Iron bacteria, and check out Iron bacteria on Wikipedia, Youtube, Google News, Google Books, and Twitter on Digplanet. In the management of water-supply wells, iron bacteria are bacteria that derive the energy they need to live and multiply by oxidizing dissolved ferrous iron. Bacteria known to feed on iron include Thiobacillus ferrooxidans and Leptospirillum ferrooxidans. Iron bacteria colonize the transition zone where de-oxygenated water from an anaerobic environment flows into an aerobic environment. Since the latter reaction is the normal equilibrium in our oxygen atmosphere while the first requires biological coupling with a simultaneous oxidation of carbon, organic material dissolved in water is often the underlying cause of an iron bacteria population. Iron bacteria produce a sticky slime which is typically rusty in color, but may be yellow, brown, or grey.
A feathery or filamentous growth may also be seen, particularly in standing water such as a toilet tank.
The dramatic effects of iron bacteria are seen in surface waters as brown slimy masses on stream bottoms and lakeshores or as an oily sheen upon the water.
Iron bacteria can be introduced into a well or water system during drilling, repair, or service. Water placed in a well for drilling, repair, or priming of pumps should be disinfected, and should never be taken from a lake or pond.
The well casing should be watertight, properly capped, and extend a foot or more above ground. When pumps, well pipes, and well equipment are repaired, they should not be placed on the ground where they could pick up iron bacteria. Treatment techniques which may be successful in removing or reducing iron bacteria include physical removal, pasteurization, and chemical treatment. Acids have been used to treat iron bacteria because of their ability to dissolve iron deposits, destroy bacteria, and loosen bacterial slime.
Disinfectants are the most commonly used chemicals for treatment of iron bacteria, and the most common disinfectant is household laundry bleach, which contains chlorine.

Before attempting to chlorinate, or doing any maintenance on a well, it is important to disconnect the electricity and understand how the well and water system works.
High concentrations of chlorine may affect water conditioning equipment, appliances such as dishwashers, and septic systems. After the chlorine has been in the well and plumbing overnight or for 24 hours, the water should be pumped out. The resulting ferric oxide is insoluble, and appears as brown gelatinous slime that will stain plumbing fixtures, and clothing or utensils washed with the water carrying it. Groundwater containing dissolved organic material may be de-oxygenated by microorganisms feeding on that dissolved organic material.
Treatment of heavily infected wells may be difficult, expensive, and only partially successful.
Acids are typically part of a series of treatments involving chlorine, and at times, bases. Chlorine is relatively inexpensive and easy to use, but may have limited effectiveness and may require repeated treatments.
Iron filters are similar in appearance and size to conventional water softeners but contain beds of media which have mild oxidizing power. If a concentration of 1000 ppm chlorine is used the pH may be raised significantly and the biocidal effect may be reduced to less than 2 percent for water beginning with an original pH of approximately 8 or higher.
Do not over pump the well during this purging as it can damage the aquifer and increase general well problems. Please help improve this article either by rewriting the how-to content or by moving it to Wikiversity, Wikibooks or Wikivoyage.
Iron bacteria in wells do not cause health problems, but they can reduce well yields by clogging screens and pipes. It is important to use chlorine or another disinfectant if phosphates are used, since bacteria may use phosphates as a food source. Effective treatment requires sufficient chlorine strength and time in contact with the bacteria, and is often improved with agitation.

As the iron-bearing water is passed through the bed, any soluble ferrous iron is converted to the insoluble ferric state and then filtered from the water.
Ideally, the well should be pumped until clear, or physically cleaned before introducing chlorine. The equipment can be bypassed, however, iron bacteria or other organisms may remain in the units and spread through the water system. Continuous chlorine injection into the well has been used, but is not normally recommended because of concerns that the chlorine will conceal other bacterial contamination and cause corrosion and maintenance problems. It is recommended to prepare the chlorine concentration to the proper concentration and with enough volume to not only displace the volume of water in the well but also spread out into the aquifer as well. It may be possible to disinfect the well with higher chlorine concentrations; and if the water storage and treatment units are not heavily infected, disinfect the treatment unit and piping with lower concentrations circulated through the water system. It may be possible to discharge the water to a gravel area, run the water into a tank or barrel until the chlorine dissipates, or contract with a hauler to properly dispose of the water. Several different filter media may be used in these iron filters, including manganese greensand, Birm, MTM, multi-media, sand, and other synthetic materials.
The chlorinated water should be drawn into the household plumbing and remain overnight, from 24 hours to 48 hours.
Pasteurization involves a process of injecting steam or hot water into the well and maintaining a water temperature in the well of 60 A°C (140 degrees Fahrenheit) for 30 minutes. Since the oxidizing action is relatively mild, it will not work well when organic matter, either combined with the iron or completely separate, is present in the water and iron bacteria will not be killed.
