• First Thing Leachete* comes in contact with
• Leachate can contaminate the earth’s groundwater
if not pumped to a storage area (like a pond) and
then transported to a water-treatment plant.
• Helps protect the Geomembrane from heavy
machinery, such as garbage trucks, bulldozers,
and garbage compacting equipment.
•*Leachete- (liquid that
flows through the
landfill from people’s
The geomembrane is the plastic liner of the landfill
The geomembrane must be carefully handled because on a windy
day, the plastic liner can go wild. If the plastic liner is not handled
carefully it could cause a big disaster seeing that one roll of the
plastic liner is about a ton
The geomemebrane along with clay reinforce the bottom and
sides of the landfills
The EPA has admitted that even with the plastic liner there for
the landfill, the landfill will eventually leak
The EPA landfill inspectors are only required to check the
landfill after 30 years, while the geomembrane warranty only lasts
What has the EPA
admitted about the
• Usually 4 feet deep, lies under the plastic tarp
• environmental precaution, protects the
plastic tarp from puncturing objects
• Good environmental protection because of its
low ability for liquid to flow through it. If by
any chance leachate (the liquid) were able to
surpass the geomembrane, it would take
years for it to make it all the way through the
four feet of clay lining.
• The foundation is the lowest level in the
• The objective of this construction
technique is to keep the entire landfill from
direct contact with the ground water so the
waste does not pollute it. Like the roof of
a house the foundation has slope, which is
designed to allow liquids seeping from
above or below to flow to a storage area.
1.What is Leachete?

Methane gas is a green house gas.
37% of the methane are from landfills

How is Methane dangerous to the earth?
Trash Incineration (burn)
Only 10-20% of hazardous wastes can be safely
There are some state operated trash incinerators that
convert the energy produced by the burning trash into
When the trash is burned, it leaves behind ashes
The ashes are often buried under different
They are sometimes mixed in with pavement
Sometimes they are dumped into holes in the
Often they are dumped in a LANDFILL
While trash is being incinerated, the fumes
released are often toxic, and can threaten
those who breath them in
The ashes are TOXIC!
When the ashes are mixed with pavement, they
eventually leak out and contaminate the
When the ashes are buried, they also leak out
into the groundwater
F.Y.I., burning trash in a barrel is now illegal in
most of the country, excluding some rural areas

A landslide is the slipping down of a mass of rocks or
earth on a steep slope
A landslide, resulting in about $2 billion dollars in repair
and taking about 25-50 lives annually, can be extremely
Places where landslides have occurred since 2004 are
Haiti, Kyrgyzstan, Peru, China, Colorado, Indonesia,
Vietnam, Ecuador, Kazakhstan, California, Pakistan,
Washington, and Pennsylvania
About how much does a landslide
cost in repair?
Starting of a Landslide Landslide Entering the Valley
• Landfill regulations enforce how a landfill should be designed
• Location Restrictions ensure that landfills are built in suitable geological
areas away from faults, wetlands, flood plains or other restricted areas.
• Liners are geomembrane or plastic sheets that are unbreakable with two
feet of clay on the bottom and sides of the landfills.
• Operating practices such as compacting and covering waste frequently
with several inches of soil help decrease the smell; control litter,
insects, and rodents; and protect community health.
• Groundwater monitoring requires testing groundwater wells to
determine whether waste resources have escaped from the landfill.
• Closing and after they close the landfill care jobs include covering
landfills and providing long-term care of closed landfills.
• Corrective action controls and cleans up landfill releases and achieves
groundwater protection standards.
• Financial assurance offers funding for environmental protection during
and after landfill closes.
What do the landfill regulations enforce?
• Superfund’s is a government program that helps
clean up old landfills.
• The landfills that superfund cleans are the
landfills that begun before there were the landfill
regulations, which started in 1984, but weren’t
enforced until the 1990’s.
• One of the major superfund sites that was
cleaned up was PePe field. Pepe field was once a
chemical companies landfill, E.F. Drew Chemical
Company started dumping all of their waste into
the 3.5 acre field, superfund cleaned the place up
and now is a park, in New Jersey.
What is the Superfund site
Fresh Kills opened as a "temporary landfill" in 1947, The Fresh Kills
Landfill covers 2200 acres, it can be seen with the naked eye from space
and is taller then the Statue of Liberty, at a height of 225 ft. It is located
on the western shore of Staten Island and is made up of four sections
which hold fifty plus years of landfill, mostly in the form of household
waste. The waste disposed at the Fresh Kills Landfill and the rotting
products of this waste contain numerous chemicals.
The landfill officially closed in 2001. In late 2001 the landfill began
receiving the ruins of the World Trade Center catastrophe. It was used as
a work station for those who were involved in searching for any clues,
remains and remnants of the World Trade Centers. A virtual city was
constructed for those workers and volunteers, police and federal
investigators who worked determinedly to bring closure to a terrible
disaster. Through assembly lines, every bit of rubble was gone through
searching for human remains and clues. Fresh Kills now remains the
resting place of all the was shattered at the during World Trade Center
