I'm taking a short trip (two nights) to T.H. Stone Memorial St. Joseph Peninsula Park on the Florida panhandle in a few months (when the weather gets warmer). The peninsula is maybe a mile at it's widest point, and surrounded by salt water with a marsh on the interior. I have no idea how stagnant the marsh is, but it does support large mammals; there are dear running around the wilderness preserve.

Will the Katadyn Hiker that I use be safe to use on what could be a very stagnant, boggy marsh? Or will I have to pack in several pounds of water?
