Water Purification. Why Boil Water? If you are planning on using a freshwater source that has not been purified — boiling the freshwater should remove any chance of getting sick from bacteria.

Once ingested, nitrates are converted to nitrites. This can cause severe illnesses and even result in death if left untreated. Lead is also toxic. It has been shown to inhibit physical and mental development in infants and young children.
It also causes chronic illnesses such as diabetes, kidney failure, and high blood pressure in adults when ingested in large quantities over prolonged periods. Lead is by far the most common chemical in drinking water. It mostly comes from the lead pipes used to channel tap water into homes. An excellent example of a problem of lead in water is exhibited in the Flint water crisis in Michigan.
Residents of Flint have been facing a water crisis since , and they have to use boiled water for all their domestic needs, including bathing. As mentioned, some water is lost through evaporation during boiling. Considering that chemicals do not evaporate during boiling, their quantity remains at the same levels while the amount of water decreases. The result is an increase in the overall concentration of these chemicals.
As such, boiling the water only makes the situation worse in such instances. At the same time, boiling water does not kill minerals or even remove them. Heat can also be a catalyst for some chemicals. It can lead to a transformation that can make the chemicals more toxic.
Water boils at degrees Celsius, which is enough to transform mildly harmful chemicals into overtly toxic ones. Unfortunately, it is impossible to tell which types of chemicals are present in contaminated water without a test. People in remote areas are at a disadvantage in this case as they do not have access to testing services and facilities.
The effectiveness of boiling water for purification is not always guaranteed. Fortunately, there are other methods that are much more effective against chemicals and micro-organisms capable of withstanding extreme temperatures:. Distillation is way better and effective than boiling water since it removes more impurities, while the latter is ineffective against most chemical contaminants in drinking water. However, taking it one step further can help rid your drinking water on a wide range of these chemicals, including lead, mercury, arsenic, and nitrates.
Distillation may sound complicated, especially for outdoor enthusiasts looking to boil and distill water on the go.
However, you do not need any fancy equipment to distill water. All you need is a source of fire and two containers: a boiling pot and a smaller container such as a glass container or water bottle. Filtration is one of the more effective methods of water purification than boiling if it combines both the physical and chemical methods of filtering. While it is not the best, it has better results compared to boiling.
It is for this reason that filtration is used on a large scale by industries and public service providers. Your tap water undergoes filtration before being channeled to your taps. Filtration does not get rid of all of the minerals and salts present in the water.
As such, this method is considered healthier compared to other purification methods. Learn more about filtration on our guide to water purification and discover the pros and cons of this method.
Chlorine is a popular water purification chemical that has been in use for decades. It is often used to treat ground and tap water. In most cases, the water that flows from your taps contains mild traces of chlorine. It is effective for killing all types of organic contaminants.
It is important to note that chlorine may have adverse health effects on people suffering from certain conditions, such as thyroid complications. As such, it is important to dechlorinate water as a further purification method. Therefore, boiling water is better than chlorination due to its effectiveness in killing organic impurities and also the health implications of chlorine.
Water is life. Therefore, it is important to purify water because it can also induce health complications if it is contaminated. Considering that there has been a rise in cases of runaway water pollution, it is prudent to take extra precautionary measures to ensure that your drinking water is clean. Boiling is one of the simplest and most effective water purification methods. The effectiveness of boiling water for purification has been tested and proven time after time.
