Iron in water from a well: what to do about it

Iron in water from a well: what to do about it Water from the well smells of iron - what to do

Not every private house has a centralized water supply ... If everything is easier with apartment buildings, then not all private buildings and country houses are capable of boasting a water supply system. But, such owners do not do, they have to get drinking water on their own.

This requires a well or a well, and it is these water sources that help out.

But how safe is it?

General information

But guarantees that every groundwater is fully safe, simply not. After all, no one can argue with the fact that there can be even heavy metal ligatures in ground water. The most popular of these has become iron. Quite often you can hear such a question - what to do if water from a well contains iron? It is to this question that we will try to answer fully, and then we will consider the permissible standards of iron that are in drinking water, what is fraught with a high concentration of iron for the human body and how to deal with this problem.

How much iron should be in water

It is a popular fact that iron is the element that is even required for the functioning and vital activity of the human body. After all, it is the blood of an adult that has 5 grams of iron in it. The peculiarity of such iron is that it is terribly excreted from the body, and this process is quite slow. For example, the intestinal wall can remove no more than 10 mg of iron per day. Because of this, data have been created that say that for a male, the permissible iron rate in 24 hours is from 6 to 10 mg.

And if we talk about women, then the norms for them are slightly higher. This is due to additional heat losses.

For this reason, the daily intake of iron is between 12 and 18 mg. Based on the data, the conclusion will be that it is quite simple to calculate the ideal amount of iron that is in water. Since a person needs to drink about 2 liters of water per day, it is very easy to understand what percentage of iron is allowed.

But there is another problem - water is not one source of such an element as iron, which we take in 24 hours. You will be surprised that most of our iron (90%) comes from food.

Please note that…

… there is a huge iron content in meat, legumes, liver, seafood and apples.

What else needs to be said about the permissible rate of iron in water? In fact, the World Health Organization has never been able to figure out a specific ratio of the percentage of such metal in a liquid. According to experts from certain organizations, data that could testify to the negative effects of iron on the human body are not collected in full.

But there is a sanitary norm, which will state that the presence of iron in water should not be more than 0.3 mg per liter.And the funny thing is that it was established not by the criteria of medicine, but by the quality of taste.

The daily intake of iron, which is permissible for humans

Despite all of the above, the WHO studies were not in vain, and they helped determine exactly how much iron in the water a person able to transfer. According to information from the PSP (that is, the tolerated daily consumption level) will be equal to 0.

8 mg per kilogram of mass per day. This will make it possible to make certain calculations. For example, let's take an average person who weighs 75 kg, namely, his weight makes it possible to consume no more than 60 mg of iron per day. But this is when he will not eat, but only drink water. This is not possible, since we get only 10% of iron from water, and 90% of food, then the permissible norm for the concentration of an element in water is from 2 to 3 mg per liter.

According to experts from the World Health Organization, a person who consumes water with an iron content of less than 3 mg per liter will not feel different changes in the body. Although there is a huge minus here - even if the liquid is not harmful, it will be pleasant to drink it, because it does not taste the best. When your water from the source has such indicators or more, you will need to do something about it.

How iron can affect human health

If there is a lot of iron in the water from the well, then it is required to purify the water, as well as to understand the consequences of taking such water for food. No one will even deny that health is the most precious thing you have.

For this reason, no one wants to make it worse on purpose. What happens if the water contains more than 3 mg iron per liter?

Please note that a one-time intake of liquid with a huge concentration of iron does not affect health in any way. It will be about the constant consumption of this water from your well.

To begin with, iron oversaturation can lead to the replacement of other nutrients, namely calcium, copper, zinc and others. This will carry the rest of the problem.

Here is a list of all the ways that can happen to the person who will drink this water from the well:

  1. Iron in water from a well: what to do about it The liver will begin to grow in size.
  2. Memory gradually deteriorates, as does concentration.
  3. Skin will become irritated and unpleasant to touch. The skin and mucous membranes may begin to turn yellow.
  4. The composition of the blood will change slowly but surely due to the iron in the water.

  5. A person begins to lose weight, become pale, quickly overwork and become weaker.
  6. Heart rhythm is abnormal.
  7. Not without indigestion and inflammation of the digestive organs in general.
  8. Thyroid gland malfunction.

Given the fact that the body barely removes iron, daily consumption of such water can lead to the deposition of the element in the most important organs of the body.

The liver, kidneys, intestines, heart, pancreas and lungs - they will first of all begin to suffer from an excess of iron. By the age of 50, a person will eventually acquire nervous pathologies, terrible mental activity, diabetes mellitus and poor joint work. If your well or well has such water, you need to do something about it. How to determine the level in general? Let's see.

Allowable amount of iron

The source of metal in water is iron ore (magnetic, brown and red).

