Q What are the differences between hot springs and geothermal water? A Hot springs are natural outcrops of groundwater above 20°C on the ground surface, while geothermal water is a type of underground hot water formed by the warming of molten rock or natural warming with the depth of the ground surface. The cleanliness of the two is different. Hot springs are filtered through the layers of the lithosphere, filtering out harmful radioactive trace elements, and the water quality is clean and hygienic. Geothermal water is formed by the heat energy released by rare radioactive elements deep in the earth's crust during the metamorphosis process, and contains a large amount of harmful trace elements. Since the groundwater directly extracted by drilling has not been filtered through long-term natural precipitation and layer-by-layer penetration of the lithosphere, harmful substances still remain, so it is very harmful to the human body.
