Not sure how comparatively inconvenient boiling may be. Much will depend upon the time required =I have seen sources that claim you should let the water boil for ten to fifteen minute.Most go for a shorter period.

James Wilkerson MD, author of Mountaineer Medicine, recommends bringing water to a boil and then letting it cool. stating that pasteurized milk is heated to 165F and held there for a bit.
this is hardly inconvenient if you are prepping coffee or tea, which i do often. Many alternative water treatments require fairly long intervals before ingestion, probably accounting for the popularity of filtering.

If push comes to shove, I will just go ahead and drink up. It will take a while for problems to develop, and by then I will be in contact with medical facilities (usually).
