"Iodine tabs for water are temporary; you'll sooner or later run out of them. A Sweetwater or PUR filter will last a long, long time, and a plastic drop cloth, under the right conditions, will gather water (condensation) almost forever. It's stretched across a pit in the ground with a rock placed on the plastic in the middle. Place a cup under the plastic where the rock is. Ta-da! clean water."
Just as an add-on, I am not a eviormental expert so I don't know exactly how all this works, but i would assume that the rain and water could be contamianted by radiation, chemicals or biologicals, right? Are there any filtration systems that can protect against this? or any tests that can be done on collected water before drinking it?
