Since childhood, we have read and heard that about 70 percent of the earth is covered with water. But most of these are salty, which is not fit for drinking. We all drink water by extracting it from underground. But do you know how much water is drinkable under the earth and how much water is still left. Actually, scientists have explained in detail about the water remaining under the earth in their research. Know what the scientists told.
Scientists’ report
According to the report of Live Science, scientists of the University of Saskatchewan had conducted a research in 2021. In this research, he wanted to know how much water is hidden in the soil or rocks beneath the earth’s layer. It was revealed that the oceans remain the largest reservoir of water on the planet, containing approximately 312 million cubic miles of water. But there is no less water inside the earth also. The Earth’s core contains about 43.9 million cubic kilometers of water, which is about a quarter of the total water present on Earth. At the same time, much less water (about 6.5 million cubic miles) is hidden in the ice of Antarctica. But the special thing is that most of the water present under the earth is potable.
How much water is present under the earth?
Journal Geophysical The report published in Research Letters states that the water we draw from the ground has been present inside the earth for centuries. We extract a lot of water from it every year, but it gets recharged again through rain and other sources. A report was published in Nature Geoscience Journal in 2015. It was estimated that the upper 2 kilometers of the Earth’s crust is filled with 22.6 million cubic kilometers of water. But now according to the report brought by scientists after research, it has become 23.6 million cubic kilometers.
Potable water under the earth
< p>Research author Grant Ferguson told Live Science that this is mostly fresh water. It can be used for drinking and irrigation. On the contrary, the deep groundwater is salty. In some places it is quite salty. But he said that it is not as bad as the water of the oceans.
