The Monday SHTF Thread


Water is the most important resource for survival. At least 60% of the adult body is made of it and every living cell in the body needs it to keep functioning. Water acts as a lubricant for our joints, regulates our body temperature through sweating and respiration, and helps to flush waste.

The maximum time an individual can go without water is maybe a week — an estimate that would certainly be shorter in difficult conditions, like the normal summer heat in the south. Having water, and having the ability to purify water is paramount to your preparations.

You’ve probably heard about the “LifeStraw” as a way to be able to use contaminated water as a source of drinking water. This Lifestraw “non-review” is by IamZeke at Survivalist Boards should open some eyes:

LifeStraw was created with a specific purpose and that was to filter drinking water to remove biological pathogens in remote rural 3rd world locations. For its original intent it is a decent product. But most of us have access to numerous product options and most of us live in 1st world locations where found ground water is typically contaminated with organic toxins. Pesticides, herbicides, fertilizers, petrochemicals, industrial runoff, and post-consumer runoff are all easily found in open ground water around and downstream of modern civilization. Even rurally you can can find a lot of this stuff. The LifeStraw does absolutely nothing to mitigate this issue. Whereas biological threats are a hit and miss these toxins are everywhere. LifeStraw by physical design does not connect to other products, so any attempt to add toxin removal with be a lash-up DIY affair of dubious effectiveness.

Furthermore, the LifeStraw lifespan is highly dependent on the purity of the water. Sediment rapidly shortens its lifespan and it has no method to backflush it effectively. The Sawyer line has a much longer lifespan and recognizes the need to backflush. It is purpose built to enable that necessary function. That brand is also built to connect to other devices which gives you the option to filter toxins. The Sawyer Mini model is now costing barely more than the LifeStraw.

Of course, some of you like the portability and “completeness” of a straw system. Fact is that LifeStraw is in the minority when it comes to straw systems in regards to toxin control. You will need to do your research on price and confidence, but you can get multi-stage straw systems that filter both biological threats and toxins from these companies: Aquamira; H2O Survival Straw, NDUR, Aquagear, Diercon, and Seychelles. I’m personally a fan of the Seychelles because I like their upfront nature about their testing and their variety of straw options, but any of these brands offers toxin removal that LifeStraw does not even make an attempt at.

So, buy the LifeStraw, or do some research like IamZeke.

Nice work, dude.

Second, is a pdf that I received from a fellow Mississippian. How do you use pool shock to make normal household bleach, and then purify water? This explains the process pretty well
