Boiling water can successfully kill or inactivate most types of bacteria, viruses and parasites but it does not remove chemical contaminants or impurities like heavy metals and minerals.
So let us examine the request more closely
Boiling water is a simple and effective method of purifying it, but it does have its limitations. While boiling water can successfully kill or inactivate most types of bacteria, viruses, and parasites, it does not remove chemical contaminants or impurities like heavy metals and minerals.
According to the World Health Organization (WHO), boiling water is one of the most effective ways to make water safe to drink. They advise bringing the water to a rolling boil for at least one minute to kill most types of disease-causing organisms. If you’re at high altitude (above 6,562 feet or 2,000 meters), you should boil the water for three minutes to ensure that all microorganisms are killed.
“Boiling water, however, only kills germs and bacteria but does not remove heavy metals and other impurities, so may not be enough to make water from all sources safe for drinking,” says Dr. Rishi Parashar, a General Practitioner at the Private GP Clinic in London.
It’s also worth noting that boiling water can only make it as safe as the original source. So if the water is heavily contaminated with toxins or chemicals, boiling alone may not make it safe to drink. In such cases, it’s best to filter the water first to remove any impurities before boiling it.
In summary, boiling water is a cheap and easy way to make it safer to drink, but it does have its limitations. While boiling can effectively kill bacteria and viruses in the water, it does not remove chemical contaminants or impurities like heavy metals and minerals. To ensure your water is safe, it’s best to filter it first before boiling, or to seek out bottled water if you’re in an area with questionable water quality.
Interesting facts:
- More than two-thirds of the global population rely on surface water sources like rivers, lakes, and ponds for their drinking water. (WHO)
- Drinking unclean water is one of the leading causes of illness and death worldwide. (CDC)
- Water purification methods have been around for thousands of years. The ancient Greeks and Egyptians are known to have used methods like boiling and filtration to make their water safer to drink. (History)
- Waterborne diseases like cholera, typhoid, and dysentery still claim hundreds of thousands of lives each year, mostly in developing countries. (WHO)
Table:
| Water Purification Method | Pros | Cons |
|---|---|---|
| Boiling | Kills most bacteria and viruses. Simple and inexpensive. No chemicals required. |
Does not remove chemical contaminants like heavy metals and minerals. May not be effective against all types of microorganisms. Requires access to a heat source. |
| Filtration | Removes most bacteria, viruses, and protozoa. Some types can remove chemical contaminants as well. Easy to use and portable. |
May not remove all bacteria and viruses. Not effective against dissolved solids or chemicals. Water can still be contaminated if the filter is not properly maintained. |
| Chemical Treatment | Can be effective against most types of microorganisms. Inexpensive and easy to use. |
May not be effective against all types of microorganisms. May leave a chemical taste or odor in the water. Can take several hours to work. |
| UV Treatment | Kills most bacteria, viruses, and parasites. No chemicals required. Easy and quick to use. |
Does not remove chemical contaminants or impurities. Requires access to a power source. May be less effective in cloudy or murky water. |

There are other opinions
Boiling water is the most efficient method of purification when a person does not have access to safe, treated water. Many organisms cannot survive when water reaches its boiling point of 212 F. In fact, if the temperature of the water is above 160 F, any organism in the water will not survive longer than 30 minutes.
Boiling water is most beneficial when the water carries some kind of biological contamination, such as harmful bacteria or microorganisms. These tiny creatures cannot survive in water that has been boiled for several minutes, making boiling a strong purification method in such cases.
Boiling is the easiest and most effective method for purifying water. But, how long to boil water before consumption? Some people say it only takes a minute while others say five minutes. You may have even read that you should boil water for 10 or 20 minutes to purify it.
Boiling is a great way to kill bacteria, viruses, and parasites from water. Fill a pot with water and heat it over medium-high heat, or over a fire. Bring the water to a boil and let it sit at a rolling boil for about 10 minutes. Let the water cool before drinking.
If you don’t have safe bottled water, you should boil your water to make it safe to drink. Boiling is the surest method to kill disease-causing germs, including viruses, bacteria, and parasites. You can improve the flat taste of boiled water by pouring it from one container to another and then allowing it to stand for a few hours, OR
More interesting questions on the issue
How effective is boiling water to purify it?
Answer will be: Boiling water is highly effective in purifying it, killing 99.9% of potential contaminants. To ensure safety, follow these guidelines: Boil water for at least one minute (as recommended by the CDC) Add an extra minute or two for added security.
How long does water stay pure after boiling?
You can store boiled water in well-sealed containers for 6 months. Write the fill date on the containers so you know when to refill them.
What does boiling water not kill?
The instructions below show you how to boil and disinfect water to kill most disease-causing microorganisms that may be present in the water. However, boiling or disinfection will not destroy other contaminants, such as heavy metals, salts, and most other chemicals.

Is it safe to drink tap water after boiling?
As an answer to this: Boiling the water kills microorganisms such as bacteria, viruses, or protozoans that can cause disease. Boiling makes the tap water microbiologically safe.
Does boiling the water make it safe to drink?
The response is: We will answer all your queries about boiling water in this article. In a nutshell, boiled water is generally safe to drink, as all germs and bacteria are killed during the boiling process. However, chemicals and minerals may still present.
Does boiling water water make it pure drinking water?
The reply will be: Boiling water is the simplest and most effective way to purify it and make it safe to drink. The boiling process kills bacteria, viruses, and other organisms that can cause illness. If you don’t boil your water, you could be at risk of developing a water-borne illness.
Do I have to boil water to purify it?
It must be followed by boiling or disinfection to purify water for drinking. Most water filters are made of a screen with many tiny holes in it. These filters can remove protozoa and some bacteria, but they cannot filter out viruses because viruses are too small.
How does pure water increase the boiling point?
Pure water has a fixed boiling point at standard atmospheric pressure; however, if some impurities are added in the water, e.g. common table salt (sodium chloride), the boiling point of the water changes; if 100 grams of salt is added to 1 kilogram of water, the boiling point of the impure water would increase by 1 degree Celsius.
