This should be taught in schools. How to dig a seep well, distill water, and make a filter in a situation like this. 90% of our survival situations come out of recreational activities, and 90% of those are done around water. No reason to ever dehydrate if you know how to obtain clean water. GREAT VIDEO.
And always remember if you have no other choice then to drink untreated water it is VASTLY better to drink from moving water rather then stagnant water. Given a little time and oxygen aerobic bacteria always out compete the more dangerous anaerobic bacteria.
@@RealitySurvivalI never filter fresh water and prefer to drink directly from lakes, rivers and streams. A healthy human body is the best natural filter system.
@coolguyhentaisenpai "Yeah?" ..Yes "how does that work in a puddle?" ..it doesn't "what if the stream is barely a dribble?" ..doesn't apply "come on it's not a hint" ..hint aka tip or trick "it's advice that's hardly helpful" ..it's helpful you have been criticised frequently in life haven't you.. Be kind to yourself and others.
Boiling its still the best option, its cheap and 100% guaranteed to give you clean water every time. Just boil it on time while you are still not thirsty so that you dont have to drink it hot.
@@AfterShockzPb There are also set ups you can make that let the water sit in sunlight (UV rays and heat both help kill bacteria and viruses while evaporating the water to help collect it) in a container and evaporate and collect onto a “lid” and drip into a clean container, so you have clean water.
Bonjour . Je suis Québécoise et parle Français. Je vais écrire en Anglais mais excusez mes fautes. I do speak French so excuse my English fault. This vidéo is so instructive and interresting that I did share it with my friends from different countries. Also I told them to read the comments because there are a lot to learn. I am a retired nurse. And my best friend had a kdnney surgery for Bosniak cell 4 . So I consider very much important for Her To know what is explain and reconize the déshydratation sarde. THANK YOU SO MUCH To you and also To the people who did instructive comments. This is a gift of GOD.
A friend of mine picked it up and admonished me to 'always' filter my water. He said he spent several days in his tent. I don't remember him telling me how he got over it, or how he got out of the back country in such a state. We used to canoe camp and backpack together. He surprised me. I have a Katadyn Pocket ceramic filter.
To those who are wondering how people survived before filtration and boiling was used: Most diseases that we get today come from doing things in close quarters: farming, living, defecating, etc. In the middle ages, pedestrians wore wide rimed hats in European cities to avoid getting hit by the poop that people threw out of their windows. Domesticated animals gave us many diseases as well, because we kept and still keep them unhealthy, close together, and sometimes the floor of their living spaces is made of their own feces. So back to my point, we didn't get sick because most of these pathogens didn't exist yet, and most of these water sources were not contaminated yet. The earth was also much more temperate. Most of Africa and the Middle East was not desert before the 7th century. There were plants, streams, and ecosystems. Streams are natural water filters, they don't kill all bacteria and parasites, but the water flow keeps solids (metals, fungi, plants, etc) from accumulating. The source of the water upstream also matters, springs and fresh rainwater are much safer. People knew where to get their water back then too, because if somebody died from one water source, everybody else knew to avoid it from then on, and they saw the patterns of what safe water sources were like. Although civilized humans have become cushioned, it isn't weak to take steps to avoid getting sick, just because our ancestors didn't have to do that.
Great video JJ Dr. Anja knows her stuff, and I hope to hear more. I also see you are tightening your transitions in the video with your edits. And a GOD shot ending lol. I miss you dude, but I am glad you have real quality guest speakers. Good luck in your life and education. Stay safe and hit dem books. :)
I like the idea of that UV thingy that purifies (or does it sterilize? Obviously, it doesn't actually filter the water) your water. Most all of us here have the means to boil our water and some of us have the means to filter our water (always a good thing!). For that UV pen I could see that being equipped with extra rechargeable batteries and a means of recharging them (i.e. a small solar cell charger like the ones they sell through Harbor Freight) would be a great way to go for powering that unit.
Excellent video with great practical advice - memorization aids such as the rule of "3" are very useful in a survival situation. Thank you for all the warnings about the water, I have been stuck drinking "running" water a few times in emergencies and became kind of "cavalier" about it - thank you for the cautions and personal experience. Ciao, L
I just now stumbled upon this and found it to be very informative. I am currently residing in Ireland, and when out and about I would come across lots of the things talked about in the video. (Thumbs up for the editing and producing of the video.)
Use a bandana over your water bottle as a pre-filter to stop the larger particles from getting in it as you fill it. Today ( 2016 , two years later ) there are several water bottles that you take the top off and remove the attached filtration system , then fill your bottle . put the filter in it and attach the top then drink. The part that touches your mouth never gets near the unfiltered water so it does not become contaminated from the untreated water. Three good ones that comes to mind are the Grayl and the Sawyer along with the Life Straw water filtration bottles. Cooking water gets boiled since you wanted a hot meal and there is no reason to filter it.
Great video, it's good to hear someone who actually knows a thing or two about making water safe to drink. BTW there is a way to boil water on the go by using a quality MRE heater - fill it with water, seal it and stick it in your backpack, once activated they reach a rolling boil quite fast without the use of a flame, though waiting for your water to cool enough to drink is another matter.
The one item almost never addressed concerning water purification is the presence of toxins (these come in many forms an example being nitrates). While in many areas the probability of their presence is low, it is not zero. The problem is that they are difficult to detect and in many cases difficult to remove. Depending on the toxin their effect may be felt immediately or may be delayed for a long period depending on frequency of ingestion and amount ingested. Their effect can be mild to life threatening. Understanding the environment you are in and land use practices such as farming, mining, manufacturing and military use will give some indication about the possible presence of toxins.
For the above reason most water purifiers and filter manufacturers suggest in fact warn users that their products should not be used in salt water [sea water] or chemically contaminated water such as from mine tailing ponds or agricultural collection ponds. It's good advice Donald that you stated this.
@@LAPGOCHINSTRUCTOR I really enjoyed exploring the American parks, you learn quite quickly returning to the UK that there is a big difference between suspensions and solutions. Many places around me have arsenic contamination from old mine workings which would need a reverse osmosis filter to remove it (or a still)
Good video straight to the point and very informative. She being a doctor, working the search and rescue team and knowing the outdoors and teaching first aid lends confidence in her info. Thanks
No doubt others have mentioned this but, yes, water "boils" more readily at lower elevations than higher. That is, at 212F, sea level water will boil, but water at a height of say two miles, may not boil. It will still be the same temperature as the sea level water. The trick is if you are are looking for boiling activity as a sign of reaching the right temperature, you may have to re-calibrate.
Actually you have it backwards. Water boils at lower temps at higher elevations. But the reason looking for a hard boil works at all altitudes is because the water becomes pasteurized at temps that are below the boiling point at all reasonabke altitudes. www.google.com/url?sa=t&source=web&rct=j&url=www.fsis.usda.gov/shared/PDF/High_Altitude_Cooking_and_Food_Safety.pdf&ved=2ahUKEwjfit2gpfTcAhXRuFMKHZ6gCIUQFjACegQIZRAF&usg=AOvVaw1toSAelVdu-tpMjGiA6vhI
Great info JJ. At first I was thinking "wow, he had a really professional looking guest video," but then I realized you produced it. Great job man! You're taking your filming up a definite notch!
Growing up my father took me every weekend to the woods outside are house..trails for 100's of kms over 600 lakes Bears moose duck deer beaver fox berries Trout bass perch along a chain of spring water feed run offs right out of a sandy rock pool ..filtered cold out of the rocks We still add it to a filter and its been tested..nothing harmful 25 years later Being native and knowing the land My family eats good drinks good..Free my son at 8 got his first moose and 5 hrs of trimming it for home Northern Ontairo is truly free
Subbed .. i like your channel Will you be doing edables in your area? I was just showing my son worse case problems in the woods and eatting whats around him Brich and maple trees and eatting behind the bark by cooking it slightly ..Making a bed out of pine tree branches to lift you off the cold ground (winter)
I live on the european continent ( UK? and Germany mostly ) and the river water is basically quite clean and free of deceases...as long as you drink liters of it....... I always boil my water and never had any problems....even the occasional dip into the river / lake for a fresh drink didnt harm me so far.......of course in other regions that might be trickier and requires a sophisticated filtration system...and boiling your water!
