What is Sulfide?
Sulfide is an inorganic anion of sulfur. It is a strong base and good reducing agent. Sulfides are naturally present in ground waters as a result of leaching from sulfur-containing mineral deposits. Surface waters usually do not contain high sulfide concentrations. Sulfides result from the decomposition of organic matter, bacterial sulfate reduction under anaerobic conditions, and various chemical processes. Dissolved free sulfides are very aggressive corrosives especially to metals like steel, stainless steel, and copper. Sulfides in aqueous solution are responsible for stress corrosion cracking of steel.
Sulfide Exposure and Health Risks
Sulfides readily form Hydrogen Sulfide which is a very toxic and corrosive gas. Some sulfides are highly flammable, and when they burn they produce sulfur dioxide gas.
Regulations
The EPA and CDC do not have any listed restrictions or regulations on sulfide levels
Measuring Sulfide
Dissolved Sulfide concentration in water can be measured in units of parts per million (ppm). We carry instrumental kits from CHEMetrics and monitors from ATI that determine Sulfide levels in water. All of our Sulfide products can be viewed HERE.
