Hydrogen Sulfide

Testing for hydrogen sulfide in water is important because of its strong odor, taste, and corrosive nature. Even at low concentrations, it can make water unpalatable. At higher levels, it can corrode plumbing and stain laundry and fixtures. It’s also a marker for the presence of other harmful bacteria and substances in water.

Hydrogen sulfide significantly affects the taste and quality of drinking water. Its strong “rotten egg” odor is often detectable at very low concentrations and can make water unpleasant to drink. It can also cause staining and corrosion in plumbing and fixtures, affecting the overall water quality.

While occasional exposure to low levels of hydrogen sulfide in drinking water is not usually harmful, long-term or high-level exposure can be problematic. It can cause dehydration and other gastrointestinal symptoms. Inhaling the gas from water can cause respiratory irritation and, in extreme cases, more serious health issues.

Hydrogen sulfide in water commonly originates from natural sources like decaying organic matter and sulfur-reducing bacteria, especially in groundwater. Industrial processes, sewage pollution, and plumbing systems with stagnant water can also contribute to the presence of hydrogen sulfide in water supplies.
