The technical objective of this project was to obtain data for evaluating volatile carbon (VOC) emissions from wastewater treatment facilities for the synthetic organic chemicals manufacturing industry (SOCMI). VOC emissions data were obtained using the Concentration-Profile technique and were compared to emission rate data obtained by predictive modeling. Methods for sampling and analysis of VOC emissions in ambient air were evaluated and refined to obtain the necessary data. The comparison of measured and predicted flux rates was performed on data obtained from two wastewater treatment facilities; one that used forced aeration and one anaerobic facility. The field sampling procedure (Concentration-Profile) involved determining temperature, wind speed and VOC species concentrations at six logarithmically spaced heights above the water surface. VOC species were determined by collecting time integrated air samples in evacuated stainless steel canisters and analyzing these by cryogenic concentration and high resolution gas chromatography using simultaneous flame ionization and photoionization detection.
