What is the components of solid waste?
He 24-inch thick barrier protection layer composed of soil and the
overlying six inches of vegetated topsoil serve to protect the
underlying geomembrane and promote rainwater run-off away from the
landfill.
A 60 mil (0.06 in) thick (or 40 mil (0.04 in) thick, depending on the type of material used) geomembrane,
along with the underlying low permeability clay layer, form a composite
barrier cover system which prevents infiltrating rainwater from
reaching the solid waste buried in the landfill and generating
additional leachate.
The gas venting layer collects and controls landfill gases generated by the decomposing waste mass.
The waste mass may be greater than one-hundred and fifty feet thick.
The primary leachate collection and removal system consists of a
series of drains and pipes within a layer of sand or gravel designed to
collect all of the liquid leachate which has drained through the waste
mass. A 60 mil thick geomembrane underlies the leachate collection
system. On the bottom of the landfill, the 60 mil geomembrane is
underlain by a clay layer or GCL (a thin manufactured layer of very
strong textiles and extremely low permeability clay) component to make a
composite liner. The collected leachate is sent to a wastewater
treatment plant.
The landfill's secondary leachate collection and removal system is a
backup series of drains and pipes within a layer of sand or gravel
designed to collect any leachate which was not contained by the primary
liner system. A 60 mil (0.06 in) thick geomembrane underlain by a 24
inch thick clay layer or GCL comprises the secondary composite liner
system which acts as secondary containment for leachate.
This design serves to protect the environment from contaminants which
may be present in the municipal solid waste. The landfill siting plan,
which prevents the siting of landfills in environmentally sensitive
areas, as well as on-site environmental monitoring systems, which
monitor for any sign of groundwater contamination and for landfill gas,
provide additional safeguards.
