A dynamic centrifuge test works to model the landfill in a scaled-down form. Typically in this approach, a small simplified landfill is constructed in a test box. During this testing, earthquake loading is simulated on the sample landfill. A major application of this type of testing is to observe the behavior of landfill liners during ground ...
In some older landfills, leachate was directed to the sewers, but this can cause a number of problems. Toxic metals from leachate passing through the sewage treatment plant concentrate in the sewage sludge, making it difficult or dangerous to dispose of the sludge without incurring a risk to the environment.
Leachate are fluid metabolic products from decomposition and contain various types of toxins and dissolved metallic ions. [6] If leachate escapes into the ground water it can cause health problems in both animals and plants. [7] [8] The volatile organic compounds (VOCs) are associated with causing smog and acid rain.

What causes earthquakes? Earthquakes occur when the plates that make up the Earth's crust move around. These plates, called tectonic plates, can push against each other.
Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...
Tsunamis can occur when an underwater earthquake rapidly displaces massive amounts of water, leading to a large, long wave that builds in intensity as it crosses the ocean.
A gas flare produced by a landfill in Lake County, Ohio. Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide.
Typically landfills try to keep oxygen levels to less than 5%, because higher levels can speed up decomposition, produce heat and raise the risk of an underground landfill fire.
