Iron occurs naturally in soil, sediments, and groundwater and can be found in many types of rocks. Iron can be present in water in two forms; the soluble ferrous iron or the insoluble ferric iron. Water containing ferrous iron is clear and colourless, and when exposed to air the water turns cloudy causing a reddish-brown precipitate of ferric iron appears.

If you ever pour a glass of water from your home’s pipe, it seems to be rusty, or if the reddish-brown particles settle, there may be too much iron in your water. If you have iron in your water, you can certainly understand it by its taste. This offers a metallic taste to your water.
