What purpose does this landfill have? didacbertomeu https://padlet.com/didacbertomeu/l6j0pa5bdil3/wish/318429147 The purpose of a landfill is to bury the trash in such a way that it will be isolated from groundwater, will be kept dry and will not be in contact with air. Under these conditions, trash will not decompose much. A landfill is not like a compost pile, where the purpose is to bury trash in such a way that it will decompose quickly.]]> 2019-01-08 17:16:33 UTC https://padlet.com/didacbertomeu/l6j0pa5bdil3/wish/318429147 2. Steps didacbertomeu https://padlet.com/didacbertomeu/l6j0pa5bdil3/wish/318435820 For a landfill to be built, the operators have to make sure that they follow certain steps:
1. First, it must be determined if there is sufficient land for the landfill.
2.Second, the composition of the underlying soil and bedrock must be determined.
3.Third, the flow of water over the area must be studied.
4.Fourth, you need to determine the potential effects of the landfill and possible contamination on local wildlife.
5.Finally, if the site contains any historical or archeological artifacts, you would not want to build a landfill there.]]> 2019-01-08 17:26:56 UTC https://padlet.com/didacbertomeu/l6j0pa5bdil3/wish/318435820 3. Building the Landfills didacbertomeu https://padlet.com/didacbertomeu/l6j0pa5bdil3/wish/318443879 First, access roads to the landfill site must be built if they do not already exist. These roads will be used by construction equipment, sanitation services and the general public. After roads have been built, then the landfill can be excavated. In the North Wake County Landfill, the landfill began 10 feet below the road surface.]]> 2019-01-08 17:38:40 UTC https://padlet.com/didacbertomeu/l6j0pa5bdil3/wish/318443879 4. Parts of a Landfill didacbertomeu https://padlet.com/didacbertomeu/l6j0pa5bdil3/wish/318448449
  • Bottom liner system - separates trash and subsequent leachate from groundwater
  • Cells (old and new) - where the trash is stored within the landfill
  • Storm water drainage system - collects rain water that falls on the landfill
  • Leachate collection system - collects water that has percolated through the landfill itself and contains contaminating substances (leachate)
  • Methane collection system - collects methane gas that is formed during the breakdown of trash
  • Covering or cap - seals off the top of the landfill
