- เผยแพร่เมื่อ 28 ส.ค. 2024
- Get out your prepper notes and document these changes to ensure you have the right calculations for using calcium hypochlorite to disinfect water in an emergency. Jay Whimpey, P.E., President of The American Civil Defense Association, has run some calculations that suggest a higher amount of 68 percent calcium hypochlorite should be used to make a 6% solution. He recommends 1 1/2 Tablespoons per cup of water. The military standard is 1 1/2 teaspoons per cup of water for a 5% stock solution.

Thanks for being part of the solution!
There's a big difference in your being wrong this one time vs. other TH-cam'rs, you guys get right out there and correct your mistakes as soon as you possibly can! Thank you for all you do!
It isn't one time. They've sold a book with the wrong information.
@@everythingmatters6308 And which one would that be and which information was incorrect?
Actually there previous recommendations for treating water is still valid and could do the job. Following the Military version and Jays are all good as well.
remember they still do not know either
Science and technology always improves over time… if we cannot learn by experience and understanding in a scientific manner, then we have wasted the notion of the scientific method.
Great video.
Food storage and pantry development continually needs improvement.
Excellent video. There's nothing more reassuring to me when it comes to trustworthy sources like someone who's not afraid of, not only admitting, but even volunteering when they've made a mistake. Thanks so much for this video.
This is much appreciated, thank you for providing the updated printable.
Thanks so much for the update. Printing everything! What a service you provide to us!❤️
🛠️🛠️Just a comment that has nothing to do with the video itself ... as the frame of your video is red and thin, it is easily confused with the bar that tells us listeners if we have already viewed the video. it would be a good idea to make your frame either wider, or another color.
Thank you for your content! 😊
And if I may make a wish: I'd like a video on cheaper alternatives to Berkey filters.
All good points and previous and updated recommendations would all work. I've always gone with the Military recommendation and increased it slightly if it was dirty or unclear water and as far as making A stock solution of it meaning getting a gallon jug and adding a cup in a half of the chloride hypochlorite and making a jug to add to laundry that is the right abt Jay came up with. BUT folks newbies don't get confused and think for every gallon of water you need to add 1 1\2 cup to purify it for drinking water that's why they said its a stock solution not for drinking, for every one gallon of dirty water you want to purify follow the number of drops on the chart to add to one gallon of future drinking water which is 8 drops for clear or 15 drops for unclear water needing to be purified. I've seen people actually get confused over instructions for making bleach stock solutions verses instruction just for purifying water unfortunately. GREAT video and good points, such as Chloride hypochlorite is Dangerous, if your a newbie please be aware it can be found in a very fine granular form BUT also in a very dusty fine form PLEASE get the granular form and where a mask when dealing with is. We have dealt with chemical aspiration cases over the years and can do real harm to your lungs. Also another good point do not store this stuff in metal OR OR even if stored in plastic containers or bags do not store near your metal water filtration systems in the same tot if your water filtration system uses a metal reservoir as this stuff will find away and will destroy over time your metal. Super video as always and thank you for your time and efforts in these things.
Perfect. Thank you very much. A lot of preppers when talking about drops don’t take into account. That’s small bottles have small droppers and most of the bottles have a regular size dropper but people may not be aware that a drop does not equal a drop dropper size may differ. Thank you.
Excellent tutorial. Thank you Jonathan and Kylene. Happy trails!
I'm with your wife. I'd rather have dozens of small bottles of water. Though I'm thinking more on the lines of a water purifier and then heating it to full boil for 2 to 3 minutes. Let it cool in bottles with lids on it so to keep it cleaner and more likely to be and stay that way.
It would be good to have a mixing table for a variety of things. In shtf there will be a lot of uses for chlorine solution. For people with a gravity septic system, they can still use their toilets. They simply have to fill the tank from buckets. Well, the toilets still could use cleaning. In fact in shtf it will be much harder to maintain hygiene so having a chlorine solution available will be very necessary.
Next, in regards to drinking water disinfected with chlorine. Remember, water that sits overnight loses a lot of the chlorine. This means you want to create a system. You need to use water from an open container that has sat some time and while you are using that container you have a separate container that is sitting to off-gas the chlorine. You just keep swapping back and forth with use from one and have the other off-gassing.
one of the best explanations out there, great job
We get frequent hurricanes where I live. This is very useful information. Thanks!
Thanks for this update and Jay's document. 😊
Could you please share how to pasteurize with a sun oven? Or direct me to a video that you've done? Thank you.
Look at this video about 4:26 th-cam.com/video/MPLduMim7VY/w-d-xo.html
I am so thankful for the both of you. I have been using your calculations given for the bleach solution. The one you guys suggested at the 5% military is quite strong enough. The 6% is 3x more calcium hypochlorite. When I made it, seems overkill.