If you have near nothing to start with Boiling, Get a rock cut and grind hole or trench in a log with solid wood (no oak the tannin will make you sick) fill with water get a fire going get smooth rocks heat them up use sticks to move hot rocks to water add and remove rocks till water boils. Filtering, get a fire going burn wood collect black char crush to a powder get sand as clean as you can find and pebbles get a container poke a hole in bottom use some cloth cover the hole hold it in place with pebbles then fill with layers of char and sand save room to add water and have another container or just drink the stream as it falls. UV sterilization Clear plastic bottles fill them up, set them in direct sunlight for two or more hours
When someone gets giardia while out in the wilderness, it's usually not possible to determine how they got it. Some studies have blamed most cases on poor camp/cooking hygiene. So make sure others wash their hands, etc, too.
I have drank creek water in Indiana a few times and get sick every time(other than 1 time) for about a week .. but it takes a few days to kick in .... but I here if u can drink not off the top and not off the bottom of moving water u can avoid a lot of the floaters and sinkers ..so just using a straw can make a huge difference
I put a silk sock over the ceramic filter on the intake tube of my Katadyn to keep it from accumulating grot in the pores and extend the life of the filter.
Excellent video, but there's couple of things worth mentioning. First, boiling does not kill all bacteria - thermophilic bacteria survive up to around 122°C temperatures. Not that it's a problem, as only relatively very few bacteria are in any way dangerous to humans. Hospitals use autoclaves, essentially pressure cookers, to sterilize stuff at around 121°C for some 20 minutes. Some nasties like prions and some extreme microbes might survive even that. But those are so rare that it's irrelevant. An issue which is really relevant to water filters is that they can get clogged really easily. Almost every time I've used one in the wilderness, the filter has been almost completely clogged after pumping less than a litre. In many places, water naturally contains a lot of humus. Humus itself is not usually dangerous and is fine to drink straight. I prefilter should be helpful with that. Also note that there's a bit marketing in selling water filters and chemicals. In almost all places running water is usually fine to drink, at least in the cooler regions of the world, unless there is a dead animal upstream or something, which sometimes happens. People have lived in wilderness millions of years without filters, chemicals or even without boiling. If unsure about the general quality of water, treating the water is of course always a good and easy precaution to avoid trouble. So prepare to do it always when you can, but don't avoid drinking when you really need it.
Marko Grönroos My favorite part was when you brought up things that are not a problem, rare and irrelevant- according to you. So...when we're in the wilderness, should we also beware of dinosaurs, platypussies and bigfoot?
but what you fail to think about is we are so modernized that we would die! ( without filters ) "but don't avoid drinking when you really need it." by that statement alone could kill someone ( without filters or tabs ) so i'm going to stick with filters and tablets thank very much
The reason she says to drink water if you really need it, is b/c dehydration will kill you quicker than bacteria. If you were lost and there was a chance of getting out or being found in 72 hours, the better choice (lesser of 2 evils) is to drink. Severe dehydration can cause screwy thinking like being drunk.
Question: Fresh water can be obtained from Wild Grapevine. Nick the vine, don't sever it or you have destroyed your water source. So, the question is: can you only obtain drinking water from Wild Grape Vine in the Spring or Summer? I am presuming this is not possible in the dead of winter's freeze?
my way plastic funnel, gauze or lint, fine sand, activated charcoal, place gauze in bottom of funnel to block hole, add charcoal, top layer sand, place spout in container to catch water, pour water through filter, next boil filtered water, leave to cool, add water purifying tablet, leave long enough for tablet to work, ok drinkable water
Thanks for your video. Our local Utah search & rescue has for years used sublimed iodine crystals in small bottles. Water, even raw water is placed in the bottle & then the solution is used like regular iodine. Advantages are that it treats a ton of water (about 1000 gallons per small bottle) & that the iodine is pure. Not having the extra junk iodine usually contains makes the water taste better.
And on a humorous side note. I transported someone to the hospital and when I asked the person their name, I was told her first name was "E-coli." hyphen included. I thought after years of sirens in the ears I heard her wrong so I asked her to spell it and yes I did hear her correctly. Of course, I had to ask her how did she get that name. I was told her mother had e-coli when she was born. Just when you thought you heard it all. lol Peace, Reese
About the boiling part, no, water boils in higher elevation and at a lower temperature. Water boils at 100C at sea level but at lower temperatures at higher elevation due to lower atmospheric pressure. What's important is for the water to reach 100C to kill as much of the bacteria and viruses as possible, not the boil.
Thaks for the comment. If we are going to get technical you really only need to get water to 149 degrees F in order to kill the bacteria and parasites. But since most people dont carry water thermometer or a Wapi then we use the visual indicator of boiling the water to KNOW that it is safe. Because even boiling water at 28000 ft has reached more than 149 degree F. And at various lower elevations it has surpassed that point and is also good to go.
Thank you for this vid, lots of people need to know this stuff. two things 1. how is it that people live up mountains & in the wilderness drinking water straight from rivers & streams & never seem to get sick? do you build up a resistance to germs & nasty's in the water? 2. it's the 7 p's so - proper planning preparation prevents piss poor performance!
Thanks. I modified it to the 6 P's when i started teaching it to my kids. :). As far as resistance yes it is possible to do over a long period of time. However, it is NOT recommended to try to build up an immunity intentionally because there are potential health concerns in doing so. also this video is geared towards emergency wilderness survival. In these cases always purify water before drinking if at all possible.
When I was a kid we ran a cattle ranch in a remote part of Utah and owned more than 500 head ourselves. There was a stream that ran through our base camp where we had all of the conveniences and amenities and we would take our water from it. Quite often we would drink it straight up with no ill effects, just throw down a handful of grass to filter out the insects and take your fill. Either we all had AMAZING constitutions or the water quality has changed over the last 40 years because I hiked back into the ruin of our once beloved base camp (the Sierra club took over the area and screwed it up) and got a sample of the water for testing. What came back looked like "death juice", one mouthful of this free-flowing happy punch would probably land you in the hospital for at least two nights. So what has changed? has all of our water suddenly become undrinkable without first treating it or have WE become so dependent on a sterile environment that now we can't live any other way. I think for the time being that I'll do what I always do and blame it on food additives and commercially raised, growth hormone contaminated meat killing off our body's ability to withstand adverse conditions and our own mindset that a hard day is the exhausting 22 minute workout at the gym. Damn, have we gotten soft.
Yep I hear ya. I think it is a bit of both. Also not all ground water is contaminated. But it is impossible to tell by looks alone. So better to be safe than sorry id say. Boiling is pretty easy and gives ya a good excuse to have a nice manly fire! Lol
Well, there wasn't a problem with the water until the Sierra club got their asshole lawyers to shut us down then used heavy equipment to block all access to the canyon by vehicle then posted it no trespassing and enforced it with the sheriff arresting everyone on the "wrong side" of the blockade but hey, the water was fine before that so what did these environmentalist retards do? To see the canyon now breaks my fucking heart, it looks like the ass end of hell. At least when we were there we kept the canyon in the state we found it in, we cut out the deadfall every summer, planted natural grass seed to keep the lower end of the ecosystem from drying out and dying out, maintained navigable roads, kept water erosion from slicing chunks out of the mountain and moved our herd from place to place to prevent overgrazing and every rancher we knew did the same so exactly how are our ranches to blame except in the delusional mind of some vegan tree hugger?
Something I have always wondered about; Is this a relatively recent problem? (last 75years?) How did the Native Americans deal with this? How did Lewis and Clarke deal with it? You are told not to drink water, even from high mountain glacial streams now.
Yep since the development of city water purification systems is when this started. If you had grown up drinking untreated water from natural sources then you are much less likely to have issues. High mountain glacial streams are not extremely likely to have bacteria or virus issues however the high silt content can be an issue is large quantities.
