I know this has probably been addressed a thousand times here already, but I am new to the forum and just recently took up hiking again and would like to know the safest "modern" methods to use. Years ago I just used iodine tablets to purify water from streams, but have heard recently about filters and ultraviolet pens and all sorts of things that I am unfamiliar with. Any help would be greatly appreciated. Thanks! <img src="/forums/images/graemlins/confused.gif" alt="" />
