I tend to chuck in a water purification tab in to the water I collect. I'm 99% sure the water will be fine, but the tabs weigh next to nothing, and saves me having to boil the stuff before drinking it. I normally have a 3 litre bladder in the pack when I start my hunts, so I'm not in any hurry to find drinking water. Any water I collect on the way gets put into a new container and one tab per litre is added. All good to drink after 30 mins.
