Because iron is one of the most abundant minerals in the earth's crust, it is very common in groundwater. These organisms may appear alone or in different combinations with other species of bacteria, fungi, and algae. Activated carbon is usually used as the filter material so the excess chlorine can also be removed. But you may not want to drink it.

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. 2 Iron Bacteria in Wells. The bacteria eats the iron so it is not always possible to see it. A well chlorination is the best method to keep it under control. Bacterial Iron - Slime depositing in toilet tanks or fouling water filters and softeners is a good indication of the presence of bacterial iron. The EPA has not listed iron bacteria as a contaminant. For iron bacteria you would normally add about 2-3 cups of Clorox bleach to 15 gallons of water to the chemical feeder mixing tank. Ralph Morris, M.D., M.P.H., is a physician and preventive medicine and public health official living in Bemidji, MN. These bacteria combine iron (or manganese) and oxygen to form deposits of "rust," bacterial cells, and a slimy material that sticks the bacteria to well pipes, pumps, and plumbing fixtures. Iron Bacteria and Well Treatment. The resulting ferric oxide is insoluble, and appears as brown gelatinous slime that stains plumbing fixtures as well as clothing or utensils washed with the water carrying it. Such treatments have the added benefit of eliminating or reducing pathogenic microorganisms that may also be present in your drinking water. Moreover, iron bacteria contamination can create a water quality environment suitable for disease-causing (pathogenic) bacteria, viruses, and other microbes. This season we offer you a captivating NASA video featuring views of planet Earth and space from the International Space Station. While a low level of iron isn’t harmful in and of itself, iron in drinking water is classified as a secondary contaminant according to the EPA. Effects of iron bacteria in drinking water: 1. You can mix BOTH soda ash and Clorox if necessary in the same mixing tank. Updated You may have to treat with chlorine more than once. Disinfect the well, pump, and plumbing after repairs. Eliminate odors, bacteria and pretreat iron before filtration. Grosser still, the bacteria eat, and excrete, iron. Only a small amount of energy is produced. Iron biofouling generally causes side effects such slight and intermittent sulfide odor, and breakthroughs of red water. Iron Bacteria is a common well water problem in Minnesota. Iron bacteria live in groundwater aquifers and can spread from well to well by the use of contaminated tools during well servicing. Bacterial Iron - Slime depositing in toilet tanks or fouling water filters and softeners is a good indication of the presence of bacterial iron. These are a red, yellow, or orange color to the water; slime on the inner walls of the toilet tank; and a smell that may resemble fuel oil, cucumber or sewage. Iron bacteria are not hazardous to health, but in some cases they cause troublesome well problems. The bad news – they thrive in high iron water because irons is a perfect food source for Iron Bacteria. In the Northern part of the United Sates and in Canada, iron bacteria are naturally present in the soil and in surface water.

These bacteria are usually found on well pipes, plumbing fixtures, and pumps in the form of a slimy material on top. The continuous chlorine injection may hide other bacterial contamination and cause corrosion problems. Both natural sources and human activities can contaminate well water and cause short-term or long-term health effects. The Best Whole House Iron Filter System.

Moreover, iron filters cannot treat iron bacteria in the well water. To be safe, test the water for nitrate and coliform bacteria. The chlorine concentration should be close to but not greater than 200 parts per million (ppm). 3 Iron Bacteria in Well Water: Well Management Program. Because objectionable stains, tastes, or odors may be due to other causes—including sulfate, hydrogen sulfide, or other nuisance organisms like sulfur bacteria—proper identification of chemical substances and microorganisms in well water is the first step, and should be done by a state-certified laboratory. Only place disinfected water in a well for drilling, repair, or priming pumps. A concentration greater than 200 ppm reduces how effective the disinfection is.  Before adding the chlorine solution, the well should be pumped until clear or physically cleaned. Copyright 2021 © Water Quality and Health Council. There are three groups of chemicals people use for this: Pasteurization injects steam or hot water into the well to keep the well water temperature at 60 degrees Celsius (140 degrees Fahrenheit) for 30 minutes. Iron bacteria are small living organisms that naturally occur in soil, shallow groundwater, and surface waters. Water containing organic iron is usually yellow or brown color, but may be colorless. Both the concentration of chlorine and how long the chlorine solution is in contact with the bacteria are important. Swampy, oily or petroleum, cucumber, sewage, rotten vegetation, or musty. More serious problems occur when bacteria build up in well systems. Iron bacteria are most commonly problematic in wells, where water has not been chlorinated. Iron bacteria do not produce hydrogen sulphide, the“rotten egg” smell, but do create an environment where sulphur bacteria can grow and produce hydrogen sulphide. These bacteria can give the water a musty or swampy smell. In the process, they produce deposits of iron and a red or brown slime called a “biofilm.” The organisms are not harmful to humans, but can make an iron problem much worse.
