Both natural sources and human activities can contaminate well water and cause short-term or long-term health effects. This surface water reachs sooner or later to the well water. The removal of iron from well water first involves identifying the type of iron present in the water supply (ferric, ferrous, or iron bacteria), measuring its concentration in ppm, measuring the pH of the water, and then applying the appropriate method of iron removal, either through oxidation, ion exchange, greensand, or chemical feed. May be more noticeable after the water has not been used for a while. Iron and manganese are naturally occurring elements in the earth.

However, at least 0.3 ppm … The chlorine concentration should be close to but not greater than 200 parts per million (ppm). These non-pathogenic (non-health threatening) bacteria feed on iron and manganese in water, forming red-brown (iron) or black-brown (manganese) slime, … Addressing iron bacteria contamination is usually a job for a licensed well contractor or pump installer. 3 Iron Bacteria in Well Water: Well Management Program.

Activated carbon is usually used as the filter material so the excess chlorine can also be removed. Iron bacteria live by obtaining energy through the oxidation of ferrous iron to ferric iron and utilize the resulting CO2 to create organic molecules for their existence. Because iron bacteria are present in many U.S. soils, they can be introduced into a well during drilling, repair, or service, but the following “good housekeeping” practices can help prevent contamination: As in any water distribution system, prevention is the key to safe, healthy, and great tasting water. Using an Oxidizing Agent + Filter. Iron Bacteria May Help Other Organisms Grow Iron becomes part of their cell walls and the end result is a slimy stringy growth that can be seen in toilet flush tanks. In the case of iron bacteria in mains, the proper remedy is to revise the treatment of the water to remove the iron or, if the bacteria grow because of deterioration of old iron mains, to reline the mains (Section 16.11). They can also line pipes and build up in water a perfect food source for iron bacteria Wide Range Conditions.
