Purifying water is a top priority to ensure your health, energy, and overall well-being. You should have the basic knowledge, techniques, and practices necessary to make water safe for drinking or other uses in an emergency or survival situations.
You may not have access to clean, safe water sources, and you might need to rely on the surrounding environment and your skills to purify water. Water purification is to eliminate harmful bacteria, parasites, viruses, and other contaminants that can cause illness or disease.
Water purification typically includes methods like boiling, filtration, chemical treatment, and utilizing natural resources.
Being knowledgeable about how to purify water can mean the difference between staying healthy vs encountering serious health issues in a survival setting. It’s essential to learn these skills, practice them, and be prepared to apply them when needed in a challenging and unpredictable situation.
Remember, in a survival situation, it’s crucial to use any means available to make water safe for consumption. Prioritize safety and do the best you can with the resources at hand. Additionally, try to procure and purify water from the clearest and least contaminated sources whenever possible.
Here are some specific water purification methods suited for survival scenarios:
Boiling is one of the most effective and simplest methods to purify water. Bring the water to a rolling boil for at least 1-3 minutes (longer at higher altitudes). Boiling will kill most bacteria, viruses, and parasites.
Use a portable water filter or purifier to remove bacteria, parasites, and other contaminants from the water. These devices typically have a pump or gravity system and use a fine mesh or other filtering technology to clean the water.
Use chemical treatments like water purification tablets or drops that contain chlorine dioxide or iodine. Follow the instructions provided with the specific product for dosage and wait time before consuming the water.
Improvised Charcoal and Sand Filter:
Layer a container with charcoal (from a campfire) and then sand. Pour water through this improvised filter to remove impurities. It won’t kill microbes but can improve water clarity.
Dig a hole in the ground and place a container in the center. Cover the hole with a plastic sheet, securing the edges with rocks or dirt. Place a small weight or stone in the center of the plastic to create a dip. The sun’s heat will cause condensation on the plastic, which will dip into the container.
DIY Water Purification Tablets:
If you have access to chlorine bleach or pool shock (calcium hypochlorite), you can create a makeshift disinfectant. Follow appropriate dilution ratios and guidelines for treating water.
DIY Ceramic Water Filter:
If you have clay or access to clay-rich soil, you can make a ceramic water filter. Mold the clay into a pot-like shape, fire it, and use it as a natural filter for your water.
Water Purification with Iodine (from a First Aid Kit):
If you have iodine tablets from a first aid kit, follow the instructions on the packaging for water purification.
UV Light Sterilization:
Use a portable UV water purifier to expose the water to UV-C light, which kills or inactivates bacteria, viruses, and protozoa. Follow the manufacturer’s instructions for effective use.
UV Water Purification (Using Sunlight):
Fill a clear plastic bottle with water and place it in direct sunlight for several hours to harness the sun’s UV rays to kill bacteria and other pathogens.
Purification through Pine Needle Tea:
Pine needles have vitamin C and can be used to make a simple tea. Although this won’t disinfect the water, it can help boost your immune system while you work on finding more reliable purification methods.
If you have a silver coin or small pieces of silverware, place them in a water container. Silver has antimicrobial properties that can help kill or inhibit the growth of bacteria and other microorganisms.
Solar Disinfection (SODIS):
Place clear plastic or glass bottles filled with water in direct sunlight for 6 hours or more. The sun’s UV rays will help kill bacteria and other pathogens. This method works best in clear and sunny conditions.
If you have a heat source, you can distill water by collecting condensation from boiling water and capturing it in a separate container. This process removes impurities and leaves behind contaminants.
Use natural materials like sand, charcoal, and gravel to create a makeshift filter. Layer these materials in a container and pour the water through the layers to remove larger particles and debris.
Use a clean cloth, bandana, or T-shirt to strain the water and remove larger particles and sediment. This won’t kill bacteria or viruses but can help remove visible impurities.
Clay Pot Filtration:
Make a clay pot filter by creating a pot from clay, firing it, and using it to filter water. The porous surface of the fired clay pot can help remove bacteria and other impurities.
Remember to choose the most appropriate method based on the available resources, the condition of the water source, and the equipment you have. Always prioritize safety and follow proper guidelines to ensure the water you consume is safe and clean.
