What is typically monitored at a landfill? What will be an ideal response?
The primary concerns are water and explosive gas. Monitoring wells are employed to detect the escape
of leachate from a landfill site and to observe the quality of existing groundwater resources. But
decomposition-derived methane gas can also escape from the site and can be explosive if it is
concentrated enough. In some instances, methane is harvested and burned to produce electricity,
thereby eliminating the hazard while simultaneously producing power.
