A book was recently published entitled something along the lines of
"Lessons of Long Distance Hiking" (forget the exact title!), by Roland
Muesser.  This book is essentially a compilation of statistics about long
distance hikers.  In one study the author did, the rate of giardia among
those who filetered/treated/boiled water was the same as those who did
not treat their water in anyway!  It appears giardia, in most cases,  is
more a symptom of poor sanitation habits that is sometimes part of the
backcountry experience.
