Iron and Manganese Treatment

A reddish-brown staining indicates a significant amount of dissolved iron in the water while a blackish color indicates manganese.

Treatment:

Small amounts of dissolved iron (and/or manganese) can be removed with a common water softener. The water softener manufacturer should have several models that list the amount of iron removal in grains per gallon.

High amounts of dissolved iron (and/or manganese) can be removed using a properly rated iron (and manganese) treatment device. Cartridge type devices are available to remove amounts of iron (and manganese) less than 5 milligrams per liter (the same as 5 parts per million).

NOTE:  Have your water tested by a certified laboratory prior to purchasing equipment. The Water Quality Interpretive Tool can help you determine how your water quality compares to EPA guidelines and what treatment options are available.

Always have your water tested and base any treatment on those results. Our Water Quality Interpretation Tool will aid you in your decisions.
