| Abstract |
The report study evaluated the presence of volatile organics in raw domestic sewage generated in a subdivision and treated by a large 5-year-old community septic tank that had recently been cleaned by having the solids removed by pumping just prior to this study. Analysis showed the presence of priority pollutants in the raw sewage. Essentially no removal of these compounds occurred during the 2-day detention in the septic tank. The priority pollutants generally showed higher levels during the weekend, probably reflecting leisure activities and use of related chemicals (paint thinners, grease removers, toilet bowl cleaners, etc.), than during the week days. Most of the other volatile compounds were hydrocarbons, and their removal by the septic tank generally decreased with increasing molecular weight. Several organic sulfur compounds showed substantial increase as a result of anaerobic degradation processes in the septic tank. |
