Whether you are in an Urban or Field Environment, Water Will Need to Be Made Safe. In This Video We Discuss Different Ways To Do Just That. www.cdc.gov/healthywater/pdf/... www.cdc.gov/healthywater/emer... www.cdc.gov/healthywater/emer...
I am a licensed water treatment plant operator and chemist. Contact time is very important. The longer you wait before you drink the water, the less chemical you need to use. There are charts available showing required contact times. Prefiltering the water before chemical treatment is also important. In a survival situation, prefilters can be made from cloth, old bottles filled with sand and/or crushed charcoal from a fire. Charcoal can remove chlorine or iodine taste and odor as well as other tastes and odors that can't be filtered out.
I had a mentor when I was a teenager. He was a friend of my Dad's. He had been first a Marine then a SEAL in Vietnam. He always, filtered then boiled then put 2 drops of sodium hydrochloride in the water he put in his canteen. He said he saw too many fellow Marines get to death's door from amoebic dysentery. He told me he knew itvwas over kill; but it was also peace of mind. I personally filter then boil or filter and then treat. I prefer the filter/,boil as I have a hyper accute sense of smell and taste. It runs in my family. Anyway good video, well presented. Semper Fi
Took a chemistry course in college where we learned chemical titration proceedures. Used various brands of common household laundry bleach. All containers stated 5% bleach concentration. After titrating each brand, both name brands and store brands, none of the bottled bleach brands had the bleach concentrations stated on the label. All were between 2% to 4%. Mass production in factories may lead to inconsistent chlorine percentages. Shelf life does have an affect on chlorine content. Who knows how long these products sit in a warehouse before you buy it, then how long have you stored the bleach. Regardless, chlorine is an effective way to kill microbes. A microbiology class proved usefulness of chlorine.
amazingly through high school and college i was NEVER lucky enough to get to have/take a chemistry class. this cute girl i knew in college had one. she spent the whole semester just mixing chemicals while i had to deal with absolutely useless, migraine headache inducing classes like calculus which i promptly failed. depressingly, i recently found out that she's a psychiatrist. she's always had it easy in life
Good points. I never learned about chemical titration. But i did learn that chlorine bleach/NaClO does begin to decompose from the moment of manufacture and can significantly lose potency after about 6 months. And jugs of bleach, at least in North America, should have the batch manufacture date marked on them. In a pinch, if the jug is more than 6 months old, use double the directed amount of bleach.
Thank you for this very informative video. As an Army vet (7th ID) I learned these things in survival training, but your video helped my wife to better understand why I am so serious about water treatment, as we have lot of wilderness here in Wyoming. God bless you in all you do & Semper Fi!
Hello , and thank you for this instruction. I do have one thing to add and I hope you do not mind. When I was working in our lab at Long Beach Community College, we had to kill spores. We had to boil ( rolling boil ) water 5 times and in between each time, let the water cool, so the left over spores would come back. Boil again, let water cool, and so on. After the 5th boil, and the 5th cool down, we could find no more spores. Success.
Yes, this process is called Tindallization (after Tindall, the guy who discovered this) but for all intent and purposes boiling one time does the job, it kills all live/active protozoa, bacteria and viruses. Actually, water doesn't have to boil, get it to 165 Deg F (Pasteurization) and it will do the same as boiling, but you need a thermometer to find out, so the easiest method in the field is to bring to a rolling boil. It will be safe to drink. Ask anyone who's been in the bush and done this (myself included). For peace of mind, I would throw in a water disinfecting tablet (Chorine based), wait 30 mins and you're good to go. Make sure you use the right dosage: 1 tablet labeled "1 liter" into 1 liter of suspect water. Cheers
That was possibly the best video I have seen to date on the subject of drinking water and how to be sure it is acceptable. Straight to the point, concise, and no bullshitting. Thank you for the valuable information Corporal!
I say boil it for 4 minutes no matter where you are it'll get the job done. then add the appropriate amount of chemicals if you have them. And then run it all through a charcoal filter to remove any residual chemicals that were in the water to begin with and the ones that you added. it also improves the taste. I've been drinking charcoal filtered water for four years now since I came to the city I can't stand chlorine and I know it's not good for your gut beneficial bacteria. Thanks Cpl.
@@sbrazenor2 Chlorine is less soluble in water the warmer it gets, so the less you chill it the faster it will outgas. Of course, you can always chill it later.
I think that simply pouring water from a CLEAN glass to another CLEAN one some times, it helps to the bleach smell and taste to decrease almost to zero. I do with my municipality water here in Italy.
Thanks, my household was recently under a boil water order. I have a zero water filter, (which removes most chemicals) but it not safe with microbes "go figure". So I took my tap water added bleach let it sit for awhile then ran it through the filter to try and remove any chemicals from the bleach. It appears to be a good solution to boiling my drinking water. I am refining the method.
Pool shock is like 68% Calcium Hypochlorite...a solution of this (stir into a quart of water until no longer holds any more of the powder) give a HUGE potential for disinfection and it's VERY concentrated...same amount of drops...can't be TOO careful on killing the stuff that can/will cause you to crap yourself to death in a survival environment. You DON'T want to drink bad water...EVER! Gread video...Semper Fi Keep em coming!
