Purifying water

I wanted to boil some vegetables and I wanted to use the water from the tap to do it.

How long did I need to boil the water for the water to be purified for cooking the vegs?

I was thinking 10 minutes, but here is what I found on the web. HEY! Before you click that link, what is your guess?
