A shaking table laboratory test works to explore the strength characteristics at interfaces between different components of the landfill. Of primary concern is the contact between soil and landfill liner, as this is usually considered to be a weak point in the system. [4] A dynamic centrifuge test works to model the landfill in a scaled-down form.
The drums and cartons containing these chemicals were deposited in trenches that were 15 feet (4.6 m) deep and 12 to 15 feet (4.6 m) wide and covered with approximately 3 feet (0.91 m) of soil. Velsicol took no precautions to insure the drums from bursting and, invariably, some of the drums would leak their contents into the soil.
A garbage landslide [1] is a man-made event that occurs when poorly managed garbage mounds at landfills collapse with similar energy to natural landslides.These kinds of slides can be catastrophic as they sometimes occur near communities of people, often being triggered by weather or human interaction.

Class Two landfills can accept waste that tests at less than 10 times the maximum contaminant levels. Any waste that can decay must be removed from Class Two landfills within 72 hours.
Sites include landfills, mines, manufacturing facilities, processing plants where toxic waste has either been improperly managed or dumped. They were designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980.
4 c 6 h 10 o 4 + 6 h 2 o → 13 ch 4 + 11 co 2 On average, about half of the volumetric concentration of landfill gas is CH 4 and slightly less than half is CO 2 . The gas also contains about 5% molecular nitrogen (N 2 ), less than 1% hydrogen sulfide (H 2 S), and a low concentration of non-methane organic compounds (NMOC) , about 2700 ppmv .
[4] In the European Union, the Urban Waste Water Treatment Directive allows sewage sludge to be sprayed onto land. The volume is expected to double to 185,000 tons of dry solids in 2005. This has good agricultural properties due to the high nitrogen and phosphate content. In 1990/1991, 13% wet weight was sprayed onto 0.13% of the land; however ...
The second chapter considers the intersection of race, class, and place.In particular, Bullard alludes to four cases (Chemical Waste Management, SCA Services, Industrial Chemical Company, and Warren County PCB Landfill) to depict how the siting of toxic waste facilities and landfills often burdens communities with high percentages of poor, elderly, young, and minority (mainly black) residents.
