Wasn`t sure where to put this so please move if it`s in the wrong section. Just wanted to ask what others use to purify drinking water when camping? My dad used to take us camping regularly throughout Scotland all during childhood and I`ve camped a lot during my adult years, (usually avoiding commercial campsites as I`m an anti social auld wumman) and in all that time, he would get our drinking water from the nearest burn/loch/spring and simply boil it, nothing else. Though, well, y`know that old joke about the dead sheep upstream....? Yup, it happened to us...got the tents and gear all set up, decided to take a look around (Border country, in the hills around Innerleithen) and walked uphill following the stream only to find a few weeks-old dead sheep, head still in the burn. I grabbed hold of the back legs and shifted it higher onto the banking clear of the water and went back down to inform dad, who said "Never mind, it`ll no` drink much noo".... and we just kept on boiling the water. In all those years, we never caught anything from it, though that may simply have been blind luck and nothing else. Nowadays we use purification tablets on top of boiling, forget the name of them but can`t pronounce it anyways as my Belgian fiance brings them back from Antwerp with him after one of his trips back there. Does anyone else simply boil and drink, or do you all use tablets or filters of some kind?
