Shock chlorination; consider following with continuous chlorination. A well chlorination is the best method to keep it under control. Bacterial iron may build up quickly compared to mineral encrustation. The bad news – they thrive in high iron water because irons is a perfect food source for Iron Bacteria. 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. (952) 767-0230 - Local Minnesota Service - … Ferrous … Effects of iron bacteria in drinking water: 1. And the more they eat and excrete, the more slime they produce which forms large, gelatinous, slimy colonies in your well. A classic example of a rusty-looking tank resulting from water affected with iron bacteria. Iron Bacteria in well water is a common problem in Illinois. By Ralph Morris, MD, MPH, and Stephen A. Hubbs, PE. The EPA has not listed iron bacteria as a contaminant. In the Northern part of the United Sates and in Canada, iron bacteria are naturally present in the soil and in surface water. Iron bacteria are bacteria that derive the energy they need to live and multiply by oxidizing dissolved ferrous iron. And the more they eat and excrete, the more slime they produce which forms large, gelatinous, slimy colonies in your well. Only a small amount of energy is produced. Sticky rusty, yellow, brown, or grey slime. To determine the best treatment option, it’s best to get the water tested. Iron bacteria thrive in water containing high levels of iron and can accumulate in appliances and plumbing to create sludge, biofilm, and foul odors in water. From the ugly stains and discolored tap water to nasty iron bacteria in the toilet tank, iron is one of the most common complaints our water treatment experts around the country are asked to fix. Some people have used continuous chlorine injection into the well, but the Minnesota Department of Health does not usually recommend this. These bacteria are usually found on well pipes, plumbing fixtures, and pumps in the form of a slimy material on top.

Steve Hubbs, P.E., retired from water treatment operations at the Louisville Water Company in 2004, but remains an active volunteer in the drinking water community. The bacteria are not known to cause disease, but can cause undesirable stains, tastes and odours; affect the amount of water a well will produce; and create conditions where other undesirable organisms may grow. Because iron is one of the most abundant minerals in the earth's crust, it is very common in groundwater. 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. Minnesota Department of Health. If left unchecked, biofouling can clog pump intakes, well screens, filters, and water pipes. The bacteria feed on iron and manganese in water. Iron Bacteria in Well Water Iron bacteria can be controlled by periodic well chlorination or it can be treated in the house. Sources of Iron and Manganese in Drinking Water. Never use water taken from a lake or pond. https://www.whitehouse.gov/sites/default/files/pcast_drinking_water_final_executive_summary_final.pdf, https://www.michigan.gov/documents/deq/odwma-eh-wcu-ironbacteriainwells_529560_7.pdf, http://www.health.state.mn.us/divs/eh/wells/waterquality/ironbacteria.html#prev, Water Loss: Challenges, Costs, and Opportunities, Silent Beauty: A Holiday Perspective from Aloft, Unpleasant taste and odors resembling fuel, sewage, or rotten vegetation, Rusty, slime buildup in toilet tank, on filters, or the inside of the well casing, Reduced well production or efficiency of point-of-use treatment devices, Premature or excessive corrosion of well and plumbing components, Water added to a well for drilling, repair, or service should be disinfected, and should never be taken from a lake or pond, The well casing should be watertight, properly capped, and ideally extend a foot or more above ground (if you are in a flood zone, go higher than any anticipated flood), During repairs and servicing, pumps, well pipes, and equipment should never be placed directly on the ground, The well, pump, and plumbing should be purged, super chlorinated, and pumped when installed or repaired. 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.
