Previous studies have indicated the potential for emissions of volatile organic compounds (VOCs) from industrial and municipal sewers. However, existing estimation methods can significantly overestimate emissions of VOCs over a wide range of sewer operating conditions. This paper reviews three methods for estimating emissions from sewer reaches: equilibrium, open trench, and cocurrent ventilation. A new methodology is presented that combines both equilibrium and open-trench approaches. The maximum error associated with this combined model is shown mathematically to be 58% and independent of flow and reach characteristics.
