Abstract

This report discusses a new measurement technology for characterizing emissions from large-area sources. The site selected for demonstrating this technology is a Superfund landfill being evaluated for recreational use. Data on methane and air toxics were needed to help determine any increased risk to those using the site. Open-path Fourier transform infrared spectrometers were used to provide data on both background and surface emissions.

The technology provides concentration maps indicating the spatial variability and areas where additional control may be needed. Using a multiple-beam configuration, horizontal scans were conducted to identify any hot spots and vertical scans were conducted to determine the mass flux. Optical remote sensing radial-plume mapping provided concentration mapping of the site. These data will be used to make decisions about potential recreational use of this site.
