Although water can contain contaminants, which are usually removed by water-supply systems, the plus side is that the water you drink likely contains a number of dissolved minerals that are beneficial for human health. Color in drinking water can be caused by dissolved and suspended materials, and a brown shade in water often comes from rust in the water pipes. Dissolved chemicals in drinking water can be less than desirable. If you have ever drunk water containing a bit of iron in it, you would know from the metallic taste left in your mouth. "Care for a cup of delicious water?It's just a bit of suspended ferrous iron!"Ĭredit: Petr Kraatochvil, Public Domain Pictures Color and drinking water Sources/Usage: Some content may have restrictions.
