What is Mercaptan?

Natural gas in its natural state is colorless and odorless; therefore, Mercaptan is added to natural gas to make it easier to detect a leak. Mercaptan contains sulfur and is harmless, but does omit a pungent smell similar to rotten eggs. The type of Mercaptan used by the City of Tomball blends well with natural gas and, in a gaseous state, has many of the same properties of natural gas so it will rise and dissipate. Mercaptan is only used to ensure the safety of our customers and the community.
