When water from aquifers containing iron and manganese is exposed to air, these elements are oxidized (combine with oxygen) to less water soluble forms. Upon oxidation, colored forms of iron and manganese become visible in water. In the case of iron, white, then yellow and finally red-brown solid particles form that settle out of the water.

The elements were “pure” but could not be found in that state on earth. Every visible thing was made up of some combination of earth, water, air, and fire. The four elements were even used to described the four temperaments a person could have, and hippocrates used the four elements to describe the four “humors” found in the body.
If you do have water with a lot of iron bacteria that causes a rotten egg smell, we recommend choosing an aluminum/zinc/tin rod as it can help to control the growth of the iron bacteria. As mentioned above, you might have a water heater with a separate inlet for the anode rod or your anode rod might be installed on the hot water outlet.
