How does a sanitary landfill differ from an open dump? What will be an ideal response?
In a sanitary landfill, each day's trash is sealed under a layer of soil, which, it is hoped, isolates it from
the rest of the environment. Heavy equipment is used to spread the trash and compact it in thin layers.
Also, when the landfill is complete, it is sealed under a 50-centimeter thick layer of soil, which is
graded in such a way as to promote surface drainage away from the fill. The basic idea is to prevent
infiltration, which may lead to leaching within the fill mass.
