Iron in Your Well Water

Iron is the most common well water problem in SC and NC. It causes orange/rust staining, metallic taste, clogged pipes, and damaged appliances — but it's completely treatable.

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.

Iron in Well Water — FAQ

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.
