context of the development of hydrocarbon deposits

Regional regularities in the spatial variations of permafrost conditions in the Yamal-Nenets Autonomous District, i.e., permafrost massif structure, cryogenic processes, and the hummock-depression relief they create, control the areal trend in runoff characteristics of Eocene-Quaternary aquifer system and migration of pollutants in the region. The assessment of geosystem tolerance to technogenic impact with global climate warming and permafrost degradation taken into account should be based on water balance calculations taking into consideration the depth and capacity parameters of water objects.
