Hydrogen Sulfur

Where Does Hydrogen Sulfur Come From?

Hydrogen sulfur in the Northwest most commonly comes from an iron reducing bacteria that occurs naturally in well water, which results in a rotten egg smell. Iron is one of the food sources for the iron-reducing bacteria. Hydrogen sulfur can also result from decaying vegetation or chemical reactions due to naturally occurring elements in the earth’s crust.

What are the Health effects of hydrogen sulfur?

The iron bacteria is a non-pathogen, and not a threat to your health. In most cases the hydrogen-sulfur gas is not a health issue, except for in circumstances where the smell is strong enough to be noticeable at all times, in which case it must be treated.

Treatment methods

Depending on the frequency and level of hydrogen sulfur gas, something as simple as an absorption method using carbon can be effective at removing hydrogen sulfur gas. However, in most cases, an aeration system or iron filter is needed.
