Can you drink the water in a pressurized well, it looks clear? 5

The water in the pressurized well is not drinkable directly, although it looks clear, but it has not been professionally filtered and disinfected, so drinking is easy to cause gastrointestinal discomfort, and it does not meet the requirements of hygienic diet, so we must pay more attention to it, drink the specified standard, and strictly disinfect the tap water will be better.

Hello, the pressurized water well is pumping shallow groundwater, whether it can meet the drinking standard can not be seen by eyes, because groundwater in many places in China is polluted, especially near towns and factories, groundwater contains a lot of heavy metals dissolved in it, it is not visible. If you want to drink it, it is best to send it for testing first, especially the heavy metals in it, which are the main indicators of detection.

Of course, you can drink it, and the water in the well is much cleaner than the tap water. As the saying goes, if you don't do it, you can't eat it.

No. Because the pressurized water well is very shallow, if the pressurized water well is too close to the sewer or stinky ditch, the quality of the water will not be too good, and the water of the pressurized water well is generally alkaline, that is, the water quality is too hard, and it also contains some harmful elements, so it is best not to drink.

Whether you can drink it or not, you have to take a water sample for testing, and compare it according to GB5749. In general, this water cannot be drunk. It looks clear, but who knows what's inside. For example, the sea water is also very clear, and that thing really can't be drunk.

The water in the pressurized well has not been professionally disinfected, and it is generally not recommended to drink it directly, because it does not meet the scientific and hygienic dietary requirements and habits, so we must pay attention to drinking ingredients that meet the safety and health standards to be more conducive to health.

Pressurized water wells are groundwater, of course, under normal circumstances, are very hygienic and meet drinking standards, but some groundwater can not be drunk normally because of pollution, and laboratory tests are needed to determine whether it meets drinking standards.

The water in the pressurized water well, as long as it is clean, can be drunk, it turns out that most of our rural areas are pressurized wells, all drink the water in it, and now this situation is relatively rare

The water in the pressurized well is drinkable.

Now the water pollution of groundwater is also very serious, it is best to use a water purifier to filter it before drinking, if the water purifier is reverse osmosis, then it can be drunk directly. ”

If the water in this well has not been used, is it suitable for people to drink? Just looking clear to conclude that it may not be appropriate. It's best to let the water company do the test to find out!

It is best not to drink the water in the pressurized water well, because the pressurized water well is very shallow, if the pressurized water well is too close to the sewer or stinky ditch, the quality of the water will not be too good.

Hello, the reason is that the air is discharged with water, so that a negative pressure is formed between the valve and the water, and the water is lifted up under the action of atmospheric pressure. The working principle of the pressurized water well: there is a piston above the pressurized water well, and there is a valve below, the piston and the valve are a one-way valve, so that the air goes up and not down, when the piston goes up, the valve opens, and the air in the pipe below can be pumped to the upper cavity, when the piston goes down, the valve is closed, and the air comes out from the piston side to disturb the suspicion, so that the circulation will pump the pipe below into a vacuum, and the water will be pumped up under the action of atmospheric pressure.

If the seal is not good, the air outside will leak into when the piston goes up, and when the piston goes down, the air in the cavity can also leak from the valve into the pipe below, so that it is difficult to evacuate the pipe.

Generally speaking, if the deep-water well is far away from the mining area, there is no heavy smelting work nearby, and there is no chemical industry, there is no problem if the water is boiled. It's just that the metal ion content may be higher, and after boiling, most of these ions will be separated from the water. The discoloration of the tea is due to the reaction between the tanning and the metal ions.

After boiling, there is no such phenomenon, which means that there are not too many metal ions, so it doesn't matter.

In your case, I analyzed that the water contains divalent iron ions, which turn pale black with tea, which is the iron specialty ion and the tannin genus in tea.

The acid reacts to produce ferrous tannin, which is a faint black color, but it is actually black-green.

When water is boiled, during the heating process, the ferric ions are oxidized by the air to form ferric iron, ferric oxide. This iron oxide is insoluble in water and does not react with the tannic acid in tea, so it does not look like an abnormal color. Actually, it may still be a little yellowish, this is the tea you brewed, and that little bit of pale yellow is masked, and you can't see it.

Given this situation, my suggestion is not much of a problem. After all, this iron ion content is very low, and if it is high, the tea will become very dark when poured. And the color of the water will also be very yellow after boiling. So, but it doesn't hurt to eat!

Well water is rainwater that seeps into the ground, passes through the natural filtration of soil, sand and gravel, and finally reaches your well. The benefits of well water are, firstly, that it is free, and secondly, it is pure natural water if there is no source of pollution nearby. The disadvantages are, first, that it has not been disinfected, second, there may be illegal pollutant discharge from nearby factories into the ground, and third, natural rainfall may also carry polluting stove litter.

So well water can contain chemical contaminants and bacteria that are not good for your health. Officially, groundwater that has not been disinfected or tested cannot be used as drinking water. Tap water is generally river water, but also groundwater, or a mixture of the two.

But all tap water is sterilized and filtered. After boiling or filtering from household water dispensers, it can meet the drinking standard.

You can drink it.

Boiling water can kill bacteria and remove substances harmful to the human body, because tap water is chlorinated, and chlorine interacts with residual organic matter in the water to form toxic carcinogenic compounds such as halogenated hydrocarbons and chloroform. When the water temperature reaches 90, the content of halogenated hydrocarbons rises to 191 micrograms, and chloroform rises to 177 micrograms, both exceeding the national standard by 2 times. When the water temperature reached 100, the levels of halogenated hydrocarbons and chloroform were 110 micrograms and 99 micrograms per liter, respectively. If you continue to boil for 3 minutes, the two substances quickly drop to micrograms and micrograms per liter, respectively, to meet the drinking standard. Therefore, it is best to boil water for about 3 minutes.

After boiling water, there is a layer of solidified calcium-magnesium compound underneath.
