Application of satellite remote sensing for a preliminary forensic investigation of landfill elevated

internal temperatures

S

ubsurface fires and smoldering events at landfills can present a serious health hazard and threat to the environment. These

fires are much more expensive and difficult to extinguish than open fires at the landfill surface. Initiation of a subsurface fire

may go unnoticed for a long time period. Undetected fires may spread over a large area. Unfortunately, not all landfills keep

or publish heat elevation data and some do not have a gas extraction system to control subsurface temperatures. The timely

and cost effective identification of subsurface fires is an important and pressing issue. In this work, we describe a method for

using satellite thermal infrared imagery at moderate spatial resolution to identify the location of subsurface fires and monitor

their migration within the landfill. The focus of the study is on the Bridgeton Sanitary Landfill in Bridgeton, MO where a

subsurface fire was first identified in 2010 and is still extant. Observations from Landsat satellite for the last seventeen years

were examined for surface temperature anomalies (or hot spots) that may be associated with subsurface fires. It is shown that

the location of hot spots identified in satellite imagery matches the known location of subsurface fires. Changes in the hot spot

location with time correspond to the subsurface fire spreading routes determined from

in situ

measurements. The results of the

study demonstrate that the proposed approach based on satellite observations can be used as a tool for landfill subsurface fire

identification and thus may be used by landfill owners/operators to monitor landfills and minimize expenses associated with

extinguishing landfill fires.
