First, please don’t just light a candle and hope it goes away. Grab a glass, run the water, and do some detective work. Here’s a quick checklist:
✔ Smell only when hot? Fix the water heater (anode rod replacement often works).
✔ Smell from all taps? Test your well water for sulfur, iron, or bacteria.
✔ Smell worse after rain? Check for surface water seeping into the well cap.

You can also try an aeration system—basically a fancy bubbler that kicks the gas out before it hits your glass. Or a carbon filter. Or a chlorinator if bacteria are partying in your pipes. Yes, this costs money. But so does buying bottled water forever.
When to call in the cavalry (a.k.a. a professional).
If you’ve bleached your well and it still smells like a swamp monster’s bathwater, stop Googling and call a certified well driller. Seriously. They have tools that can sniff out issues from 200 feet underground. And they won’t judge you for the smell—they’ve seen worse.
Also, if you notice a sudden change in smell and color (like murky or green water), don’t drink it. That could indicate a cracked well casing or contamination from heavy rain. Better safe than stuck on the toilet for a week.
