Whether you want to protect your plumbing or look after your own health, it’s definitely a good idea to test your water for iron. Iron can cause water to taste metallic, and will even affect the taste of the foods you cook in water. Dissolved iron also stains surfaces, such as toilet bowls, bathtubs, plates and cutlery, and even laundry.
How do I get iron out of my water?
Iron OUT can be flushed from the lines by going to the faucet closest to the water softener and allowing the cold water to run. After the odor is gone, turn on other faucets in the home for a short time to make sure the product has been eliminated from all the lines.
What is iron testing in water?
Yellow or red colored water is often a good indication that iron is present. However, a laboratory can tell you the exact amount of iron, which can be useful in deciding on the best type of treatment. In addition to testing for iron, it can be helpful to test for hardness, pH, alkalinity, and iron bacteria.
Is iron in drinking water bad for You?
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. This is because iron often carries with it bacteria that feed off the iron to survive. These small organisms can be harmful when digested.
Can you use iron out in well water?
The bottom line is the iron in drinking water is NOT dangerous but not really ideal in the form it appears in well water. In fact, it’s important to know that Iron is not a contaminant but a natural mineral that comes with the symbol Fe.

What is acceptable level of iron in water?
0.3 mg/lUnder Department of Natural Resources (DNR) rules, iron is considered a secondary or “aesthetic” contaminant. The present recommended limit for iron in water, 0.3 mg/l (ppm), is based on taste and appearance rather than on any detrimental health effect.
How do you test for iron in water samples?
DIY iron test kits will give you an indication of how much iron your water contains in PPM or mg/L. You'll be provided with testing strips and a color chart. Simply dip a strip in a sample of your water, then wait for the strip to change color. Compare the strip to the color chart to work out your water's iron levels.
What causes high iron in water?
Making up at least 5 percent of the earth's crust, iron is one of the earth's most plentiful resources. Rainwater as it infiltrates the soil and underlying geologic formations dissolves iron, causing it to seep into aquifers that serve as sources of groundwater for wells.
What type of iron is found in water?
Iron is mainly present in water in two forms: either the soluble ferrous iron or the insoluble ferric iron. Water containing ferrous iron is clear and colorless because the iron is completely dissolved.
How do you remove iron from water?
Here are the various ways of iron removal from water:Shock Chlorination.Chemical Oxidization.Catalytic Filtration.Phosphate Treatment.Oxidizing filters.Water Softeners.Iron Removal Filter.
How do you remove iron from water?
One method calls for oxidation of the water to convert all the ferrous iron to ferric iron, followed by filtration. The oxidation step can be achieved by chemical injection, catalytic media, or by aeration. Once all the iron is in the ferric state, it can be filtered.
How do you know if you have too much iron in your water?
Signs of High Levels of Iron in Your Water Your water will often have a yellow, brown, or red hue as it flows from the tap. Plumbing Clogs – Iron leaves behind a residue in the form of sludge. High iron levels can quickly clog pipes and pumps with telltale reddish slime.

How is iron content measured?
Measuring Fe Concentration by FAAS Remove 4 mL from each sample for measurement by FAAS. Divide the results obtained from the FAAS measurement by the weight of the ashes. Divide the resulting value by 0.01 (because the ashes were solubilized in 10 mL). The resulting value is the iron concentration per gram ash (ppm).
What is catalytic filter?
Catalytic Filtration: A granular filter medium that enhances the reaction between oxygen and iron and then filters the insoluble iron.
Why does my toilet smell like iron?
When iron exists along with certain kinds of bacteria, a smelly biofilm can form. To survive, the bacteria use the iron , leaving behind a reddish brown or yellow slime that can clog plumbing and cause an offensive odor . This slime or sludge is noticeable in the toilet tank when the lid is removed. The organisms occur naturally in shallow soils and groundwater, and they may be introduced into a well or water system when it is constructed or repaired.
How to solve iron problem in water?
One alternative in solving an iron problem may be to construct a new water well, eliminating the need for treatment. Depending on local land conditions, it is sometimes possible to extend a “well casing” or “screen” deeper into the groundwater and avoid the water with high iron levels. An Illinois licensed water well contractor, knowledgeable about the quality of groundwater, can be contacted to discuss options.
What happens when iron is low?
Concentrations of iron as low as 0.3 mg/L will leave reddish brown stains on fixtures, tableware and laundry that are very hard to remove. When these deposits break loose from water piping, rusty water will flow through the faucet.
What is manganese greensand?
Manganese Greensand: A naturally occurring mineral or manufactured material, treated with potassium permanganate that is capable of removing iron; it absorbs dissolved iron and requires chemical regeneration.
What is the color of water with iron?
Organic iron occurs when iron combines with an organic acid. Water with this type of iron is usually yellow or brown, but may be colorless. As natural organics produced by vegetation, tannins can stain water a tea color. In coffee or tea, tannins produce a brown color and react with iron to form a black residue. Organic iron and tannins are more frequently found in shallow wells, or wells under the influence of surface water.
What is the pH of water?
The source of iron may be from the corrosion of iron or steel pipes or other components of the plumbing system where the acidity of the water, measured as pH, is below 6.5.
What is the color of iron?
Ferric Iron. This is iron that has come into contact with oxygen and has oxidized, creating a red rust coloring. If reddish particles drop to the bottom of a glass of water and settle, then ferric ions have been created. Ferric iron is insoluble.

