It is paradoxical, but it was noted by B.L.Lichkov in 1932 that in the works of V.I.Vernadsky one cannot find the words hydrogeology, hydrogeologist, hydrogeological research, although his works are an inexhaustible storehouse of hydrogeological ideas that defined new directions in hydrogeology, laid the foundations of the theory and methods of research of the underground hydrosphere.

In the work we have already substantiated the position on the difference between the hydrogeology of land, oceans and the belt of transition between land and ocean. Among these three hydrogeological "whales" continental margins (land-ocean belt) were out of the field of hydrogeology, although geologists have been studying the geology of these areas for many years and not unsuccessfully.

Sulfate reduction is one of the global processes that are active both in near-surface conditions and in the deep subsurface.

The Severodvinsk depression is located in the lower reaches of the Northern Dvina River and is a large erosional depression dipping towards the White Sea and extending to the shelf.

This present article, summarizing the results of research conducted in recent years by the Department of Hydrogeology of the Leningrad Mining Institute, and prospecting and exploration for therapeutic mineral waters, conducted by PGO Arkhangelskgeologiya, is the first experience of hydrogeochemical typing of therapeutic mineral waters of the Severodvinsk artesian basin.

To date, the average total capacity of the drainage system of the sinkholes of PO Phosphorite is about 3 thousand m³/ h, approaching in the flood period to 8 thousand m³/ h.

The purpose of hydrogeochemical studies conducted by the authors in the areas of distribution of ten gold ore fields with different landscape-hydrogeochemical conditions, was to develop a methodology for prospecting for primary mineralization.

The Amgun-Sikhote-Alin mountainous folded region, located in the lower reaches of the Amur River, is a geologically complex area, within which intrusive, effusive, volcanogenic-sedimentary and sedimentary formations are developed.

High-potential geothermal deposits, as a rule, should be assigned to the third category of complexity of geological and hydrogeological conditions of formation, circulation and discharge of groundwater.

The Izhorskoe groundwater deposit (IGWD), a typical fracture-karst water deposit of humid regions, is a water-bearing system located within the Izhorskaya Upland and includes fresh groundwater in Ordovician carbonate strata and Cambro-Ordovician sands and sandstones.

According to the conditions of occurrence, distribution and condition, it is the thickness of melomergel sediments in the deposits of the Kursk Magnetic Anomaly (KMA) that controls the quality of groundwater in the region.

Well testing is carried out to study the initial hydrodynamic, thermodynamic and hydrochemical parameters, to predict possible changes in their operating conditions and to obtain initial information for calculating the operational reserves of thermal waters.

Problem statement. At the present time in the quarry "Mir", due to its high watering with brines (over 1000 m3 / h), especially acute issue of mining, technical and environmental safety in further excavation of minerals.

The accuracy of interpretation of indicator sampling within the framework of typical calculation models is significantly affected by the combination of filtration heterogeneity of the reservoir and natural filtration flow, leading to a peculiar physical effect.

Creation of impervious blankets (PF3) around the "Mir" pipe does not solve the problem of utilization of highly toxic drainage brines: even under the protection of ASC in the quarry will be filtered brines with a flow rate of 300 m³/h and more.

The article considers landscape-hydrogeochemical conditions of the experimental site, located in the basin of the Natynka River, a left tributary of the Moscow River, in the zone of technogenic impact of the mining and chemical plant.
