  2. Seismic response of landfill - Wikipedia

    en.wikipedia.org/wiki/Seismic_response_of_landfill

    Solid waste landfills can be affected by seismic activity. The tension in a landfill liner rises significantly during an earthquake, and can lead to stretching or tearing of the material. [1] The top of the landfill may crack, and methane collection systems can be moved relative to the cover. [2]

  3. Leachate - Wikipedia

    en.wikipedia.org/wiki/Leachate

    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.

  4. Toxicity characteristic leaching procedure - Wikipedia

    en.wikipedia.org/wiki/Toxicity_characteristic...

    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 ...

    en.wikipedia.org/wiki/Chiquita_Canyon_Landfill

    The landfill’s containment systems were overwhelmed with rainwater filtering through the rotting garbage. Oxygen may have intruded below the landfill cover causing the generation of extreme heat, production of excessive leachate, and the buildup of pressure within a 35-acre closed portion (14 ha) of the site.

  6. Landfill - Wikipedia

    en.wikipedia.org/wiki/Landfill

    Once a landfill site is full, it is sealed off to prevent precipitation ingress and new leachate formation. However, liners must have a lifespan, be it several hundred years or more. Eventually, any landfill liner could leak, [7] so the ground around landfills must be tested for leachate to prevent pollutants from contaminating groundwater.

    Earthquakes account for about 65% of the risk for a worst-case scenario meltdown. Potential internal fires at the plant make up another 18%. The last 17% is made up of everything from aircraft ...

    Now fire officials are working to determine the full scope of the ruin. "It's a big system shock, almost like you're in a bad dream," said resident Brittanie Bibby. "You just want to wake up."

  9. Landfill liner - Wikipedia

    en.wikipedia.org/wiki/Landfill_liner

    A landfill liner, or composite liner, is intended to be a low permeable barrier, which is laid down under engineered landfill sites. Until it deteriorates, the liner retards migration of leachate , and its toxic constituents, into underlying aquifers or nearby rivers from causing potentially irreversible contamination of the local waterway and ...
