Here’s a doozy: your tap water might contain traces of prescription drugs. Antidepressants, antibiotics, birth control—yes, people flush them, and water treatment plants aren’t designed to filter them. The levels are tiny, but still, imagine drinking your neighbor’s anxiety meds. You might suddenly feel calm about your lousy commute.
Another fun fact: fluoride is added to most municipal water to prevent cavities, but too much can cause fluorosis—white spots on teeth. If your water’s got above 0.7 milligrams per liter, you’re basically drinking toothpaste. Not dangerous, just weird.

And the wildest one: the plastic bottle you’re tempted to buy instead may not be safer. Many bottled waters are just tap water bottled with a fancy label, and they’ve been found to have microplastics. So testing your tap might actually be less depressing than testing your Fiji.
