You’ve probably never tasted it—thankfully, because methane is odorless and tasteless in water. But it’s hiding in some places you might not expect. Have you ever walked past a swamp or a stagnant pond and noticed little bubbles rising to the surface?
Those bubbles are called “swamp gas,” and they’re mostly methane produced by tiny bacteria munching on dead plants underwater. A little bit of that methane dissolves in the swamp water before making its escape to the air. It’s nature’s own tiny soda factory, but without the tasty flavor.
Farmers also deal with dissolved methane in manure lagoons (yep, that’s a polite term for it). The bacteria in that rich, earthy slurry produce methane, and some of it stays dissolved until it eventually bubbles up. It’s not exactly dinner table conversation, but it’s a real thing!

Methane and your morning coffee? Not quite
You might wonder, “Should I worry about methane in my tap water?” The short answer is no. Municipal water systems are designed to remove or vent dissolved gases before it reaches your faucet. Your morning coffee is safe from making you burp like a cow.
But there is one quirky exception: ice cores. Scientists drill deep into glaciers and find ancient air bubbles trapped in the ice. Those bubbles contain methane that dissolved into ancient meltwater and then got frozen in time. It’s like a tiny time capsule of Earth’s atmosphere from thousands of years ago.
