A friend says he stores water in large containers for emergency situations and just pours in a table spoon of bleach to preserve it. At first I was like "Who are you, Amanda Todd?". But he explained to me that a little bleach diluted in a large amount of water isn't that damaging and that it will preserve it. Is he right or wrong? I myself, to cut down on the cost of bottled water (because I need to cut costs as much as I can) use a Britta Filter Jug to filter water straight form the tap - because it's already included in rent (so almost free) (a pack of 8 filters costs like $35 and lasts 14 months). He said that in an emergency situation when plumbing doesn't work, it'll be useless. So I guess I better get some large containers, go to the drug or grocery store and buy a small thing of Clorox and start preserving. I already have a bunch of non-perishable food, (as I don't do well with food that goes bad [it always goes bad before I eat it] ). As far as defence wise I may not have firearms yet, but I have pellet pistols and rifles but they all operate on co2 and in an emergency situation my supply of Co2 may run out, should get something break-barrel or try to get a P.A.L and real firearms as soon as I can. Of course for killing or significantly injuring someone if my life depends upon it, id have to get lucky with shot-placement but pellet stuff should be good for small-game if I want some meat. Luckily I was in cubs and scouts for a bit, so I know how to make make-shift shelters, what plants can be used for different purposes, etc so I have skills in that area, as well as a little knot tying experience. But this thread is mainly about water, is this the way to store emergency supplies or is my friend bat shit crazy?
