How to Remove Iron, Manganese, and Odor From Well Water

The first step to learn how to remove iron, manganese, and odor from well water is to understand a little about where iron comes from and the types of iron found in well water. Iron is one of the earth's most plentiful resources, making up at least five percent of the earth's crust.

There Are Four Main Types of Iron Or Conditions in Which Iron Is Found in Well Water1. Soluble "Clear Water" Iron 2. Insoluble Oxidized "Red Water" Iron 3. Organic Iron 4. Iron BacteriaUse Home Tests to Find Out What'S in Your WaterThe best way to find out is to do a water test of the water right from the well before it enters the house. If this is not possible, then run the w...Do A Quick Physical Inspection of Your Water and PipesIf you are experiencing iron or rust staining, it is important to determine the source, whether from the well water or perhaps from corroding pipes...Check Your Well Pump Flow RateFlow rate is defined as simply how many gallons in one minute can be pumped from the well.