To understand that water with a huge iron content will turn out to be to your taste, but it is much more effective to do it in a laboratory. To do this, it is important to collect fluid from the well and take it to the laboratory that is engaged in such work. Naturally, such a procedure is not free, but when it comes to health, you can not spare money. This will help you decide on a way to fight. And for the analysis to show real data, you are required to follow certain rules when collecting water from a well.

Good advice! This analysis procedure, the owners should do when they just dug the well. This is mandatory, and as for users who have been using a water source for a long time, they need to do this constantly, every couple of years. But if necessary (unpleasant taste and turbidity of water), this can be done at any time of the year.

There are also certain indirect signs that speak about an increased level of iron in water. The main thing is the taste, and after taking water, an unpleasant aftertaste of metal will remain in the mouth, and this is a clear signal of a huge amount of iron.

The second telltale sign will be the color of the water, and it will be closer to yellow and brown, but not clear. Although everything will depend on the form of iron content. And you can also notice a rusty coating on metal utensils, and with such signs, you may not even enter the laboratory. Now that everything is clear, it is time to start solving the problem with the high iron content in the well. It is impossible to live without it, and drinking such water is extremely dangerous.

Let's consider two methods for solving this problem.

How to solve the problem?

Use of a filter to purify water from iron

Purification of water from iron from a well can be carried out automatically, without the participation of people ... But this will require spending money, and although, as we said, you cannot buy health for any money.

For this reason, the purchase of a reverse osmosis filter for the source will be very justified. Naturally, there is nothing to be done with the well. But iron can be removed from the water. An alternative would be to install ion exchange cartridges. They are installed at the place where the pipeline enters the house.

The inner walls will be coated with an oxidizing compound, which means that as water passes through the cartridge, the iron will begin to react at a chemical level. Most often, the well will contain ferrous iron. This chemical reaction forms a solid precipitate that will settle on the water filter.

Please note that after a while the water filters will start to get clogged and not filter the water as well. For this reason, you will be required to regularly replace the cartridges.

Usually their resource is indicated on the packaging or by consultants.

But the most effective way of fighting will be an increased level of iron in the water from the well - installation of an expensive reverse osmosis system. It is made of three or more filters. In addition, they are equipped with a semi-permeable membrane that filters the water. The advantage of such a filter is that it can clean the liquid not only from iron, but also from other negative additives.

The output will be perfectly clean water.

Interestingly, if ferric iron is also eaten in the well, then filters will need to be replaced much more often. This causes certain difficulties and additional expenses.

Another way would be a water aeration system. It is used to remove ferric iron.

The aeration system is a large open reservoir in which water is stored and settled for a long time. This is required for the oxidation and precipitation of iron. And to speed up the process, air will be passed into the water tank by means of a compressor. The output is good water with a minimum percentage of iron. It is recommended to use such a system at a metal concentration of 10-20 mg per liter.

Purify the water from iron with your own hands

If such options for water purification seem expensive to you, then there is an alternative, that is, very simple struggle against high iron content. They are more affordable and able to reduce concentration to normal levels. We can say that the methods, in fact, will be based on the previous ones. For example, the aeration method is carried out on a smaller scale with a conventional bucket. All that is needed is to draw water from the well, leave it to weed out for a day.

So time will do its job.

Iron under the influence of oxygen begins to oxidize and settle at the bottom. You will need to carefully drain the top layer without stirring up the sediment.

This inexpensive and simple method makes it possible to reduce the concentration of iron in water by 4 times. But these are not all the options, you can resort to the following tricks:

  1. Iron in water from a well: what to do about it Freezing water is a simple and not expensive, and you only need a freezer with a bottle.

    It is enough to fill the plastic container with water and freeze it. Then wait until most of the water turns into ice, and drain the rest. It is he who will collect in himself all the negative elements, and when defrosting the rest of it, you will need to throw out ice, which will be the last.

  2. Use of silicon and shungite - the material has the property of water purification and disinfection. It is enough to lay them on the bottom of the container with water, and then stand the water for 2 days and drain only the top layer, and sediment will remain from below.

  3. Simple coal - everyone knows about the filtering ability of coal, and it copes effectively with water purification. You get a certain analogue of the filter with your own hands, and it is enough to take it by the coal, wrap it in a thick layer of cotton wool and pass water through it.

All methods are effective, and therefore use them if there is iron in the water from the well. Which one to choose is up to you, and you can experiment and combine them to find out which one works best.


Water is extremely important, and therefore we should pay special attention to it, what kind of water we drink.

The water quality must be good, and therefore the owners of wells and wells need to constantly monitor the composition. High iron content will not improve health, it will even make it worse. For this reason, you need to think about the methods of struggle and draw conclusions, and then water will not be the cause of deterioration in your health.
