Why can t tap water be drunk directly? What are the hazards?

Although tap water has been sterilized with chlorine, we know from our "Chlorine Test for Tap Water" that chlorine (bleaching powder) is a substance that forms chloroform and other carcinogenic and teratogenic substances when boiled.

The use of chlorine to disinfect tap water has long been strictly prohibited in this developed country. And from the waterworks to our homes through the long pipes and high-rise water tanks, the tap water has suffered from secondary pollution, some high-rise building water tanks are not closed and covered, not cleaned for a long time, soaked dead rats are bigger than cats.

CCTV life column also reported: "When will the water tank pollution stop", take 10,000 steps back and say, even if our tap water is not polluted, it also meets China's drinking water standards, but you can know that "China's drinking water standards are 20 years behind developed countries" Such an unavoidable fact.

Can tap water be drunk directly?

Tap water contains sedimentants and other harmful substances to the body, and only hot drinks can decompose those harmful substances.

The purity of the tap water after being treated in the factory is still quite high! Mainly in the process of circulation, as most water pipes have sediment. Microbe.

Bacteria or something, contaminating the treated water. People who drink it directly are prone to diarrhea. Hurts the stomach and intestines.

It is recommended to boil before drinking. However, it is not possible to boil the water repeatedly.

Generally speaking, the purity of the treated water is very high, but in the process of its circulation, sediments and microorganisms in the water pipes will enter, and people are prone to stomach upset after drinking, which will damage the stomach and intestines in the long run...

Now tap water is becoming less and less substandard, and there are a lot of microorganisms and bacteria in it.

Chlorine-disinfected tap water will contain chlorine and other harmful chloride residues.

Yes, and it will not be harmful to the body, and drinking more water can also enhance immunity and relieve the phenomenon of sore throat. It can also beautify and promote intestinal peristalsis.

1. Tap water can be boiled and drinkable: after the tap water is disinfected, it can reach the standard of direct drinking water, and the tap water also has a sterilization effect after heating and boiling, which basically kills bacteria and microorganisms, and can be used for people to drink directly after cooling. However, it is recommended to drink tap water on the same day after boiling, because if it is left for a few days, it may breed microorganisms or fall into dust, which can have adverse effects on the body; 2. Tap water should not be boiled and not drinkable

If there is a problem with the water quality due to the aging and rusting of the pipes transporting tap water, or the pollution of the water source, it is not recommended to drink the tap water after boiling. In addition, if the local water quality is hard and there is white sediment in the tap water, it is not recommended to drink it for a long time to avoid adverse effects on the body. Those who have conditions can buy pure water, mineral water, or choose a water purifier to purify the water and then heat it for drinking.

Of course, you can drink it, tap water is not harmful to the body, because tap water is filtered, so you can drink it directly, and there is no bad effect on the body.

Tap water is absolutely not directly drinkable, most of the tap water is above-ground water, after treatment and then sent to thousands of households, treatment will inevitably put some drugs that can purify water quality, the microorganisms in the tap water can not be killed, and drinking raw water is easy to make a stomach, so tap water must be boiled to drink, or the purification treatment measures of home water, drink later.

It is best not to drink tap water directly. Because tap water is generally supplied through a long underground pipe network, there may be water pollution in the middle, and long-term drinking may cause a huge burden on the kidneys and liver, and even heavy metal poisoning.

No, it will have a certain effect on the body after drinking, and there are certain parasites or microorganisms in these tap water, which will lead to some chronic diseases, and can also lead to abdominal pain and bloating.

Tap water is not drinkable. Chlorine is generally used for water purification, and there will be residues in tap water, which will cause cancer if you drink it directly for a long time.

No, long-term use will lead to chronic poisoning, and there will be frequent delusions of wanting to urinate, the body feels uncomfortable, etc., which is not conducive to the healthy development of our body, and will cause great harm to the body, and consequences.

Can tap water be drunk directly?

1. Normal tap water cannot be drunk directly. The water produced by the waterworks is a combination of oranges and drinking standards. However, this does not indicate that it is standard drinking water.

2. There are two reasons:

3. (1) Although the purification of water with chlorine in the production process can kill harmful substances such as pathogenic microorganisms, the addition of chlorine itself can cause new chemical pollution. Chlorine can be combined with organic matter in water to form chloroform, which is a carcinogen. At the same time, chlorine also destroys nutrients and can easily lead to heart disease.

4. (2) In the pipe network of tap water, long-distance pipeline transportation, old and rusty pipelines, urban high-rise water tanks and building reservoirs are not clean or used all year round without disinfection, which can cause secondary pollution. Secondary pollution causes bacteria, viruses and algae to multiply, plus the original chlorine and chloride, rust, heavy metals, radioactive substances, make the water turbid, have a peculiar smell, and its harm is endless.

5. Therefore, tap water is not standard drinking water. In a variety of increasingly polluted environments, we must have strict standards for the water we drink in our bodies.

Tap water refers to the water produced by the tap water treatment plant after purification and disinfection that meets the corresponding standards for people's life and production. Domestic water is mainly absorbed from rivers, lakes, groundwater and surface water through the water intake pumping station of the water plant, which is treated by the waterworks in accordance with the relevant health standards for domestic drinking water, through precipitation, disinfection, filtration and other technological processes, and finally transported to various users through the water distribution pumping station.

Tap water contains a lot of microorganisms and pathogenic bacteria, generally can not be sterilized comprehensively, if not boiled to drink may cause abdominal pain and diarrhea, if often drink it to cause bladder cancer.

The likelihood of developing rectal cancer will increase by 21%.

