FULL STORY. Hydrogen sulfide is a foul-smelling gas with an odor resembling that of rotten eggs. Sometimes called swamp gas, this toxic substance is generally associated with decaying vegetation, sewers and noxious industrial emissions.
The first thing to do is make sure the smell is sewer gasâusually a rotten egg smellâand not a natural gas smell, which usually smells like a skunk. If you think itâs a natural gas smell, call your natural gas company immediately.
