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.
But, like any energy source, natural gas must be used properly. Since natural gas is colorless and odorless, we add a harmless, non-toxic chemical that makes it easier to detect a gas leak before it can create a hazardous situation. The chemical, called mercaptan, smells a lot like rotten eggs. If you aren't familiar with it, call Columbia Gas of Massachusetts at 1-800-688-6160 and ask for a scratch-n-sniff card that provides you with a sample of the odor. In a concentrated form, the smell is almost unbearable.
