Description:
Methane emissions were measured at two municipal solid waste landfills in California using static flux chambers, an optical remote sensing approach known as vertical radial plume mapping (VRPM) using a tunable diode laser (TDL) and a novel acetylene tracer method. The tracer method uses an ultra-sensitive, dual species gas analyzer based on wavelength scanned cavity ring-down spectroscopy that has been developed to measure the concentrations of methane and acetylene with the required sensitivity. The static chamber and VRPM measurements were made on sections of the landfills with active landfill gas collection systems and intermediate or long-term soil covers. Mobile and stationary tracer plume measurements were made at distances of 0.5 to 3 km from the landfills. Field measurements were performed over a period of several weeks during the fall of 2009 with each landfill being measured twice using the static chambers and VRPM approach. A single set of tracer plume measurements were made at each of the landfills. Mean methane emission rates determined from the VRPM and chambers will be presented and compared to methane flux results obtained using the acetylene tracer method.
