A Primer on UVC Light – Part 2, by Dr. David J.

(Continued from Part1.  This concludes the article.) Area Disinfection For area disinfection, an unshielded UVC light bulb is put on a lamp and controlled either by remote control or timer. Many are purpose-built, but it is certainly possible to buy a UVC bulb and place it on your own unshaded lamp and use a generic remote control or timer. The UVC rays will neutralize microorganisms in the air and all surfaces that the light strikes. It can also be used to disinfect strategically placed masks, clothing and other items. In my opinion, the strength of area UVC light is to …




A Primer on UVC Light – Part 1, by Dr. David J.

Whatever your take on COVID 19, it has certainly sharpened our focus on contagious disease. As we spiral downwards as a society, it’s a good bet that other contagious disease will be visiting us more often. It is important to remember COVID 19 has not made other diseases fade away, even if the media attention on this virus makes it seem that way. Preppers often focus on bullets, beans and bandages – weapons, stored foods and trauma-related first aid supplies, but realistically disease is probably the main killer in any long-term scenario. The purpose of this article then, is to …




Age-Adjusted Prepping, by Wandering Will

It is said that prepping is not a movement or a philosophy. It is a way of life, and a way of life must accommodate changes in life. Having squarely arrived into my “Golden Years,” I was reluctantly forced to take a fresh look at my prepping agenda. Not exactly a newbie to the game. I’m still eating Year 2000 Problem (Y2K) food, I have accumulated food, gear, and training over the years and have reached a somewhat reasonable level of comfort. However, we all know what happens when we start feeling confident. After a few recent practice drills and …




Water Treatment Options: How to Avoid Poisoning From Toxins- Part 2, by AJS

In part 1, we learned that toxins other than mercury cannot be avoided entirely in the drinking water, as some are not removed by screens, activated carbon or silver water filters, or chlorine treatment. Some toxins are even made more toxic by boiling. Furthermore, some toxins cause physical symptoms of poisoning almost immediately. In particular, populations of cyanobacteria (a blue-green algae) may be dominated by a single species or be composed of a variety of species, some of which may not be toxic and some which have been deadly to animals. We learned about the locations, timing, and durations of …




Water Treatment Options: How to Avoid Poisoning From Toxins- Part 1, by AJS

Long-term survivalists find themselves in many environmental settings, but the common denominator is often the desire to be close to fresh water. A person needs it to drink, cook, bathe, do laundry, perhaps wash prospecting finds, and even fish and swim in as recreation for family members. Dangers in Raw, Natural Ground Water In raw, natural ground water there are dangers. These include: chemicals, such as nitrogen and phosphorous from agricultural runoff, microorganisms feeding on pollution that can cause disease, heavy metals, such as mercury and arsenic, which have implications to human health, and toxins caused by algae. The survivalist …




Thirsty Are Those Who Do Not Prep- Part 5, by The Grumpy Gunfighter

Survival Water Filtration, Purification, and Disinfection Methods (continued) Without water, survival is impossible, even if you have a storage facility filled with bullets, bandaids, beans, and batteries. My family and I prep in the desert southwest and have taken action so that we won’t find ourselves thirsty in the event of a crisis. In parts 2 and 3 of this article series, I thoroughly covered both professional drilled and hand dug wells. But once you have access to the water, you need to be sure it is safe to drink. So, in Part 4, we began looking at methods for …




A Portable Water Distiller- Part 2, by JMD

Recent history has shown us that clean water is almost always one of the first items to become unavailable after a disaster. Since I live within a day’s walk of the Atlantic Ocean and occasionally camp near the shore, I wanted to make a portable water distiller that could handle salt water as well as some of the more contaminated fresh water sources. In this article, I outlined my objectives for a distiller and now am writing how I built one. So far, in part 1, I have provided a materials list and provided the first few steps, which included …




Letter Re: Storing Calcium Hypochlorite

Hugh, I was wondering if there was a better way of storing Calcium Hypochlorite? [POOLIFE TurboShock 78% Pool Shock 1 lb] Glass stopper bottles Would using a 1/2 gallon Ball [“Mason style”] jar and Tattler plastic lid be a workable alternative? I forgot to repackage some that I bought a couple of years ago. It was fine at the beginning of hurricane season, but isn’t anymore. Shame on me. I’m glad I stored it on a shelf by itself. How did the Tattler plastic lids on Mason jars do? Does it need to be vented annually? – T.J.




