If the smell is sudden and very strong, like someone popped a sulfur balloon in your basement, you might have a dead animal in your well. Yes, a mouse, bird, or worse. This is a biohazard, not a chemistry problem. Stop using the water, call a well driller immediately, and maybe light a candle.
Otherwise, if your DIY shock treatment fails after two tries, or if you have high iron levels alongside the smell, just hire a water treatment pro. They’ll test your water, design a system, and laugh at your “bleach in the well” story—all for a fee. It’s worth it to reclaim your morning coffee without the sulfur aftertaste.
And remember: you are not weird. Millions of people live with this. You’re just one filter away from water that smells like, well, nothing. And nothing has never smelled so good.
