Key Facts
- The EPA secondary (aesthetic) standard for iron is 0.3 mg/L
- Staining can appear at concentrations as low as the 0.3 mg/L secondary standard
- SC and NC coastal plain geology can leach iron into groundwater
- Iron oxidizes on contact with air, producing brown or orange staining
- Iron bacteria can produce a slime that affects well pumps and plumbing
The Solution
Depending on the type of iron present (ferrous, ferric, or bacterial), ClearFlow installs iron oxidizing filters, air injection systems, or chemical feed systems. Treatment capacity is defined by the manufacturer's published specifications and depends on your measured iron level.

Frequently asked questions
Why is my well water orange or rusty?
Orange or rusty well water is caused by dissolved iron (ferrous iron) that oxidizes when exposed to air — forming rust particles (ferric iron) visible in water.
Is iron in well water harmful?
Iron itself is not toxic at typical well water levels, but it causes severe staining, metallic taste, clogged appliances, and can indicate the presence of iron bacteria (which can create health risks).
What removes iron from well water?
Depending on the type and concentration: oxidizing filters (air injection), greensand filters, or chemical feed systems. ClearFlow tests your water first to recommend the right system.
Why does my water smell like rotten eggs and look orange?
This combination indicates both iron and hydrogen sulfide (sulfur) — both common in SC and NC coastal plain well water. ClearFlow can address both with a combined treatment system.
How do I get my well water tested for iron?
ClearFlow offers free in-home well water testing across SC and NC. Call (843) 742-1196 to schedule.
