I love to check out survivalist sites- Blogs, forums, info pages, etc. You can find a lot of good how-to stuff that will help you be more self sufficient, independent of the corrupt system, and really do some Cheap-Ass-Living! However You need to take a lot of this crap with a grain of salt.
Take for instance the subject of water. You can go to damn near any "survivalist" site and find information about the subject. But most of the time the information is a bit silly. They will to go to no ends to tell you how to "store" water for a shtf situation but hardly ever tell you how to make the stuff safe to drink. You don't need to know how to store something that covers 70 percent of the earths surface. Hell, get some containers and fill em up, problem solved!
Telling you how to store water is nearly as ridiculous as telling you how to store dirt!
Now for the sake of the discussion I will concede that storing a "little" H20 for hard times is important. And I will also concede the fact that some sites devoted mostly to primitive living and wilderness survival has a lot of good info about rendering water safe to drink.
But if You really want the low- down about drinking water for a shtf situation then just use your common since. Make sure that it's clear and there's no strong smell to it. Boiling your water a few minutes then letting it cool down before drinking will kill more than 99.9 percent of all pathogens that can make you ill. Pretty simple stuff.
Of course it can be a real pain in the ass to boil every single drop of water you consume day in and day out. That's where a good filtration system comes into play. If you don't have a lot of cash to shell out right now for a survivalist wet dream of a filtration system Like a Berkey system (which can cost upwards of $300) or even a homemade Berkey then just go to Wally World and buy a cheap water filter there. $20 or less and your set.
Of course you're only set for a couple of months or so but in couple weeks when you have a few more survival dollars to spend buy a couple more cartridges for it. Before long you're survival water needs are taken care of.
Remember though you don't even need this as long as you start with clear odorless water and boil it before consuming. Water as stated earlier covers 70 percent of the earths surface. It falls out of the sky free of charge. So store a little water for emergencies but don't go overboard.
And for anyone who is still a little confused on what you can store water in remember this. If a food or beverage product came in the container it is safe to use for water storage.