Letter: Water After Irma, by RV

HJL, It was 4 am and the flow of water from the tap conspicuously lacked vigor as I begin the tooth brushing process. We just had Hurricane Irma visit as a tropical storm. Many, including schools, are without power. My mind leaps to the conclusion that the water treatment plant is also out of power and I am in a real fix. No way I am filling my 50-gallon barrel on such a tentative flow. I curse the utility for not warning us that they could not process water. I also think, “Of course.” So I start thinking about hauling. …




Letter: Kitchen Water Filter Advice

Hi, I listened to JWR on yet another interview (making the rounds) and wanted to know if you (or Hugh) would be able to suggest a water filter I could use for my kitchen sink.  I live in an apartment. Management informed me that a Water-Filtration System (as in reverse osmosis) is not allowed. Is there anything, not super duper pricey, that I could attach to my faucet? Thanks! – T.N. HJL’s Comment: Many of our readers use a Berkey water filter. You can get these for under $300 from many of our advertisers. The advantage of the berkey type …




Understanding Water Filtration, by Old Soldier

The understanding of water filtration requires a look at various filtration methods as well as contaminants. Let’s take a look at these. Water Filtration Methods Carbon/Activated Carbon Filters Activated carbon chemically bonds with and removes some contaminants in water filtered through it. Carbon filters vary greatly in effectiveness. Some just remove chlorine and improve taste and odor, while others remove a wide range of contaminants, including asbestos, lead, mercury, and volatile organic compounds (VOCs). However, activated carbon cannot effectively remove common “inorganic” pollutants, such as arsenic, fluoride, hexavalent chromium, nitrate, and perchlorate. Generally, carbon filters come in two forms– carbon …




Water Contamination and Filtration 101, by MHN

*For those of us who prep, I am tailoring this guide to contaminants that would be found anywhere: radiation from fallout, chemical contamination from industry, contamination from urine and feces, natural sources that one might encounter on a homestead, and the technologies and techniques like filtration that would be most widely available in a SHTF scenario. I am an engineer who has specialized in water treatment in the chemical industry.

Most of us rely on clean tap or bottled water for everything from drinking to cooking to showering. We pay little attention to the process that takes raw water and transforms it into safe clean potable water. Once upon a time our ancestors drank right from streams and lakes. While the quality of this water was most likely better than the quality of water from most modern day surface sources, it was still contaminated with various pathogens and minerals. Even though our ancestors’ digestive tracks were heartier than ours, waterborne illnesses ranging from minor stomach bugs to cholera and dysentery took their tolls.

Many of us believe that a high quality particulate filter coupled with an activated carbon filter will make any source of water safe for human consumption. However, that isn’t necessarily true. Contaminants come in many shapes and sizes. In addition, different contaminates require different technologies and processes. Geography and human development determine where contaminants are found. Consequently, suburbia is not likely to contain agricultural chemicals. PCB’s (polychlorinated biphenyls) aren’t likely to be found rural locations. BTEX compounds (benzene, toluene, ethylbenzene, and xylene), found in both gasoline and diesel, can be found anywhere.




Two Letters: Contaminated Water in Corpus Christi, Texas

Mr. Rawles and Mr. Latimer, As you may have seen in the news, the city of Corpus Christi has, yet again, been the subject of contaminated water. Over the last ~18 months, Corpus Christi has had a series of problems (five or six water boil notices, no drink advisory, et cetera) with the municipal water supply related to E.coli, low chlorine, high chlorine, and most recently chemical contamination Indulin AA-86 Asphalt Emulsion. I began reading/following the SurvivalBlog several years ago and at a minimum keep a “go box” action packer for hurricane evacuations, et cetera. I have a small amount …




Do-It-Yourself Ceramic Water Filter, by The Architect

Years ago, while visiting the South American country of Peru, I was stunned to find that every drop of drinking water had to first be boiled, before it was considered safe to drink. In a country of 22 million people, I thought this an incredible waste of money and natural resources. There had to be a better way. On my return, I set out to design a cheap ceramic filter that could be easily constructed using simple components readily obtained from any hardware or box store. (As a side note, on one of my trips to Peru, I was a …




Letter Re: Water Storage Options for Suburbanites

Hi, I was reading SurvivalBlog’s special page with info for newbies and I realized we are behind the eight ball. But my husband and I are Christians and we are both over 50. I am on disability but I am a retired Registered Nurse and I also sew, crochet etc. You mentioned that we needed to have an underground water tank and I don’t see that as possible for us, however we do have a pool just off the back deck. Any advice?  Thanks, – Carol C. JWR Replies: My mentions of underground water storage tanks were intended for people …
