我們可以給地下水下定义为地面下边的水,它的这种產狀使得它区别于地面上边的水和空气中的水。地下水可以突破地面而出,形成泉水或滲出水,甚至它可能在海洋中形成海中之泉——这种泉照例都是离海岸很近的。一般看來,要取得地下水必須打井或打鑽孔,但是并非所有的地壳中的水都能从岩石中吸取出來,而是在研究地下水时应考慮各方面的因素。 We can define underground water as the water under the ground, which makes it different from the water on the ground and the water in the air. Groundwater can break through the ground to form spring water or seepage water, and it may even form a sea fountain in the ocean - as is the case with springs that are close to the coast. In general, wells must be drilled or drilled in order to obtain groundwater. However, not all the water in the crust can be extracted from the rock. Instead, all aspects should be considered when studying groundwater.
