Public Health Statement for Hydrogen Sulfide - Centers for …
Hydrogen sulfide can be found in well water and can be formed in hot water heaters, giving tap water a rotten egg odor. Cigarette smoke and emissions from gasoline vehicles contain hydrogen sulfide.
Hydrogen sulfide is formed when soluble sulfides are hydrolysed in water. In water, hydrogen sulfide dissociates, forming monohydrogensulfide(1-) (HS-) and sulfide (S2-) ions. The relative concentrations of these species are a function of the pH of the water, hydrogen sulfide concentrations increasing with decreasing pH.
Hydrogen Sulfide in Well Water - (Rotten Egg Odor)
Hydrogen sulfide is a colorless gas that can exist naturally in groundwater. Sulfur-reducing bacteria produce sulfide in an anaerobic reaction in several ways, including fermentation (part of the “rotting” smell), and as a form of respiration, much …
What can cause our water to have an earthy odor or to smell like …
In some parts of the country, drinking water can contain hydrogen sulfide gas, which smells like rotten eggs. This can occur when water comes into contact with organic matter or with certain minerals, such as pyrite.
Hydrogen Sulfide in Drinking Water - Vermont Department of …
What You Need to Know About Hydrogen Sulfide in Drinking Water. Hydrogen sulfide gas can occur in wells anywhere in Vermont and gives the water a characteristic "rotten egg" taste or smell. Hydrogen sulfide gas or sulfur bacteria in your water can cause other problems:
Hydrogen Sulfide and Sulfate | UGA Cooperative Extension
2014年4月14日 · Hydrogen sulfide is insoluble in water, but underground, this gas remains trapped within the water. When the water is pumped to the surface, the hydrogen sulfide gas escapes and is therefore easy to smell.
FACT SHEET: HYDROGEN SULFIDE IN DRINKING WATER Water containing hydrogen sulfide usually does not pose a health risk, but does give water a nuisance "rotten egg" smell and taste. Water supplies with as little as 1 ppm (part per million) hydrogen sulfide are corrosive and may tarnish copper and silverware.
Hydrogen Sulfide in Drinking Water Causes and Treatment …
2021年12月7日 · If your drinking water smells like rotten eggs, it contains hydrogen sulfide. This leaflet discusses how hydrogen sulfide is formed and how to correct the problem. (6 pages)
Hydrogen sulfide gas can give water a “rotten egg” taste or odor. This gas can occur in wells anywhere and be: Naturally occurring—a result of decay and chemical reactions with soil and rocks. Produced by certain “sulfur bacteria” in the groundwater, well, or plumbing system.
Sulfur in Water: Sulfur, Sulfate, and Hydrogen Sulfide
2019年12月4日 · Two forms of sulfur are commonly found in drinking water: hydrogen sulfide and sulfate-reducing bacteria. Both forms are nuisances that usually do not pose a health risk at the concentrations found in domestic wells.
Hydrogen Sulfide in Water: Sources, Tests, Effects, Removal
Hydrogen sulfide is a gas that is naturally present in water. It’s a colorless and flammable gas. It has a strong, unpleasant odor that is often described as smelling like rotten eggs. This gas is soluble in water, so it can easily end up in groundwater or surface water.
Hydrogen Sulfide and Sulfate in Private Drinking Water Wells
Indication of Hydrogen Sulfide and Sulfate in Drinking Water. Hydrogen sulfide gas produces an offensive “rotten egg” or “sulfur water” odor and taste in the water. Most people can detect hydrogen sulfide in water at concentrations as low as 0.5 milligrams per liter.

NASD - Hydrogen Sulfide in Household Water
Water containing hydrogen sulfide, commonly called sulfur water, has a distinctive "rotten egg" odor, which may be especially noticeable when running hot water. Such water can discolor coffee, tea and other beverages, and alter the appearance and taste of cooked foods.
A test for hydrogen sulfide or sulfur bacteria is not usually necessary. However, in rare instances, the gas may be from sewage or other pollution. To be safe, test your well water for coliform bacteria and nitrate. To find an accredited laboratory, visit https://go.usa.gov/xdJHk.
What are the effects of hydrogen sulfide in well water?
Hydrogen sulfide (H2S) is a gas responsible for the distinctive “rotten egg” odor often detected in water. It is usually encountered in wells drilled into acidic bedrock, such as shale and sandstone and occurs naturally in groundwater due to the activities of sulfur-reducing bacteria.