The probability will be 38%.

People in the city drink tap water, and ordinary water from rivers and lakes is chlorinated after being sent to the waterworks to remove impurities such as microorganisms. But at the same time, chlorine interacts with residual organic matter in water to form toxic carcinogenic compounds such as halogenated hydrocarbons and chloroform.

Studies have proved that the content of halogenated hydrocarbons and chloroform is closely related to the change of water temperature and the duration of boiling. When the water temperature reaches 90, the content of halogenated hydrocarbons rises from 53 micrograms per liter to 191 micrograms, and chloroform rises from micrograms per liter to 177 micrograms, both exceeding the national standard by two times. When the water temperature rises to 100 μg, the content of halogenated hydrocarbons and chloroform drops to 110 micrograms and 99 micrograms respectively, which still exceeds the national standard.

If it continues to boil, after 3 minutes, the halogenated hydrocarbons and chloroform levels drop to micrograms and micrograms, respectively, and it becomes safe drinking water.

Because the tap water of the Wa Kingdom only meets the standard of use. The criteria for direct drinking are not met. Therefore, raw water has bacteria, and drinking it directly can easily cause adverse reactions such as diarrhea.

The improvement of health awareness and the pursuit of quality life have made more and more people pay attention to the water quality at home. Although there are strict standards for tap water produced by waterworks, when it comes to the end of the family, stepping on the tap water line makes many families feel anxious about drinking water.

Is tap water drinkable? Will the water at home be hard and easy to get stones if you drink it? The ensuing problems have led to the search for better solutions for drinking water in the home.

Can you drink tap water?

It is not difficult for everyone to find that there is a disinfectant water smell in tap water, in order to ensure that the tap water flows to the terminal when not to let the bacteria and viruses "along the road" take advantage of it, usually add a certain amount of chlorine to the tap water when leaving the factory for disinfection, the state has regulations on the amount of residual chlorine in tap water, and the national standard stipulates the residual chlorine content of the factory water, that is, the residual chlorine per liter must be at least contained to meet the standard.

So while residual chlorine does affect the taste of tap water, its presence is necessary. As long as it meets the standards and there are no pollution incidents, the tap water at home can be drunk after boiling. If you are concerned about residual chlorine, you can open the lid and let the water boil for a few more minutes.

It's just that the taste of boiled tap water is really not good.

Will the water at home be hard and easy to get stones if you drink it?

In some areas, the water quality of tap water at home is hard due to the influence of water sources, and many people are worried that drinking such water is prone to stones. In fact, the hard water quality is mainly due to the high content of calcium and magnesium ions in the water, and the hard water has some negative effects on daily life, such as kettles, water heaters and other electrical appliances are easy to scale, bathroom glass is prone to water stains, and clothes are hard and yellow after washing, ......However, in fact, there is no data to prove that drinking hard water will increase the risk of stones.

The new situation of household drinking water.

In general, tap water is ready to drink when boiled, but it is inevitable that tap water will taste worse when boiled. If you want to make the quality of household drinking water more secure and greatly improve the taste of tap water, then you can solve it through household reverse osmosis water purifiers.

Reverse osmosis water purifiers are usually installed under cabinets, and through RO reverse osmosis technology, tap water can be filtered into purified water, which tastes no different from most bottled or bottled water on the market.

If the pipes in the old community are aging and the tap water quality is poor, there will be visible sediment and rust from time to time, in this case, a pre-filter can be added to the household entrance to filter the water of the whole house, and the reverse osmosis water purifier at the back end can be protected. The pre-filter does not need to be replaced, and it can be flushed regularly.

For people with little life experience, there must be many questions in life, such as tap water can't be drunk directly without treatment, apples can't be eaten directly without washing, but apples washed with tap water can be eaten directly, what is the reason? And from childhood to the elderly, we are told that tap water cannot be drunk directly, why is that? <>

The tap water in our life is simply poisoned with chlorine, and its health indicators do not meet the standards of drinking water, that is to say, the tap water still contains a lot of microorganisms or bacteria, and drinking it directly may affect human health, so before you want to drink tap water, you should boil it, and most of the microorganisms will be eliminated after boiling. Secondly, chlorine disinfection tap water will make the tap water have chlorine or chloride and other toxic substances residues, drink it directly, these toxic substances will be directly absorbed by the human body, and there is no need to consider problems such as boiling tap water, because chloride and other toxic substances in the boiled tap water will be volatilized. <>

The water pipes for tap water and the water pipes for drinking water are not the same for both standards. The water pipe of tap water is very easy to cause pollution in the process of transporting tap water, and the water resources of tap water are not too strict restrictions, the quality of water resources will have a relatively big problem, there may be many microorganisms in it, even if some people say that tap water will be treated by the water plant, but that can not all eliminate microorganisms. But if the tap water installed in your home is drinking water that meets the national qualified standard, then the tap water is drinkable.

But this probability will be relatively small, and some drinking water institutions in China can not completely guarantee that the tap water they install can be drunk directly, so it is safer to boil the tap water and drink it again. <>

In addition, there are many problems in the water supply system of tap water, if the water supply system of tap water is aging, then the tap water may contain rust or parasites, which can not be directly drunk into the human body.

This is because there are still a lot of microorganisms in tap water, which will cause serious gastrointestinal stress after entering the human body, affecting people's health, and need to be boiled before it can be used again.

Because there are microorganisms in tap water, these substances are not good for the human body and are likely to cause a decrease in the body's resistance, so it is better to boil it and drink it.

Because tap water contains a lot of bacteria, it may also contain a lot of microorganisms, which will affect the health of the body.
