I don't drink straight from the tap. However, it also stated we should drink water that's only boiled once, and not left for more than 24 hrs. Despite boiling my water, I guess I'm drinking "unhealthy" water afterall. Honestly, how to drink the whole kettle of water within 24 hrs!!
Another point it made is not to drink bottled water (distilled, mineral) that's more than 3 days old. How is that possible?? I wonder how long the water has stayed inside those bottles before reaching our shelves, and how long it has been sitting on those shelves before finally bought by us.
It's either these water are really bad for our health, or my understanding of the language is not there.
