![]() You can find local state-accredited water testing labs by contacting the Pennsylvania Department of Environmental Protection. Consult with local state-accredited commercial water testing laboratories to determine if they can test for hydrogen sulfide in water. Testing for hydrogen sulfide must be done in the home or the sample must be chemically stabilized before being sent to a commercial testing lab. Testing the water to determine the concentration of hydrogen sulfide may be helpful when choosing between water treatment devices. ![]() Hydrogen sulfide does not have a drinking water standard because it makes the water aesthetically undrinkable long before it reaches harmful concentrations. Hydrogen sulfide can also cause corrosion of metals in a plumbing system, and it can cause yellow or black greasy stains on fixtures or inside pipes when it forms metallic sulfides. Most people can detect hydrogen sulfide levels well below 0.5 mg/L. While the gas is poisonous and flammable, the human nose can detect it well before it causes health concerns. Hydrogen sulfide in water is an aesthetic concern that causes a disagreeable taste and odor to the water. ![]() In this case, the softener provides a favorable environment for sulfur-reducing bacteria to grow. In rare cases, the addition of water treatment equipment, like a water softener, may cause the production of hydrogen sulfide. The magnesium rod can chemically reduce sulfates to form hydrogen sulfide. Water heaters are fitted with a magnesium rod to inhibit corrosion of the heater. In this case, chemical reactions within the water heater may be the source of the rotten egg odor. Sometimes hydrogen sulfide may be noticeable only in the hot water in the home. Hydrogen sulfide problems are most common in wells drilled into acidic bedrock such as shale and sandstone. Although sulfur-reducing bacteria can impart taste and odor in the water, they do not cause health concerns for humans. Hydrogen Sulfide occurs naturally in groundwater as a consequence of the activities of sulfur reducing bacteria. These bacteria feed on small amounts of sulfur in the water and thrive in the low oxygen environments present in groundwater wells and plumbing systems.
