Landfill Problems:  Landfill Problems By: Team ~ Super Chicks Granular Drainage Layer :  Granular Drainage Layer 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 garbage) Slide3:  Geomembrane 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 20 years Slide4:  What has the EPA admitted about the geomembrane? Slide5:  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. Slide6:  The foundation is the lowest level in the landfill 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. Slide7:  1.What is Leachete? a. The vegetation that grows on a landfill b. The liquid that flows through the landfill The dirt/sand or any kind of mud on a landfill Fill in the Blank: The foundation of a landfill is the _______ level. Slide8:  3. About How many feet Deep is the Clay Layer? 2 Feet 5 feet 3 1/2 feet 4 feet Slide9:  Methane gas is a green house gas. 37% of the methane are from landfills Only danger taken into account are explosions Slide10:  How is Methane dangerous to the earth? Trash Incineration (burn):  Trash Incineration (burn) Only 10-20% of hazardous wastes can be safely incinerated There are some state operated trash incinerators that convert the energy produced by the burning trash into usable energy When the trash is burned, it leaves behind ashes The ashes are often buried under different circumstances They are sometimes mixed in with pavement Sometimes they are dumped into holes in the ground Often they are dumped in a LANDFILL Incineration Problems:  Incineration Problems 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 groundwater 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 Now What Did You Learn?:  Now What Did You Learn? 1)What does INCINERARTION mean? (a. bur n (b. cover up (c. movement of trash (d. convert to energy _____________________________________________ 2)What percent of HAZARDOUS wastes can be incinerated? (a. 60-90% (b. 40-70% (c. 20-50% (d. 10-20% Slide14:  Landslides 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 dangerous Places where landslides have occurred since 2004 are Haiti, Kyrgyzstan, Peru, China, Colorado, Indonesia, Vietnam, Ecuador, Kazakhstan, California, Pakistan, Washington, and Pennsylvania Slide15:  About how much does a landslide cost in repair? Landslide Entering the Valley Starting of a Landslide Landfill Regulations:  Landfill Regulations 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. Slide17:  What do the landfill regulations enforce? Superfund’s:  Superfund’s 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. Slide19:  What is the Superfund site project? Fresh Kills:  Fresh Kills 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 disaster. Slide21:  What is Fresh Kills Home to?
