What Is Hydrogen Sulfide Bacteria?

Sulfur bacteria in a water system can lead to corrosion of the pipes.

Sulfur bacteria, or sulfate-reducing bacteria, are naturally-occurring bacteria that use the sulfur in decaying organic matter as an energy source. Hydrogen sulfide, a foul-smelling gas, is produced as a byproduct.

Harmless

Sulfur bacteria are harmless in themselves, but hydrogen sulfide in a water system can be very annoying. It is toxic in high concentrations.

Slime

The bacteria can cause a white, gray, black or reddish brown slime that can clog pipes, wells and plumbing.

Other bacteria

Sulfur bacteria can encourage the growth of other bacteria, such as iron bacteria.

Source

Sulfur bacteria can be present in a well or its distribution system, and/or in water treatment devices, such as a water softener or water heater.

Corrosion

Hydrogen sulfide can also corrode pipes in the indoor plumbing system and/or the water distribution system for a well.
