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]
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.
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 ...
Old Navy Dump/Manchester Lab (USEPA/NOAA) Kitsap: Former US Navy site. Firefighting training contaminated soil with dioxins and petroleum hydrocarbons. Hydraulic erosion of a landfill area contaminated sediments and shellfish in Clam Bay with PCBs, copper, lead and zinc. Seeps from the landfill contained elevated levels of copper, nickel, zinc ...
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.
Wise County officials are concerned that a proposed construction waste landfill planned for a a rapidly growing near Boyd and Aurora could affect the West Fork of the Trinity River, a major water ...
Hydraulic fracturing is a driver of climate change. [4] [29] However, whether natural gas produced by hydraulic fracturing causes higher well-to-burner emissions than gas produced from conventional wells is a matter of contention. Some studies have found that hydraulic fracturing has higher emissions due to methane released during completing ...
The model accounts for above-ground factors that change the pressure within the rock underneath — such as seasonal sea-level changes, fluctuations in atmospheric pressure and heavy rain or snow ...
