If you get a whiff of rotten eggs when you turn on the tap, you likely have hydrogen sulfide in your water. Hydrogen sulfide occurs naturally, often in deep wells, and is common in water with high iron levels.
There are no known health effects, but hydrogen sulfide can make the water somewhat corrosive to metals, such as steel or copper. It can also form yellow or black stains on kitchen and bathroom fixtures. Treatment methods may include aeration, filtration or chlorination.
