8 Ways To Purify Water For Drinking In Emergency Situations
There’s a lot to worry about if you ever find yourself in a true survival situation, but a primary concern should be your water supply. Whether you’re lost in the wilderness or living through a natural disaster that caused the grid to go down, your situation will quickly deteriorate if you don’t deal with your hydration concerns with a water purification strategy.
While the world is full of fresh water that’s safe for drinking, you’ll run into trouble if you can’t source it or purify it when you most need it. The human body can go for a month or more without food, but your system will start to shut down after a few days without water. Thankfully, there are dozens of water purification strategies to know in survival situations that could save your life if you know how to put them into action.
8 Ways To Purify Water in an Emergency Situation
Once you’ve secured a water supply, your primary objective should be to treat it. Purifying water frees it of microbial contaminants and disease, which makes it safer for your digestive system to handle. There is no limit to the ways you can clean up your water supply, but eight smart strategies for treating water in emergency situations are below.
1. Use a Filter
Perhaps the easiest way to deal with dirty water is to filter out the impurities immediately after you collect it. Some of the filter options available include the following.
– Pump-action filters use a pump system to force untreated water through a filter cartridge. This draws pathogens and other contaminants out, so you get instant fresh water. It’s good to look for one with a silver-embedded ceramic cartridge like the Katadyn Pocket filter so that the silver disables dangerous viruses as well.
– Gravity water filters rely on the power of gravity to push water through a reservoir to a hose with hollow membranes that filter out contaminants so it’s safe to drink. They tend to be more durable than other filters with moving parts, but the filtration process itself can be slow. Systems like the Platypus GravityWorks make the process easy by providing separate reservoirs for dirty and purified water.
– A new option for convenient water filtration is a survival straw like LifeStraw. This is a tool that filters water straight from an impure source just as fast as you can drink it. Designed to remove as much as 99.9% of dangerous microbes, these straws can provide you with up to 1,000 liters of fresh water before you need to replace it. For an ultra-convenient option, consider a water bottle with a built-in filter. This allows you to fill it with untreated water and sip out clean immediately.
2. Kill Pathogens with UV Light
UV light is a powerful way to kill microorganisms, making it an effective way to eliminate waterborne pathogens from your drinking supply. For the best portable option, it’s smart to look into using a water bottle with a built-in UV light filter from Mountop. If you want to treat water in a separate container, consider the SteriPen, a screwdriver-sized device designed to use UV light to kill off all contaminants in up to 15,000 liters before needing to be replaced.
