Modern Landfill Engineering

SUMMARY:  A landfill is not a dump; it is a disposal ecosystem complete with living microbes working to break down garbage, numerous civil, hydraulic, and environmental challenges with millions of dollars invested in proper design and operation. A landfill is forever and when done correctly, it provides an important service to the community without negatively affecting the environment.