Yes! I'm looking for a deal and now 65% is far easier to acquire than 68%.
Thank you so much for this information! You put in a ton of work and I am grateful. Peace and blessings to you both!
Thank you so much for joining us!
This odd duck useful information. Thanks for all you do!
Thank you for this update. I purchased some calcium hypochlorite a couple of months ago and plan to use it in my water program.
I’m confused. And scared. Can I just boil water for drinking? 🇺🇸
Thanks for the update - much appreciated. I always tell people to watch your videos for great learning.
I appreciate that!
Thank you for the printable label. It's exactly what I was planning on making.
Thanks for the update!
Great info, guys!
Thanks for this important update!
Thanks so much for this info! New, updated pages going into my emergency binder….
thanks for the info / i have 2 / 250 gal tanks i have just ruffly figured that one gal of bleach would do the job per tank but we just use it for washing and pet water but unsure what the small creek sends down to us / we drink bottled water and boil the creek water if we use it for cooking
Great informative video. Would you please confirm the following calculation for me: I currently have a 275 gal IBC tote container for storing emergency drinking water. My 275 gal IBC tote will be filled using readily available city tap water. According to Jay Whimpey's calculations, I would need 2.5 level teaspoons of dry powder DryTec 68% Calcium Hypochlorite to disinfect and preserve this 275 gal container of city water. Is this correct? Also, do you have a recommendation on how long I can safely store 275 gal of purified drinking water before changing it out? I would greatly appreciate your feedback. Many thanks!
Hey, I wanted to give you a heads up that there may be some issues with Jay's paper on water treating that you link to here. I was going through it and towards the bottom it notes that 4/10 of a cup of shock powder goes into a gallon of water (minus one cup) for creating bleach. But then later notes that a ratio of 1/3 of a cup should be used for a quart of water. So it's 4/10ths for a whole gallon and about 3/10ths for 1/4 of a gallon (a quart). Those are two different ratios. I just wanted to give you a heads up on that. There may be other typos as well. It's an important topic, and especially since this video was a correction video on a previous one, I thought you'd want to know about it.
Thanks
Thanks for the update. That really helps.
One other thing- much is based on a drop (from a dropper). There are various size droppers relatively sized for the small bottle they come with. Can you indicate the most appropriate dropper size so things remain consistent with your information. Thank you
Droppers that have markings should be calibrated to a standard. 1 mL = 20 drops. Approx 5 mL (4.99) in a teaspoon 😊. Hope this helps!
Thanks for the info ! Hopefully this is the correct amount I will do more research as you suggest! Thanks again
Can cistern water, that has been collected from gutters attached to the house be treated with this? Bird feces is a problem in the water because they sit on the roof
Very good information. As stated so well, this stuff is very dangerous and should be respected. Storing in large containers greatly increases the risk should the jar be broken. A good option might be the 1/2 Pint Mason Jelly Jar w/ Mason Plastic Lid. The small jar is less likely to shatter should it be dropped. Keeping the 'stored jars' in a secondary (plastic) container should be considered as well.
Thank you for sharing this information it is good to know. And i can recommend to buy activated carbon powder and the best is to buy the food graded activated carbon. Because you can use that for making DIY water filters and you can also use it for yourself as well. And the other thing you can use for water purification and clean wounds is potassium permanganate and you can also use that for signaling as well.
I appreciate you guys so much. Great job on updating us🤩
I also bought me a Brookie water filter from Walmart came with the filters also really like it looking to buy more also looking at maybe looking for more way of of doing my water
Thanks!
You should look into uv light disinfection...
Small aquarium lights can be had for about 20 bucks.
Great video instalment!!! Thanks so much 🙏
Absolutely wonderful video with germane info. Thank you, both, very much
By the way I sent you guys an email months ago on your website about this very thing on measurements and I never got a replied...do you guys check your website emails?
I think ill just skip that... and boil and filter my water... I also have a couple of Berkeys and a Itehil system
Having issues with downloading your doc using Safari and Google browsers. I ca print your label and the other guys paper on purification but not your. Don’t think it he issue is me.
PS love the channel!
Even if you boil your water you still have to filter it because of cysts on the water
I put the original bag of pool shock in my laundry room cupboard and in less than 6 months it had corroded my cupboard door hinges to the point of being totally rusty! This stuff is HORRIBLE! I have another bag somewhere but don't recall where I put it. Who knows what will be destroyed before I find it? AKH!
Many thanks
I do wilderness hiking and climbing and only use water filters with zero boiling and zero chlorine or iodine. I’m wondering your thoughts on only filtering for water purification.
