Book 30, Question 85
Is tap water or bottled water better?
In places like Canada, tap water is treated and tested often, and it costs much less than bottled water.
Bottled water can be useful during emergencies and travel, but it makes lots of plastic waste and uses energy to transport. A reusable bottle filled from the tap is a simple choice for most days. If you're ever unsure about a water source, ask a grown-up.
