[单项选择]Landfills
You have just finished your meal at a fast food restaurant and you throw your uneaten food, food wrappers, drink cups, utensils and napkins into the trash can. You don’t think about that waste again. On trash pickup day in your neighborhood, you push your can out to the curb, and workers dump the contents into a big truck and haul it away. You don’t have to think about that waste again, either. But maybe you have wondered, as you watch the trash truck pull away, just where that garbage ends up.Landfills are like compost piles in that they speed up decomposition of the buried trash.
A. °Sanitary landfill--landfill that uses a clay liner to isolate the trash from the environment
B. °Municipal solid waste (MSW) landfill—landfill that uses a synthetic (plastic) liner to isolate the trash from the environment.
C. Thepurpose 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 (腐烂) 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.
D. Proposingthe Landfill
E. Fora landfill to be built, the operators have to make sure that they follow certain steps. In most parts of the world, there are regulations that govern where a landfill can be placed and how it can operate. The whole process begins with someone proposing the landfill.
F. Inthe United States, taking care of trash and building landfills are local government responsibilities. Before a city or other authority can build a landfill, an environmental impact study must be done on the proposed site to determine:
G. ·the area of land necessary for the landfill
H. ·the composition of the underlying soil and bedrock
I. ·the flow of surface water over the site
J. ·the impact of the proposed landfill on the local environment and wildlife
K. ·the historical value of the proposed site
L. Buildingthe Landfill
M. Oncethe environmental impact study is complete, the permits are granted and the funds have been raised, then construction begins. 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 (环卫) services and the general public. After roads have been built, digging can begin. In the North Wake County Landfill, the landfill began 10 feet below the road surface.
N. WhatHappens to Trash in a Landfill
O. Trashput in a landfill will stay there for a very long time. Inside a landfill, there is little oxygen and little moisture. Under these conditions, trash does not break down very rapidly. In fact, when old landfills have been dug up or sampled, 40-year-old newspapers have been found with easily readable print. Landfills are not designed to break down trash, merely to bury it. When a landfill closes, the site, especially the groundwater, must be monitored and maintained for up to 30 years!
