“But I filter my water!” you cry, clutching your Brita pitcher like a holy relic. Sorry to burst your bubble, but most pitcher filters are lazy bouncers. They catch dirt and a bit of chlorine, but they let most pharmaceuticals and microplastics waltz right through.

Reverse osmosis systems are the heavy hitters, but they cost a fortune and waste about four gallons of water for every one gallon they actually clean. That’s like hiring a security guard who sets the house on fire to check for intruders.

So what’s the verdict? Tap water is absolutely a mixture—a chaotic, multi-ingredient stew that would make a chemist laugh and a hypochondriac cry. It’s not pure, but it’s also not the end of the world.

Why You Shouldn’t Panic (Probably)
