No, not really. You don't need to boil the tap water in the United States, Canada, Western Europe, Japan, Singapore, or even Hong Kong.
Nonetheless, it's odd to find such question for Korea...
I don't think it's odd. As I stated earlier, I have two books which both advise against drinking the tap water in South Korea. There must be a reason for it.

and see a post by someone claiming that they got sick after drinking water in a restaurant in Korea - how do you know if the sickness is caused by water? There are many confounding factors.
Are you implying that Korean chefs don't know how to cook food to a safe temperature?
