Oopsies, I Forgot Saltwater!!

Last night as I slipped off to sleep, it occurred to me... I didn't discuss desalination at all.

It's kind of mind blowing when you consider the number of people who've never seen an ocean, yet only 1% of the earth's water is liquid freshwater. 97% is salt water and we can't drink it without removing that salt. To be quite honest I've lived on the West Coast pretty much all of my life. I spent most of the first 20 years just five minutes off the beach. That said, desalination is not something I would ever consider for my survival situation, unless I was on a boat stuck out at sea, not long-term anyway.

Personal filters life Lifestraw, Survivor Filter, and Sawyer do not remove salt. The big boys, Berkey and such, do not remove salt.
In my previous article, we discussed a few different ways to distill water. Solar distillation will remove salt, as well the various types of fire-heated (or propane, or whatever) distillation methods. The main issue with these is that they take time, so they aren't super convenient.

You can distill water using reverse osmosis, but I honestly, only know how to do this with raisins and have no clue how you would do this on a large scale.
There are units you can buy, mostly marketed for boats I think, but these have motors and require electricity and just don't seem incredibly feasible for the majority of the population.

If you're in a coastal region, it would be wise to really understand what brackish water is and how to avoid getting sick. Brackish waters are estuaries, swamps, rivers, etc, where fresh water meets saltwater. While the water may not taste overly salty, it can still contain too much salt for your body to handle. This questionable region can actually vary quite considerably in distance, there is no golden rule of 300 feet or a mile. It's always best to look for a small running stream that runs into a larger body that meets the ocean, especially if you can see that it comes from a raised elevation. My part of the world, Oregon, it's easy to find this. I encourage you to study your region and figure out how to best read your local ecosystems.

While knowing how to distill saltwater is an incredibly useful tool to have in your back-pocket, it's certainly not what I want to use as my water source plan A, B, or C.

  1. I tend to agree with you on using distillation apparatus to purify water. There are so many methods when it comes to distillation, pot stills, reflux columns, coil units. I think people should have some means to distill, and know how to use it now, do not wait until an emergency to learn.

Hopefully, by this point, you've identified your key objectives. What trouble you can most likely expect and your best options to deal with it... even if only vaguely. Keep working on it. Refine & Rethink constantly, but while you do that let's talk... water. If you're thinking about short term survival issues, storing water is generally no big deal. The basic rule of thumb is 1 gallon/person/day, but keep in mind you might have a lot of add water foods.... and bathing or washing dishes. **Don't forget your pets.** It might be more realistic to consider 2 or 3 gallons per day. You can buy various kinds of bottled, canned, or bagged water. You can "can" your own water in mason jars. You can fill soda and Gatorade-type bottles. You can buy big reusable water jugs (they usually store 5 or 7 gallons). You can get the big bathtub water bags and hope you have time to fill it before disaster strikes. You can get barrels or big water tanks. There are many, man...

3 Hours Without Shelter

3 minutes without air   3 hours without shelter   3 days without water   3 weeks without food I think it's obvious by the way I've presented these articles that I place water above shelter. That said, it's still pretty damn important. When I think of this topic, I think of tarps, tents, debris huts, R-Pods, isolated cabins in the woods, but I realized something else when I considered why it was "3 hours" category. You don't necessarily need shelter so soon if you have a decent jacket or clothing... *facepalm*  Shelter is not just a place to sleep. Shelter means protection from the elements; jackets, rain ponchos, maybe even sunblock, as well as a place to call home (even if only for the night). So don't overlook these things, having a proper outer-layer makes a huge difference when considering what kind of shelter you need. In this same category of shelter comes sleeping bags. These can be really damn expensive, but for the most part, you get...
