    Boil your water, then after it cools run it through a charcoal and/or osmosis filter. Even then, it’s still not great. Commercial/community water treatment isn’t some silly little optional process.

      Get a water filter that’s designed for camping. The two varieties I’ve seen are either a hand pump or using gravity to force the water through a ceramic filter. Try to pick water that is relatively clean looking (not obviously murky, and it helps to pick flowing water).

      Best tasting water I’ve ever had and you won’t get giardia (the most common cause of diarrhea symptoms described above).

      • I tried a hand pump while camping and never used it again. The tannins in the water (decayed plant matter secretion) isn’t captured by the filter and hit me pretty hard.

      The biggest risk out in the woods is microorganisms. If you boil it or use a well designed filter you are likely going to be fine if you’re drinking otherwise clear water.

      I wouldn’t just filter the water from the Hudson river and go to town, but if it’s 10 miles to the nearest road I think you’re probably doing better than your tap

            And a massive amount of fuel.

            Have you ever tried to evaporate a liter of water? It takes a lot of energy to do so. Fun for a science project, but if you need enough to stay alive/be comfortable, it’s a lot easier to bring water.

              If you’re in the woods, you have access to a virtually unlimited amount of fuel. If you’re in a desert, the fuel source is nuclear. This is a technique taught in survival courses/manuals and military field guides all over the world.

                Sure, but gathering wood takes a lot of effort and energy. It’s an option if you don’t have the filters, but the original question was why not distill if boiling and filtering ends up in “not great”.

                If I have to survive, and I can do with boiling and filtering, I’ll take “not great” water over spending hours gathering and chopping wood to keep a fire going long enough to vaporize a liter of water.

          distilled water is fine the issue is if you drink mostly or only distilled water, it doesn’t have the minerals you’ll find in tap water and long-term missing those isn’t healthy. even so you can get those minerals from other sources like food or supplements most of the time.

          • Unless you’re starving to death, you absolutely get those from food. The amount of minerals in even hard water is miniscule compared to what’s in food. Drinking distilled or RO water, even regularly is not going to hurt you.

            Drinking giardia on the other hand…

        Yes

        At least bacteria. Viruses are a whole different beast but usually viruses are also not the problem in natural watersources.

        Be free comes to mind, very popular in europe. Sawyer filters are very popular in the US

        There are also combo filters that filter sediment and bacteria and pass the water through a charcoal filter to remove taste and organics.

          From Lifestraw website:

          The majority of LifeStraw products for individual use are microfilters with an absolute pore size of 0.2 microns which remove bacteria, parasites, microplastics, and dirt/silt.

          LifeStraw also manufactures ultrafilters/purifiers that, in addition to the above contaminants, also remove viruses. The absolute pore size on these purifiers is 0.02 micron.

          Sawyer filter inline with a camelback is awesome. I’d just fill up my camelback in a stream using a (clean) handkerchief to get the large debris out and then let the filter do the rest.

        The most common cause of symptoms like in OP’s story are multicellular organisms. While still microscopic, they are plenty large enough to get caught in a filter. The filters are usually good enough to catch bacteria too.

      I always wondered: does these filters degrade?

      If they filtering stuff that small, do they clog? Do you need to rinse them? Run water in opposite direction to remove what they blocked before?

        They clog and you do need to rinse them, and running (clean) water in the opposite direction is a common way to clean them.

        They do eventually degrade or clog to the point of being unable to function and then you have to replace them. Usually they fail such that it gets slower to filter the water rather than letting dirty water through, although that’s not always the case. One time I had a cracked filter, and the symptom was the filtering went suspiciously quickly. I think I drank some only partially filtered water before I figured it out (didn’t get sick though).

  • Welcome to giardia or whatever other parasites and bacteria are in natural water sources.

    Pretty much all natural surface water, no matter the source, is gonna have stuff in it that can make you sick. Maybe some cramps and diarrhea, some potentially lethal. Any time you drink untreated water it’s a risk no matter the “bro science” about how some is “safe”. Even glacial water has bacteria in it. Just some sources the concentration of bad stuff is going to be low enough that your body can hopefully deal with it without you becoming symptomatic.

    Use proper filters and treatments designed for biologically contaminated water, or filter and boil your water before consuming. Stay safe out there!

      How come animals are fine drinking it? And what about pre industrial people? Was everyone just always sick?

      • Plenty of animals are riddled with parasites, and early humans absolutely got sick. Think of all the cholera epidemics even in recent history. I’m sure some animals get sick but I’d bet their stomachs are a far harsher environment for bacteria and parasites to survive so it’s less likely for them to be ill.

    I feel like boiling PLUS the Brita would be a pretty solid combo. Boil to kill everything then Brita to remove the remaining inert sediment. I can’t think of any metals or anything that there would be enough of in river water to hurt you after you’ve killed anything that was alive.

      Yes, this is what I was told in a survival course (as a company team building). You have to filter out large particles, even a few layers of cloths is enough. Then you boil it to get rid of bacteria or other problematic stuff.

          My mostly on my gut feeling based counter argument would be:

          • So what? You are cooking the water afterwards cross-contamination between water samples isn’t a huge deal. Additionally, Filters (especially things like cloth) are cleanable and potentially sterilisable via cooking.

          • cooking is a violent process, grinding down particles, lessening the effectiveness of the filter. So you are potentially worse off, for no real gain.

          • You can’t always cook. Sometimes you have to sterilise water another way. E.g. via exposure to as much UV/Sunlight as possible. Particles in the water lessen the effect or prevent this from happening

      Boiling isn’t necessary. They make antimicrobial tablets you can add as well. We used them when I was on a 2 week backpacking trip and basically just used a bandana folded over 4 times for sediment, fill at the top of the water with the neck facing downstream, and then add a disinfectant tab and let it sit for however long it says. It tasted a bit like pool water if you drank it immediately, but if you filled all your bottles at once, they usually didn’t taste very chlorinated and it was pretty amazing water.

        I mean, everything that kills the bad stuff works. If you had a strong portable radioactivity source, that would probably work just fine, too. Sadly, the people at the airport don’t like it when I bring my enriched uranium to the camping vacation.

        Jokes aside, I would say that chlorine tabs are nice for an emergency, but for a planned trip I’d assume I’d have access to heat anyway. Or, just bring a filter.

          When we’re hiking 15 miles per day and were drinking 4 gallons of water per person in the New Mexico heat, stopping to set up a fire and boil ~40 gallons of water in the middle of the hike wasn’t really an option. I also appreciated not having to carry 32lbs of water on me all day long.

            Fair point. My last camping trip was in mid-temperature weather, and rather relaxed, so I basically lived off instant coffee and tea. Plus, the water was really clean, so in some cases I just risked filling my bottle from like the middle of a lake without treatment. But a filter is definitely on my to-buy list.

    I had a similar experience at a pseudo pagan ritual/drum thing/moonlit naked dance thing. They’d stocked the sweat lodge with several bottles of water. Some for drinking and others full of river water for tossing on the stones. I failed to correctly identify them in the dark and was very sick as a result.

    The Brita would (should) pull out various carcinogens from the water since they will stick to the filter rather than the water. But it won’t do anything for bacteria, viruses, amoeba or any other protists. Which would make you acutely sick.
