Yes, overwhelmingly so. In most developed countries, tap water is tested more often than the bottled stuff. It’s not a pure substance, but it’s a safe mixture. That little bit of chlorine keeps you from getting sick, and the minerals? Your body actually needs those.

The problem really starts when people don’t understand the “mixture” part and panic. They see a white film on their kettle and think it’s poison. Nope. It’s just calcium carbonate, the same stuff in antacid tablets. You can even eat it — though I wouldn’t recommend it with chocolate.

A real story from my kitchen

Last week, my wife filled a glass from the tap and left it on the counter overnight. The next morning, we noticed a few tiny white flakes floating at the bottom. “Eww, what’s that?” she asked. I smiled, because I’d just written this article. “That’s your water’s terroir,” I said, stealing a wine term. “It’s mineral deposits settling out.”

She gave me that look — the one that says “you nerd.” But then she drank it anyway. Because she knows that while it’s not pure, it’s perfectly fine. And honestly, the jargon makes it feel kind of fancy, like you’re sipping from a mountain spring instead of a suburban pipe.
