Solar Water Disinfection and Pasteurization, by Ariel

This article describes so me simple and practical methods for providing drinkable water in disaster situations. They fit with my motto: “Keep calm, and carry on!” According to the EPA, if you can’t boil water, you can disinfect it using household bleach. Do not use non-chlorine bleach to disinfect water. Typically, [when freshly-purchased] household chlorine bleaches will be 5.25% available chlorine. Bleach will kill some, but not all, types of disease-causing organisms that may be in the water. If the water is cloudy, filter it through clean cloths or allow it to settle, and draw off the clear water for …


Letter Re: Lessons from the January Ice Storm

Jim: The Ice Storm that just plastered Kentucky brought some reminders of just how bad things can get and how being prepared – in advance – is critical. Within a few hours, everything became coated with a half-inch to an inch of ice: roads, cars, trees, power lines – everything. Throughout the night, we heard crashes as our neighbor’s trees lost massive limbs. We knew it was only a matter of time before trees limbs (which are not properly trimmed back by our utility company in an attempt to cut costs) collapsed on power lines and caused widespread outages. In …


Letter Re: Colonial New England Community Blockhouses as a Historic Precedent

Hello Jim, Mosby’s description of defense tactics was common all along the frontier in the 18th Century including western Pennsylvania. As defense against indian raids, a small blockhouse was built on a farm in a central location. A spring [or shallow well] for water was a necessity. When news of local raids spread, people would gather as many possessions as possible and head to the blockhouse for the common defense. This is an instance where much can be learned from history. While these small forts where rarely overrun, the abandoned farms were wide open to burning and pillage. Destruction of …


Hurricane Lessons Learned and Some Advice on Getting Prepared, by Ken on the Gulf Coast

Sometimes it is not an option to relocate so you have to get prepared wherever you are located. I am located on the Gulf Coast 60 short miles from New Orleans, Louisiana. We were ground zero for Hurricane Katrina, so I have a first hand experience of what can happen I will describe some things that I did right and some things that I did wrong. We were unable to relocate to a place like Idaho as we had elderly parents who could not and probably would not relocate to a more appropriate survival area. My mother was born in …


Field Gear on a Shoestring Budget: Ten Project Examples, by George S.

The following are some hopefully useful field expedients, substitutes and spares, all of which can be had for a buck to about ten bucks each: #1: Drywall Saw: if you don’t have one of those all-purpose $49.95 survival knives or field shovels from Gerber or Glock with the accessory root saw, or you’ve found that the finger-length saw blade on a Swiss Army folder leaves a lot to be desired when cutting a 2×6 [board] down to size? A bow saw or flexible survival kit saw are a couple of possible candidates that may be up to the task, but …


Letter Re: Precipitation and Growing Season as Retreat Locale Criteria

Sir, Regarding your Retreat Areas recommendations: I grew up on a small multi-crop and livestock farm in north western Iowa, with 24 inches of precipitation and 180 frost free days. I have been living in California Eastern Sierra since 1982 , but soon will be leaving. I respectfully submit that your assessment of the agricultural capability of many of the low precipitation/low humidity areas of the western US is vastly overestimated. Western states such as Nevada, Utah, Arizona, and New Mexico are not farmable by amateurs using conventional means available during any TEOTWAWKI scenario. Obtaining water rights and controlling large …


Letter Re: Small Volume Water Purification with UV from Sunlight

Jim, I recently learned about a water purification system that is being promoted by Rotary International for Third World areas without safe drinking water. Simply put: fill a plastic bottle with water, and leave it in the bright sun for six hours. The ultraviolet (UV) light kills the pathogens, and the water is safe to drink. [JWR Adds: This method only works well with fairly clear water. UV light cannot penetrate very murky water, and it will not sterilize any plant matter suspended in the water. So be sure to use a pre-filter when treating water from open sources such …


