2021-04-13 · Iron is usually present in all water, although, according to the Wisconsin Department of Natural Resources, rarely in levels that exceed 10 milligrams per liter (mg/1) or 10 parts per million (ppm). The current recommended levels of iron in well water varies slightly by state, but they range between .2 and 1 mg/l. When iron exceeds these levels, the taste and color of the water can be affected, giving water a metallic flavor or odor and a red, brown or yellow cast that can stain

For situations with iron concentrations up to 2 or 3 ppm, typical water softeners (using salt [NaCl] brine for regeneration) are likely to be effective. The sodium resins in these systems actually prefer the iron to the “hardness” elements such as calcium and magnesium.
