Dissolved Sulfide

Sulfides (also spelled Sulphides) can be found naturally in well water and can build up in wastewater collection systems due to anaerobic conditions. In drinking water systems, sulfides cause taste and odor problems and in wastewater systems, sulfides cause damage to concrete structures in collection systems and contribute to odor problems in treatment facilities. In addition, sulfides are used in mercury removal processes and are frequently found in tanning wastes.

Sulfides give water a bitter taste and the odor of rotten eggs and if left untreated makes it unsuitable as a source of municipal drinking water. However, with appropriate, reliable and accurate monitoring and treatment, the water can then be made available to the public.