Letter Re: Seeking Advice on Assembling Web Gear

I love the questions on web gear. Best advice I can give, having gone through multiple iterations of trying this and that, is to divide up your load. What do I mean by this? In the military they have a “combat load” and an “approach load” concept. Your “combat load” is the web gear that you see troops with all the time – their “battle rattle.” On the other hand the “approach load” is similar to what we would refer to as a survival load (roughly). The major problem with web gear is that it does not work with any …


Letter Re: Seeking Advice on Rainwater Catchment and Filtration

Sir: I am an environmental engineer. You posted a letter that inquired as to whether a ceramic water filter was capable of removing chemicals that leach from plastic containers. The answer is no, a ceramic microfilter will not remove the chemicals. Aside from reverse osmosis, which requires pressures that are too high [for treating large volumes of water] in a survival situation, the best choice for treating water with chemical contaminants is to use activated carbon. Activated carbon is very cheap, widely used by municipal water treatment plants, and is highly effective at removing many organic contaminants (through adsorption). I …


Two Letters Re: A Vehicular BoB

Mr. Editor: I have been a reader of this blog for a little while now and one of the earlier postings I read caught my eye: In regards to a vehicle “bug out” kit. That list was certainly a good place to start, but it was missing a few items, so I thought I would put my “two cents” worth in. To give you a little bit of background, I would describe myself as essentially being a realist. I watch the news, I read the papers. I know what is going on around me. I am aware of today’s political …


Letter Re: A Vehicular Bug-Out Kit

One thing that I have not seen properly addressed anywhere online is an appropriate kit for the bug out vehicle. You folks in snow country can reply to this with some recommendations for that scenario. Please do. I survived five hurricanes , one of them in the Virgin Islands, over the years so I consider myself an advanced student of the Bug Out Vehicle. First and foremost. Cars are useless without fuel. They make a decent shelter but they’re tough to carry with you. I haven’t seen a backpack that would hold one. Get yourself as many large cans as …


Letter Re: Seeking Advice on Rainwater Catchment and Filtration

Mr. Rawles: When constructing a rain-catch such as this one, which the good folks at Lowe’s [–a major hardware store chain in the US–] suggest for economically watering your garden, is there any instance where it would be okay to use this as a backup for drinking water? Obviously, one would be foolish to drink directly from containers that are not food-grade or if the water has been sitting for too long a time. But, my question is does that change if you plan on running the water through a purifying process such as through a Berky or this economically …


Letter Re: A Suggested Checklist for Preparedness Newbies

Here’s a beginner’s list I made for my [elderly] father today: Food {Brown pearl] rice does not store well. Neither does cooking oil so that needs to be fresh. No, Crisco doesn’t count. Coconut oil would be your best bet. Wheat berries – 400 pounds – bulk order at your local health food store Beans – 400 pounds – bulk order at your local health food store Mylar bags Spices Salt Country Living grain mill propane tanks, small stove and hoses to connect freeze dried fruits, vegetables, eggs and meat if you can find them. Water 500 gallons of water …


Letter Re: Mexico as a Retreat Locale and Advice on Water Filters

Hello Folks, I just completed going through a portion of the SurvivalBlog archives and look forward to exploring the site further. I especially liked the animation about Libertarian philosophy. Very well done with excellent points to consider. I have recently returned to the US after having spent four years in a small village in Mexico outside of Guadalajara. I am an artist and teacher of art and semi-retied there after having had my medical insurance increased a number of times to the point of being ridiculous. I just got fed up and moved south. Two years earlier I had spent …


Letter Re: 11th Hour Preparations: It is Not Too Late to Start

Jim: It is not too late to prepare for the hard times that are coming. But time is short, so I am going to be brutally blunt. Prices are going up. If you don’t already expect double digit inflation, you haven’t been paying attention. If you are just realizing that you need to prepare for the future, forget buying barter goods. Forget precious metals to swap for what others may be willing to sell. The idea of buying things so that you can swap them for other goods or services later is bad policy. That’s right. I’m advocating that you …