How about just using aqua tabs?
I reside in the state of Michigan, and it looks like there is a restriction on 68 percent calcium hypochlorite. The only thing I can find on retail shelves is 57 percent calcium hypochlorite. These formulas would be of no use here in Michigan unless there is some way to recalibrate the formulas.
It's funny because us swimming pool people have buckets and buckets of that in our garage. Just sitting there never have been given it a thought that it's even that dangerous
Hey guys! What about the common pool supply store 73% calcium hypocloride?
In addition to pool shock I can distyl, filter, purify, RO, and even make water from air.
Is there a way to test the effectiveness of any chlorine treatment? A decent and reliable home based testing system?
You can get test strips for chlorine levels which relates to effectiveness. But to test effectiveness directly you need lab equipment and a microscope.
Thank you for this information. Do you have any information on what happens to water if it is pressure canned? I would thin because the internal temp goes up to 240 degrees it would kill off some things but what about viruses that might be in water?
I have one extra step, after disinfecting with calcium hypochlorite I add equal parts iodine about 30 minutes before drinking (at least 1 hour after chlorinating). That gets rid of the chlorine flavor, which can be unnerving to consume.
Hmmm - your ChE assumes a consistent bulk density (different from compound density) in all sources of powder available to all your listeners. How about biting the bullet and weighing the powder or putting a big enough fudge factor in the volume measurement. -- Logan, ChE
Also keep in mind that any chlorine products can have a very violent reaction with any petroleum products. Potentially spontaneously starting a fire.
Hi how much pool shock to a galloon of water please thanks 👍🙏💖🇬🇧
so we do not use pool shock anymore and just use your system?? I'll go to rosered for this type of advice she is a chemist PHD
I had to look it up because without a pint measurement I got confused.
please could you tell the quantity for 55 gallons water
cook all your food in a 15# pressure cooker too
Hi there I have a question...as you know once its made the chlorine dissipates ...so how long would a 5% bleach solution remain effective once you have made it.❤
Simply make your own CLO2. Cheap & effective.
Does one packet fit in a standard pint jar ok with room to gently roll the powder to mix? And size mylar bag- 7mm or 5mm?
Store Cal Hypo in a glass container with a snug fitting plastic lid. The fumes are very corrosive to any metals. Even the plastic bags or pouches that Cal Hypo often comes in, eventually disintegrate. I would NOT recommend storing the powder in mylar bags. Although Mylar bags are made with polyester film (BoPET) a thin layer of aluminum is vapor bonded into the polyester to provide a barrier against light and moisture.
Are you SURE about the math here? Jay recommends 3X the amount of Hypochlorite to go from 5% to 6% that seems extremely high. I don't want to get anyone sick.
Do you recommend filtering the water before or after using the calcium hypochlorite solution through the charcoal filter.
Jon says before but I say after. I want to run my chlorinated water through a charcoal filter to get rid of the chlorine. He wants more stuff removed before.
So are you saying we need to filter AND boil or filter AND disinfect? We use Sawyer mini (.1 micron level filter I believe) and my children love to drink out of the creek or lake with just their sawyer mini. Should i also be doing another step?
Your best defense is to filter AND disinfect. A good .1 micron filter will remove all the critters, but not the viruses (0.005 microns). Chlorination kills viruses, but doesn't touch crypto and is only somewhat effective against Giardia. If you filter and disinfect, you cover all the bases.
If you boil (or use UV light) you do not need to disinfect. Either treatment will make the water safe to drink. However, boiling large amounts of water is impractical and takes a lot of fuel, so may not be the best method to rely on during hard times.
What is the proper steps, Filtration then disinfect, or disinfect then filter?
Your choice. Jonathan and I disagree about this one. I like to disinfect first and then filter to remove all of the chlorine and junk. Jon wants to filter first because he feels that the chlorine can work better without all the critters in the water. I'm sure there is a "right" way but I clarify, disinfect and then filter.
Jay Whimpey and Jim Phillips (another expert) recommended filtering before disinfecting. Pathogens hidden inside tiny particules could potentionally survive the chlorination step. Filter out the particles and the critters have nowhere to hide. Of course, you could certainly do a final filtration through charcoal filters to remove the chlorine before drinking.
How to we fix or gallon after making it the old way
I am unable to find pool shock at 68%. I tried the link listed for the pool shock and it too is listed at 65%
At 2:20 - How many sun ovens will I need to provide enough water for a family of 4 in E TN? And if you calculate based on 4 gal/day you automatically fail.
