A Drink! To Your Death

While many people refuse to drink tap water in Korea, and as he points out himself, bottled water is not much safer. At least with tap water you boil and filter it (we do). Plus I believe all of Seoul's water is managed by a municipal agency and pumped out of the Han River, upstream of Seoul. I guess that would be better than pumping it downstream from Seoul. But I would not drink straight from the tap either. Boil, then filter.