Iron within water is often visible, as are the problems it can cause over time. Reddish rusty spots, sludge within your toilet or reddish debris at the bottom of a glass of the well water is a clear sign of iron being present in the water. Also, if you run a faucet and the water coming out is any shade of red or brown then it can be a clear sign ...
What is a whole house iron filter?
A whole house iron filter can treat all of the water being used within the home at the point it enters. If ferrous iron is present at over 10mg/L, an oxidation agent can be added to the water, which can be held in a retention or pressure tank while a pump triggers a chemical reaction, causing the iron to precipitate.
What does it mean when your faucet is red?
Also, if you run a faucet and the water coming out is any shade of red or brown then it can be a clear sign of iron being present. There are lab tests available which allow you to send off a sample from your well and get it tested for the exact content of iron, and which type of iron is within. Finding local companies can be as simple as looking in ...
Where does ferrous iron come from?
Ferrous Iron. Ferrous Iron is clear to look at, it comes from water supplies with no oxygen in them such as deep wells and groundwater. Carbon dioxide turns this to ferrous bicarbonate, which is soluble, as opposed to ferric iron.
What factors should be considered when treating iron?
Other factors to be considered include the pH of your water and even the type of well system in place .
Can iron be treated with a softener?
Ferrous iron can be treated by a softener, but ferric iron can slip through. If you have over 7 pH then a specific iron filter, which has a different process to a softener, will be needed to get rid of the iron. These will usually involve Birm or Filox materials which can filter iron, but not other minerals such as calcium.
How does iron affect plants?
Green plants apply iron for energy transformation processes. Plants that are applied as animal feed may contain up to 1000 ppm of iron, but this amount is much lower in plants applied for human consumption. Generally plants contain between 20 and 300 ppm iron (dry mass), but lichens may consist up to 5.5% of iron. When soils contain little iron, or little water soluble iron, plants may experience growth problems. Plant uptake capacity strongly varies, and it does not only depend on soil iron concentrations, but also upon pH values, phosphate concentrations and competition between iron and other heavy metals. Limes soils are often iron deficit, even when sufficient amounts of iron are present. This is because of the generally high pH value, which leads to iron precipitation.
What happens when chelation ligands are absent?
When chelation ligands are absent, water insoluble tertiary iron hydroxides precipitate. This is not thought to be hazardous for aquatic life, because not much is known about hazards of water borne iron. Mollusks have teeth of magnetite of goethite. Green plants apply iron for energy transformation processes.

These are also applied in wood impregnation and photography. Aluminumwaste products containing iron were discharged on surface water in the earlier days.
Why is iron removed from water?
Iron removal from water is mostly carried out in drinking water preparation, because mineral water contains high amounts of iron ions. These influence water colour, odour and turbidity.
What causes rust in a well?
The casings and pipes leading to and from the well are likely made of iron. When they are exposed to water and oxygen the iron can begin to deteriorate, causing the iron to oxidize, and form the natural by-product rust. As water travels through the pipes the rust flakes off into the water supply and subsequently into your tap and appliances.
What is the maximum amount of iron in well water?
As mentioned earlier, the EPA lists Iron as a Secondary Drinking Water Contaminant with a maximum contaminant level of 0.3 mg/L. According to the Minnesota Department of Health, “a milligram per liter is approximately equal to 1 part per million (ppm).” Having levels above .3ppm of iron will increase the likelihood of seeing damaging side effects to your appliances, clothing, dishes, and food.
What happens when iron is exposed to water?
When they are exposed to water and oxygen the iron can begin to deteriorate, causing the iron to oxidize, and form the natural by-product rust. As water travels through the pipes the rust flakes off into the water supply and subsequently into your tap and appliances.
What happens if iron is stagnant?
Once stagnant, the iron is able to accumulate inside the pipes of your water supply system as well as your appliances. This can result in the need for expensive repairs in your dishwashers, washing machines, sprinklers, and other water-related appliances.
Why does ferric end in I-C?

What color is iron in well water?
The stain will appear in a red, yellow, or brown color making all of those items look gross and unsanitary no matter how hard you try to clean them.
How to treat water with iron?
Treatment of irrigation water containing excess iron involves precipitating the dissolved iron before it reaches your irrigation system. This can be accomplished by oxidizing iron via aeration, and/or raising the pH of your reservoir to at least 7.2 with hydrated lime or running water over a bed of crushed limestone. Filtration is sometimes required to prevent clogging of irrigation equipment if precipitated iron does not settle to the bottom of the reservoir and is taken in to the irrigation lines.
What does the color of the water mean in golf course irrigation?
The color of the water indicates a high iron concentration, which may be of concern to the superintendent with respect to negative effects on the irrigation system and other cosmetic problems. Although I was quite certain there was a high amount of iron in the sample, the lab results indicated below-normal levels of iron (<0.01 ppm).
Does iron affect irrigation?
Although many labs consider >5 ppm of iron undesirable in irrigation water, this does not mean it will harm your plants and soil. In fact, turf and soil problems due to high iron concentrations in water are rare. Potential problems due to high iron in irrigation water mostly center around staining of concrete surfaces; plugging of irrigation equipment and drainage tile; as well as unsightly deposits of rust-colored material on ornamental plants. High iron concentrations in spray tank water can clog screens and nozzles, and negatively affect performance of some pesticides. If concentrations are exceptionally high, and iron-laden water is used frequently and continuously, some nutrient deficiencies may result.
