Development and Assessment of a Subsurface Landfill Fire Risk-index

摘要

Landfill subsurface fires create environmental hazards by emitting potentially dangerous particulates into the atmosphere and damaging liners, potentially contaminating surrounding soil and groundwater aquifers with leachate. Currently, the only means of detecting underground fires are physical tests. This paper is used to describe an index that can be employed to track fire risk across a landfill. The landfill parameters analyzed for fire risk susceptibility in Chapter 1 include residual nitrogen concentration, oxygen exceedance, methane concentration, carbon monoxide level, methane and carbon dioxide ratio and monitoring well temperature. Incorporating these factors, a landfill fire index ranging from 1 to 10 was developed in Chapter 2 that can be utilized by waste disposal facility operators to avoid fire incidents, fatalities, and environmental damage. A high index value indicates a high level of risk for landfill subsurface fire. Landfill operators can use the index to take preventive measures that reduce the economic and environmental costs of landfill fires.
