I agree, the waters here are very clean once you move away from civilization. There are very few cases of Giardia reported, however I still treat my water if I have any doubt as to it's source....especially in some low mountain areas where there are open range cattle grazing. That creek water may look and taste pristine where you are, however miles away and above you there could be herds of cows that have little disregard for sanitation practices...
