Survival Water Purification
Welcome back, survival enthusiasts! Today, I want to discuss a topic that is absolutely crucial when it comes to staying alive in a survival situation: water purification. In a survival scenario, clean drinking water can be very hard to come by. But fear not! With the right knowledge and some handy techniques, you can ensure that the water you consume is safe and free from harmful bacteria and contaminants.
One of the oldest and most reliable methods of water purification is boiling. Boiling water at a rolling boil for at least 1 minute (or 3 minutes at higher altitudes) kills most types of pathogens and makes the water safe to drink. This method is effective against bacteria, viruses, and parasites. However, it doesn’t remove chemical contaminants or heavy metals. Remember, always let the water cool down before consuming it.
Another popular method for purifying water in survival situations is using a water filter. A good quality water filter can remove not only sediment and physical impurities but also bacteria and protozoa. Look for a filter that has a pore size smaller than 0.2 microns to ensure the removal of harmful microorganisms. If possible, opt for filters that are also capable of removing chemical contaminants.
Chemical purification is a useful method when you don’t have access to fire or a filtration device. There are different types of chemical purifiers available, such as iodine tablets or liquid chlorine dioxide. These chemicals effectively kill most types of bacteria, viruses, and parasites. However, be aware that chemical purification methods may not be as effective against certain protozoa like Cryptosporidium. Always read and follow the instructions on the packaging carefully.
When you’re in a sunny location, solar disinfection (also known as SODIS) can be a practical water purification method. Simply fill a clear plastic bottle with water and leave it in direct sunlight for at least 6 hours (or 2 days if it’s cloudy). The ultraviolet radiation from the sun will kill most types of pathogens. However, this method does not remove physical impurities or chemical contaminants.
My 2 Cents
Remember, in a survival situation, it’s important to prioritize your water purification efforts. Boiling water is often the easiest and most effective method, but don’t hesitate to use other methods if boiling is not an option. It’s always a good idea to have multiple purification methods in your survival kit, as they can complement each other and provide backup options in case one method fails.
Stay prepared and stay hydrated, my friends!
