5 Harmful Effects of High Levels of Iron in Water

High levels of iron in water can affect more than just the appearance of your water. While iron is an essential mineral for the human body, excessive amounts in drinking water can lead to unpleasant tastes, staining, plumbing problems, and reduced water quality. As a result, identifying and treating iron contamination is important for both your health and your property’s water system.

At Puritech, we provide reliable water treatment solutions that help remove excess iron from residential, commercial, and industrial water supplies. Whether your water comes from a borehole or a municipal source, the correct treatment system can significantly improve water quality.

What Causes High Levels of Iron in Water?

Iron naturally occurs in rocks and soil. As groundwater moves through these formations, it dissolves iron, which eventually enters wells and boreholes. In addition, aging iron pipes and plumbing systems may release iron into the water supply through corrosion.

Common sources include:

• Borehole water
• Well water
• Corroded iron pipes
• Groundwater with high mineral content
• Industrial water sources

1. Health Concerns

Although iron is an important nutrient, excessive amounts in drinking water may contribute to health concerns for certain individuals. High iron levels can also encourage the growth of iron bacteria, which may affect water quality. Furthermore, people with conditions such as hemochromatosis should avoid consuming excessive iron.

Possible effects include:

• Metallic taste
• Stomach discomfort
• Nausea
• Digestive problems
• Increased iron intake for susceptible individuals

2. Skin and Hair Problems

Bathing in iron-rich water may affect your skin and hair.

For example, excess iron can combine with soap, making it more difficult to rinse completely. Consequently, some people experience dry skin, clogged pores, irritation, or dull-looking hair. Soap residue may also build up on bathroom surfaces.

3. Poor Taste and Food Quality

Iron in water often gives it a noticeable metallic taste.

As a result, tea, coffee, and other beverages may become darker and less enjoyable. Vegetables and other foods cooked with iron-rich water can also become discolored and develop an unpleasant flavor.

4. Stains on Plumbing and Laundry

One of the most common signs of iron contamination is reddish-brown staining.

These stains may appear on:

• Sinks
• Toilets
• Baths
• Showers
• Tiles
• Clothing
• Dishes
• Taps

Moreover, these stains are often difficult to remove and can make bathrooms and kitchens appear dirty even after cleaning.

5. Plumbing and Appliance Damage

Iron particles can gradually build up inside plumbing systems.

Over time, this buildup restricts water flow, reduces water pressure, and shortens the lifespan of appliances such as washing machines, geysers, dishwashers, and water heaters. Iron bacteria may also produce a slimy residue that blocks pipes and fixtures.

Signs You May Have Iron in Your Water

Several warning signs may indicate excess iron in your water supply.

Look out for:

• Rust-coloured water
• Metallic taste
• Orange or brown stains
• Blocked pipes
• Reduced water pressure
• Brown slime in plumbing
• Unpleasant odours
• Laundry staining

Therefore, if you notice any of these problems, professional water testing is recommended.
