Over 25% of the Earth's crust is iron, therefore, it is one of the most common reasons water treatment is needed. Iron will manifest itself in two different forms: Ferric Iron is a suspended solid which will make the water appear colored, ranging from light yellow to bright orange in color or Ferrous Iron which is a dissolved solid and colorless, but if allowed exposure to air, it may oxidize and appear colored, also
Certainly, iron causes the most noticeable problems. It stains fixtures and can require strong chemicals to remove the orange or rust colored stains. Clothes washed in water with iron issues will often turn brown or orange. It can cause the water to impart an unpleasant taste. Iron will build up in plumbing, sometimes to the point of completely blocking the pipes.
Iron is generally measured in parts per million (ppm) or milligrams per liter (mg/l). The acceptable limit in Maine is less than 0.3 mg/L. Even smaller amounts of iron in well water can cause staining on clothes and fixtures and have an unpleasant taste.
After an onsite water test to find out whether it is mostly ferric or ferrous iron, we can treat the water with an Iron Filter, typically. At times, a Softener system is installed instead or both may be needed.
