Natural gas is one of the safest, most efficient and most reliable forms of energy available. 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 Virginia DirectLink at 1-800-543-8911 and we'll send you a "scratch 'n sniff" card that provides you with a sample of the odor.
