Chlorine is added to public water supplies to kill bacteria and viruses. Think of it as the invisible bouncer at the club, keeping the bad guys out of your glass.
The faint "pool-water" scent? That’s just the guard’s aftershave. It’s completely safe—and actually a sign your water is working hard to protect you.
Let the glass sit for a few minutes, or pour it between two glasses, and poof—the smell vanishes like a bad joke.
When the Smell Gets Fancy: Sulfur
What about that rotten egg smell? Don’t panic—it’s not your plumbing’s last stand. That’s hydrogen sulfide, a natural gas from deep underground.
If you live near volcanic rock or old wells, your water just has a little earthy swagger. It’s still safe to drink, though it might not pair well with your morning coffee.
A quick fix? Run your tap cold for 30 seconds before filling your glass. The smell usually comes from bacteria hanging out in your water heater, not the main supply.

The "Dirty Socks" Mystery
Okay, this one is wild: a musty, wet-dog smell. That’s often your kitchen faucet’s aerator—the little mesh screen at the tip—being a bit of a hoarder.
It traps tiny bits of grit and organic matter. Over time, that stuff starts to party, and the party smells like damp laundry.
The answer is comically simple: unscrew the aerator, soak it in vinegar for an hour, and rinse. You’ll feel like a plumbing wizard, and your water will thank you.
