That rotten-egg odor isn’t a sign your well is haunted. It’s usually caused by hydrogen sulfide gas—a natural byproduct of organic matter decaying underground.
Think of it as the Earth’s version of a compost bin, but for your water supply. And while it’s mostly harmless in small amounts, it can also indicate sulfur bacteria thriving in your plumbing.
Fun fact: Ancient Romans used sulfur compounds in their baths for purification, but they probably didn’t enjoy the smell either.
Step One: Diagnose the Culprit Before You Fix It
Before you invest in gadgets, do a simple sniff test. Run cold water from a glass, then hot water from the tap—if only the hot side smells, you’ve likely got a water heater issue.
If both cold and hot water reek, the problem is deeper, usually in your well or pipes. And if the smell disappears after a few minutes? You might be dealing with chemical reactions inside your plumbing, not the source itself.
Pro tip: Fill a bottle halfway, shake it, then smell—if the odor intensifies, you’ve got dissolved gas that can be easily treated.
