Letter Re: Calcium Hypochlorite

I recently bought a 1 lb. bag of DryTec calcium hypchlorite through Amazon. When I repackaged it for long-term storage I noticed there was very little chlorine odor. I made a 1/2 gal. per directions for stock. I poured the stock directly on the tail of a non-colorfast shirt (bright red that already had white spots from a sodium hyphochlorite spill) and left it for hours; it didn’t even lighten the color. I don’t know any other way to test the amount of available chlorine that I have on hand, but I am deeply concerned that a lot of people …


Letter Re: Air Lift Pumps

Using compressed air to lift water from a well does work as described in the previous article; however, one must insure the compressed air comes from an oil-free compressor. If the air compressor has an oil-filled crankcase, the delivered air will have oil vapor/oil mist in it, which is not something one should have suspended in their drinking water. Do not trust an oil/water separator on the compressed air unit to remove oil vapors; they will eventually saturate and become pretty much useless. To confirm what your compressor is doing, check the condensate drain on the air tank. If it …


Letter: Disinfecting Drinking Water

Hi, Your articles have mentioned calcium hypochlorite. I went to the pool store today, and they had sodium dichloride. Should I ask specifically for the first? I’m not sure if the girl behind the counter is going to know how to help me on this one. Thanks – D. HJL Responds: We only recommend calcium hypochlorite, even though sodium dichloride is also used as a disinfecting agent. The pool shop should be able to order it for you. You are basically looking for a chlorine bleach solution to stabilize and disinfect your water. Liquid bleach has a very short shelf …


Letter Re: Well Pumps

Hugh, Regarding the recent information about well hand pumps on the blog (Simple Pump, Bison Pump), I would like to add that there is another robust and reliable pump that has not gotten the attention of many people outside of the farm & ranch community. It is the Model 11HD (for deeper wells) pump made by Baker Monitor. This pump is heavy duty (cast iron) with a design that has been around for almost a hundred years. This is the same type of pump that has been reliably attached to windmills on farms since its creation and has also been …


Letter Re: Waterwise Distiller

Hugh and Jim, Regarding the recent post on drinking water without a filter from ‘The Daily Sheeple’: I am sure you are aware, but your readers may not be, but distilled water is not something you would want to consistently consume. It will rob your bones of minerals and you will break apart. o o o Hugh, You linked to the water distillation video on The Daily Sheeple that featured the Waterwise distiller. I purchased one of those distillers and subsequently sold it, as I was not satisfied with it for a number of reasons. The water produced had a …


Systematic Efforts by the U.S. Forest Service to Take Control of Private Water Rights, by W.W.

Jamal Utah I am writing today to inform the readers of this blog about systematic efforts by the U.S. Forest Service (“F.S.”) to take control of private water rights. Recently, this blog made mention of efforts to institute the “public trust doctrine” in California. In Colorado, we have been fighting ballot initiatives concerning the public trust doctrine for years. While the public trust doctrine issue is increasingly concerning, I am writing today about what I feel is a potentially even greater threat to private water rights. In the last few years the U.S. Forest Service has been quietly revising its …


Two Letters Re: Toledo Water Crisis

Hugh, The WHO article you mentioned says there’s another way to purify water tainted with microcystins, and it’s one of my favorite water purification methods because it can also be used as a wound cleanse, an antiseptic solution, an anti-fungal treatment for the hands and feet, a cholera disinfectant, a treatment for canker sores, a fire starter, and even a snow marker for an emergency signal. On top of all that, it’s less expensive per pound than calcium hypochlorite. What is this wonder chemical? Potassium Permanganate (KMNO4) 98% 1lbPotassium Permanganate, also called “permanganate of potash” or “Condy’s crystals.” Read more …


Letter: Toledo Water Crisis

Hugh: I live in Toledo and was part of the recent “water crisis”. From what I understand, a Berkey, Lifestraw, or any kind of water pills cannot get rid of “mitocystin”, which was what was in our water. So, we had plenty of “water”, but no way to make it drinkable. I was wondering if your readers: agree that these won’t work on mitocystin have any alternative method of purifying water with this in it. – B.J. Hugh Replies: This is not something that I have knowingly dealt with, so I had to do a little research to come up …


Letter Re: Disinfecting Your Drinking Water

2

Hugh, I have noticed over the years that when I read about water purification during bad times that Calcium Hypochlorite is mentioned as the way to go for storage and use. Typically, it is suggested to buy an abundance of the material so one can be charitable and pass out small plastic bags of the chemical with instructions for its use to purify water. I’ve never before seen simple and concise instructions that ANYONE could understand for treating drinking water with Calcium Hypochlorite. Using what I’ve gleaned from the Internet, with numerous revisions, I believe I have the information that …


Letter: SHTF Water-Related Questions

Jim I keep hundreds of coffee filters at my house and quite a few in the BOB to extend the life of the Katadyn ceramic water filter when it comes down to that. Could a reusable gold-screen coffee filter basket be deployed to pre-filter water in a survival situation (with possibly other applications I’m not thinking of yet)? I have one I no longer use but nothing goes in the BOB unless it will serve well. My wife tolerates a giant stash of coffee filters because I use them every day, but she is less tolerant of salt accumulation, whether …


Letter Re: Gravity Fed Water Systems

Editor, A good and useful post by J.S. I always appreciate articles by those who have lived and used what they are proposing. As an irrigation contractor I built and used a homemade water system for a couple of decades in the Colorado mountains and can offer a few further ideas. For an infiltration gallery, I dug a small trench under the spring/small stream I had on the property and placed in the bottom 10′ of 4″ perforated flexible plastic drain pipe that came with a mesh “sock” around it. This pipe is used in French darins and the like. …


Gravity Fed Water Systems, by J.S.

8

Gravity systems are simple but very complex at the same time. Having lived on spring water that was fed by gravity for over 50 years, I have some experience in making these systems work and easy to maintain. I hope that my simple overview will help you design, build, and enjoy a gravity-fed system, too. There are four basic elements to a gravity water system: source, intake, sediment removal, and storage. Of course, you may have to deal with some troubleshooting down the road as well. Source The source can be any supply of free water. Spring, creeks, lakes, rivers …


Letter Re: The Water Solution

I liked the article and the follow up comments noting the sanitary issue raised. My plan is to drill a hole in the bottom of the right side of the water closet tank and put a separate filler valve supplied by water from the catchment system via a separate pipe. I have an abrasive edged hole saw and am about to go test it out on some decommissioned 5-gallon flushers. It’ll be interesting to see if I can successfully drill porcelain. I think this solves the sanitary issues of hooking up a catchment supplied system in a useful way, saving …


The Water Solution, by E.G.

I am writing this article because most of my friends are still living in major U.S. cities and I feel that this information could be very valuable to them. In a grid down situation, one of the most important items to have on hand is a quantity of stored water. According to the Rule of 3’s, in an extreme situation, you cannot survive three minutes without air, three hours without shelter, three days without water, and three weeks without food. I went off grid in October of last year, and I have learned a lot. I live on top of …


Letter Re: Clorox Changed Formula

Dear Hugh, It is the “splashless bleach” that is to blame. It is not sodium hypochlorite 8.25%, and if you look on the label you can see that it has a different active ingredient. Look for a “non-splashless” formula. The last one I bought a couple of months ago did say “Concentrated,” Clorox,” and “Regular” on the label. It whitens my sink like you wouldn’t believe! – Pat o o o Hugh, Regarding your questions about Clorox bleach, according to my Registered Sanitarian/microbiologist wife, for disinfecting Clorox Regular brand is the best. Avoid scented and splash proof products; they are …
