Yes, it is. But it's unfortunately necessary at times. When I was on foreign travel if I couldn't boil my own it was either pay for water or some other drink, or suffer a day+ of diarrhea, lol. And I've lived in some run down places in the states, or places like NYC, where the pipes are old as fuck. You can get a basic water test kit from Home Depot, etc., it's interesting what you might find. @ MedicineCabinet, Fiji water is another fucked up brand if you google them.