The seriousness of dehydration - wow! I'm reading a medical book/bible right now, by Dr. Bones and nurse Amy (The Survival Medicine Handbook, 3rd edition), and it stated that the thirst mechanism kicks in after losing only 1% of your water content. ONLY 1%! At about 4% water loss you are beginning to make very poor decisions, becoming lethargic, agitated, getting a bit delirious probably...and by 6% water loss your vital organs are going bezerk and can no longer contribute to regulating your core body temperature...and they begin to shut down. At that point, oral hydration will not be sufficient to re-hydrate; you need an intravenous solution to save yourself. AKA fatal. Drinking water at that point is simply not enough to replace what your vital organs have expended, and require replenishment of. A very scary reality. Hyperthermia and hypothermia require clean, safe fluids, and lots of them. The importance of hydration simply can not be overstated, nor can the filtering or sterilization processes. This is an excellent video. So glad I saw this. Gonna' watch it again, right now, and take a few notes.
I have heard this before, but that reference lacked any sources. Thank you for posting your source. As part of my state Firearm Safety and Hunter Education program that I volunteer as an instructor, the syllabus has a module for field survival. The first 2 parts to survival maintaining psychological composure to avoid panicking, and then to evaluate what you do know and make a plan based on your given situation. If you also happen to be dehydrated and your decision making ability is compromised, that reduces your ability survive and return home. Hydration really needs to happen before and during venturing out in the wilderness.
@@chrisgraham9110 man...I had to get back to you, Chris. I was re-reading in that medical handbook the other day, on the section dealing with hydration/dehydration, and I made a bit of an error that I want to correct for you; the stages are mild (2% water loss/5% of body weight), moderate (4% water loss/10% of body weight), and severe. Severe dehydration is around 6% water loss (more than 10% of body weight), BUT it is around 20% of water loss when we lapse into a coma. 6% loss is most certainly not good - we are already at a very dangerous point in dehydration and need to seek water/fluids and medical attention immediately, but I was unintentionally misleading when I stated that at 6% we fall into a coma. We do not, at least not at that point. Most likely dangerously close anyway, but it's closer to 20% water loss that causes us to go into shock and coma. That is on page #200, and I am so glad I re-read that page. As soon as I realized this I had to contact you again and correct my error. Glad I caught it!! MAN. Anyway, hope all is well, play safe and sound, and be good!

I drank from a stream that looked similar to the one in the back ground for almost a year without boiling it. Never came down with any symptoms. It was about 10' across at the point where we drew from & 4"-6" deep with a solid limestone creek bed. Above that point was probably 4- 5 springs that bubbled up in the creek. The only problem we had was the amount of lime that built up on the inside of our cooking pots & it didn't taste very good with all the lime in it. We eventually found a spring that we started drawing water out of. Not sure why we didn't get sick.
Well it actually makes sense. If it was fed by a spring that water is typically ok to drink ( there are tons of variables though) the water likely didnt have a chance to get infected yet. But it is always a gamble.
Dr. Anja, I teach survival also, and the 'rule of 3' is inaccurate , here's why: It conditions people to think in terms of limits that are simply not true for many people, especially people who set their own limits based on experience. For example, I can hold my breath for 5 minutes, I have fasted without food or water for six days and have also fasted with just water twice for 23 days. 30-day fasts on water are not uncommon. The shelter rule applies, however, in extreme weather. I mention these not to brag but to point out that people should not merely accept limits imposed by some arbitrary 'rule' made up by somebody which others now repeat like it's some permanent limit of the human body. Survival is, in some cases, more mental than physical, so empower people with accurate information that does not impose limits.
If you teach survival you should know that the rule of 3s is not to set a limit on how long you can go as a definite tine frame. But as an easy way to help the survivor remember what their priorities should be. It is an example to demonstrate that exposure will kill you first. Dehydration is the second leading killer and hunger is far less common so food is a last priority.
good video, I drank water from a high stream, by the time i got back i was sick as a dog and was out with a fever for 3 days. Luckily i was at a pharmacist house. Also walked thru a ground hornets nest and was stung about ten times (not allergic). As a kid we would walk thru creeks and streams for hours. Never had any other bad experiences. Also have been covered with ants from low hanging branches in a creek. Hiked to the top of Yosemite fall and back down with no water (6 to 8 hours). The good old days.
Some real good basic information. Potassium permanganate treats water in municipal water plant but is iffy for people on the trail. As this is survival you will take the proper equipment with you to treat water. The WAPI is a great tool to make sure water is pasteurized. One advantage to boiling or chemical treatment is that it can treat your water bottle at the same time. Bacteria will begin to build up near the lip of your bottle. If you treat water chemically bring lemon or lime powder and pour a small amount in your water. This will cover the chemical taste. Chewable vit C will help as will vinegar but I doubt many could drink vinegar tasting water, although the Romans treated water with vinegar. One other important thing to remember is to filter all water at least through a folded handkerchief first. Even fast water has floating contaminants. By the way fuel in the desert is hard to come by and in many areas there are no burn restrictions.
No water doesn't just evaporate as soon as it starts to boil. It happens slowly. You only have to bring the water to a good hard boil for less than a minute. But yes if you capture the steam and recondense it the water will also be safe. That is called distilling it.
Boiling water is not that problematic. 5 liter billy 5 to 10 dollars. Weigh bugger all take 2 if you need a lot. Take a pad and you can carry your 2nd one with 4lt sealed boiled as you leave walking along. Boil it. Sit it in the water source to cool. Take that time to air your feet and change your sox. Ask any soldier. Aired feet clean sox makes the rest of your march hike less fatiguing. Cheap chinese water bladders, as are 1lt pet bottles,are useful. You can always carry contaminated water boil it later as longs as you are careful and ensure those bottles or bladders arent used for clean water. Ive been hiking as a teen since mid 70s. Ive never had a water filter, simply boiled water in tin cups and at times used empty bean coffee cans to boil more water faster. It is realy unnecessary kit. A filter bag ( drill cotton) to filter particals and boil is all you need. And some time...and isnt that the reason you are out there in tyhe first time, unwind relax take the time to be interested in nature and look at it.
But what about down here in Texas? All of the Rivers near me are a DEEP brown (honestly can't see through it). I don't think boiling the water would do much for that.
Good intro into water purification but I would of talked a little about pasteurization and solar disinfection as possible methods considering the how popular the Plastic Nalgine bottles were and still are. There is a reason that the wilderness survival practitioners have flocked to the stainless steel water bottles and that is for boiling the water in greater volumes then a nesting cup would allow.
Your forgetting the most overlooked and arguably the option that just makes the most sense. If covid has thought me anything, it's that alcohol is amazing. See when i drink the alcohol it lets me forget that I chose to pack only pack vodka and beef jerky. At some point in the trip it becomes extremely portable too, when theres enough alchohol in your stomach you don't even need to treat the water, it does it all for you hands free.
2 liters of water at rest? that seems way high! ( i'm lucky if i can get 1 liter down ) also on the tablets .... if they are not made for long term use then why are they sold in high amounts?
Good general education video. After obtaining water from its source and ensuring there is no large particulates, I was taught that boiling is best, chemical treatment second and filterIng third. If a person wants to UV sterilize you can put your water in a clear water bottle or bag and expose it to direct sunlight for a day. Just saying...... JJ, best wishes to you and your family for the holiday's.
Thanks Judge! Right back at ya! I did a video a while back on Solar disinfection. The only thing I will add is that for some reason they say it should be bottle with a recycling code of 2 if I remember right to get 100% results.
Iodine won't kill crypto....only chlorine dioxide or boiling. If you are in a rainy environment boiling may not be an option or a fire may not be possible. I like filters okay but anything mechanical can fail or clog. Best to have a backup as well. The downside to chlorine tablets is the 4 he wait time.....the 2 part drops are much faster but more complicated.
very good information, and good presentation. One thing, and this is a long time pet peeve of mine. there are many many quotes you could have used if the 5th P offended, but it is the 7 P's not 6. proper prior planning prevents PISS poor performance. if you are using an established saying, or quote, use the whole thing. some people will slam me for being petty here, but it REALLY bothers me when this type of thing is done.
Its kinda funny a bunch of people give me crap about the 6 Ps. Of course I learned the 7 Ps in the military. However when I started teaching it to my 10 year old daughter I modified it to the 6ps. So if people don't like it the can just deal with it or not watch. It will always be the 6ps on this channel. I do appreciate you watching, but honestly don't really give a crap about what annoys you. :)
great video vary informative. my profession is treating Water and Wastewater, I'm not sure if it was mentioned in a previous comment or not but UV does not kill bacteria or organisms. but it does make the bacteria and organisms so that they can't reproduce.
