A Brief Background of Iron in Well Water

Before we jump into the list of the best iron filters for well water, we wanted to go over some important topics. We believe understanding the problem will be more helpful while finding the best solution for well water with iron.

What Is Iron in Well-Water?

In simple terms, iron is a mineral found in nature. It’s one of the most common and widespread minerals available.

Iron naturally appears in lakes, rocks, soil, sediments, rivers and underground water. Moreover, it seeps into water source from ores, wastes and iron-relating reactions.

Types of Iron Found in Well-Water

Iron may appear in well water in the three different forms.

1. Ferric iron

It’s an insoluble form of iron, known as rust. In general, ferric iron appears in the oxygen-rich water source.

If your well water is bright orange or red rust colored, it’s an indication you’re dealing well water with ferric iron.

Ferric iron is sticky and causes clogs in the water system.

2. Ferrous iron

Ferrous iron is found in well where the water is less exposure to sunlight and doesn’t carry oxygen. It’s a soluble form of iron.

The presence of ferrous iron makes no turbidity or discoloration to the groundwater. So, it’s also known as clear-water iron. But when exposed to air, it oxidizes and transforms to ferric iron and makes the water cloudy.

It has staining properties and also affects the smell and taste of water.

3. Bacterial iron

It’s the nastiest configuration iron. When bacteria in the well water makes bonding with the iron, this form of iron occurs. It’s a bright red colored sludge.

Bacteria iron causes severe stains, odors and blockages that ultimately ruins water booster pumps, water filters, and softeners.

This configuration may create the harmful conditions where noxious pathogenic bacteria can grow.

Iron in Well Water Sources – How Does It Get in?

Primarily, this mineral gets into well water by seeping in from the earth hardened layer.

Rainwater pervades the soil and the underlying geologic formations helps to dissolve iron. And it deposits into the underground aquifers, sources of groundwater for wells.

No matter how diligently you maintain your well, the presence of iron in well water is unpreventable.

This mineral can also get into your well water from exposer to corroded and rusty plumbing.

Old and corroded iron pipes running from your well water sources leave brown or red-colored flecks in water and stains on the drains.

Effects of Too Much Iron in Water

Too much iron in drinking or household water has various Health Effects and Other Issues. Let’s explore them.

Is it safe to drink well water with iron?

An acceptable iron levels in well water is beneficial to human health. In fact, iron in water is essential to a healthy, balanced diet that transports oxygen throughout the body and contributes to red blood cell production.

But if it goes beyond the safe levels, iron may create adverse effects.

  • Iron in your water can change its flavor, the taste of beverage, tea and coffee.
  • It also leaves an unpleasant, sharp odor in drinking water.
  • Drinking well water with high concentrations of iron can cause toxicity such as Hemochromatosis.
  • Iron’s staining also effects on the human body. High concentrations of iron in shower water turns your hair orange and leave your hair lifeless and brittle.
  • Iron in water effects on skin. Bathing in high-concentrated iron water negatively affects your skin. It adds a reddish tint on your skin.
  • High –concentration of iron in shower water may dry out pores, and also worsen skin conditions like acne and eczema.

How does iron in water negatively effect your household?

  • Iron forms a horrible bright-colored stain on linked surfaces, which may harm your household appliances.
  • Coarse orange or yellow marks may appear in your toilet bowl.
  • Bright yellow and red trails may appear surrounding the drains and around the rim of the kitchen or bathroom sink.
  • Showers and bathtubs become discolor due to iron concentrations in water.
  • Your laundry and dishes may get red and brown staining after being washed in iron water.
  • Iron residue accumulates inside your plumbing and clogs pipes and reduce household overall water pressure.
  • Any appliance and fixtures that use iron water will fall victim to iron build-up, which may lead to frequent and costly replacements.

How to Remove Iron from Well Water Source

How to Remove Ferrous Iron from Well Water

There are various methods to get the job done.

1. Using an Iron Filter

This system is useful if your water has 7 to 15 mg/l ferrous iron. By oxidizing the ferrous iron into the insoluble ferric iron, this process produces precipitation. Finally, the ferric iron precipitation is sorted out.

Iron filters use two common ways to do this job.

a.  Using an oxidizing filter media

b.  Pumping chlorine, ozone, or air into the water

This system is not recommended to use if there is organic matter in water. Again, it can’t treat bacterial iron in well water.

2. Using an Oxidizing Agent + Filter

This method is applicable to a higher amount of ferrous above 10mg/l.  The chemical oxidation plus water filter treatment is the cheapest way to remove iron from well water.

This method uses an oxidizing agent such as hydrogen peroxide or chlorine. The agent oxidizes the iron present in water. Finally, the filter eliminates the oxidizing agent before you use the water.

Downside of this system is it requires regular backwashing and chemical refilling.

3. Using an air injection with filter media

To remove ferrous iron, you can use an air injector in combining with the filter to remove the iron up to 30 mg/l.

An air injector injects air to create an oxygen-rich environment. It oxidizes the iron to converts the ferrous ion into a ferric iron and then the filter strain out the precipitates.

The drawback of this system:

  • The produced ferric iron is sticky, which may cause clogging in the system.
  • You know only 20% of oxygen exists in the air. So not all iron will be oxidized.

How to Remove Ferric Iron in Well Water

By using a filter system with sub-micron rated sediment filter, you can get rid of ferric iron from well water.

Sediment filter lets the water flow through it while preventing iron precipitate that has emerged from the iron well water.

Make sure the filter has a sub-micron rating to capture the ferric iron adequately.

However, it won’t be useful if your well water has ferrous iron along with ferric iron.

How to Remove Bacterial Iron from Well Water

Shock chlorination method is perfect for removing bacterial iron from well water. This method involves three stages: Chlorination, Retention and Filtration.

It uses a high concentration of chlorine to a well. Thus the process thoroughly sanitizes both the water and the physical well itself.

To remove the excess chlorine in the water, you may need to use filter media using activated carbon.

** Using a filter may not be an effective solution if you’re facing a severe level of water iron problem. Based on the mineral types and contaminants present in your well water, you may need to use filters and softeners combo.
