Below, I am going over the different methods for making water gathered in the wilderness safe for consumption in detail...
Before we remove bad things like bacteria, protozoa, etc. from the water, we need to gather a somewhat clean sample - that is make sure no mud, sticks, etc. 'floaties' are in the water. While some methods will remove these macro contaminants, they will inevitably lessen your filter life. Therefore, I always carry the Helikon-Tex Survival Water Filter Bag with me: I gather the dirty water in this bag and let gravity 'filter' out macro-contaminants before I further treat it for the micro-contaminants.
The first and oldest method - boiling - requires no specialized tools, just a fireproof pot and a fire. Boiling is the least expensive, but also slowest method of making water safe for consumption. Indeed, after boiling the water for so many minutes (depending on elevation, cf. below...), it needs to cool off again before it casn be consumed - a process that can be irritating, especially during the summer months.
Water filtration is the next-simplest method of making water safe for consumbtion. It works especially well for water gathered in fast-flowing environments, like e.g. from a mountain stream, or a fast-flowing river. My tools of choice for this task are,
- MSR Miniworks EX: A quick and easy way to pump filtered water into a Nalgene bottle. Its disadvantage is the bulk and weight - I usually don't carry this when backpacking, but do have it along when car-camping or overlanding.
- Platypus GravityWorks: It doesn't get much simpler than this. Just gather water in the "DIRTY" water bag, hang it from a tree and let gravity do the work; clean drinhable water will gather in the "CLEAN" water bag (or a Nalgene bottle,) and be ready for consumption.
Next in the list of treatment options is water purification. This is my goto method about 95% of the time. I do not have to worry about the flow of the water source where I gather my water, and I can be certain the water will be safe for consumption. My preferred tools for this are:
- GRAYL GeoPress 24oz Water Purifier Bottle: This is by far my preferred water safety tool. It is a bit on the heavy side, but that is a small 'price' to pay IMO for the peace of mind that comes from using this bottle. Typically, I'll carry one Nalgene bottle with drinking water, and this GRAYL empty. I then keep refilling my Nalgene bottle with purified water from the GRAYL, and carry a full bottle of purified water in the GRAYL itself, giving me direct easy access to 56fl.oz/1.6l of water.
- GRAYL UltraPress 16.9oz Water Purifier Bottle: Like the GeoPress above, just slightly smaller capacity, and therefore slightly lighter. The UltraPress is now also available in a Titanium version.
Finally, disinfection to make water safe for consumption. Some folks swear by this. I, on the other hand, do not care much for it at all. That said, I do have disinvectant tablets in my emergency kit; but that is - for me - really the only time I would gravitate towards using tablets... As far as the SteriPen is concerned, I have used one in the past, but I do not like relying on electronic devices for life-saving applications:
- Aquatabs: These are the tablets I carry in my emergency kit. They are cheap and effective, but they do make the water taste of chemicals... Like I mentioned above, that is OK in an emergency situation, but not when I'm enjoying the great outdoors for fun.
- SterPen Ultra UV: UV light is a powerful disinfectant. However, electronics can break, run out of battery, etc. Therefore it's not something I currently carry along.

Boiling
Boiling eliminates bacteria, viruses, and protozoa; it does not remove floating debris, heavy metals, or chemicals.
Boiling water is one of the oldest and most effective methods of water purification, dating back centuries as a way to make water safe for drinking by killing harmful microorganisms and pathogens. This simple yet powerful technique involves heating water to its boiling point, typically 100 degrees Celsius (212 degrees Fahrenheit), to destroy bacteria, viruses, and parasites that may be present in the water. At elevations up to 6,500 feet (~2,000 meters,) boil the water for a minute - that is bring the water to a rolling boil, then let it go at that for 1 minute...) For elevations above 6,500ft/2000m, increase the boil time to 3 minutes.
When water is heated to its boiling point, the high temperature causes the microorganisms and pathogens in the water to be killed or inactivated. Bacteria, such as E. coli and Salmonella, viruses like Hepatitis A and Norovirus, and parasites such as Giardia and Cryptosporidium, cannot survive exposure to the intense heat of boiling water. As a result, boiling effectively sterilizes the water, making it safe for consumption.
The process of boiling water works by disrupting the structure of the microorganisms' cells, denaturing their proteins, and ultimately causing their death. The heat energy from the boiling water destroys the cell membranes and enzymes of the pathogens, rendering them unable to function and reproduce. As the water continues to boil, any remaining microorganisms are eradicated, ensuring that the water is free from harmful contaminants.
In addition to killing microorganisms, boiling water also helps remove certain chemical contaminants and impurities. Volatile organic compounds (VOCs), chlorine, and some heavy metals may evaporate or precipitate out of the water during the boiling process. However, it is important to note that boiling water is not effective in removing all chemical contaminants, such as pesticides or industrial pollutants, which may remain in the water even after boiling.
One of the key advantages of using boiling water as a purification method is its simplicity and accessibility. Boiling water requires no special equipment or chemicals, making it a practical and cost-effective way to ensure the safety of drinking water, especially in emergency situations or when other water treatment methods are not available. Boiling water is a time-tested method that has been used by cultures around the world for centuries to prevent waterborne diseases and promote public health.
Boiling water is a reliable and effective method of water purification that works by killing harmful microorganisms and pathogens through the application of high heat. By understanding the science behind boiling water and the contaminants it cleans out, individuals can make informed decisions about water treatment and ensure that they have access to safe and potable drinking water. Whether in the wilderness, during a natural disaster, or in everyday life, boiling water remains a valuable tool for safeguarding health and well-being by providing a simple yet powerful way to purify water.