You mention 3 contaminants: 2 parasites and 1 bacteria. So does that mean using filters will do the job as far as removing those harmful critters and the viruses are not a problem? Nice video. I'll check more of them out.
+Giacomo Calabrese filters will not take out viruses they are too small. In the US there are very few water borne viruses in ground water. So it is not typically as big of a problem as bacteria and protozoa and cysts. But of you want to be sure boiling is always best.
+Giacomo Calabrese yeah a lot do claim that but it is an advertising scam. They may remove 99.9% of viruses in the US. Only because there are very few here. Lol
+Reality Survival: Doctor, I've always heard you had to boil water for at least 20 minutes to kill all bacteria. If I understood correctly, you said to just bring it to a good hard boil. Would appreciate if you clarified HOW LONG TO BOIL WATER.
The big problem is when you dont have very clear water. None of these methods except using a filter, will help you get rid of bacteria and viruses that are imbedded inside little pieces of dirt and debries. They will survive boiling, UV and chemical treatment. Everyone should have some kind of a filter (e.g. drip coffee filter, bandana, etc.) to keep out contaminants.
It is always a good idea to prefilter water of it is needed. However, I would love to see your source for saying that they can survive boiling. I have never heard that before. I have also drank a lot of pretty nasty boiled water with very heavy turbidity and never had any issues. Throw us a link if you can find it! Id love to take a look and set the record straight. Thanks jj
water.epa.gov/drink/emerprep/emergencydisinfection.cfm#method The government says you should filter cloudy water through some material before boiling. I believe it is because of what I mentioned above. If I find another source I'll upload it.
What a delightful person you are. It was fun listening to you. :) I have a question. If you do get some symptoms while out there and you can't get treatment? Is it true that you can crush some charcoals from a previous fire and mix that into some boiled water and this can kill the bugs or bacteria in your intestines?
Sort of. My understanding is that the charcoal won't actually kill the bacteria in your gut but will absorb a portion of it, there by lessoning the symptoms. It also helps to thicken the stools. However you should consult a doc on what the right ratio of charcoal to water would be. Also make sure not to confuse charcoal and wood ash, huge difference with nearly opposite effects.
+Reality Survival I can't believe you got back to me so quickly. Thanks so much. I know you must be busy and the post was in 2014. I heard that the charcoal acts like a 'regular Britta-type-water-filter would'. Thanks again for the quick response. I need to check to see if you have other videos. You 'Represent', very well. Take care.
Thank you Sir! Yep this is my channel. The Doctor was just a special guest. I do my best to answer each comment. I have close to 400 vids now I think. Enjoy as many of them as you like!
Great video! One small clarification... you do not actually have to bring water to a "hard boil" to kill pathogens. Pasteurization is sufficient. Boiling requires bringing water to 212 degrees F while pasteurization only requires you to bring your water to 141 degrees F (160F is the industry standard pasteurization temp, but all waterborne pathogens die quickly at 141 degrees F) . While boiling is a terrific visual indicator, a water pasteurization indicator can tell you when your water has reached pasteurization temps without having to waste the extra fuel to bring your water to a full "hard boil". WAPIs (water pasteurization indicators) are tiny and cheap. Why does this distinction matter? Well, because when using a fuel powered stove, the amount of fuel you must use to bring water up to 200 degrees F... taking your water from 200 degrees F to 212 degrees F requires that same amount of fuel... AGAIN!! Most people don't realize that. So when fuel is a precious resource, pasteurization is advantageous over boiling in that it requires less than half the fuel consumption to achieve. And... it works! Just as Louis Pasteur! :) Thanks for reading. I hope you don't mind the long-winded yet well-intended feedback! Thanks for the great video!
Yep we didnt go into pasteurization on purpose because most people dont carry a thermometer or a WAPI or whatever they are called to tell when it is done. But you are correct that is another way to do it for sure! Thanks for watching!
What i know, from my poor knowledge of survival, is that running water is most likly more clean than water that stood still for some time,because moving water is better circulated. Groundwater is very clean because it was filter through the ground it runs. Rain is to my knowledge also very clean. Another thing is that our ancestors could endure much more hardship than we today. They would eat meat that we would consider rotten and therefor not touch it, so i can imagine that the bacteria and the parasites were not so much a problem because they were used to this stuff. And becouse of our "modern" society our bodys are more vulnerable than they ussed to be. Evolution is wierd sometimes. ^^
3 hours without shelter in extreme temperatures. Me: A bike commuter during winter with 1,5 h ride to work, currently suffering the worst Flu in my life. Still happy I don't live in a bad country so I can drink from a puddle.
I have seen other videos that say you can just leave a clear bottle of water in the sun for several hours and the uv from the sun light will kill the bacteria. what do you think about this method? the other thing I have seen is a portable solar stove you could use to eliminate the need for fuel
+John Latsch yep I have done a video on that as well. It is called the SODIS method. Works well as long as the water fairly clear and the sun is shining bright.
Great video ... 20 years ago i almost died from something called Weil's disease, because i was young, stupid and didn't treat my water, i'm very particular about sterilizing my water now. I have a couple of water filters, and never drink untreated water now,
No fluff. No BS. Concise and informative. Excellent presentation.
This should be taught in schools. How to dig a seep well, distill water, and make a filter in a situation like this. 90% of our survival situations come out of recreational activities, and 90% of those are done around water. No reason to ever dehydrate if you know how to obtain clean water. GREAT VIDEO.
And always remember if you have no other choice then to drink untreated water it is VASTLY better to drink from moving water rather then stagnant water. Given a little time and oxygen aerobic bacteria always out compete the more dangerous anaerobic bacteria.
True!
@Donald J Im gonna take a big shit in every stream i see just for u
@@livelife5763 what a jerk
@@RealitySurvivalI never filter fresh water and prefer to drink directly from lakes, rivers and streams. A healthy human body is the best natural filter system.
hint doc...fill ur bottle with the opening away (180') from the direction of water flow...less solids
Good stuff thanks for watching!
@coolguyhentaisenpai dont be a hater you know its good advice this obviously applies to running water doofus
@coolguyhentaisenpai
"Yeah?" ..Yes
"how does that work in a puddle?"
..it doesn't
"what if the stream is barely a dribble?"
..doesn't apply
"come on it's not a hint"
..hint aka tip or trick
"it's advice that's hardly helpful"
..it's helpful
you have been criticised frequently in life haven't you..
Be kind to yourself and others.
@coolguyhentaisenpai in a puddle their isn't water flow. your comment isn't valid.
Thanks for the idea, never thought of it
Boiling its still the best option, its cheap and 100% guaranteed to give you clean water every time. Just boil it on time while you are still not thirsty so that you dont have to drink it hot.
Filter then boil then it gets the big bits out too
Still doesn't do anything for chemical waste that has higher boiling point than water...
Sure it does if you use an activated carbon filter element.
@@AfterShockzPb that’s why having a good filter is key before boiling it.
@@AfterShockzPb There are also set ups you can make that let the water sit in sunlight (UV rays and heat both help kill bacteria and viruses while evaporating the water to help collect it) in a container and evaporate and collect onto a “lid” and drip into a clean container, so you have clean water.
Bonjour . Je suis Québécoise et parle Français. Je vais écrire en Anglais mais excusez mes fautes.
I do speak French so excuse my English fault.
This vidéo is so instructive and interresting that I did share it with my friends from different countries. Also I told them to read the comments because there are a lot to learn.
I am a retired nurse. And my best friend had a kdnney surgery for
Bosniak cell 4 . So I consider very much important for Her To know what is explain and reconize the déshydratation sarde.
THANK YOU SO MUCH To you and also To the people who did instructive comments.
This is a gift of GOD.
What about sticking the water in the sun for 5 hours would that not kill most bacteria?
Six hours. And yep I have a video on the SODIS method too.
Thank you for having the Doctor speak with us about the all important water purification. Hope to see more like this.
Very cool! Thanks.
A friend of mine picked it up and admonished me to 'always' filter my water. He said he spent several days in his tent. I don't remember him telling me how he got over it, or how he got out of the back country in such a state. We used to canoe camp and backpack together. He surprised me. I have a Katadyn Pocket ceramic filter.
