Description:
This report focuses on three field campaigns performed in 2002 and 2003 to measure fugitive emissions at a bioreactor landfill in Louisville, KY, using an open-path Fourier transform infrared spectrometer. The study uses optical remote sensing-radial plume mapping. The horizontal radial plume mapping (HRPM) method was used to map surface concentrations, and the vertical radial plume mapping (VRPM) method was used to measure emissions fluxes downwind of the site. Surveys were conducted in five areas at the landfill site.
The As-Built Area was found to have the highest methane fluxes. In addition to VRPM surveys, HRPM surveys were performed in the As-Built and Retrofit areas. Two definitive methane hot spots, having concentrations over 80 ppmv were found at the Retrofit Area during the September 2002 campaign. During the May 2003 campaign four hot spots were found in the As-Built Area (the most intense having concentrations over 210 ppmv), and two hot spots were found in the Retrofit Area (the most intense having concentrations over 78 ppmv). During the September 2003 campaign, three hot spots wee found in the As-Built Area (the most intense having concentrations over 34 ppmv).
Further evaluation is needed to establish trends in fugitive emissions as the bioreactor areas continue to operate over time.
