Discover 10 ways to purify water – Survival Tips


Access to clean water is essential for health, survival, and daily functioning. However, situations such as natural disasters, environmental pollution, or infrastructure failure can lead to a contaminated water supply. In such cases, knowing how to purify your water can be a lifesaver. This article explores ten practical methods to purify water, ensuring that it is safe to drink even when your usual water source is compromised.

Before diving into purification techniques, it’s crucial to understand what contaminants we may face. Water can be contaminated by pathogens (like bacteria and viruses), chemicals (such as pesticides or heavy metals), and physical debris. Each type of contamination requires a specific approach for effective purification.

10 Ways to Purify Water

  1. Boiling. Bring the water to a rolling boil for at least one minute to kill most pathogens. Boiling is one of the simplest and most effective methods to purify water. By bringing water to a rolling boil for at least one minute (or three minutes at higher altitudes), you can kill most pathogens. This method does not remove chemical contaminants but is excellent for microbial safety.
  2. Chlorine bleach. Add 8-10 drops of 6% or 8.25% bleach per gallon of water and let it sit for 30 minutes before drinking. Using household bleach or water purification tablets can effectively disinfect water. The key is to use the correct amount: typically, a few drops of bleach per gallon of water. Let the treated water stand for 30 minutes before drinking.
  3. Distillation involves boiling water and then collecting the condensed steam. This process removes both pathogens and chemicals, making it one of the most thorough purification methods available.
  4. UV light treatment is a modern method that requires a small device. This method uses ultraviolet light to kill bacteria, viruses, and other pathogens effectively.
  5. Portable water filters, such as filter straws or bottles, are convenient for on-the-go purification. These devices can filter out bacteria, protozoa, and sometimes chemicals, depending on the filter’s quality.
  6. SODIS (Solar Water Disinfection) utilizes sunlight to kill pathogens in water. Fill a clear plastic bottle with water and leave it in direct sunlight for 6 hours to effectively reduce the presence of harmful microorganisms.
  7. Cloth filtration can be used as a preliminary step to remove large particles. While this method won’t remove microorganisms or chemical contaminants, it’s useful for preparing water for finer purification.
  8. Building a DIY sand and charcoal filter can help remove physical debris, some chemicals, and some pathogens. Layer sand, charcoal, and gravel in a container, and pour water through it to purify.
  9. Iodine treatment, similar to chlorine, can effectively neutralize many pathogens. It’s important to note that iodine should not be used for prolonged periods or by persons with certain health conditions.
  10. Reverse osmosis systems offer a high level of purification, removing many types of contaminants, including some chemicals that other methods cannot. However, these systems require a significant investment and are more complex to use.

The importance of knowing these water purification techniques cannot be overstated. In emergency situations, these methods can prevent illness and even save lives. It’s important to understand and be prepared to implement these methods should the need arise.

What is the safest method to purify water?

The safest method to purify water often depends on the specific contaminants present. However, distillation is one of the most comprehensive methods, as it removes both biological contaminants like bacteria and viruses, and chemical impurities like heavy metals and salts.

How long should water be boiled to ensure it is safe to drink?

Water should be brought to a rolling boil for at least one minute. At altitudes above 6,500 feet, where water boils at a lower temperature, it should be boiled for three minutes.

Can household bleach be used to purify water?

Yes, household bleach can be used to purify water if it is unscented and contains 5-6% sodium hypochlorite. Use about 2 drops of bleach per quart of water. Let it stand for 30 minutes before drinking. This method is effective against most bacteria and viruses but does not remove chemical contaminants.

What are the disadvantages of using iodine for water purification?

While iodine is effective at killing many types of bacteria and viruses, it has several disadvantages. It can give the water an unpleasant taste, can be harmful to people with thyroid problems or allergies to iodine, and is not effective against all types of protozoa, like Cryptosporidium.

How effective is UV light in purifying water?

UV light purification is very effective at killing bacteria, viruses, and protozoa, providing the water is clear. If the water is turbid or colored, it should be filtered first to ensure the UV light can penetrate effectively.

Is a homemade sand and charcoal filter effective for purifying water?

A homemade sand and charcoal filter can be effective at removing sediments, some microbes, and improving taste and odor, but it will not remove all types of bacteria, viruses, or chemical pollutants. It’s often used as a first step before applying a more thorough purification method.
