Groundwater地下水 is water that sits under the ground是存在地底下的水 in the soil and in the small cracks of rock藏在土壤裡和岩石的小縫隙中 Rain falls雨水落下 sinks in滲進地裡 and some of it stays down there有一部分就留在下面 filling the spaces填滿那些空隙 like a hidden sponge就像一塊藏起來的海綿

Though actually不過其實 it does move它還是會移動 only very slowly只是非常緩慢 from one place to another under our feet在我們腳下從一處慢慢移到另一處 If people take too much如果人們抽取太多 or if dirty water soaks down from farms and towns或是農田和城鎮的髒水滲下去 the groundwater in a whole area整個地區的地下水 can run low or become unsafe可能會枯竭或變得不安全 and you would not know from looking at the surface而你光看地面根本看不出來
