If the ,wastewater, is exposed to the atmosphere, H2S will be released and a typical rotten egg odor will be detected. Anaerobic bacteria found in ,wastewater, can liberate H2S from the solids. When the gas leaves the ,wastewater, stream and comes in contact with moisture and oxygen, sulfuric ,acid, is formed which is very corrosive to concrete.
