We're looking at getting started on our prepping; nothing crazy, but enough food, water, light, and essentials for up to a couple months of grid failure. My issue with water is this: we don't really have a good set up for being able to store whole barrels of water, but we could do 5- or 6-gallon bottles or jerry cans pretty easily. Do you get distilled or purified for better storage life? I hear distilled stays good longer, but you need to add a mineral supplement or it starts to leach minerals out of your body over long-term consumption. Also not sure about how safe it is to leave water in plastic long-term. Is there gradual contamination of the water with the compounds in the bottles? Any other ways to approach this issue? I'm new to this, so bear with me.