Ok. One, I'm glad about the smaller bottles. That would be us. I have a question. You said you rotate the pool shock(?) to disinfect your laundry. Is this like those lysol laundry disinfectants? Will it bleach my laundry? Info on that would be great. (Unless I missed it. Lol) I would rather rotate my shock than buy/use the laundry disinfectant. Or use to disinfect during cold season on countertops and fabrics. Thanks for the video.
Fyi: I have not been able to find pool shock with more than 50 something %. Do you get yours on Amazon?
Does anyone know if it's possible to successfully store purified water(non- chlorinated) in mylar bags?
ALSO
THERE IS AN EFFECTIVE DIFFERENCE BETWEEN CALCIUM HYPO AND SODIUM HYPO...... BEWARE
I wish I could save your videos. A lot of good info here.
6 quart pressure cooker from target or walmart is very inexpensive ( realy cheap ) . get the one that uses weights
The one I found is 99% pure and comes sealed in little plastic bottles, from some chemical supplies co. I wonder if the same amount is needed.
99% Cal hypo is a significantly stronger concentration, so I would think you would use less (the original military formula). If you used the new formula with 99% Cal Hypo, it would make a stronger solution and you don't want to drink overly chlorinated water.
I thought the reason for the adjustment was because people are using a lower concentrations of Cal Hypo (in the 68% range). 1 teaspoon of 99% is going to provide 50% more Cal Hypo than 1 teaspoon of 68%. If someone is using the weaker 68% Cal Hypo, they should use the new formula (more powder to get the same result).
I have to boil water
Interesting. I made a solution with 1.5 tsp of the recommended pool shock in 1 cup of water. I did some tests with dilutions and chlorine test strips and it seemed to be a little over 6% in my tests. Also, my pool shock doesn't fully dissolve at this concentration. Is this normal?
I don't think their measurements are correct. Pam, who has a PhD and is a scientist at RoseRed Homestead, has a video on Calcium Hypochlorite. Her base solution is 1/8 of a teaspoon to 1 pint of water, which will sanitize 12.5 gallons of water. I love the Provident Prepper, but you should go to Rosered Homestead to watch Water2: Filtering and Sanitizing Emergency Water. I made my base solution precisely as she said and had no problem dissolving it.
1/16 of a teaspoon to 1 pint, not 1/8. Look in the description
@@jenniferkelly8728 RoseRed may have a PHD but has no common sense. Scientist? Really? Grade school teacher more like it. Granted I have only watched 2 of her videos but she made potentially deadly comments in both so I blocked her. She knows just enough to be dangerous. IMHO.
Iodine!!!!
Now you have made to scared to use this stuff.
boil 10 min or use a life straw. my plan anyway.
Have you tried using a life straw? I find it very difficult to suck hard enough to get enough water after just a few minutes. It also puts my face very close to contaminated water.
@@TheProvidentPrepper I always wonder why people don't scoop water into a water bottle then put their Lifestraw into that. So easy to carry an empty container for that purpose. Why drink like an animal? Scoop out some water then use your straw filter...
video could have been streamlined to make it shorter and less confusing
To me it's useless to sterilize just a cup of water.
Its to make a cup of 5-6% bleach which treats gallons of water.
Ah cmon,-212... For how Long boil!?
I think boiling time and temp are relative to your altitude. Google might have that info.
Its just gotta get past 165 for several minutes. If it gets all the way to boiling you're done.
DO NOT USE HOUSE HOLD BLEACH to disinfect water. They have surfactants in it (soap) AND POSSIBLY FRAGRANCE. This is to help it clean. If you are going to use bleach(sodium hypochlorite) use a pool grade bleach as this is what it is for to disinfect the water in the pool. Clorox would probably be ok in a pinch but I would not go out and buy it for this purpose!
Read their book. They recommend plain bleach with no additives or fragrances.
@@steveb855 like I said don't use regular household bleach. It has surfactants in it to help the bleach clean clothes etc! It's designed to clean not treat water like pool bleach
Pool shock is very dangerous and should not be messed around with by non professionals. It on the same danger level as leaving a container of lye laying around like it’s just another cleaner. My sister jumped in a pool for mere seconds that was being shocked and it made her deaf in one ear. Please do not encourage people to handle commercial chemicals in the name of prepping (which is preparing for the possibility of a break down or sociaty) I’ve been prepping for 20 plus years. I would never store or load up on caustic chemicals long turn. You can’t rotate them... Be reasonably, responsible and protect your followers.
Millions of home owners manage their own pool chemicals. You could alway move to Oregon and have somebody pump your gas for you to be 'safe'.
please just let Jay do the talking about this subject. You only very much confuse this ISSUE which is vitality important to so many. You talk I do not listen.
Thanks
Thanks for the update!
