We have studied the mechanism of natural formation of underground drinking and geothermal waters near the magmatic foci of extinct volcanoes located on the coast of the seas and oceans.
Studies carried out with the help of geocosmic means of groundwater search and resonance-test equipment made it possible to establish one of the mechanisms of natural formation of underground fresh and geothermal waters near the magmatic foci of extinct volcanoes located along the coast of the seas and oceans. The identified sources of underground drinking and geothermal waters are of important economic utmost for countries with arid climates. These sources of groundwater formation can be included in the overall balance of the water cycle on the planet and attributed to sustainable renewable freshwater resources that can be actively used for agricultural needs and as sources of drinking water supply for cities and towns.
