Background: Municipal Solid Waste (MSW) is all of the garbage, refuse, trash or junk that gets thrown away from our homes or small businesses. All of this MSW is collected and taken away. Have you wondered where it goes? In the 1950's and 60's it went to open dumps. In the 1970's landfills were established but there were problems, and today there is new legislation and technology to better manage this waste.

I need a review the history of MSW.

1) Describe an open dump. Explain the environmental problems.

2) Describe an early landfill. What are the problems associated with early landfills? Include a discussion of leachate, methane, incomplete decomposition and settling.

3) Describe a modern landfill. What are the differences as compared to early landfills? What improvements have been made?

4) Choose one of these landfills and explain the innovations being implemented to make the landfill more productive and to reduce its environmental impact:

- Marionhill Landfill, South Africa
- Peuntes Hills, California
- Alamonte Landfill, CA
- Tessman Road Landfill, TX

A Review the History of Municipal Solid Waste

1) Describe an open dump. Explain the environmental problems.
An open dump is a place to put unwanted material that has no use and needs to be disposed of. These unwanted items are put on land to decompose or merely out of sight. Open dump areas are foul smelling infested with rats and flies.

2) Describe an early landfill. What are the problems associated with early landfills? Include a discussion of leachate, methane, incomplete decomposition and settling.
The early landfills accepted all material, including hazardous waste products. Methane gas was released into the air when microorganisms decomposed the solid waste. The early landfills were burned, polluting the air with acid rain. Liquid leachate traveled to the soil, surface water and groundwater. Hazardous material in the leachate often contaminated soil and water. Incomplete decomposition, left as ash, generally contained high concentrations of toxic substance.

3) Describe a modern landfill. What are the differences as compared to early landfills? What improvements have been made?
Modern ...
