Underground water is called underground water, because it is "underground" not because it is fresh or salt. You can have underground salt water reservoirs just like you can have fresh water ones.
Less than 1 percent of Earth's water is ready for use by humans. Earth is approximately 71 percent water but of all this water only about 2.5 percent is fresh water with the rest being salt water and thus not fit for human consumption. Of the 2.5 percent fresh water the majority of this is frozen in the polar icecaps, present in soil moisture or deep underground where it is out of reach.
Underground water is cleaner.
The rest of the water is groundwater(underground water) or frozen water(icebergs, glaciers). It could also be freshwater(streams,rivers)
you know when there is water underground when you here the sound of water...(underground)...or see water on your lawn when there is no liquid to be found... : )

Less than 1% of the world's water is fresh water, with only a small fraction of that being readily accessible for human use. The majority of fresh water is trapped in glaciers, ice caps, and underground aquifers.
Underground water is called underground water, because it is "underground" not because it is fresh or salt. You can have underground salt water reservoirs just like you can have fresh water ones.
Around 95% of the Earth's fresh water supply is held in underground aquifers. These aquifers are large underground pockets of water stored in rocks and soils that can be accessed through wells and other extraction methods.
