Recommended for iron speciation testing to determine the oxidative state of iron in a drinking water sample. Knowing the form of iron in water can help you choose effective filtration or treatment solutions.

Ferrous iron (soluble iron) dissolves in water, while ferric iron (insoluble iron) precipitates. Water with mostly ferrous iron may appear clear, while ferric iron makes water appear reddish/brown/orange. In the presence of oxygen, chlorine or other oxidizing agents, ferrous iron will convert to ferric iron–which can then lead to staining on fixtures, tubs and other appliances.

This Tap Score water test package provides all required materials to properly collect and submit a sample for certified laboratory testing. Reported results will include detailed, quantified analysis of ferrous and ferric iron concentrations.


Iron Speciation Water Test

Is this the right test for you?


What our scientists say:

“ In the presence of oxygen, chlorine, or other oxidizing agents, ferrous iron readily converts to ferric iron. This change often occurs as water sits on fixtures, tubs, or appliances and can lead to red or brown stains. "


This is the right test if you:

    • Water tastes bitter or metallic.
    • Water appears discolored, ranging from red to orange to brown.
    • Water is clear, but leaves red, orange, or brown stains.
    • Looking to determine an effective home treatment device.
