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.
The landfill in Lebanon, operated by the city, had leachate breakouts in 13 areas, including five releases beyond the facility and into the environment, according to a letter DES sent in April.
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]
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.
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 ...
Moderately damaging earthquakes strike between New York and Wilmington, Delaware, about twice a century, the USGS said, and smaller earthquakes are felt in the region roughly every two to three years.
Leachate water frequently has elevated levels of tritium compared to background groundwater and a leachate (water) release would increase tritium levels in affected groundwater samples, while landfill gas has been shown not to do so. Although landfill gas components can react with minerals and alter inorganic constituents present in groundwater ...
"We shouldn’t forget the climate itself can also play a role in changing the stress state at depth where earthquakes are happening." The study does not say that changes in climate or weather are ...
