Msw landfill measurements l.jpg

MSW Landfill Measurements Remote Sensing (ORS) for Emission Monitoring



Future activities l.jpg
Future Activities Landfill

  • Method improvement and application validation -- DOD’s ESTCP Program supported project

  • Agricultural ammonia sources -- broilers, hogs, and cattle

  • Landfills -- MSW bioreactors and brownfields

  • Diesel emissions -- weigh station and cross road studies

  • Incorporate Tunable Diode Laser (TDL) system into program


Summary l.jpg
Summary Landfill

  • Radial scanning has demonstrated the ability to locate point sources within the field of measurement

  • Initial deployment of radial scanning on a large landfill is scheduled in September

  • Plane-integrated (PI) OP-FTIR has been used to evaluate the effectiveness of a lagoon biocover to control ammonia emissions

  • Single path and PI OP-FTIR measurements have been made on a large high-rise layer house - data analysis is not finished
