Odour and VOC impact assessment and air quality monitoring program at a municipal solid waste landfill

The scope of this paper is to present and compare the results of (1) an extensive odour, VOC and H₂S impact assessment, and (2) a complete odour, VOC and H₂S air quality monitoring program at a municipal solid waste landfill (MSWL). This study was conducted over a year, with an unprecedented amount of cross-assessment techniques and data points on a 1.3 million tonnes per year MSWL. All potential landfill emission sources were characterized for odours, VOCs, CH₄ and H₂S using a set of over 150,000 onsite samplings & measurements. An air quality monitoring program included continuous odour, CH₄ and H₂S monitoring, a 12-day-frequency VOC sampling campaign, and a 24h/7d odour survey at the nearest receptors. This paper will present the standardized methodologies used and comparative results from each independent assessment program.
