There's a good discussion of drinking outdoor water on
http://www.yosemite.org/naturenotes/Giardia.htm.
I do a lot of canoeing in remote areas on rivers just swarming
with beaver. I hydrate myself with tea so sterilizing water
by boiling is no problem. But I do admit to dipping my cup
in the middle of big lakes where the nearest beaver is miles
away.
