Not all odors in ,wastewater, are from H2S, and there is no correlation between H2S and other odors. The total H2S procedure is good up to 18 mg/1, and higher concentrations must be diluted before testing. H2S production ,can, be controlled by up-sewer aeration which reduces US formation and also stabilizes the ,wastewater, in the collection svstem. 14-104
