Natural gas is colorless and has no scent. We add a strong odorant that smells like rotten eggs to help you detect possible leaks. If you suspect a leak, call 1-800-ALLIANT (800-255-4268) immediately. We will investigate for free. Protect yourself and your family by learning the signs of a leak and what to do.
