Some people question whether tap water may be a concern for taste and smell, and that they may contain impurities.
In such a case, the method that has been used for a long time is boiling.

However, there is a theory that boiling water in the wrong way increases harmful substances.How do you drink tap water deliciously?
This time, I will explain in detail the safety of tap water, boiling methods, and the precautions of boiling water.

Is Japanese tap water safe enough to drink as it is in the first place?First, I will explain the safety of tap water.

Japanese tap water is surprisingly beautiful and safe for foreigners.Japan has a unique water supply law law from around the world, and based on this, it is managed by strict standards.

The “water quality standard for 51 items” according to the provisions of Article 4 of the Water Supply Law must be observed, and chlorine is disinfected to protect tap water from pollution of pathogens and the like.* 1 * 2

In addition, a goal for maintaining safety, "27 water quality control target setting items" are also set.* 1
Thus, Japanese tap water is protected by many standards.

Chlorine has an oxidative effect other than the disinfecting effect, and when it reacts with organic matter in the water, trihalomethane is generated.* 2

What is stipulated in the water quality standard
Chloroform
Bromoji chloromethane
Ziblomochlomethane
Bromoborm
There are four types.

In addition to the above, 58 items were set as a target pesticide list for pesticides, one of the water quality control target setting items, in the 4th year of Order.※Five

These four types of concentrations are called "total trihalomethane".※Four

Chlorine, total trihalomethane, and four trihalo methane remaining in tap water also determine the standard value by 51 water quality standards.The residual chlorine must be 1 mg/ℓ or less, and the total trihalomethane must be 0.1 mg/ℓ or less.* 1

In a water purification plant that cleans water, trihalomethane is reduced by processing using activated carbon and ozone.* 2
With this kind of effort, safe tap water is supplied to your home.

Japanese tap water is managed under strict standards, and there is no problem in health at all.However, some people are drinking tap water and drinking because they are worried about the smell of chlorine and want to reduce impurities as much as possible.

On the other hand, there is a question that tap water may increase the risk of boiling, but which one is correct?In this paragraph, I will explain that question.

When tap water is boiled, it can be removed because the residual chlorine and trihalomethane evaporate.This is because these components have the property of being able to vaporize by heat.
Note, however, that if the time of boiling is incorrect, the phenomenon will increase the number of trihalomethane.The reason for being called "boiling tap water is dangerous" is that trihalo methane may increase in this way.

The appropriate time is important when boiling tap water.So, next, I will explain the correct boiling time.

The residual chlorine can be removed with about 5 minutes of boiling, but avoid stopping the heat in 5 minutes after boiling.This is because there is a possibility that trihalo methane is increasing in the water.

Trihalomethane has the property of increasing as the water temperature rises.Just before boiling, there is a study that it will increase by about 1.0 to 3.6 times before heating, so let’s heat it for at least 10 minutes after boiling.
Even if you make a mistake, do not turn off the fire in 5 minutes after boiling.It is safe to heat it for more than 10 minutes to remove the trihallomethane sufficiently.* 6

When tap water is boiled, chlorine and trihalomethane in the water can be removed.If you boil it with 10 minutes as a guide, you can use it with confidence not only for drinking water but also for making milk for baby.Here, let’s check the benefits of boiling tap water again.

I used to hear voices saying, "The urban water is smelled and cannot be drunk."The cause was that there were many impurities contained in water and raw water that were the source of tap water.Depending on the amount of impurities, the amount of chlorine used for disinfection was large, resulting in a strong carty smell.
At present, chlorine concentration is significantly reduced due to the progress of water purification treatment technology.But still, the smell of chlorine is worrisome.

It is boiling to solve this smell problem.If you boil water and reduce the smell of culches, the flavor of drinks such as tea and coffee will be further enhanced, and it will not affect the taste and aroma of the dishes.In addition, the number of trihalomethane, which is considered to be carcinogens, is also reduced, so it is a great advantage for health.

Japanese tap water is highly safe, so there is no problem to give tap water to your baby.However, babies are less resistant than adults and have underdeveloped body organs, so it is natural to be careful about drinks and food.If you feel that it is reluctant to give tap water as it is, or you want to definitely drink safe water, use the well -boiled water.

Boiling can not only remove chlorine and trihalomethane, but also sterilize.* 7
In the first place, the method of making milk recommended by the World Health Organization (WHO) is to use the completely boiled water before using it.* 8
If you are worried about safety, use water that is boiled for babies and baby foods.

Boiling tap water has the benefits of not only ingredients but also taste and safety.However, boiled tap water has a feature that must be paid attention.If you treat it incorrectly, it may adversely affect your health, so be sure to check it out.

As mentioned above, residual chlorine and trihalomethane cannot be removed in a short boil.The residual chlorine can be removed by boiling for more than 5 minutes.Trihalomethane can increase for more than 10 minutes, as it may increase.Considering both of these, try to boil the water for at least 10 minutes.

Ideally, the boiled water should be used up immediately.The reason is that the removal of chlorine has no sterilization effect, making it easier for germs to grow.The taste and quality of water also decrease over time.Consume as soon as possible.

Bacteria may grow even at room temperature.If you can’t drink, put it in a clean container and store it in the refrigerator.To prevent the growth of bacteria, keep it cool after boiling and keep it refrigerated.Even if you save it in the refrigerator, use it up that day for safety.

Boiling does not mean that all impurities can be removed.For example, some metals are difficult to remove by boiling, such as lead or aluminum.There is a possibility that other impurities are mixed, so it cannot be said to be "boiled = 100 % safe".

For those who are looking for more safe and delicious water than boiling, use a water purifier is recommended.The water purifier has a dedicated filter, and you can remove impurities that cannot be removed by boiling.

Although the image of the water purifier may be expensive, the water purification water server, which can be used in a monthly fee system, is gaining popularity.

By boiling tap water firmly, chlorine and trihalo methane contained in water can be removed.If you use it safely, heat it with more than 10 minutes.On the other hand, it is important to note that if you boil, you will not be able to remove all impurities.

For families who want to stick to water that is safer than boiling, we recommend the water purification water server LOCCA "Slim-R".
A water server that can remove 28 kinds of impurities, including chlorine, mold odor, and trihalomethane, while keeping the mineral components of tap water as they are.Recently, organic fluorine compounds (PFOS/PFOA), which have become a hot topic, can be removed.

There is no need for installation work, you can drink clean water as much as you pour tap water, and you can always use cold water and hot water.If you want to incorporate highly safe water into your life, why not consider the introduction of LOCCA "Slim-R"?
