Whenever the concentration of dissolved mineral salts gets too high, the water becomes hard water.
Hard water has very high dissolved mineral content as compared to soft water.
It is mainly due to increase in the concentration of Ca2+ and Mg2+ ions in water.

Is soft water for drinking or hard water?
Both types of water are used for drinking. Water from wells is usually "hard" water; water from lakes or rivers is usually "soft" water (but this may not be true in all cases; rivers or lakes that are fed primarily by springs will usually be hard-ish water compared to rivers or lakes that are formed primarily from rainfall or snow melt runoff). There's nothing inherently wrong with drinking hard water; in fact it may be slightly healthier than soft water, because it contains calcium (and often iron). However, if you're used to soft water, hard water will taste funny to you and vice versa.