To those who are wondering how people survived before filtration and boiling was used:
Most diseases that we get today come from doing things in close quarters: farming, living, defecating, etc. In the middle ages, pedestrians wore wide rimed hats in European cities to avoid getting hit by the poop that people threw out of their windows. Domesticated animals gave us many diseases as well, because we kept and still keep them unhealthy, close together, and sometimes the floor of their living spaces is made of their own feces.
So back to my point, we didn't get sick because most of these pathogens didn't exist yet, and most of these water sources were not contaminated yet. The earth was also much more temperate. Most of Africa and the Middle East was not desert before the 7th century. There were plants, streams, and ecosystems. Streams are natural water filters, they don't kill all bacteria and parasites, but the water flow keeps solids (metals, fungi, plants, etc) from accumulating. The source of the water upstream also matters, springs and fresh rainwater are much safer. People knew where to get their water back then too, because if somebody died from one water source, everybody else knew to avoid it from then on, and they saw the patterns of what safe water sources were like.
Although civilized humans have become cushioned, it isn't weak to take steps to avoid getting sick, just because our ancestors didn't have to do that.
Great video JJ Dr. Anja knows her stuff, and I hope to hear more. I also see you are tightening your transitions in the video with your edits. And a GOD shot ending lol. I miss you dude, but I am glad you have real quality guest speakers. Good luck in your life and education. Stay safe and hit dem books. :)
Thanks bro! I will be back on soon. I hope to get caught up on a bunch of videos over teh christmas break.
I like the idea of that UV thingy that purifies (or does it sterilize? Obviously, it doesn't actually filter the water) your water. Most all of us here have the means to boil our water and some of us have the means to filter our water (always a good thing!). For that UV pen I could see that being equipped with extra rechargeable batteries and a means of recharging them (i.e. a small solar cell charger like the ones they sell through Harbor Freight) would be a great way to go for powering that unit.

Excellent video with great practical advice - memorization aids such as the rule of "3" are very useful in a survival situation. Thank you for all the warnings about the water, I have been stuck drinking "running" water a few times in emergencies and became kind of "cavalier" about it - thank you for the cautions and personal experience. Ciao, L
Thanks for watching!
I just now stumbled upon this and found it to be very informative. I am currently residing in Ireland, and when out and about I would come across lots of the things talked about in the video. (Thumbs up for the editing and producing of the video.)
Excellent info for anyone who's freshly venturing out... including teaching little kids to not drinking while swimming! Happy Feet!!
Use a bandana over your water bottle as a pre-filter to stop the larger particles from getting in it as you fill it. Today ( 2016 , two years later ) there are several water bottles that you take the top off and remove the attached filtration system , then fill your bottle . put the filter in it and attach the top then drink. The part that touches your mouth never gets near the unfiltered water so it does not become contaminated from the untreated water. Three good ones that comes to mind are the Grayl and the Sawyer along with the Life Straw water filtration bottles. Cooking water gets boiled since you wanted a hot meal and there is no reason to filter it.
+Chuck Littleton Good stuff! Thanks!
Great video, it's good to hear someone who actually knows a thing or two about making water safe to drink. BTW there is a way to boil water on the go by using a quality MRE heater - fill it with water, seal it and stick it in your backpack, once activated they reach a rolling boil quite fast without the use of a flame, though waiting for your water to cool enough to drink is another matter.
Interesting idea! Ill have to give that a shot!
The one item almost never addressed concerning water purification
is the presence of toxins (these come in many forms an example being nitrates). While in many areas the probability of their presence is low, it is not zero. The problem is that they are difficult to detect and in many cases difficult to remove. Depending on the toxin their effect may be felt immediately or may be delayed for a long period depending on frequency of ingestion and amount ingested. Their effect can be mild to life threatening. Understanding the environment you are in and land use practices such as farming, mining, manufacturing and military use will give some indication about the possible presence of toxins.
For the above reason most water purifiers and filter manufacturers suggest in fact warn users that their products should not be used in salt water [sea water] or chemically contaminated water such as from mine tailing ponds or agricultural collection ponds. It's good advice Donald that you stated this.
@@LAPGOCHINSTRUCTOR I really enjoyed exploring the American parks, you learn quite quickly returning to the UK that there is a big difference between suspensions and solutions. Many places around me have arsenic contamination from old mine workings which would need a reverse osmosis filter to remove it (or a still)
Good video straight to the point and very informative. She being a doctor, working the search and rescue team and knowing the outdoors and teaching first aid lends confidence in her info. Thanks
At 2:24 she said it takes longer to boil at higher altitude, but with the lower pressure it boils at a lower temperature.
It does but if you see a hard rolling boil it will have reached a temp that is high enough to kill bacteria and viruses, etc.
Thank you for sharing those very important tips. Be safe out there. 🤗
No doubt others have mentioned this but, yes, water "boils" more readily at lower elevations than higher. That is, at 212F, sea level water will boil, but water at a height of say two miles, may not boil. It will still be the same temperature as the sea level water. The trick is if you are are looking for boiling activity as a sign of reaching the right temperature, you may have to re-calibrate.
Actually you have it backwards. Water boils at lower temps at higher elevations. But the reason looking for a hard boil works at all altitudes is because the water becomes pasteurized at temps that are below the boiling point at all reasonabke altitudes. www.google.com/url?sa=t&source=web&rct=j&url=www.fsis.usda.gov/shared/PDF/High_Altitude_Cooking_and_Food_Safety.pdf&ved=2ahUKEwjfit2gpfTcAhXRuFMKHZ6gCIUQFjACegQIZRAF&usg=AOvVaw1toSAelVdu-tpMjGiA6vhI
Great info JJ. At first I was thinking "wow, he had a really professional looking guest video," but then I realized you produced it. Great job man! You're taking your filming up a definite notch!
Growing up my father took me every weekend to the woods outside are house..trails for 100's of kms over 600 lakes Bears moose duck deer beaver fox berries Trout bass perch along a chain of spring water feed run offs right out of a sandy rock pool ..filtered cold out of the rocks We still add it to a filter and its been tested..nothing harmful
25 years later Being native and knowing the land My family eats good drinks good..Free my son at 8 got his first moose and 5 hrs of trimming it for home Northern Ontairo is truly free
+freakyflow good stuff. Thanks for sharing!
Subbed .. i like your channel Will you be doing edables in your area? I was just showing my son worse case problems in the woods and eatting whats around him Brich and maple trees and eatting behind the bark by cooking it slightly ..Making a bed out of pine tree branches to lift you off the cold ground (winter)
+freakyflow very cool! I appreciate it. I would like to do a series on edible plants that are found globally. Just need to get the time to do it!
I live on the european continent ( UK? and Germany mostly ) and the river water is basically quite clean and free of deceases...as long as you drink liters of it.......
I always boil my water and never had any problems....even the occasional dip into the river / lake for a fresh drink didnt harm me so far.......of course in other regions that might be trickier and requires a sophisticated filtration system...and boiling your water!
If you have near nothing to start with Boiling, Get a rock cut and grind hole or trench in a log with solid wood (no oak the tannin will make you sick) fill with water get a fire going get smooth rocks heat them up use sticks to move hot rocks to water add and remove rocks till water boils.
Filtering, get a fire going burn wood collect black char crush to a powder get sand as clean as you can find and pebbles get a container poke a hole in bottom use some cloth cover the hole hold it in place with pebbles then fill with layers of char and sand save room to add water and have another container or just drink the stream as it falls.
UV sterilization Clear plastic bottles fill them up, set them in direct sunlight for two or more hours
+Barskor1 thanks for sharing!
When someone gets giardia while out in the wilderness, it's usually not possible to determine how they got it. Some studies have blamed most cases on poor camp/cooking hygiene. So make sure others wash their hands, etc, too.
Great point!
pardon,you can have water boiled leave in stream.decanter to smaller containers if possible
to cool quicker
How about the method of capturing rainwater with a tarp that is funneled into a container as a natural way of purifying water?
I have another video on the subject. It is a good way to go if you have rain to work with.
Thats not a purification system...its a collection method.
Thank you for bringing this to us. I have the Katadyn Pocket.