By the way I know I'm late but wanted to say Happy Veterans Day Corporal .. I really appreciate your time, commitment and all you did for our country . I know only a bit of your story but I believe it was after 911 you were involuntarily brought back into service and you were shipped back to Iraq if my memory serves me well enough . Forgive me if I'm mistaken. But again thank you as well for all this amazing content and everything from the water purification tips to the incredible knot tying. Your channel is easily one of the most interesting channels around . In my opinion ... High quality content that's set apart from others . God bless sir
I've been told that if one goes with Iodine or Bleach, it might be a good idea to also carry probiotic tablets, as chemical disinfectants will supposedly wreck your microbiome, which can lead to some pretty nasty cramps.
Scowler the ammount of chlorine 4% you can safely add is about 4-5drops per ltr water. (So 8-10drops for 2%) More them that you can ge that yes. But... if you boil water you will remove chlorine. 75c chlorine will start to evaporate so bringing water to a boil will have removed it at that point.
I think the take away is if you have time use two methods if it’s a concern. I’ve always filtered then boiled, run the water through a rag with activated carbon into a .1 micron filter, then boil. Anything that gets to you after that gauntlet has earned the right to kill you.
Native from alberta Canada. Love your content Corperal.. I am learning things that most people forgot.. or have no desire to learn. But for myself and for my family and so I can show others. Thank you immensely.
As always, top notch content. You have an enviable way of clearly, succinctly and effectively conveying your skills and knowledge, combined with a very consistent method or format. Plus your videos are well shot, well framed, and well edited. You are also one of the few people to cite your sources and actually include screen shots etc. in your videos, where as many RU-vid channels at best either just tell you a web site to go look things up yourself, or at best, tuck a link into the description. You are very clear about whether your information is from a credible organization, a third party authority, or your own experiences and observations. It all adds up to what I feel is one of the most honest, hype and BS free reference sources on the Internet for the type of content you offer. To borrow a quote you often use yourself: (your channel) is outstanding! Thank you.
I absolutely agree. The only change I would request is maybe a clip-on or neck mic, as I had to put my ear up to my speaker when I was trying to write the info down. I am putting a hard copy book together for shft and when/if the Internet goes down. I do have a question, and I know this is off topic but when shift happens will we be tracked by our laptops/devices if we use them? I keep a file of encouraging pics and inspirational sayings on my laptop and I know I will need them when the grid goes down. Looking for a way to keep this stuff without tipping off the enemy to my location. Thoughts?
Well done. Like the you explained things. During my days in scouts we would do both. Boiling and a drop or 2 of bleach per gallon. It was taught to us Boiling was the best method. The bleach may have been over kill, but I am sure the adults did not want any of us kids getting sick.
I thought, in my callow youth, decades ago, that it was a _roiling_ boil, which achieves the exact opposite result from the desired one, as it muddies up the water. 😂😂😂 Another great vid and thanks for uploading!
Thank you, Corporal. I am always learning new methods of streamlining and making more high-speed my get home bag, bugout bag, and oh shit bag, among other contingency preps. Semper Fi, do or die.
good shit devil dog, i’ve never stumbled across this channel before but after hitting the subscribe button i’ll be sure to watch more of this excellence in the future.
You saw your video again on water those are some good points and it's a good idea that you pointed out there your source. You doing a good job with this don't give up keep thinking about putting the survival information together in your own book. Simplify Marine 💀💀
More expensive for sure, but ultra convenient if having to disinfect water daily in a 3rd world country while traveling is the SteriPen UV light. No need for chemicals or fire and claims to destroy 99.9% of microorganisms, viruses, bacteria and protozoa. I've been relying on it so I hope it's truly effective!
One thing to point out that people seem to forget about is 99 out of 100 times you can just drink the water. Unless it is thick, goopy swamp water almost always you will get away with it. Like here in Arkansas all the kids grow up swimming constantly in the creeks and rivers. Swallowing quarts of it. I bring this up because there are people every year who die of dehydration because they didn't have a way to disinfect the water in an emergency. If you are in a situation where it's drink the water straight from the creek or die, drink the water and deal with the possibilities later. Most protozoa and parasites won't even be a problem for a week or more on average. Better to spend a few weeks on the toilet after you get home then to die from dehydration after a few days because you didn't have any way/skills to disinfect it. You are better off drinking snake piss than nothing at all.
Coffee filters. Not to sanitize drinking water but the are cheap, easy to carry, multi purpose and washable for reuse. Pour debris filled water through them to get cleaner water before or after boiling. Use them also for a hand held berry bowl, to put loose tea or coffee in tying off with a string or clip. You can portion out rice or pasta, fold it into a packet and place down inside a thermos (insulated) and add boiling water. Wait an hour and you have a compact rice/pasta cake that can be wrapped and store as a prepared meal to warm up in a sauce pan with sauce & meat. It's less time consuming than waiting for your water to boil over an open flame and cook the items.
