Abstract

Elevated temperature events are problematic for Subtitle D landfills because they: (1) are challenging to identify and delineate; (2) can remain undetected for a relatively long period of time; (3) are difficult to extinguish; (4) may damage engineered components, (5) direction and rate of movement are not uniform, and (6) produce side effects that may damage a facility enough to warrant permanent closure. In addition, slope instability and movement have occurred at these landfills with elevated temperature, leachate, and/or gas pressures. This paper discusses the mechanisms for slope instability, including elevated gas pressures, perched leachate surfaces, and reduced MSW shear strength. Based on a case study, slopes are found to move outwards of up to 15 m. In addition, the slope can reverse backwards into the settlement bowl if settlement is excessive.