You bet!
You can also filter water through your sock for extra flavour 🤣
😳😂
I have drank creek water in Indiana a few times and get sick every time(other than 1 time) for about a week .. but it takes a few days to kick in .... but I here if u can drink not off the top and not off the bottom of moving water u can avoid a lot of the floaters and sinkers ..so just using a straw can make a huge difference
Yeah that is not correct. You should purify the water no matter how it is collected if you dont want to get sick.
Another disadvantage of boiling is it does not remove toxins. I think that includes toxins that microbes produce.
My left ear enjoyed her voice
I put a silk sock over the ceramic filter on the intake tube of my Katadyn to keep it from accumulating grot in the pores and extend the life of the filter.
That is an excellent idea!
Invest in a Kelly Kettle. You'll have an efficient method of boiling water with an unlimited supply of fuel
Excellent video, but there's couple of things worth mentioning. First, boiling does not kill all bacteria - thermophilic bacteria survive up to around 122°C temperatures. Not that it's a problem, as only relatively very few bacteria are in any way dangerous to humans. Hospitals use autoclaves, essentially pressure cookers, to sterilize stuff at around 121°C for some 20 minutes. Some nasties like prions and some extreme microbes might survive even that. But those are so rare that it's irrelevant.
An issue which is really relevant to water filters is that they can get clogged really easily. Almost every time I've used one in the wilderness, the filter has been almost completely clogged after pumping less than a litre. In many places, water naturally contains a lot of humus. Humus itself is not usually dangerous and is fine to drink straight. I prefilter should be helpful with that. Also note that there's a bit marketing in selling water filters and chemicals. In almost all places running water is usually fine to drink, at least in the cooler regions of the world, unless there is a dead animal upstream or something, which sometimes happens. People have lived in wilderness millions of years without filters, chemicals or even without boiling. If unsure about the general quality of water, treating the water is of course always a good and easy precaution to avoid trouble. So prepare to do it always when you can, but don't avoid drinking when you really need it.
Marko Grönroos My favorite part was when you brought up things that are not a problem, rare and irrelevant- according to you. So...when we're in the wilderness, should we also beware of dinosaurs, platypussies and bigfoot?
lol
but what you fail to think about is we are so modernized that we would die! ( without filters ) "but don't avoid drinking when you really need it." by that statement alone could kill someone ( without filters or tabs ) so i'm going to stick with filters and tablets thank very much
The reason she says to drink water if you really need it, is b/c dehydration will kill you quicker than bacteria. If you were lost and there was a chance of getting out or being found in 72 hours, the better choice (lesser of 2 evils) is to drink. Severe dehydration can cause screwy thinking like being drunk.
Question: Fresh water can be obtained from Wild Grapevine. Nick the vine, don't sever it or you have destroyed your water source.
So, the question is: can you only obtain drinking water from Wild Grape Vine in the Spring or Summer? I am presuming this is not possible in the dead of winter's freeze?
0:29... 🤯 Holey 14,ooo calls for search and rescue...amazing
my way plastic funnel, gauze or lint, fine sand, activated charcoal, place gauze in bottom of funnel to block hole, add charcoal, top layer sand, place spout in container to catch water, pour water through filter, next boil filtered water, leave to cool, add water purifying tablet, leave long enough for tablet to work, ok drinkable water
All of that is not needed but sure cant hurt.
Thanks for your video.
Our local Utah search & rescue has for years used sublimed iodine crystals in small bottles. Water, even raw water is placed in the bottle & then the solution is used like regular iodine. Advantages are that it treats a ton of water (about 1000 gallons per small bottle) & that the iodine is pure. Not having the extra junk iodine usually contains makes the water taste better.
And on a humorous side note. I transported someone to the hospital and when I asked the person their name, I was told her first name was "E-coli." hyphen included. I thought after years of sirens in the ears I heard her wrong so I asked her to spell it and yes I did hear her correctly. Of course, I had to ask her how did she get that name. I was told her mother had e-coli when she was born. Just when you thought you heard it all. lol
Peace, Reese
Lol. Hilarious!
About the boiling part, no, water boils in higher elevation and at a lower temperature. Water boils at 100C at sea level but at lower temperatures at higher elevation due to lower atmospheric pressure. What's important is for the water to reach 100C to kill as much of the bacteria and viruses as possible, not the boil.
Thaks for the comment. If we are going to get technical you really only need to get water to 149 degrees F in order to kill the bacteria and parasites. But since most people dont carry water thermometer or a Wapi then we use the visual indicator of boiling the water to KNOW that it is safe. Because even boiling water at 28000 ft has reached more than 149 degree F. And at various lower elevations it has surpassed that point and is also good to go.
Thank you for this vid, lots of people need to know this stuff. two things 1. how is it that people live up mountains & in the wilderness drinking water straight from rivers & streams & never seem to get sick? do you build up a resistance to germs & nasty's in the water? 2. it's the 7 p's so - proper planning preparation prevents piss poor performance!
Thanks. I modified it to the 6 P's when i started teaching it to my kids. :).
As far as resistance yes it is possible to do over a long period of time. However, it is NOT recommended to try to build up an immunity intentionally because there are potential health concerns in doing so. also this video is geared towards emergency wilderness survival. In these cases always purify water before drinking if at all possible.
***** Oh I get it! that's cute.
Take care stay safe.
When I was a kid we ran a cattle ranch in a remote part of Utah and owned more than 500 head ourselves. There was a stream that ran through our base camp where we had all of the conveniences and amenities and we would take our water from it. Quite often we would drink it straight up with no ill effects, just throw down a handful of grass to filter out the insects and take your fill. Either we all had AMAZING constitutions or the water quality has changed over the last 40 years because I hiked back into the ruin of our once beloved base camp (the Sierra club took over the area and screwed it up) and got a sample of the water for testing. What came back looked like "death juice", one mouthful of this free-flowing happy punch would probably land you in the hospital for at least two nights. So what has changed? has all of our water suddenly become undrinkable without first treating it or have WE become so dependent on a sterile environment that now we can't live any other way. I think for the time being that I'll do what I always do and blame it on food additives and commercially raised, growth hormone contaminated meat killing off our body's ability to withstand adverse conditions and our own mindset that a hard day is the exhausting 22 minute workout at the gym. Damn, have we gotten soft.
Yep I hear ya. I think it is a bit of both. Also not all ground water is contaminated. But it is impossible to tell by looks alone. So better to be safe than sorry id say. Boiling is pretty easy and gives ya a good excuse to have a nice manly fire! Lol
***** well....it just ain't a night in the hills without a campfire ;-)
billybobjojack macoy
yes environmental degradation is a terrible problem especially out west. Cattle ranches are a prime cause.
+oxycrimson thanks for watching!
Well, there wasn't a problem with the water until the Sierra club got their asshole lawyers to shut us down then used heavy equipment to block all access to the canyon by vehicle then posted it no trespassing and enforced it with the sheriff arresting everyone on the "wrong side" of the blockade but hey, the water was fine before that so what did these environmentalist retards do? To see the canyon now breaks my fucking heart, it looks like the ass end of hell. At least when we were there we kept the canyon in the state we found it in, we cut out the deadfall every summer, planted natural grass seed to keep the lower end of the ecosystem from drying out and dying out, maintained navigable roads, kept water erosion from slicing chunks out of the mountain and moved our herd from place to place to prevent overgrazing and every rancher we knew did the same so exactly how are our ranches to blame except in the delusional mind of some vegan tree hugger?
Great video. I’m curious about more backstory regarding the improper food prep. What was it you did that infected the food?
One of my favourite videos. Thank you! Added to my collection.
Thanks!
Something I have always wondered about; Is this a relatively recent problem? (last 75years?) How did the Native Americans deal with this? How did Lewis and Clarke deal with it? You are told not to drink water, even from high mountain glacial streams now.
Yep since the development of city water purification systems is when this started. If you had grown up drinking untreated water from natural sources then you are much less likely to have issues. High mountain glacial streams are not extremely likely to have bacteria or virus issues however the high silt content can be an issue is large quantities.
The seriousness of dehydration - wow! I'm reading a medical book/bible right now, by Dr. Bones and nurse Amy (The Survival Medicine Handbook, 3rd edition), and it stated that the thirst mechanism kicks in after losing only 1% of your water content. ONLY 1%! At about 4% water loss you are beginning to make very poor decisions, becoming lethargic, agitated, getting a bit delirious probably...and by 6% water loss your vital organs are going bezerk and can no longer contribute to regulating your core body temperature...and they begin to shut down. At that point, oral hydration will not be sufficient to re-hydrate; you need an intravenous solution to save yourself. AKA fatal. Drinking water at that point is simply not enough to replace what your vital organs have expended, and require replenishment of. A very scary reality. Hyperthermia and hypothermia require clean, safe fluids, and lots of them. The importance of hydration simply can not be overstated, nor can the filtering or sterilization processes. This is an excellent video. So glad I saw this. Gonna' watch it again, right now, and take a few notes.
I have heard this before, but that reference lacked any sources. Thank you for posting your source. As part of my state Firearm Safety and Hunter Education program that I volunteer as an instructor, the syllabus has a module for field survival. The first 2 parts to survival maintaining psychological composure to avoid panicking, and then to evaluate what you do know and make a plan based on your given situation. If you also happen to be dehydrated and your decision making ability is compromised, that reduces your ability survive and return home. Hydration really needs to happen before and during venturing out in the wilderness.
@@chrisgraham9110 man...I had to get back to you, Chris. I was re-reading in that medical handbook the other day, on the section dealing with hydration/dehydration, and I made a bit of an error that I want to correct for you; the stages are mild (2% water loss/5% of body weight), moderate (4% water loss/10% of body weight), and severe. Severe dehydration is around 6% water loss (more than 10% of body weight), BUT it is around 20% of water loss when we lapse into a coma. 6% loss is most certainly not good - we are already at a very dangerous point in dehydration and need to seek water/fluids and medical attention immediately, but I was unintentionally misleading when I stated that at 6% we fall into a coma. We do not, at least not at that point. Most likely dangerously close anyway, but it's closer to 20% water loss that causes us to go into shock and coma. That is on page #200, and I am so glad I re-read that page. As soon as I realized this I had to contact you again and correct my error. Glad I caught it!! MAN. Anyway, hope all is well, play safe and sound, and be good!

Awesome video, JJ. Great guest.
I drank from a stream that looked similar to the one in the back ground for almost a year without boiling it. Never came down with any symptoms. It was about 10' across at the point where we drew from & 4"-6" deep with a solid limestone creek bed. Above that point was probably 4- 5 springs that bubbled up in the creek. The only problem we had was the amount of lime that built up on the inside of our cooking pots & it didn't taste very good with all the lime in it. We eventually found a spring that we started drawing water out of. Not sure why we didn't get sick.
Well it actually makes sense. If it was fed by a spring that water is typically ok to drink ( there are tons of variables though) the water likely didnt have a chance to get infected yet. But it is always a gamble.
Awesome video, luckily when I picked up giardia I had access to Oregon grape and made a tea from the roots and that took care of the problem.
Ok I subbed too after checking your other vids good stuff.
Thanks! i appreciate it!
no probs!
Good info no crap strate to the point,I respect that Thank a you a bunch!!!
Dr. Anja, I teach survival also, and the 'rule of 3' is inaccurate , here's why: It conditions people to think in terms of limits that are simply not true for many people, especially people who set their own limits based on experience. For example, I can hold my breath for 5 minutes, I have fasted without food or water for six days and have also fasted with just water twice for 23 days. 30-day fasts on water are not uncommon. The shelter rule applies, however, in extreme weather. I mention these not to brag but to point out that people should not merely accept limits imposed by some arbitrary 'rule' made up by somebody which others now repeat like it's some permanent limit of the human body. Survival is, in some cases, more mental than physical, so empower people with accurate information that does not impose limits.
If you teach survival you should know that the rule of 3s is not to set a limit on how long you can go as a definite tine frame. But as an easy way to help the survivor remember what their priorities should be. It is an example to demonstrate that exposure will kill you first. Dehydration is the second leading killer and hunger is far less common so food is a last priority.
Better to work to beat those limits than waiting only to find out you're running out of time to fulfil the needs!
good video, I drank water from a high stream, by the time i got back i was sick as a dog and was out with a fever for 3 days. Luckily i was at a pharmacist house. Also walked thru a ground hornets nest and was stung about ten times (not allergic). As a kid we would walk thru creeks and streams for hours. Never had any other bad experiences. Also have been covered with ants from low hanging branches in a creek. Hiked to the top of Yosemite fall and back down with no water (6 to 8 hours). The good old days.
Ahh the good ole days! Lol. Thanks for watching!
Very good video! Thank you.
You bet! Thanks for watching!
Some real good basic information. Potassium permanganate treats water in municipal water plant but is iffy for people on the trail. As this is survival you will take the proper equipment with you to treat water. The WAPI is a great tool to make sure water is pasteurized. One advantage to boiling or chemical treatment is that it can treat your water bottle at the same time. Bacteria will begin to build up near the lip of your bottle. If you treat water chemically bring lemon or lime powder and pour a small amount in your water. This will cover the chemical taste. Chewable vit C will help as will vinegar but I doubt many could drink vinegar tasting water, although the Romans treated water with vinegar. One other important thing to remember is to filter all water at least through a folded handkerchief first. Even fast water has floating contaminants. By the way fuel in the desert is hard to come by and in many areas there are no burn restrictions.
Good stuff! Thanks!
Doesn't boiling water evaporate it? If the evaporated water was recovered...would it be safe to drink?
No water doesn't just evaporate as soon as it starts to boil. It happens slowly. You only have to bring the water to a good hard boil for less than a minute. But yes if you capture the steam and recondense it the water will also be safe. That is called distilling it.
Boiling water is not that problematic. 5 liter billy 5 to 10 dollars. Weigh bugger all take 2 if you need a lot. Take a pad and you can carry your 2nd one with 4lt sealed boiled as you leave walking along. Boil it. Sit it in the water source to cool.
Take that time to air your feet and change your sox. Ask any soldier. Aired feet clean sox makes the rest of your march hike less fatiguing.
Cheap chinese water bladders, as are 1lt pet bottles,are useful. You can always carry contaminated water boil it later as longs as you are careful and ensure those bottles or bladders arent used for clean water.
Ive been hiking as a teen since mid 70s. Ive never had a water filter, simply boiled water in tin cups and at times used empty bean coffee cans to boil more water faster.
It is realy unnecessary kit. A filter bag ( drill cotton) to filter particals and boil is all you need.
And some time...and isnt that the reason you are out there in tyhe first time, unwind relax take the time to be interested in nature and look at it.
No one said boiling water is problematic. She just covered the pros and cons pf each method.
Try at 2.50 ..the other problem with boiling...
You're a doll! Not going to lie, you make not boiling water sound as bad as drinking sea water
But what about down here in Texas? All of the Rivers near me are a DEEP brown (honestly can't see through it). I don't think boiling the water would do much for that.
Good intro into water purification but I would of talked a little about pasteurization and solar disinfection as possible methods considering the how popular the Plastic Nalgine bottles were and still are. There is a reason that the wilderness survival practitioners have flocked to the stainless steel water bottles and that is for boiling the water in greater volumes then a nesting cup would allow.
Very informative! Great video!
An excellent presentation. Thank you, Dr. Whittington. Appreciate your` sharing this knowledge. (Montana).
This is critical knowledge for those of us who love the wilderness. Thanks.
You bet! Thanks for watching!
I filter with sawyer mini and boil just to be sure. Nice and informative vid thank you
Well that will work but you certainly dont need to do both! But it sure doesnt hurt anything.
+Reality Survival Better safe than squirting haha
Lol! Fo show!
Your forgetting the most overlooked and arguably the option that just makes the most sense. If covid has thought me anything, it's that alcohol is amazing. See when i drink the alcohol it lets me forget that I chose to pack only pack vodka and beef jerky. At some point in the trip it becomes extremely portable too, when theres enough alchohol in your stomach you don't even need to treat the water, it does it all for you hands free.
Lol
Good info, well presented, easy to lisen to voice. Thanks Dr. Anja.
+Eli Whitney thanks for watching!
Awesome video, very clear and to the point. Great info. Thanks for sharing
Best idea is to filter and boil. Tea or coffee are recommended.
