Water is essential for life, and in an emergency situation, having access to clean, potable water is crucial for survival. Contaminated water can lead to illness and dehydration, making it vital for preppers to be familiar with various water purification methods.
Here are the top five water purification methods every prepper needs to master to ensure a safe and reliable water supply during a crisis.
- Boiling
Boiling is one of the simplest and most effective ways to purify water. It kills bacteria, viruses, and parasites that can cause illness. To purify water using this method, follow these steps:
a. Collect water from a clean source and strain it through a cloth or coffee filter to remove any debris. b. Bring the water to a rolling boil and maintain it for at least one minute (three minutes at high altitudes). c. Let the water cool before consuming or storing it in clean, airtight containers.
Boiling is an ideal method when you have access to a heat source, such as a stove or a campfire. However, it does not remove chemical contaminants or improve the taste of the water.
- Chemical Treatment
Chemical treatment is an effective method for killing microorganisms in water. The two most common chemical treatments are chlorine and iodine.
Chlorine: Liquid household bleach can be used to purify water. Add 2-4 drops of unscented bleach per quart of water, stir well, and let it sit for 30 minutes. The water should have a slight chlorine odor; if not, repeat the process and wait another 30 minutes.
Iodine: Iodine tablets or tincture can also be used to treat water. Follow the manufacturer’s instructions for the correct dosage and wait time. Keep in mind that iodine has a strong taste and is not recommended for pregnant women or those with thyroid issues.
Chemical treatments are lightweight and portable, making them a popular choice for preppers. However, they may not be effective against all types of contaminants and can leave an unpleasant taste in the water.
- Water Filters
Water filters are designed to remove bacteria, protozoa, and some viruses from water. They use physical barriers, such as ceramic, carbon, or hollow fiber membranes, to trap contaminants. Some filters also incorporate chemical treatments for added protection.
There are various types of water filters available, including portable straw filters, pump filters, and gravity-fed systems. When selecting a water filter, consider factors such as weight, ease of use, and the filter’s pore size (measured in microns). A smaller pore size provides better protection against microorganisms.
- Ultraviolet (UV) Purification
UV purification uses ultraviolet light to destroy bacteria, viruses, and protozoa in water. This method is effective and does not alter the taste of the water. Portable UV purifiers, such as pen-like devices or small battery-operated units, are available for preppers.
To use a UV purifier, follow the manufacturer’s instructions for the required exposure time and ensure the water is relatively clear, as turbidity can reduce the effectiveness of the UV light. Keep in mind that UV purification requires a power source, such as batteries or solar power, which may be a limitation in some situations.
- Solar Disinfection (SODIS)
Solar disinfection is a low-cost method that uses sunlight to purify water. It is effective against bacteria, viruses, and protozoa but requires specific conditions to work efficiently.
To use the SODIS method:
a. Fill clear plastic bottles with water and place them on a reflective surface, such as aluminum foil or a metal sheet, in direct sunlight.
b. Expose the bottles to sunlight for at least six hours on a sunny day, or two consecutive days if it’s cloudy. c. Once the exposure time is complete, the water is safe to drink or store in clean, airtight containers.
SODIS is an accessible and eco-friendly method, but it may not be suitable for all situations due to weather conditions and the time it takes to purify the water.
Mastering these five water purification methods can significantly increase your chances of survival during a crisis by ensuring a reliable supply of clean, potable water.
Familiarize yourself with each method’s advantages and limitations, and consider incorporating multiple methods into your preparedness plan for added versatility and security.
Ultimately, having a diverse range of water purification skills at your disposal can make all the difference when facing a challenging situation where clean water is scarce.
