• Regenerate catalytic media with a homemade solution of water and diluted chlorine bleach every 6-8 weeks.

Understanding Iron Contamination Types & Their Impact

When you turn on your faucet expecting clean, clear water but instead find a rusty, metallic-tasting liquid flowing into your glass, you're likely dealing with iron contamination.

We've seen how this common well water issue manifests in four distinct forms, each presenting unique challenges.

Ferrous iron is particularly sneaky—it's clear in water but oxidizes upon exposure to air, transforming into that familiar rusty ferric form that stains fixtures and clothes.

Meanwhile, colloidal and organic iron bind with other substances, creating complex filtration problems.

At concentrations often exceeding 10 mg/L in well water—far above the EPA's 0.3 mg/L recommendation—iron doesn't just affect taste and appearance.

It damages plumbing, increases maintenance costs, and potentially impacts health, especially for pregnant women and children.
