Side Effects of Water With High Iron Levels

high iron side effects

High iron content in water may not seem like a major concern at first glance, but prolonged exposure can cause serious problems for your health, home, and environment. In this blog, we’ll explore the high iron side effects that homeowners, industries, and municipal systems should be aware of — and what you can do to fix them.


What Causes High Iron Levels in Water?

Iron is a naturally occurring element found in soil and rock formations. When water passes through iron-rich soil or piping, it can absorb iron particles. Common causes include:
  • Corroding pipes (especially older iron ones)
  • Private wells drilled into iron-rich aquifers
  • Poor filtration in municipal or rural water systems
There are two main forms of iron in water:
  • Ferrous Iron (Fe2+): Dissolved and clear in appearance
  • Ferric Iron (Fe3+): Oxidized and visible as reddish-brown particles or stains


High Iron Side Effects on Human Health

Although iron is essential in small amounts, excessive iron in your water supply can cause several health concerns.


Digestive Distress

Consuming water with elevated iron can lead to:
  • Upset stomach
  • Constipation
  • Metallic taste


Iron Overload in Vulnerable Individuals

People with hemochromatosis (a condition causing iron accumulation) are at greater risk when exposed to high iron water. It may contribute to iron overload, potentially affecting the liver, heart, and pancreas.


Bacterial Growth

Iron encourages the growth of certain bacteria (e.g., Gallionella, Leptothrix), which feed on iron and can lead to:
  • Slime build-up in toilets, tanks, and pipes
  • Musty or unpleasant taste and odor
  • Increased biofilm risks in drinking systems


High Iron Side Effects on Plumbing and Appliances

Iron deposits affect more than just your health — they wreak havoc on your home infrastructure.


Pipe and Valve Blockage

Iron particles can build up inside plumbing systems, restricting water flow and increasing water pressure issues.


Appliance Damage

Dishwashers, washing machines, water heaters, and other systems can suffer from scale and sediment buildup, leading to:
  • Reduced lifespan
  • Increased energy use
  • Frequent repairs


Staining

One of the most visible signs of high iron is staining:
  • Orange or brown stains in sinks, tubs, and toilets
  • Laundry discoloration, especially on whites
  • Rust-colored residue on kitchenware and fixtures


Environmental and Aesthetic Concerns

Even when not a health threat, high iron levels can make water unappealing and harmful to the environment.
  • Taste and odor issues: Iron gives water a metallic flavor that’s hard to ignore
  • Aquatic damage: Iron deposits in lakes or streams can suffocate aquatic life
  • Landscape staining: Sprinklers using high-iron water can stain pavement, walls, and grass


How to Test and Identify High Iron in Water

Signs that you may have high iron levels:
  • Reddish-brown stains in the bathroom or kitchen
  • Metallic taste or smell
  • Sediment buildup in faucet aerators
  • Slimy bacterial film in toilets or tanks
To confirm, use:
  • At-home test kits for iron concentration (in ppm or mg/L)
  • Professional water testing services

According to the EPA Secondary Drinking Water Regulations, the recommended iron limit is 0.3 mg/L — higher levels may not pose immediate health risks but are considered undesirable due to aesthetic and operational concerns.


Treatment Options for High Iron in Water

Addressing iron requires a customized solution depending on its form (dissolved or particulate), concentration, and flow rate.


Sediment Filtration

Useful for removing ferric iron (particles). Not effective for clear-water (ferrous) iron.


Oxidation and Filtration

Combining oxidation with media filtration (e.g., manganese greensand, Birm filters) is effective for treating ferrous iron.


Water Softeners

Capable of removing small amounts of iron (<3 ppm) along with hardness minerals.


Reverse Osmosis Systems

Best for residential or light commercial applications with low to moderate iron levels, especially when targeting multiple contaminants.


Advanced Solutions from ADVANCEES

ADVANCEES offers custom-engineered reverse osmosis and pre-filtration systems specifically built for iron-rich water sources. From brackish water treatment to industrial iron removal skids, our systems can be tailored to:
