Why Do You Have Iron in Your Water?
Iron is one of the most plentiful resources on earth. It comprises at least five percent of the earth’s crust. It can be a very upsetting mineral in the domestic water supply.
So how does iron get mixed up with your tap water?
As rainwater and surface water penetrates the ground, it dissolves iron from surface runoff and underground geologic deposits. Because water is the universal solvent, it carries iron into aquifers, or underground water reservoirs, which serve as our groundwater sources or well water.
There are still lead and iron pipes in very old water distribution systems because plastic pipe widespread use took a prolonged development. This surplus of metal pipes in water distribution systems makes iron present in well water and city-supplied tap water.
What Types of Iron Can You Find in Water?
Groundwater or tap water can have two forms of iron – ferrous metals and ferric metals. Both “ferrous” and “ferric” mean “relating to iron” or “generally containing iron.”
Ferrous iron is the soluble form of iron found in water. It easily dissolves in water, and this characteristic makes it difficult to identify visually. Ferrous iron is sometimes called “clear-water iron” because it does not cause discoloration and turbidity to water.
Exposure of ferrous iron to air gives it access to oxygen. When this happens, the ferrous iron oxidizes and turns into ferric iron that makes the water cloudy.
We all know ferric iron as rust. Rust is an insoluble form of iron, and you can find it in well water and tap water. Oxygen-rich water sources have higher concentrations of ferric iron.
In many cases, ferrous iron in well water can be accompanied by iron-oxidizing bacteria. These organisms are chemotrophic bacteria, which means they multiply by using the energy they obtain from iron oxidation. Iron-oxidizing bacteria appear as bright red sludge in well water.
What Are the Undesirable Effects of Too Much Iron in Your Water?
Having too much iron in your water supply can cause different problems over time. Let’s go over these problems one by one, starting from the most noticeable to the most long-term effects.
Bad Odor and Taste
We drink water to sustain the daily hydration needs of our bodies. Drinking water with too much iron can smell metallic and leave a very undesirable taste on the palate. And since we also use water for cooking our food, we can find the same metallic taste and smell when we eat.
You will soon notice stains everywhere if you have too much iron in your water supply. Rust can cling to ceramic bathroom tiles and fixtures as ugly brown and red pigments that are very difficult to remove. Rust can also turn your white clothes and linens yellow after doing laundry.
As discussed in the differences between ferrous and ferric iron, too much rust can cause severe problems to our plumbing systems. If you filter out heavy metals before letting water enter your household, you can prevent major plumbing repairs in the long run.
Too much iron in bathing or shower water can damage healthy skin cells and reduce soap solubility. You can have soap residues on your skin and scalp, and you can end up having an early onset of wrinkles or other skin problems.
Drinking water with too much iron can result in iron overload. Excessive iron in the body can result in liver disease, heart failure, metabolic syndrome, diabetes, osteoarthritis, and many other conditions.
If you own a private source of groundwater, you might as well invest in the best iron water filter. It can remove rust and metallic taste and odors from your groundwater.
For easy-install applications, go for the APEC, Express Water, Home Master, or iSpring three-stage variants. You won’t be needing advanced plumbing experience for these devices. Plus, they don’t only remove iron. They also incorporate sediment and carbon-block filtration.
If you already have a reverse osmosis system in place and only want to remove the heavy metals from your well water, choose the single-tank air injection variants from DuraWater or AFWFilters.
Alternatively, if you have advanced plumbing knowledge, you can customize the Aquasana whole house system to have additional filters.
