Iron in water does not usually present a health risk. Your body needs iron to transport oxygen in the blood. Most iron comes from food since the body cannot easily absorb iron from water. Iron may present some concern if harmful bacteria have entered a well. Ferrous oxide, commonly known as iron(II) oxide, contains iron that lost 2 electrons in the oxidation process. So it can bond with other atoms with an extra 2 electrons. Ferric oxide is commonly known as iron(III) oxide. It contains iron that lost 3 electrons. Iron and iron oxides are natural components of the earth's crust. Iron oxides are extracted from iron ore and can be converted to iron. Iron and iron oxides are used in numerous applications in nanoscale and larger forms. Therefore, there are different ways of releasing into the environment—Rust from Iron (III) oxides with limited oxygen and low moisture results in black rust.
Black rust can be visually identified as a thin, black film from oxidation in a low-oxygen environment. Black rust has an appearance of almost a black stain. Zinc, the more reactive metal, will react with oxygen faster than iron, copper, and gold. Therefore, zinc will undergo corrosion at a faster rate. Does Aluminium Corrode? While aluminum doesn't rust, it does corrode. The aluminum oxide coating is highly resistant and renews itself if damaged, keeping the metal relatively safe from corrosion. This layer is harder and thicker than red rust and can also be called magnetite. This rust will stay tightly bound to the base material and act as partial protection from a further oxidization process.
