The ground water can be divided into "soft water" and "hard water". Soft water has tew impurities or none at all while hard water contains some more dissolved minerals. In general, hard water is drinkable, but it may have a slight taste because of various minerals.
One place where hard water can be found is a ground underlying a base of limestone arid shale. Rainwater dissolves materials as it comes down and this results in water’s taste and hardness.
We can sometimes find ground water that is almost as soft as rainwater under a bare sandy area. These days hard water from the underground is popular among the citizens of this country. They believe that mineral water is good for health, but some bard water has the dissolved minerals that are harmful to our body.
Scientists suggest that all the ground water should be specially treated before it is sold.

B、Hard water contains more dissolved minerals.
C、Hard water is not drinkable.
D、Soft water is easier to drink.