2 liters of water at rest? that seems way high! ( i'm lucky if i can get 1 liter down )
also on the tablets .... if they are not made for long term use then why are they sold in high amounts?
Tablets are ideal for a bug out bag especially when you have a 72 hour bag and you lack space for a kettle or cooking set.
Well done.
+WIZARDWERX thank you!
Good general education video. After obtaining water from its source and ensuring there is no large particulates, I was taught that boiling is best, chemical treatment second and filterIng third. If a person wants to UV sterilize you can put your water in a clear water bottle or bag and expose it to direct sunlight for a day.
Just saying......
JJ, best wishes to you and your family for the holiday's.
Thanks Judge! Right back at ya! I did a video a while back on Solar disinfection. The only thing I will add is that for some reason they say it should be bottle with a recycling code of 2 if I remember right to get 100% results.
Iodine won't kill crypto....only chlorine dioxide or boiling.
If you are in a rainy environment boiling may not be an option or a fire may not be possible.
I like filters okay but anything mechanical can fail or clog. Best to have a backup as well. The downside to chlorine tablets is the 4 he wait time.....the 2 part drops are much faster but more complicated.
Great 👍 stuff to know 👍
very good information, and good presentation. One thing, and this is a long time pet peeve of mine. there are many many quotes you could have used if the 5th P offended, but it is the 7 P's not 6. proper prior planning prevents PISS poor performance. if you are using an established saying, or quote, use the whole thing. some people will slam me for being petty here, but it REALLY bothers me when this type of thing is done.
Its kinda funny a bunch of people give me crap about the 6 Ps. Of course I learned the 7 Ps in the military. However when I started teaching it to my 10 year old daughter I modified it to the 6ps. So if people don't like it the can just deal with it or not watch. It will always be the 6ps on this channel. I do appreciate you watching, but honestly don't really give a crap about what annoys you. :)
great video vary informative. my profession is treating Water and Wastewater, I'm not sure if it was mentioned in a previous comment or not but UV does not kill bacteria or organisms. but it does make the bacteria and organisms so that they can't reproduce.
+Bradley Dick interesting!
You mention 3 contaminants: 2 parasites and 1 bacteria. So does that mean using filters will do the job as far as removing those harmful critters and the viruses are not a problem? Nice video. I'll check more of them out.
+Giacomo Calabrese filters will not take out viruses they are too small. In the US there are very few water borne viruses in ground water. So it is not typically as big of a problem as bacteria and protozoa and cysts. But of you want to be sure boiling is always best.
Thanks. I was confused when I read these filters claim to remove 99.9% of viruses.
+Giacomo Calabrese yeah a lot do claim that but it is an advertising scam. They may remove 99.9% of viruses in the US. Only because there are very few here. Lol
+Reality Survival: Doctor, I've always heard you had to boil water for at least 20 minutes to kill all bacteria. If I understood correctly, you said to just bring it to a good hard boil. Would appreciate if you clarified HOW LONG TO BOIL WATER.
+Honesty Fenix As you noted. You just have to bring it to a boil that is it.
Great information, professionally, sensibly, clearly, presented, Thanks Doc.
Thanks Steven!
The big problem is when you dont have very clear water. None of these methods except using a filter, will help you get rid of bacteria and viruses that are imbedded inside little pieces of dirt and debries. They will survive boiling, UV and chemical treatment. Everyone should have some kind of a filter (e.g. drip coffee filter, bandana, etc.) to keep out contaminants.
It is always a good idea to prefilter water of it is needed. However, I would love to see your source for saying that they can survive boiling. I have never heard that before. I have also drank a lot of pretty nasty boiled water with very heavy turbidity and never had any issues. Throw us a link if you can find it! Id love to take a look and set the record straight. Thanks jj

The government says you should filter cloudy water through some material before boiling. I believe it is because of what I mentioned above. If I find another source I'll upload it.
great information on the way you you need clean safe water to use and drink safely and not get ill.
+George Speck Thanks for watching!
What a delightful person you are. It was fun listening to you. :)
I have a question. If you do get some symptoms while out there and you can't get treatment? Is it true that you can crush some charcoals from a previous fire and mix that into some boiled water and this can kill the bugs or bacteria in your intestines?
Sort of. My understanding is that the charcoal won't actually kill the bacteria in your gut but will absorb a portion of it, there by lessoning the symptoms. It also helps to thicken the stools. However you should consult a doc on what the right ratio of charcoal to water would be. Also make sure not to confuse charcoal and wood ash, huge difference with nearly opposite effects.
+Reality Survival I can't believe you got back to me so quickly. Thanks so much. I know you must be busy and the post was in 2014.
I heard that the charcoal acts like a 'regular Britta-type-water-filter would'. Thanks again for the quick response. I need to check to see if you have other videos. You 'Represent', very well. Take care.
Thank you Sir! Yep this is my channel. The Doctor was just a special guest. I do my best to answer each comment. I have close to 400 vids now I think. Enjoy as many of them as you like!
Great video! One small clarification... you do not actually have to bring water to a "hard boil" to kill pathogens. Pasteurization is sufficient. Boiling requires bringing water to 212 degrees F while pasteurization only requires you to bring your water to 141 degrees F (160F is the industry standard pasteurization temp, but all waterborne pathogens die quickly at 141 degrees F) . While boiling is a terrific visual indicator, a water pasteurization indicator can tell you when your water has reached pasteurization temps without having to waste the extra fuel to bring your water to a full "hard boil". WAPIs (water pasteurization indicators) are tiny and cheap.
Why does this distinction matter? Well, because when using a fuel powered stove, the amount of fuel you must use to bring water up to 200 degrees F... taking your water from 200 degrees F to 212 degrees F requires that same amount of fuel... AGAIN!! Most people don't realize that. So when fuel is a precious resource, pasteurization is advantageous over boiling in that it requires less than half the fuel consumption to achieve. And... it works! Just as Louis Pasteur! :)
Thanks for reading. I hope you don't mind the long-winded yet well-intended feedback! Thanks for the great video!
Yep we didnt go into pasteurization on purpose because most people dont carry a thermometer or a WAPI or whatever they are called to tell when it is done. But you are correct that is another way to do it for sure! Thanks for watching!
Thank you very much for sharing your knowledge. Very much appreciated. :)
Thank you, Doctor, for the advice. Enjoyed listening to you.
+William Burr Thanks for watching!
Good Video JJ!
It's amazing that mankind has survived prior to water treatment.
What i know, from my poor knowledge of survival, is that running water is most likly more clean than water that stood still for some time,because moving water is better circulated. Groundwater is very clean because it was filter through the ground it runs. Rain is to my knowledge also very clean. Another thing is that our ancestors could endure much more hardship than we today. They would eat meat that we would consider rotten and therefor not touch it, so i can imagine that the bacteria and the parasites were not so much a problem because they were used to this stuff. And becouse of our "modern" society our bodys are more vulnerable than they ussed to be. Evolution is wierd sometimes. ^^
3 hours without shelter in extreme temperatures.
Me: A bike commuter during winter with 1,5 h ride to work, currently suffering the worst Flu in my life.
Still happy I don't live in a bad country so I can drink from a puddle.
Well let me add. thank you for the video. truly invaluable and much appreciated
+joe rogers you are very welcome! Take care.
EXCELLANT information and most valuable....thx
I have seen other videos that say you can just leave a clear bottle of water in the sun for several hours and the uv from the sun light will kill the bacteria. what do you think about this method?
the other thing I have seen is a portable solar stove you could use to eliminate the need for fuel
+John Latsch yep I have done a video on that as well. It is called the SODIS method. Works well as long as the water fairly clear and the sun is shining bright.
+Reality Survival I figure the SODIS method is good to know because no one plans on getting lost. all you need is an empty bottle
+John Latsch yep absolutely!
Great video ... 20 years ago i almost died from something called Weil's disease, because i was young, stupid and didn't treat my water, i'm very particular about sterilizing my water now. I have a couple of water filters, and never drink untreated water now,
I don't know what I was expecting, but this video was a lot better than what I expected!
Thanks!
thank you
You bet! Thanks for watching!
Very informative. Thanks for this.
lots of information here. great vid.
